I am intending to do a series of posts highlighting interviews with Philadelphia area biotech startup CEO’s and show how a vibrant biotech startup scene is evolving in the city as well as the Delaware Valley area. Philadelphia has been home to some of the nation’s oldest biotechs including Cephalon, Centocor, hundreds of spinouts from a multitude of universities as well as home of the first cloned animal (a frog), the first transgenic mouse, and Nobel laureates in the field of molecular biology and genetics. Although some recent disheartening news about the fall in rankings of Philadelphia as a biotech hub and recent remarks by CEO’s of former area companies has dominated the news, biotech incubators like the University City Science Center and Bucks County Biotechnology Center as well as a reinvigorated investment community (like PCCI and MABA) are bringing Philadelphia back. And although much work is needed to bring the Philadelphia area back to its former glory days (including political will at the state level) there are many bright spots such as the innovative young companies as outlined in these posts.

First up I got to talk with Florian Schodel, M.D., Ph.D., CEO of Philimmune, which provides expertise in medicine, clinical and regulatory development and analytical sciences to support successful development and registration of vaccines and biologics. Before founding Philimmune, Dr. Schodel was VP in Vaccines Clinical Research of Merck Research Laboratories and has led EU vaccine clinical trials and the clinical development of rotavirus, measles, mumps, hepatitis B, and rubella vaccines. In addition Dr. Schodel and Philimmune consult on several vaccine development efforts at numerous biotech companies including:

 

\His specialties and services include: vaccines and biologics development strategy, clinical development, clinical operations, strategic planning and alliances, international collaborations, analytical and assay development, project and portfolio integration and leadership.

Successful development of vaccines and biologics poses some unique challenges: including sterile manufacturing and substantial early capital investment before initiated clinical trials, assay development for clinical trial support, and unique trail design. Therefore vaccines and biologics development is a highly collaborative process between several disciplines.

The Philadelphia area has a rich history in vaccine development including the discovery and development of the rubella, cytomegaolovirus, a rabies, and the oral polio vaccine at the Wistar Institute. Dr. Schodel answered a few questions on the state of vaccine development and current efforts in the Philadelphia area, including recent efforts by companies such as GSK’s efforts and Inovio’s efforts developing an Ebola vaccine.

In his opinion, Dr. Schodel believes our biggest hurdle in vaccine development in a societal issue, not a preclinic development issue. Great advances have been made to speed the discovery process and enhance quality assurance of manufacture capabilities like

however there has not been a great history or support for developing vaccines for the plethora of infectious diseases seen in the developing world. As Dr. Schodel pointed out, there are relatively few players in the field, and tough to get those few players excited for investing in new targets.

 

However, some companies are rapidly expanding their vaccine portfolios including

 

 

Why haven’t 3rd world countries developed their own vaccine programs?

 

  1. Hard to find partners willing to invest and support development
  2. Developing nations don’t have the money or infrastructure to support health programs
  3. Doctors in these countries need to be educated on how to conduct trials, conduct vaccine programs like Gates Foundation does. For more information see Nature paper on obstacles to vaccine introduction in third world countries.

 

Lastly, Dr. Schodel touched on a growing area, cancer vaccine development. Recent advances in bladder cancer vaccine, cervical, and promising results in an early phase metastatic breast cancer vaccine trial and phase I oral cancer vaccine trial have reinvigorated this field of cancer vaccinology.

Peer Review and Health Care Issues

Larry H. Bernstein, MD, FCAP, Reporter

http://pharmaceuticalintelligence.com/12/1/2014/Peer-Review-and-Health-Care-Issues

(Medscape – Dec 1, 2014)

Peer-reviewed journals retracted 110 papers over the last 2 years. Nature reports the grim details in “Publishing: the peer review scam”.

When a handful of authors were caught reviewing their own

papers, it exposed weaknesses in modern publishing systems.

Editors are trying to plug the holes.

 

The Hill reports that the FDA may lift its ban on blood donations from gay men. The American Red Cross has voiced its support for lifting of the ban.

Advisers for the Food and Drug Administration (FDA) will meet this week to decide whether gay men should be allowed to donate blood, the agency’s biggest step yet toward changing the 30-year-old policy.

If the FDA accepts the recommendation, it would roll back a policy that has been under strong pressure from LGBT advocates and some members of Congress for more than four years.

“We’ve got the ball rolling. I feel like this is a tide-turning vote,” said Ryan James Yezak, an LGBT activist who founded the National Gay Blood Drive and will speak at the meeting. “There’s been a lot of feet dragging and I think they’re realizing it now.”

Groups such as the American Red Cross and America’s Blood Centers also voiced support of the policy change this month, calling the ban “medically and scientifically unwarranted.”

The FDA will use the group’s recommendation to decide whether to change the policy.

“Following deliberations taking into consideration the available evidence, the FDA will issue revised guidance, if appropriate,” FDA spokeswoman Jennifer Rodriguez wrote in a statement.

This reporter has more than 20 years of Blood Bank experience.  The factor in favor of the recommendation is that the HIV 1/2 and other testing is accurate enough to leave the question of donor lifestyle irrelevant.  However, it remains to be seen whether the testing turnaround time is sufficient to prevent the release of units that may be contaminated prior to transfusion, which is problematic for platelets, that have short expirations. In all cases of donor infection, regardless of whether units are released, a finding leads to not releasing the product or to recall.

 

Democrats made a strategic mistake by passing the Affordable Care Act, Sen. Charles Schumer (N.Y.), the third-ranking member of the Senate Democratic leadership, said Tuesday.

Schumer says Democrats “blew the opportunity the American people gave them” in the 2008 elections, a Democratic landslide, by focusing on healthcare reform instead of legislation to boost the middle class.

“After passing the stimulus, Democrats should have continued to propose middle class-oriented programs and built on the partial success of the stimulus,” he said in a speech at the National Press Club.

He said the plight of uninsured Americans caused by “unfair insurance company practices” needed to be addressed, but it wasn’t the change that people wanted when they elected Barack Obama as president.

“Americans were crying out for an end to the recession, for better wages and more jobs; not for changes in their healthcare,” he said.

This reader finds the observation by Senator Schumer very perceptive, regardless of whether the observation in hindsight might have had a different political outcome.  It has been noted that President Obama had a lot on his plate.  Moreover, we have not seen such a poor record of legislation in my lifetime.  There are underlying issues of worldview of elected officials that also contribute to the events.

 

THE PEER-REVIEW SCAM

BY CAT FERGUSON, ADAM MARCUS AND IVAN ORANSKY

N AT U R E |  2 7 N O V  2 0 1 4; VO L 5 1 5 : 480-82.

Most journal editors know how much effort it takes to persuade busy researchers to review a paper. That is why the editor of The Journal of Enzyme Inhibition and Medicinal Chemistry was puzzled by the reviews for manuscripts by one author — Hyung-In Moon, a medicinal-plant researcher then at Dongguk University in Gyeongju, South Korea.

The reviews themselves were not remarkable: mostly favourable, with some suggestions about how to improve the papers. What was unusual was how quickly they were completed — often within 24 hours. The turnaround was a little too fast, and Claudiu Supuran, the journal’s editor-in-chief, started to become suspicious.

In 2012, he confronted Moon, who readily admitted that the reviews had come in so quickly because he had written many of them himself. The deception had not been hard to set up. Supuran’s journal and several others published by Informa Healthcare in London
invite authors to suggest potential reviewers for their papers. So Moon provided names, sometimes of real scientists and sometimes pseudonyms, often with bogus e-mail addresses that would go directly to him or his colleagues. His confession led to the retraction of 28 papers by several Informa journals, and the resignation of an editor.

Moon’s was not an isolated case. In the past 2 years, journals have been forced to retract more than 110 papers in at least 6 instances of peer-review.

PEER-REVIEW RING
Moon’s case is by no means the most spectacular instance of peer-review rigging in recent years. That honour goes to a case that came to light in May 2013, when Ali Nayfeh, then editor-in-chief of the Journal of Vibration and Control, received some troubling news. An author who had submitted a paper to the journal told Nayfeh that he had received e-mails about it from two people claiming to be reviewers. Reviewers do not normally have direct contact with authors, and — strangely — the e-mails came from generic-looking Gmail accounts rather than from the professional institutional accounts that many academics use (see ‘Red flags in review’).
Nayfeh alerted SAGE, the company in Thousand Oaks, California, that publishes the journal. The editors there e-mailed both the Gmail addresses provided by the tipster, and the institutional addresses of the authors whose names had been used, asking for proof of identity and a list of their publications.ew rigging. What all these cases had in common was that researchers exploited vulnerabilities in the publishers’ computerized systems to dupe editors into accepting manuscripts, often by doing their own reviews. The cases involved publishing behemoths Elsevier, Springer, Taylor & Francis, SAGE and Wiley, as well as Informa, at least one of the systems — could make researchers vulnerable to even more serious identity theft. “For a piece of software that’s used by hundreds of thousands of academics worldwide, it really is appalling,” says Mark Dingemanse, a linguist at the Max Planck Institute for Psycholinguistics in Nijmegen, the Netherlands, who has used some of these programs to publish and review papers.

A 14-month investigation that came to involve about 20 people from SAGE’s editorial, legal and production departments. It showed that the Gmail addresses were each linked to accounts with Thomson Reuters’ ScholarOne, a publication-management system used by SAGE and several other publishers, including Informa. Editors were able to track every paper that the person or people behind these accounts had allegedly written or reviewed, says SAGE spokesperson Camille Gamboa. They also checked the wording of reviews, the details of author-nominated reviewers, reference lists and the turnaround time for reviews (in some cases, only a few minutes). This helped the investigators to ferret out further suspicious-looking accounts; they eventually found 130.

SAGE investigators came to realize that authors were both reviewing and citing each other at an anomalous rate. Eventually, 60 articles were found to have evidence of peer-review tampering, involvement in the citation ring or both. “Due to the serious nature of the findings, we wanted to ensure we had researched all avenues as carefully as possible before contacting any of the authors and reviewers,” says Gamboa. When the dust had settled, it turned out that there was one author in the centre of the ring: Peter Chen, an engineer then at the National Pingtung University of Education (NPUE) in Taiwan, who was a co-author on practically all of the papers in question.

PASSWORD LOOPHOLE
Moon and Chen both exploited a feature of ScholarOne’s automated processes. When a reviewer is invited to read a paper, he or she is sent an e-mail with login information. If that communication goes to a fake e-mail account, the recipient can sign into the system under whatever name was initially submitted, with no additional identity verification. Jasper Simons, vice-president of product and market strategy for Thomson Reuters in Charlottesville, Virginia, says that ScholarOne is a respected peer-review system and that it is the responsibility of journals and their editorial teams to invite properly qualified reviewers for their papers.

ScholarOne is not the only publishing system with vulnerabilities. Editorial Manager, built by Aries Systems in North Andover, Massachusetts, is used by many societies and publishers, including Springer and PLOS. The American Association for the Advancement of Science in Washington DC uses a system developed in-house for its journals Science, Science Translational Medicine and Science Signaling, but its open-access offering, Science Advances, uses Editorial Manager. Elsevier, based in Amsterdam, uses a branded version of the same product, called the Elsevier Editorial System.

Usually, editors in the United States and Europe know the scientific community in those regions well enough to catch potential conflicts of interest between authors and reviewers. But Lindsay says that Western editors can find this harder with authors from Asia — “where often none of us knows the suggested reviewers”. In these cases, the journal insists on at least one independent reviewer, identified and invited by the editors.

When Dr. Jeffery Ward, a cancer specialist, and his partners sold their private practice to the Swedish Medical Center in Seattle, the hospital built them a new office suite 50 yards from the old place. The practice was bigger, but Dr. Ward saw the same patients and provided chemotherapyjust like before. On the surface, nothing had changed but the setting.

But there was one big difference. Treatments suddenly cost more, with higher co-payments for patients and higher bills for insurers. Because of quirks in the payment system, patients and their insurers pay hospitals and their doctors about twice what they pay independent oncologists for administering cancer treatments.

There also was a hidden difference — the money made from the drugs themselves. Cancer patients and their insurers buy chemotherapy drugs from their medical providers. Swedish Medical Center, like many other others, participates in a federal program that lets it purchase these drugs for about half what private practice doctors pay, greatly increasing profits.

Oncologists like Dr. Ward say the reason they are being forced to sell or close their practices is because insurers have severely reduced payments to them and because the drugs they buy and sell to patients are now so expensive. Payments had gotten so low, Dr. Ward said, that they only way he and his partners could have stayed independent was to work for free. When he sold his practice, Dr. Ward said, “The hospital was a refuge, not the culprit.”

When a doctor is affiliated with a hospital, though, patients end up paying, out of pocket, an average $134 more per dose for the most commonly used cancer drugs, according to a report by IMS Health, a health care information company. And, the report notes, many cancer patients receive multiple drugs.

“Say there was a Costco that had very good things at reasonable prices,” said Dr. Barry Brooks, a Dallas oncologist in private practice. “Then a Neiman Marcus comes in and changes the sign on the door and starts billing twice as much for the same things.” That, he said, is what is happening in oncology.

The situation is part of the unusual world of cancer medicine, where payment systems are unique and drive not just the price of care but what drugs patients may get and where they are treated. It raises questions about whether independent doctors, squeezed by finances, might be swayed to use drugs that give them greater profits or treat poorer patients differently than those who are better insured.

But one thing is clear: The private practice oncologist is becoming a vanishing breed, driven away by the changing economics of cancer medicine.

Practices are making the move across the nation. Reporting on the nation’s 1,447 independent oncology practices, the Community Oncology Alliance, an advocacy group for independent practices, said that since 2008, 544 were purchased by or entered contractual relationships with hospitals, another 313 closed and 395 reported they were in tough financial straits. In western Washington, just one independent oncology group is left.

Christian Downs, executive director of the Association of Community Cancer Centers, said that although there are no good data yet, he expected the Affordable Care Act was accelerating the trend. Many people bought inadequate insurance for the expensive cancer care they require. Community doctors have to buy the drugs ahead of time, placing a burden on them when patients cannot pay. The act also requires documentation of efficiencies in medical care which can be expensive for doctors in private practice to provide. And it encourages the consolidation of medical practices.

The American Hospital Association cites advantages for patients being treated by hospital doctors. “The hassle factor is reduced,” said Erik Rasmussen, the association’s vice president of legislative affairs. Patients can have scans, like CT and M.R.I., use a pharmacy and get lab tests all in one place instead of going from facility to facility, he said.

And, he added, there is a reason hospitals get higher fees for their services — it compensates them for staying open 24 hours and caring for uninsured and underinsured patients.

For doctors in private practice, providing chemotherapy to uninsured and Medicaid patients is a money loser. As a result, many, including Dr. Ward before he sold his practice, end up sending those patients to nearby hospitals for chemotherapy while keeping them as patients for office visits.

“We hate doing it, I can’t tell you how much we hate doing it,” said Dr. Brooks, the Texas oncologist. “But I tell them, ‘It will cost me $200 to give you this medication in my office, so I am going to ask you to go to the hospital as an outpatient for infusions.’ ”

Dr. Peter Eisenberg, in private practice in Marin County in Northern California, said: “The disgrace is that we have to treat people differently depending on how much money they’ve got. That we do diminishes me.”

Hospitals may be less personal and less efficient, said Dr. Richard Schilsky, chief medical officer at the American Society of Clinical Oncology. Many private practice oncology offices, he said, “Run on time, they are efficient, you get in, you get out, as opposed to academic medical centers where they may be an hour and a half behind.”

Dr. Ward and others in private practice said they tried for years to make a go of it but were finally defeated by what he described as “a series of cuts in oncology reimbursement under the guise of reform to which private practice is most vulnerable.”

Lower reimbursements have two effects. One is on overhead. Unlike other doctors, oncologists stock their own drugs, maintaining a sort of mini-pharmacy. If a patient gets too sick to receive a drug or dies, the doctor takes the loss. That used to be acceptable because insurers paid doctors at least twice the wholesale price of drugs. Now doctors are reimbursed for the average cost of the drug plus 4.3 percent, there are more and more drugs to stock, and drugs cost more.

“The overhead is enormous,” Dr. Schilsky said. “This is one of the reasons why many oncologists are becoming hospital-based.”

The second — and bigger — effect is less profit from selling drugs to patients. For years, chemotherapy drugs provided a comfortable income. Those days are gone, doctors say.

The finances are very different in hospitals, with their

  • higher reimbursement rates for administering drugs,
  • discounts for buying large quantities, and
  • a special federal program that about 30 percent of hospitals qualify for.
  • The program, to compensate research hospitals and hospitals serving poor people,
  • lets hospitals buy chemotherapy drugs for all outpatients at about a 50 percent discount.

In addition, Dr. Schilsky notes, cancer patients at hospitals use other services, like radiation therapy, imaging and surgery.

“A cancer patient is going to generate a lot of revenue for a hospital,” Dr. Schilsky said.

Health care economists say they have little data on how the costs and profits from selling chemotherapy drugs are affecting patient care. Doctors are constantly reminded, though, of how much they can make if they buy more of a company’s drug.

Celgene, for example, in a recent email about its drug Abraxane, told one doctor who had bought 50 vials that he could get a rebate of $647.51 by buying 68 vials. If he bought 175 vials he’d get $1,831.93

This hidden profit possibility troubles Dr. Peter B. Bach, director of the Center for Health Policy and Outcomes at Memorial Sloan Kettering Cancer Center.

“When you walk into a doctor’s office you don’t know that in most cancer scenarios there are a range of therapeutic choices,” Dr. Bach said. “Unless the doctor presents options, you assume there aren’t any.”

While individual oncologists deny choosing treatments that provide them with the greatest profit, Dr. Kanti Rai, a cancer specialist at North Shore-Long Island Jewish Cancer Center, said it would be foolish to believe financial considerations never influence doctors’ choices of drugs.

“Sometimes hidden in such choices — and many times not so hidden — are considerations of what also might be financially more profitable,” he said.

Remote Care Management of CHF Patients by Home Digital Technology and Continuous Access to NP – A Partnership of an Insurer with a Technology Company

 

Reporter: Aviva Lev-Ari, PhD, RN

 

CIGNA-HEALTHSPRING AND INTEL-GE CARE INNOVATIONS™ EXPAND REMOTE CARE MANAGEMENT PROGRAM TO REDUCE CONGESTIVE HEART FAILURE-RELATED COMPLICATIONS IN TENNESSEE

02 October 2014
  • Completion of successful pilot prompts statewide program expansion in TN
  • Program helps monitor and educate participants, promotes self-monitoring and empowers patient engagement with their health
  • Participants receive interactive tablet, blood pressure cuff and scale at no extra cost
  • Key to program success is customer’s direct access to dedicated Cigna-HealthSpring nurse practitioner with virtual connection enabled through interactive tablet

NASHVILLE – October 2, 2014 – In partnership with Intel-GE Care Innovations™, Cigna-HealthSpring® is expanding its population health program that utilizes interactive tablets – the Intel-GE Care Innovations™ Guide – and virtual connection to Cigna-HealthSpring nurse practitioners to partner and engage with patients diagnosed with congestive heart failure (CHF) to successfully manage their condition at home. Based on a successful pilot in Middle Tennessee that engaged 50 patients, the innovative remote patient management program is now being implemented with 250 patients statewide with potential for further expansion.

“We are dedicated to helping our customers get more from life and the success of the pilot program shows what an invaluable opportunity we have to truly make a positive impact in our customers’ lives,” said Dr. Jim Lancaster, senior medical director for Cigna-HealthSpring of Tennessee. “Many people with congestive heart failure find themselves back in the hospital within a matter of weeks after returning home so it’s important that we continue to seek new and innovative solutions to help them better manage their health. We are pleased by the early success of the pilot program and excited to implement it statewide to help more of our customers take control of their health with the convenience of virtual yet personalized medicine at home.”

Under the expanded program, participating Cigna-HealthSpring customers will be given a blood pressure cuff, scale and interactive tablet for a minimum of 90 days which will enable them to interact virtually with their Cigna-HealthSpring nurse practitioner, track their daily biometrics and complete an educational program to help them manage their CHF at home. Once they achieve specific milestones, participants will transition away from the tablet to a less intensive program where they will continue to monitor and log their weight and blood pressure with the help of a case manager. At the end of the program, customers should be able to recognize symptoms of CHF exacerbation and understand the impact of diet, education and medication on their condition. To participate in the program, customers must have received a CHF diagnosis and a previous ER visit or hospital admission. There is no cost to the customer to participate in the program but using the tablet requires a landline or internet connectivity.

“We have seen dramatic reductions in the need for hospitalization in our first year of the program pilot with Cigna-HealthSpring. We also recently worked with many hospitals across the country to create successful remote care management programs and have seen as high as a 75 percent reduction in hospital readmissions,” said Sean Slovenski, CEO of Intel-GE Care Innovations. “We’ve learned that a successful program is as much about the logistical details as it is about the technology. Helping consumers engage proactively in their own health is our mission at Care Innovations. By monitoring and engaging CHF patients as they go about their daily lives, we are able to catch problems early, involve the doctor immediately and ultimately avoid unnecessary ER visits, hospital stays and worsening of the patients’ health.”

Cigna-HealthSpring customer success examples:

When Elizabeth*, 74, started the program her blood pressure was extremely high, she was overweight and she had struggled with hospital admissions due to CHF complications. Since starting the program, she has lost 25 pounds, consistently had her blood pressure and heart rate in a healthy range and avoided the hospital. She says the program has helped give her better awareness of her condition and made her realize the positive impact she can make from simple daily monitoring of her biometrics. Elizabeth’s improvement has also helped her husband, who acts as her caregiver, gain more comfort and assurance that she has personal and direct access to her Cigna-HealthSpring nurse practitioner.

Margery*, 72, had struggled with controlling her CHF and frequently found herself in the hospital. Cigna-HealthSpring worked together with her cardiologist to enroll her in the program and create a personalized care plan to better manage her CHF. She says she now knows what to do and the program has helped educate and empower her to take better care of her herself and control her CHF. The program has helped her improve her biometrics, avoid the hospital for CHF-related complications and allowed her nurse practitioner to intervene early to prevent CHF exacerbation or a trip to the hospital.

*Names changed for privacy.

CHF is a chronic condition that affects 5.1 million people in the U.S.[1] and costs Medicare $17.4 billion per year in avoidable hospital readmissions.[2]. A companion piece to a recent study by Dartmouth University listed some of the reasons for hospital readmissions regardless of the condition, including patients not fully understanding their condition and being confused about medications.[3]

“What makes this program so special is that customers know they have easy and direct access to a Cigna-HealthSpring nurse practitioner, someone who truly cares about them and their health,” added Dr. Lancaster. “They feel empowered to learn how they can impact their own health.”

Imaging-guided cancer treatment

Imaging-guided cancer treatment

Writer & reporter: Dror Nir, PhD

It is estimated that the medical imaging market will exceed $30 billion in 2014 (FierceMedicalImaging). To put this amount in perspective; the global pharmaceutical market size for the same year is expected to be ~$1 trillion (IMS) while the global health care spending as a percentage of Gross Domestic Product (GDP) will average 10.5% globally in 2014 (Deloitte); it will reach ~$3 trillion in the USA.

Recent technology-advances, mainly miniaturization and improvement in electronic-processing components is driving increased introduction of innovative medical-imaging devices into critical nodes of major-diseases’ management pathways. Consequently, in contrast to it’s very small contribution to global health costs, medical imaging bears outstanding potential to reduce the future growth in spending on major segments in this market mainly: Drugs development and regulation (e.g. companion diagnostics and imaging surrogate markers); Disease management (e.g. non-invasive diagnosis, guided treatment and non-invasive follow-ups); and Monitoring aging-population (e.g. Imaging-based domestic sensors).

In; The Role of Medical Imaging in Personalized Medicine I discussed in length the role medical imaging assumes in drugs development.  Integrating imaging into drug development processes, specifically at the early stages of drug discovery, as well as for monitoring drug delivery and the response of targeted processes to the therapy is a growing trend. A nice (and short) review highlighting the processes, opportunities, and challenges of medical imaging in new drug development is: Medical imaging in new drug clinical development.

The following is dedicated to the role of imaging in guiding treatment.

Precise treatment is a major pillar of modern medicine. An important aspect to enable accurate administration of treatment is complementing the accurate identification of the organ location that needs to be treated with a system and methods that ensure application of treatment only, or mainly to, that location. Imaging is off-course, a major component in such composite systems. Amongst the available solution, functional-imaging modalities are gaining traction. Specifically, molecular imaging (e.g. PET, MRS) allows the visual representation, characterization, and quantification of biological processes at the cellular and subcellular levels within intact living organisms. In oncology, it can be used to depict the abnormal molecules as well as the aberrant interactions of altered molecules on which cancers depend. Being able to detect such fundamental finger-prints of cancer is key to improved matching between drugs-based treatment and disease. Moreover, imaging-based quantified monitoring of changes in tumor metabolism and its microenvironment could provide real-time non-invasive tool to predict the evolution and progression of primary tumors, as well as the development of tumor metastases.

A recent review-paper: Image-guided interventional therapy for cancer with radiotherapeutic nanoparticles nicely illustrates the role of imaging in treatment guidance through a comprehensive discussion of; Image-guided radiotherapeutic using intravenous nanoparticles for the delivery of localized radiation to solid cancer tumors.

 Graphical abstract

 Abstract

One of the major limitations of current cancer therapy is the inability to deliver tumoricidal agents throughout the entire tumor mass using traditional intravenous administration. Nanoparticles carrying beta-emitting therapeutic radionuclides [DN: radioactive isotops that emits electrons as part of the decay process a list of β-emitting radionuclides used in radiotherapeutic nanoparticle preparation is given in table1 of this paper.) that are delivered using advanced image-guidance have significant potential to improve solid tumor therapy. The use of image-guidance in combination with nanoparticle carriers can improve the delivery of localized radiation to tumors. Nanoparticles labeled with certain beta-emitting radionuclides are intrinsically theranostic agents that can provide information regarding distribution and regional dosimetry within the tumor and the body. Image-guided thermal therapy results in increased uptake of intravenous nanoparticles within tumors, improving therapy. In addition, nanoparticles are ideal carriers for direct intratumoral infusion of beta-emitting radionuclides by convection enhanced delivery, permitting the delivery of localized therapeutic radiation without the requirement of the radionuclide exiting from the nanoparticle. With this approach, very high doses of radiation can be delivered to solid tumors while sparing normal organs. Recent technological developments in image-guidance, convection enhanced delivery and newly developed nanoparticles carrying beta-emitting radionuclides will be reviewed. Examples will be shown describing how this new approach has promise for the treatment of brain, head and neck, and other types of solid tumors.

The challenges this review discusses

  • intravenously administered drugs are inhibited in their intratumoral penetration by high interstitial pressures which prevent diffusion of drugs from the blood circulation into the tumor tissue [1–5].
  • relatively rapid clearance of intravenously administered drugs from the blood circulation by kidneys and liver.
  • drugs that do reach the solid tumor by diffusion are inhomogeneously distributed at the micro-scale – This cannot be overcome by simply administering larger systemic doses as toxicity to normal organs is generally the dose limiting factor.
  • even nanoparticulate drugs have poor penetration from the vascular compartment into the tumor and the nanoparticles that do penetrate are most often heterogeneously distributed

How imaging could mitigate the above mentioned challenges

  • The inclusion of an imaging probe during drug development can aid in determining the clearance kinetics and tissue distribution of the drug non-invasively. Such probe can also be used to determine the likelihood of the drug reaching the tumor and to what extent.

Note: Drugs that have increased accumulation within the targeted site are likely to be more effective as compared with others. In that respect, Nanoparticle-based drugs have an additional advantage over free drugs with their potential to be multifunctional carriers capable of carrying both therapeutic and diagnostic imaging probes (theranostic) in the same nanocarrier. These multifunctional nanoparticles can serve as theranostic agents and facilitate personalized treatment planning.

  • Imaging can also be used for localization of the tumor to improve the placement of a catheter or external device within tumors to cause cell death through thermal ablation or oxidative stress secondary to reactive oxygen species.

See the example of Vintfolide in The Role of Medical Imaging in Personalized Medicine

vinta

Note: Image guided thermal ablation methods include radiofrequency (RF) ablation, microwave ablation or high intensity focused ultrasound (HIFU). Photodynamic therapy methods using external light devices to activate photosensitizing agents can also be used to treat superficial tumors or deeper tumors when used with endoscopic catheters.

  • Quality control during and post treatment

For example: The use of high intensity focused ultrasound (HIFU) combined with nanoparticle therapeutics: HIFU is applied to improve drug delivery and to trigger drug release from nanoparticles. Gas-bubbles are playing the role of the drug’s nano-carrier. These are used both to increase the drug transport into the cell and as ultrasound-imaging contrast material. The ultrasound is also used for processes of drug-release and ablation.

 HIFU

Additional example; Multifunctional nanoparticles for tracking CED (convection enhanced delivery)  distribution within tumors: Nanoparticle that could serve as a carrier not only for the therapeutic radionuclides but simultaneously also for a therapeutic drug and 4 different types of imaging contrast agents including an MRI contrast agent, PET and SPECT nuclear diagnostic imaging agents and optical contrast agents as shown below. The ability to perform multiple types of imaging on the same nanoparticles will allow studies investigating the distribution and retention of nanoparticles initially in vivo using non-invasive imaging and later at the histological level using optical imaging.

 multi

Conclusions

Image-guided radiotherapeutic nanoparticles have significant potential for solid tumor cancer therapy. The current success of this therapy in animals is most likely due to the improved accumulation, retention and dispersion of nanoparticles within solid tumor following image-guided therapies as well as the micro-field of the β-particle which reduces the requirement of perfectly homogeneous tumor coverage. It is also possible that the intratumoral distribution of nanoparticles may benefit from their uptake by intratumoral macrophages although more research is required to determine the importance of this aspect of intratumoral radionuclide nanoparticle therapy. This new approach to cancer therapy is a fertile ground for many new technological developments as well as for new understandings in the basic biology of cancer therapy. The clinical success of this approach will depend on progress in many areas of interdisciplinary research including imaging technology, nanoparticle technology, computer and robot assisted image-guided application of therapies, radiation physics and oncology. Close collaboration of a wide variety of scientists and physicians including chemists, nanotechnologists, drug delivery experts, radiation physicists, robotics and software experts, toxicologists, surgeons, imaging physicians, and oncologists will best facilitate the implementation of this novel approach to the treatment of cancer in the clinical environment. Image-guided nanoparticle therapies including those with β-emission radionuclide nanoparticles have excellent promise to significantly impact clinical cancer therapy and advance the field of drug delivery.

This is a posting of Relman’s just published review of the new publication  by Elizabeth H. Bradley and Lauren A. Taylor, in the prestigious Public Affairs (AUGUST 14, 2014 ISSUE)

The American Health Care Paradox: Why Spending More Is Getting Us Less

The US spends much more per person on medical care than any other country. And yet,

  • by commonly accepted measures of the quality of its national health system, it ranks only in the middle of the other advanced countries

belonging to the Organization for Economic Cooperation and Development (OECD).

Elizabeth Bradley and Lauren Taylor argue that

  • this “American health care paradox” is resolved when expenditures on other social services that undoubtedly contribute to improved national and personal health are taken into account.

These expenditures include support for such services as housing, education, maternal and child care, disease prevention, nutrition, environmental safety, and unemployment benefits. They also involve subsidies for the very poor, the disabled, and the elderly.

  • The US spends a much smaller percentage of its GDP on these programs than other OECD countries. Thus,

when these expenditures are added to what is spent for medical care, the total, expressed as a percentage of GDP, places our country in the middle of the other OECD countries.

That is consistent with the ranking of our health care system, and so the authors claim

  • the “paradox” is resolved.

To increase the quality of our health care system to the level now achieved by France, Germany, Switzerland, and Sweden,

  1. we would need not only to expand our investment in other social services, but also
  2. to practice what Bradley and Taylor call “a more holistic approach” to the medical care of each patient.

That means more attention to preventing illness and to modifying patients’ behavior in ways that promote health.

Their argument has intuitive appeal, made even stronger by the warm endorsement given by Dr. Harvey Fineberg, outgoing president of the Institute of Medicine (IOM) of the National Academy of Sciences, in the foreword he has written for the book, and by recent reports from committees of the IOM. It is generally agreed that

  • poor and disadvantaged populations, such as teenaged single mothers and their children, or
  • unemployed, uneducated, and ill-housed minorities,

suffer relatively poor health.

So it might seem entirely reasonable to conclude with the authors

  • that the answer to what ails our national health system lies in paying more attention to
  • social welfare programs, preventive measures, and education.

Relman dissatisfied:

Their argument is made more attractive by their clear prose and by their many helpful descriptions and historical explanations of US health care policy. Nevertheless, it does not persuade me, and
I don’t believe it will satisfy many critics who look closely at the issues.

In the first place, Bradley and Taylor pay insufficient attention to the great value Americans place on

  • the immediate diagnosis and treatment of personal illnesses and injuries, as compared with
  • public measures to enhance national health such as disease prevention and nutrition.

In the US, prompt medical care is given

  • far greater priority than improved public health, and
  • it commands much greater resources.

Research on personal medical care is also given a high priority, but  (political reality)

  • new large investments in social welfare programs are not a legislative or political necessity now or in the foreseeable future,
  • so long as conservative Republican opposition to governmental spending of this sort persists.

Moreover, the long-range economic benefits of social welfare and preventive measures are generally misunderstood. For example,

  • prevention of heart attacks in early life through exercise, better diet, and elimination of smoking would extend life into later decades.

That is certainly a desirable goal, but then the multiple

  • incurable disabilities of old age and the need for long-term care after retirement begin to increase total health costs.

Second, the evidence presented by Bradley and Taylor to support their claim of resolving the American health care “paradox” is not as strong as their rhetoric implies. This is well illustrated by their Figure 1.3, which shows

  • aggregate health care and social welfare spending in OECD countries for 2007, and

is supposed to demonstrate that when all costs are considered,

  • the US is no longer as inferior to European countries as many have claimed.

The figure shows that American total expenditures place it just about

  • in the middle of all the countries shown, in accord with the quality of its health care system.

Nevertheless, while total expenditures on health and social welfare in France, Sweden, Switzerland, and Germany exceed those in the US (which would be expected given their generally superior health systems), the figure shows

  • total expenditures for Canada, New Zealand, and Australia to be well below those in the US, even though
  • these countries are widely acknowledged to have better health systems than the US.
  • Similarly, total expenditures in Norway are roughly equal to those in the US, although the Norwegian national health system is generally recognized to be of much higher quality.

Their Table 4.1 (see below) also illustrates this lack of congruence between health care outcomes such as

  • infant mortality and life expectancy in selected countries and
  • their ranking in total expenditures (as shown in Figure 1.3).

In short, total expenditures (social welfare plus medical care) do not seem to be as consistently related to health outcomes as Bradley and Taylor would have us believe. But they are certainly correct in arguing that in general, more attention to welfare programs would improve the quality of life in the US.

American Health Care Paradox

American Health Care Paradox

My final reason for skepticism is the authors’ dependence on personal interviews with

  • a selected and limited number of sources for much of their original data on attitudes about health care.

Bradley, the senior author, is a professor of public health at Yale; Taylor was trained in public health and medical ethics. They would therefore be expected to use

  • the methods of descriptive social science in developing their arguments.

They state that they conducted interviews with “more than eighty health and social policy experts, researchers, practitioners, and consumers.” Anyone who has been involved in such interviews knows how variably the results can be interpreted. Bradley and Taylor were commendably diligent in recording and transcribing their interviews, but

  1. they took a relatively small sample, and
  2. much of it was limited to Scandinavian countries,
  3. which are very different from the US, for example
  • in their levels of taxation and their guarantees of medical care and public welfare generally.

As a result, the reader can never be quite sure how comprehensive and balanced a picture this book presents of the American health system, when compared with other OECD countries.

Nevertheless, it is hard to deny two basic and fairly obvious points the authors want to make.

First, inadequate social services in the US contribute to our poor national health.

Second, adding welfare expenditures to those of medical care does help to some extent to resolve the American “paradox” of high medical expenditures and relatively poor health outcomes. But the resolution

  • is not as complete or convincing as claimed, and
  • there is no evidence that expanding welfare programs,

as Bradley and Taylor argue,

  • would more effectively improve national health than directly reforming the payment and organization of medical services.

In fact, the evidence suggests the contrary. The US currently

  1. wastes vastly more resources on a dysfunctional medical care system than it would ever consider spending on social welfare, so
  2. the likelihood of bettering national health through major expansion of welfare programs is remote.

As difficult as it may be, trying to reform the medical system is a better bet;

  • this would free up resources that could be used to improve other social services.

In addition, most Americans will inevitably become ill or injured at some time in their lives, no matter how adequate the US social services, and for them at that time,

  • a good medical care system is essential. Therefore, it makes sense to consider

how reforming the payment and organization of medical care could reduce the heavy burden of

  • unnecessary waste, fraud, and bureaucratic overhead on our medical care system.

This looks like the best way to begin to resolve this book’s “paradox.”

There is widespread and growing recognition that the best way of improving the delivery of medical service and reducing its costs would be

  • a shift away from fee-for-service payment for medical care after it is received
  • to prepayment for comprehensive care.

The Affordable Care Act (ACA) attempts to move in this direction by establishing “accountable care organizations” that are paid

  1. small bonuses for bettering the treatment of Medicare patients (as defined by government guidelines). However,
  2. these organizations work mainly through private insurance plans, which, despite these intentions,
  3. still pay for the more expensive special procedures and services by fee-for-service.

The ACA is therefore not likely to control national health expenditures in the long term. Government actuaries and budget officers

  • predict that these expenditures will continue to rise at an unsustainable rate unless there is major reform.

To achieve better quality at lower costs, I believe we will have to progress beyond the ACA, and

  • the needed reforms will require more participation by the medical profession.

Physicians will have to join medical groups that accept a single payment for comprehensive care and

  • are willing to be paid mainly by salaries rather than the fees they bill and collect.

Although insurance companies will lobby hard to maintain their power, such a system does not need private insurance plans; it would be much better without them. Vast overhead expenditures would be saved if payment were to come from a single tax-supported agency. That’s why single-payer plans are getting increasing attention these days.

Recent changes in the medical care system have created forces that

  • both favor and inhibit the development of a single-payer arrangement.

Physicians who would formerly have started practicing solo or in small partnerships are rapidly becoming employees of large groups

  • in order to avoid the daunting economic risks of managing their own practices. Unfortunately,
  • most of these large groups are owned by hospitals that are primarily interested in furthering their own financial goals.

They use their physician employees to generate

  • more admissions and greater use of hospital-based procedures.

They want to defend the status quo and their own income, rather than press for reform.

An awakening interest in political affairs and a recent trend toward a preference for Democratic political candidates suggest that

  • the medical profession may soon wish to turn national health policy in a different direction.
    (this is a period of transition between generations)

No large-scale health reform is likely without broad support by physicians, so

  • their political awakening may be the most important factor in bringing about major change.

A united profession could influence the views of its patients, and this in turn could

  • influence legislators even more than the money of an army of lobbyists.
    (army of lobbyists is supported by an exhorbitant wealth disproportion unknown in history, or at least since reconstruction)

Legislators need votes most of all, and patients are the voters they need.
(assumes that patients are a homogeneous group; and thee is no difference between rural and municipalities)

Another recent change that may favor the arrival of single-payer health care is

  • the rapid increase in the number of women in active medical practice.

They will soon equal or outnumber men. Women physicians seem to be more interested in the

  • social services that are available in multispecialty medical group practices,
  • among them adequate child care and parental leaves.
  • They want to share practice responsibilities, and
  • they tend to have more liberal political views than most men.

This major demographic shift in the physician population, as well as its political movement toward more progressive policies, might put the profession in the forefront of health reform instead of the sidelines where it has usually been.

Without leadership by physicians, it is unlikely that we will see any major change in the system for payment and organization of medical care within the next decade or two. And

  1. without such change, the future of the American health system is bleak;
  2. either market forces or intrusive government regulations (or both)
  3. will control how physicians practice their profession.

Financial responsibility for health care coverage will increasingly fall on individuals, because

  • ‘neither government nor business employers will be able to afford the rising costs.

The greatest opportunities for reducing unnecessary costs and improving the quality of the American health system are to be found in

  • reforming the payment and organization of medical care
  • rather than in expanding social welfare programs.

Although these programs are of enormous importance for many reasons not only related to health, and well worth expanding, they cannot substitute for improving the effectiveness and efficiency of medical care for the sick and injured. That is where we are likely to see the most hopeful future development.

Epicrisis:

In my reading of Arnold Relman, I find that there is validity and unrealistic assumptions in his criticism.  It will take a generational change in the profession, which is currently avolving and making some of the changes he notes.

1. There is at least two generations of physicians who entered the profession in the post WWII era, when the Flexner model was in full force, and exemplified by William Osler, the Oslerian model..

Over a century ago, the Quaker merchant Johns Hopkins did more than provide in his will for the construction of a university, a hospital and a medical school.  He provided a vision of a unique university-based health center, one with a vital mission: to create a learning, training and caring environment where the quest for new knowledge would continuously yield more effective and compassionate care for all. Today, after a century of progress that even its founder could not have envisioned, the quest for new knowledge leading to better health care remains the defining mission of Johns Hopkins Medicine.

The original faculty of The Johns Hopkins University School of Medicine, including such pioneers of modern medicine as William H. Welch, William S. Halsted, William Osler and Howard A. Kelly, created a revolutionary new medical curriculum that integrated a rigorous program of basic science education with intensive clinical mentoring. With the opening of The Johns Hopkins Hospital in 1889, followed four years later by the School of Medicine, these founding physicians ushered in a new era in medical education marked by rigid entrance requirements for students, a vastly upgraded curriculum with emphasis on the scientific method, the incorporation of bedside teaching and laboratory research as part of the instruction, and integration of the School of Medicine with the Hospital through joint appointments. 

Notable faculty have included:  John Jacob Abel – Pharmacologist, John Shaw Billings – Civil War surgeon, pioneering leader in hygiene, Alfred Blalock – Developed field of cardiac surgery, Max Brödel – Acclaimed medical illustrator, William R. Brody – Radiologist, President of the Salk Institute, former President of Johns Hopkins University, Ben Carson – Pediatric Neurosurgeon, awarded the Presidential Medal of Freedom, Denton Cooley – Renowned Cardiovascular surgeon, Harvey Cushing – Father of modern neurosurgery, Catherine Clarke Fenselau – Biochemist and mass spectrometrist,  William Halsted – Father of modern surgery, Leo Kanner – Father of child psychiatry, Albert L. Lehninger – Biochemist, Victor McKusick – Developed field of medical genetics, William Osler – Father of modern medicine, Wilder Penfield – Pioneer of epilepsy neurosurgery; developed the cortical homunculus, Peter Pronovost – Anesthesiologst, MacArthur Fellow, Julie A. Freischlag, M.D., the director of the Department of Surgery

2. The large inroads in genetics, genomics and the Human Genome Project attests to the incredible growth in the knowledge base required from which physicians make decisions.  But despite the huge competition for entry, a shortage of primary care physicians, and a brain drain for less developed countries, the multicultural profession has had to adjust to a multicultural society into which it has to be integrated.  As much as a half century ago, candidates competed for entry on the basis of correlation with their undergraduate performance in organic chemistry.

3.  A half century ago, the poor could obtain emergency room care as a primary root of admission, which was likely late in the progression of the illness. This was not then, and is not now an acceptable system.

4. When Medicare came in, physicians accepted it as a reliable source for patients.  The same had to be true for hospitals.

5. Managed care began with the building of the Golden Gate Bridge, finished early, and supported by physicians employed by Henry Kaiser. This became a model taken seriously by Eastman Kodak and IBM.

6. It appears be be difficult to predict what will be in place a decade from now.  The Republican party is in default mode, and the Supreme Court has appointments that have not earned a lifetime appointment.

7.  I can’t see how the reorganizing of medicine, even with NPs and PAs can deal with the healthcare burden without attending to..

  • children in broken families
  • a substantial population in prison confinement
  • dealing with white collar corruption
  • supporting a minimum standard of living
  • an improvement in education at a very young age (with parental involvement)
  • a population that is more than 70% literate

8. There is a young physician population that has a dream and life style that is larger than the ALL MEDICINE and early to rise, late to bed than I have seen for so many years, and compassion has become important, as we don’t have all the answers, or all of the control.

Why did this occur? The matter of Individual Actions Undermining Trust, The Patent Dilemma and The Value of a Clinical Trials

Reporter and Curator: Larry H. Bernstein, MD, FCAP

 

he large amount of funding tied to continued research and support of postdoctoral fellows leads one to ask how following the money can lead to discredited work in th elite scientific community.

Moreover, the pressure to publish in prestigious journals with high impact factors is a road to academic promotion.  In the last twenty years, it is unusual to find submissions for review with less than 6-8 authors, with the statement that all contributed to the work.  These factors can’t be discounted outright, but it is easy for work to fall through the cracks when a key investigator has over 200 publications and holds tenure in a great research environment.  But that is where we find ourselves today.

There is another issue that comes up, which is also related to the issue of carrying out research, and then protecting the work for commercialization.  It is more complicated in the sense that it is necessary to determine whether there is prior art, and then there is the possibility that after the cost of filing patent and a 6 year delay in obtaining protection, there is as great a cost in bringing the patent to finasl production.

I. Top heart lab comes under fire

Kelly Servick

Science 18 July 2014: Vol. 345 no. 6194 p. 254 DOI: 10.1126/science.345.6194.25

 

In the study of cardiac regeneration, Piero Anversa is among the heavy hitters. His research into the heart’s repair mechanisms helped kick-start the field of cardiac cell therapy (see main story). After more than 4 decades of research and 350 papers, he heads a lab at Harvard Medical School’s Brigham and Women’s Hospital (BWH) in Boston that has more than $6 million in active grant funding from the National Institutes of Health (NIH). He is also an outspoken voice in a field full of disagreement.

So when an ongoing BWH investigation of the lab came to light earlier this year, Anversa’s colleagues were transfixed. “Reactions in the field run the gamut from disbelief to vindication,” says Mark Sussman, a cardiovascular researcher at San Diego State University in California who has collaborated with Anversa. By Sussman’s account, Anversa’s reputation for “pushing the envelope” and “challenging existing dogma” has generated some criticism. Others, however, say that the disputes run deeper—to doubts about a cell therapy his lab has developed and about the group’s scientific integrity. Anversa told Science he was unable to comment during the investigation.

“People are talking about this all the time—at every scientific meeting I go to,” says Charles Murry, a cardiovascular pathologist at the University of Washington, Seattle. “It’s of grave concern to people in the field, but it’s been frustrating,” because no information is available about BWH’s investigation. BWH would not comment for this article, other than to say that it addresses concerns about its researchers confidentially.

In April, however, the journal Circulation agreed to Harvard’s request to retract a 2012 paper on which Anversa is a corresponding author, citing “compromised” data. The Lancet also issued an “Expression of Concern” about a 2011 paper reporting results from a clinical trial, known as SCIPIO, on which Anversa collaborated. According to a notice from the journal, two supplemental figures are at issue.

For some, Anversa’s status has earned him the benefit of the doubt. “Obviously, this is very disconcerting,” says Timothy Kamp, a cardiologist at the University of Wisconsin, Madison, but “I would be surprised if it was an implication of a whole career of research.”

Throughout that career, Anversa has argued that the heart is a prolific, lifelong factory for new muscle cells. Most now accept the view that the adult heart can regenerate muscle, but many have sparred with Anversa over his high estimates for the rate of this turnover, which he maintained in the retracted Circulation paper.

Anversa’s group also pioneered a method of separating cells with potential regenerative abilities from other cardiac tissue based on the presence of a protein called c-kit. After publishing evidence that these cardiac c-kit+cells spur new muscle growth in rodent hearts, the group collaborated in the SCIPIO trial to inject them into patients with heart failure. In The Lancet, the scientists reported that the therapy was safe and showed modest ability to strengthen the heart—evidence that many found intriguing and provocative. Roberto Bolli, the cardiologist whose group at the University of Louisville in Kentucky ran the SCIPIO trial, plans to test c-kit+ cells in further clinical trials as part of the NIH-funded Cardiovascular Cell Therapy Research Network.

But others have been unable to reproduce the dramatic effects Anversa saw in animals, and some have questioned whether these cells really have stem cell–like properties. In May, a group led by Jeffery Molkentin, a molecular biologist at Cincinnati Children’s Hospital Medical Center in Ohio, published a paper in Nature tracing the genetic lineage of c-kit+ cells that reside in the heart. He concluded that although they did make new muscle cells, the number is “astonishingly low” and likely not enough to contribute to the repair of damaged hearts. Still, Molkentin says that he “believe[s] in their therapeutic potential” and that he and Anversa have discussed collaborating.

Now, an anonymous blogger claims that problems in the Anversa lab go beyond controversial findings. In a letter published on the blog Retraction Watch on 30 May, a former research fellow in the Anversa lab described a lab culture focused on protecting the c-kit+ cell hypothesis: “[A]ll data that did not point to the ‘truth’ of the hypothesis were considered wrong,” the person wrote. But another former lab member offers a different perspective. “I had a great experience,” says Federica Limana, a cardiovascular disease researcher at IRCCS San Raffaele Pisana in Rome who spent 2 years of her Ph.D. work with the group in 1999 and 2000, as it was beginning to investigate c-kit+ cells. “In that period, there was no such pressure” to produce any particular result, she says.

Accusations about the lab’s integrity, combined with continued silence from BWH, are deeply troubling for scientists who have staked their research on theories that Anversa helped pioneer. Some have criticized BWH for requesting retractions in the midst of an investigation. “Scientific reputations and careers hang in the balance,” Sussman says, “so everyone should wait until all facts are clearly and fully disclosed.”

 

II.  Trolling Along: Recent Commotion About Patent Trolls

July 17, 2014

PriceWaterhouseCoopers recently released a study about 2014 Patent Litigation. PwC’s ultimate conclusion was that case volume increased vastly and damages continue a general decline, but what’s making headlines everywhere is that “patent trolls” now account for 67% of all new patent lawsuits (see, e.g., Washington Post and Fast Company).

Surprisingly, looking at PwC’s study, the word “troll” is not to be found. So, with regard to patent trolls, what does this study really mean for companies, patent owners and casual onlookers?

First of all, who are these trolls?

“Patent Troll” is a label applied to patent owners who do not make or manufacture a product, or offer a service. Patent trolls live (and die) by suing others for allegedly practicing an invention that is claimed by their patents.

The politically correct term is Non-practicing Entity (NPE). PwC solely uses the term NPE, which it defines as an entity that does not have the capability to design, manufacture, or distribute products with features protected by the patent.

So, what’s so bad about them?

The common impression of an NPEs is a business venture looking to collect and monetize assets (i.e., patents). In the most basic strategy, an NPE typically buys patents with broad claims that cover a wide variety of technologies and markets, and then sues a large group of alleged patent infringers in the hope to collect a licensing royalty or a settlement. NPEs typically don’t want to spend money on a trial unless they have to, and one tactic uses settlements with smaller businesses to build a “war chest” for potential suits with larger companies.

NPEs initiating a lawsuit can be viewed positively, such as a just defense of the lowly inventor who sold his patent to someone (with deeper pockets) who could fund the litigation to protect the inventor’s hard work against a mega-conglomerate who ripped off his idea.

Or NPE litigation can be seen negatively, such as an attorney’s demand letter on behalf of an anonymous shell corporation to shake down dozens of five-figure settlements from all the local small businesses that have ever used a fax machine.

NPEs can waste a company’s valuable time and resources with lawsuits, yet also bring value to their patent portfolios by energizing a patent sales and licensing market. There are unscrupulous NPEs, but it’s hardly the black and white situation that some media outlets are depicting.

What did PwC say about trolls?

Well, the PwC study looked at the success rates and awards of patent litigation decisions. One conclusion is that damages awards for NPEs averaged more than triple those for practicing entities over the last four years. We’ll come back to this statistic.

Another key observation is that NPEs have been successful 25% of the time overall, versus 35% for practicing entities. This makes sense because of the burden of proof the NPEs carry as a plaintiff at trial and the relative lack of success for NPEs at summary judgment. However, PwC’s report states that both types of entities win about two-thirds of their trials.

But what about this “67% of all patent trials are initiated by trolls” discussion?

The 67% number comes from the RPX Corporation’s litigation report (produced January 2014) that quantified the percentage of NPE cases filed in 2013 as 67%, compared to 64% in 2012, 47% in 2011, 30% in 2010 and 28% in 2009.

PwC refers to the RPX statistics to accentuate that this new study indicates that only 20% ofdecisions in 2013 involved NPE-filed cases, so the general conclusion would be that NPE cases tend to settle or be dismissed prior to a court’s decision. Admittedly, this is indicative of the prevalent “spray and pray” strategy where NPEs prefer to collect many settlement checks from several “targets” and avoid the courtroom.

In this study, who else is an NPE?

If someone were looking to dramatize the role of “trolls,” the name can be thrown around liberally (and hurtfully) to anyone who owns and asserts a patent without offering a product or a service. For instance, colleges and universities fall under the NPE umbrella as their research and development often ends with a series of published papers rather than a marketable product on an assembly line.

In fact, PwC distinguishes universities and non-profits from companies and individuals within their NPE analysis, with only about 5% of the NPE cases from 1995 to 2013 being attributed to universities and non-profits. Almost 50% of the NPE cases are attributed to an “individual,” who could be the listed inventor for the patent or a third-party assignee.

The word “troll” is obviously a derogatory term used to connote greed and hiding (under a bridge), but the term has adopted a newer, meme-like status as trolls are currently depicted as lacking any contribution to society and merely living off of others’ misfortunes and fears. [Three Billy Goats Gruff]. This is not always the truth with NPEs (e.g., universities).

No one wants to be called a troll—especially in front of a jury—so we’ve even recently seen courts bar defendants from referring to NPEs as such colorful terms as a “corporate shell,” “bounty hunter,” “privateer,” or someone “playing the lawsuit lottery.” [Judge Koh Bans Use Of Term ” Patent Troll” In Apple Jury Trial]

Regardless of the portrayal of an NPE, most people in the patent world distinguish the “trolls” by the strength of the patent, merits of the alleged infringement and their behavior upon notification. Often these are expressed as “frivolity” of the case and “gamesmanship” of the attorneys. Courts are able to punish plaintiffs who bring frivolous claims against a party and state bar associations are tasked with monitoring the ethics of attorneys. The USPTO is tasked with working to strengthen the quality of patents.

What’s the take-away from this study regarding NPEs?

The study focuses on patent litigation that produced a decision, therefore the most important and relevant conclusion is that, over the last four years, average damages awards for NPEs are more than triple the damages for practicing entities. Everything else in these articles, such as the initiation of litigation by NPEs, settlement percentages, and the general behavior of patent trolls is pure inference beyond the scope of the study.

This may sound sympathetic to trolls, but keep in mind that the study highlights that NPEs have more than triple the damages on average compared to practicing entities and it is meant to shock the reader a bit. One explanation for this is that NPEs are in the best position to choose the patents they want to assert and choose the targets they wish to sue—especially when the NPE is willing to ride that patent all the way to the end of a long, expensive trial. Sometimes settling is not an option. Chart 2b indicates that the disparity in the damages awarded to NPEs relative to practicing entities has always been big (since 2000), but perhaps going from two-fold from 2000 – 2009 to three times as much in the past 4 years indicates that NPEs are improving at finding patents and/or picking battles to take all the way to a court decision. More than anything, this seems to reflect the growth in the concept of patents as a business asset.

The PwC report is chock full of interesting patterns and trends of litigation results, so it’s a shame that the 67% number makes the headlines—far more interesting are the charts comparing success rates by 4-year periods (Chart 6b) or success rates for NPEs and practicing entities in front of a jury verusin front of a bench (Chart 6c), as well as other tables that reveal statistics for specific districts of the federal courts. Even the stats that look at the success rates of each type of NPE are telling because the reader sees that universities and non-profits have a higher success rate than non-practicing companies or individuals.

What do we do about the trolls?

The White House has recently called for Congress to do something about the trolls as horror stories of scams and shake-downs are shared. A bill was gaining momentum in the Senate, when Senator Leahy took it off the agenda in early July. That bill had miraculously passed 325-91 in the House and President Obama was willing to sign it if the Senate were to pass it. The bill was opposed by trial attorneys, universities, and bio-pharmaceutical businesses who felt as though the law would severely inhibit everyone’s access to the courts in order to hinder just the trolls. Regardless, most people think that the sitting Congressmen merely wanted a “win” prior to the mid-term elections and that patent reform is unlikely to reappear until next term.

In the meantime, the Supreme Court has recently reiterated rules concerning attorney fee-shifting on frivolous patent cases, as well as clarifying the validity of software patents. Time will tell if these changes have any effects on the damages awards that PwC’s study examined or even if they cause a chilling of the number of patent lawsuit filings.

Furthermore, new ways to challenge the validity of asserted patents have been initiated via the America Invents Act. For example, the Inter Partes Review (IPR) has yielded frightening preliminary statistics as to slowing, if not killing, patents that have been asserted in a suit. While these administrative trials are not cheap, many view these new tools at the Patent Trial and Appeals Board as anti-troll measures. It will be interesting to watch how the USPTO implements these procedures in the near future, especially while former Google counsel, Acting Director Michelle K. Lee, oversees the office.

In the private sector, Silicon Valley has recently seen a handful of tech companies come together as the License on Transfer Network, a group hoping to disarm the “Patent Assertion Entities.” Joining the LOT Network comes via an agreement that creates a license for use of a patent by anyone in the LOT network once that patent is sold. The thought is that the NPEs who consider purchasing patents from companies in the LOT Network will have fewer companies to sue since the license to the other active LOT participants will have triggered upon the transfer and, thus, the NPE will not be as inclined to “troll.” For instance, if a member-company such as Google were to sell a patent to a non-member company and an NPE bought that patent, the NPE would not be able to sue any members of the LOT Network with that patent.

Other notes

NPEs are only as evil as the people who run them—that being said, there are plenty of horror stories of small businesses receiving phantom demand letters that threaten a patent infringement suit without identifying themselves or the patent. This is an out-and-out scam and a plague on society that results in wasted time and resource, and inevitably higher prices on the consumer end.

It is a sin and a shame that patent rights can be misused in scams and shake-downs of businesses around us, but there is a reason that U.S. courts are so often used to defend patent rights. The PwC study, at minimum, reflects the high stakes of the patent market and perhaps the fragility. Nevertheless, merely monitoring the courts may not keep the trolls at bay.

I’d love to hear your thoughts.

III. Large-scale analysis finds majority of clinical trials don’t provide meaningful evidence

Ineffective Treatments, Medical Ethics • Tags: Center for Drug Evaluation and Research, Clinical trial, CTTI, Duke University Hospital, FDA, Food and Drug Administration, National Institutes of Health, United States National Library of Medicine

04 May 2012

DURHAM, N.C.— The largest comprehensive analysis of ClinicalTrials.gov finds that clinical trials are falling short of producing high-quality evidence needed to guide medical decision-making. The analysis, published today in JAMA, found the majority of clinical trials is small, and there are significant differences among methodical approaches, including randomizing, blinding and the use of data monitoring committees.

“Our analysis raises questions about the best methods for generating evidence, as well as the capacity of the clinical trials enterprise to supply sufficient amounts of high quality evidence to ensure confidence in guideline recommendations,” said Robert Califf, M.D., first author of the paper, vice chancellor for clinical research at Duke University Medical Center, and director of the Duke Translational Medicine Institute.

The analysis was conducted by the Clinical Trials Transformation Initiative (CTTI), a public private partnership founded by the Food and Drug Administration (FDA) and Duke. It extends the usability of the data in ClinicalTrials.gov for research by placing the data through September 27, 2010 into a database structured to facilitate aggregate analysis. This publically accessible database facilitates the assessment of the clinical trials enterprise in a more comprehensive manner than ever before and enables the identification of trends by study type.

 

The National Library of Medicine (NLM), a part of the National Institutes of Health, developed and manages ClinicalTrials.gov. This site maintains a registry of past, current, and planned clinical research studies.

“Since 2007, the Food and Drug Administration Amendment Act has required registration of clinical trials, and the expanded scope and rigor of trial registration policies internationally is producing more complete data from around the world,” stated Deborah Zarin, MD, director, ClinicalTrials.gov, and assistant director for clinical research projects, NLM. “We have amassed over 120,000 registered clinical trials. This rich repository of data has a lot to say about the national and international research portfolio.”

This CTTI project was a collaborative effort by informaticians, statisticians and project managers from NLM, FDA and Duke. CTTI comprises more than 60 member organizations with the goal of identifying practices that will improve the quality and efficiency of clinical trials.

“Since the ClinicalTrials.gov registry contains studies sponsored by multiple entities, including government, industry, foundations and universities, CTTI leaders recognized that it might be a valuable source for benchmarking the state of the clinical trials enterprise,” stated Judith Kramer, MD, executive director of CTTI.

The project goal was to produce an easily accessible database incorporating advances in informatics to permit a detailed characterization of the body of clinical research and facilitate analysis of groups of studies by therapeutic areas, by type of sponsor, by number of participants and by many other parameters.

“Analysis of the entire portfolio will enable the many entities in the clinical trials enterprise to examine their practices in comparison with others,” says Califf. “For example, 96% of clinical trials have ≤1000 participants, and 62% have ≤ 100. While there are many excellent small clinical trials, these studies will not be able to inform patients, doctors and consumers about the choices they must make to prevent and treat disease.”

The analysis showed heterogeneity in median trial size, with cardiovascular trials tending to be twice as large as those in oncology and trials in mental health falling in the middle. It also showed major differences in the use of randomization, blinding, and data monitoring committees, critical issues often used to judge the quality of evidence for medical decisions in clinical practice guidelines and systematic overviews.

“These results reinforce the importance of exploration, analysis and inspection of our clinical trials enterprise,” said Rachel Behrman Sherman, MD, associate director for the Office of Medical Policy at the FDA’s Center for Drug Evaluation and Research. “Generation of this evidence will contribute to our understanding of the number of studies in different phases of research, the therapeutic areas, and ways we can improve data collection about clinical trials, eventually improving the quality of clinical trials.”

IV.  Lawmakers urge CMS to extend MU hardship exemption for pathologists

 

Eighty-nine members of Congress have asked the Centers for Medicare & Medicaid Services to give pathologists a break and extend the hardship exemption they currently enjoy for all of Stage 3 of the Meaningful Use program.In the letter–dated July 10 and addressed to CMS Administrator Marilyn Tavenner–the lawmakers point out that CMS had recognized in its 2012 final rule implementing Stage 2 of the program that it was difficult for pathologists to meet the Meaningful Use requirements and granted a one year exception for 2015, the first year that penalties will be imposed. They now are asking that the exception be expanded to include the full five-year maximum allowed under the American Recovery and Reinvestment Act.

“Pathologists have limited direct contact with patients and do not operate in EHRs,” the letter states. “Instead, pathologists use sophisticated computerized laboratory information systems (LISs) to support the work of analyzing patient specimens and generating test results. These LISs exchange laboratory and pathology data with EHRs.”

Interestingly, the lawmakers’ exemption request is only on behalf of pathologists, even though CMS had granted the one-year hardship exception to pathologists, radiologists and anesthesiologists.

Rep. Tom Price (R-Ga.), one of the members spearheading the letter, had also introduced a bill (H.R. 1309) in March 2013 that would exclude pathologists from the incentives and penalties of the Meaningful Use program. The bill, which has 31 cosponsors, is currently sitting in committee. That bill also does not include relief for radiologists or anesthesiologists.

CMS has provided some flexibility about the hardship exceptions in the past, most recently by allowing providers to apply for one due to EHR vendor delays in upgrading to Stage 2 of the program.

However, CMS also noted in the 2012 rule granting the one-year exception that it was granting the exception in large part because of the then-current lack of health information exchange and that “physicians in these three specialties should not expect that this exception will continue indefinitely, nor should they expect that we will grant the exception for the full 5-year period permitted by statute.”

http://pharmaceuticalintelligence/7/8/2014/Proteins and cellular adaptation to stress

There are two recent articles that are, if not interesting, possibly important in the direction of cellular regulation, adaptation, and decline.  One deals with apoptosis, or cell death, which is synchronized with recovery of membrane and protein breakdown for reuse in synthesis and maintenance.  The other is a new perspective to Alzhemier’s Disease, for which there is no effective pharmacotherapy. In both cases, the stresses of the cell are critical to the responce to the environment.  This is not just about the classical transcriptomics story. This is a perfect followup to the just posted research on the regulatory role of a small RNA that is related to, but distinct from silencing RNA, and also the revelations about lncRNA.

Protein Helps Cells Adapt—or Die

Scientists show how cell stress both prevents and promotes cell suicide in a study that’s equally divisive.

By Ruth Williams | July 3, 2014

A cellular stress pathway called the unfolded-protein-response (UPR) both activates and degrades death receptor 5 protein (DR5), which can promote or prevent cell suicide, according to a paper published in Science today (July 3). The theory is that initial stress blocks cell suicide, or apoptosis, to give the cell a chance to adapt, but that if the stress persists, it eventually triggers apoptosis.

“This work has made the most beautiful simplification of all this big complex mess. Basically, they identified and pinpointed the specific protein involved in the switching decision and explain how the decision is made,” said Alexei Korennykh, a professor of molecular biology at Princeton University, who was not involved in the work.

But Randal Kaufman of the Sanford-Burnham Medical Research Institute in La Jolla, California, was not impressed. He questioned the physiological relevance of the experiments supporting the authors’ main conclusions about this key cellular process.

Protein folding in a cell takes place largely in the endoplasmic reticulum (ER), but if the process goes awry, unfolded proteins accumulate, stressing the ER. This triggers the UPR, which shuts down translation, degrades unfolded proteins, and increases production of protein-folding machinery. If ER stress is not resolved, however, the UPR can also induce apoptosis.

Two main factors control the UPR—IRE1a and PERK. IRE1a promotes cell survival by activating the transcription factor XBP1, which drives expression of cell-survival genes. PERK, on the other hand, activates a transcription factor called CHOP, which in turn drives expression of the proapoptotic factor DR5.

Peter Walter of the University of California, San Francisco, and his colleagues have now confirmed that CHOP activates DR5, showing that it is a cell-autonomous process. But they have also found that IRE1a suppresses DR5, directly degrading its mRNA through a process called regulated IRE1a-dependent degradation (RIDD). Inhibition of IRE1a in a human cancer cell line undergoing ER stress both prevented DR5 mRNA decay and increased apoptosis.

However, in an e-mail to The Scientist, Kaufman expressed concern that “the significance of RIDD has not been demonstrated in a physiologically-relevant context.”

Walter insisted that the evidence for RIDD’s existence is “crystal clear.” His only concession was that “the effects aren’t 100 percent,” he said, because “RIDD degrades mRNA by a few-fold,” making it difficult to measure.

This RIDD debate aside, the researchers have also sparked a rumpus with their finding that IRE1a expression switches off just 24 hours after ER stress initiation, leaving PERK to drive the cell toward apoptosis. “We and others have evidence that suggests another model,” said Scott Oakes, a professor of pathology at the University of California, San Francisco, “which is that both PERK and IRE1a under high stress will send out death signals.”

Whether IRE1a promotes or inhibits apoptosis under extreme stress “is controversial,” said Ira Tabas, a professor at Columbia University in New York City. But it’s essential that scientists figure it out. Cell death from ER stress is a pathological process in many major diseases, Tabas said, and there are IRE1a inhibitors in pharmaceutical development. “It is very important because under high stress you have two different views here,” said Oakes. “One is that you want to keep IRE1a on, the other is that you want to shut it off.”

Because ER stress is central to many diseases, “a lot of people are passionate about it,” said Tabas, explaining the polemic views. “Who’s right? . . . I think it depends on the context in which the experiments are done—one pathway may be important in some settings, and another pathway may be important in different settings,” he suggested. What might help to resolve the issues, he said, will be “in vivo causation studies using actual disease models.”

Researchers will continue to debate. So, said Walter, “we’ll have to see what holds-up five years from now.”

Protein May Hold the Key to Who Gets Alzheimer’s

 

By PAM BELLUCK     MARCH 19, 2014

 

It is one of the big scientific mysteries of Alzheimer’s disease: Why do some people whose brains accumulate the plaques and tangles so strongly associated with Alzheimer’s not develop the disease?

 

Now, a series of studies by Harvard scientists suggests a possible answer, one that could lead to new treatments if confirmed by other research.

 

The memory and thinking problems of Alzheimer’s disease and other dementias, which affect an estimated seven million Americans, may be related to a failure in the brain’s stress response system, the new research suggests. If this system is working well, it can protect the brain from abnormal Alzheimer’s proteins; if it gets derailed, critical areas of the brain start degenerating.

“This is an extremely important study,” said Li-Huei Tsai, director of the Picower Institute for Learning and Memory at the Massachusetts Institute of Technology, who was not involved in the research but wrote a commentary accompanying the study. “This is the first study that is really starting to provide a plausible pathway to explain why some people are more vulnerable to Alzheimer’s than other people.”

The research, published on Wednesday in the journal Nature, focuses on a protein previously thought to act mostly in the brains of developing fetuses. The scientists found that the protein also appears to protect neurons in healthy older people from aging-related stresses. But in people with Alzheimer’s and other dementias, the protein is sharply depleted in key brain regions.

Experts said if other scientists could replicate and expand upon the findings, the role of the protein, called REST, could spur development of new drugs for dementia, which has so far been virtually impossible to treat. But they cautioned that much more needed to be determined, including whether the decline of REST was a cause, or an effect, of brain deterioration, and whether it was specific enough to neurological diseases that it could lead to effective therapies.

“You’re going to see a lot of papers now following up on it,” said Dr. Eric M. Reiman, executive director of the Banner Alzheimer’s Institute in Phoenix, who was not involved in the study. “While it’s a preliminary finding, it raises an avenue that hasn’t been considered before. And if this provides a handle on which to understand normal brain aging, that will be great, too.”

REST, a regulator that switches off certain genes, is primarily known to keep fetal neurons in an immature state until they develop to perform brain functions, said Dr. Bruce A. Yankner, a professor of genetics at Harvard Medical School and the lead author of the new study. By the time babies are born, REST becomes inactive, he said, except in some areas outside the brain like the colon, where it seems to suppress cancer.

While investigating how different genes in the brain change as people age, Dr. Yankner’s team was startled to find that REST was the most active gene regulator in older brains. The researchers have found that this protein, normally active in fetuses, may also protect the neurons in older people.  It is not yet possible to measure the levels of this protein that is a gene regulator called REST, in living people.

“Why should a fetal gene be coming on in an aging brain?” he wondered. He hypothesized that it was because in aging, as in birth, brains encounter great stress, threatening neurons that cannot regenerate if harmed.

His team discovered that REST appears to switch off genes that promote cell death, protecting neurons from normal aging processes like energy decrease, inflammation and oxidative stress.

Analyzing brains from brain banks and dementia studies, the researchers found that brains of young adults ages 20 to 35 contained little REST, while healthy adults between the ages of 73 and 106 had plenty. REST levels grew the older people got, so long as they did not develop dementia, suggesting that REST is related to longevity.

But in people with Alzheimer’s, mild cognitive impairment, frontotemporal dementia and Lewy body dementia, the brain areas affected by these diseases contained much less REST than healthy brains.

This was true only in people who actually had memory and thinking problems. People who remained cognitively healthy, but whose brains had the same accumulation of amyloid plaques and tau tangles as people with Alzheimer’s, had three times more REST than those suffering Alzheimer’s symptoms. About a third of people who have such plaques will not develop Alzheimer’s symptoms, studies show.

REST levels dropped as symptoms worsened, so people with mild cognitive impairment had more REST than Alzheimer’s patients. And only key brain regions were affected. In Alzheimer’s, REST steeply declined in the prefrontal cortex and hippocampus, areas critical to learning, memory and planning. Other areas of the brain not involved in Alzheimer’s showed no REST drop-off.

It is not yet possible to analyze REST levels in the brains of living people, and several Alzheimer’s experts said that fact limited what the new research could prove.

John Hardy, an Alzheimer’s researcher at University College London, cautioned in an email that information from post-mortem brains could not prove that a decline in REST caused dementia because death might produce unrelated damage to brain cells.

To investigate further, the team conducted what both Dr. Tsai and Dr. Reiman called a “tour de force” of research, examining REST in mice, roundworms and cells in the lab.

“We wanted to make sure the story was right,” Dr. Yankner said. “It was difficult to believe at first, to be honest with you.”

Especially persuasive was that mice genetically engineered to lack REST lost neurons as they aged in brain areas afflicted in Alzheimer’s.

Dr. Yankner said REST appeared to work by traveling to a neuron’s nucleus when the brain was stressed. In dementia, though, REST somehow gets diverted, traveling with toxic dementia-related proteins to another part of the neuron where it is eventually destroyed.

Experts said the research, while intriguing, left many unanswered questions. Bradley Wise of the National Institute on Aging’s neuroscience division, which helped finance the studies, said REST’s role needed further clarification. “I don’t think you can really say if it’s a cause of Alzheimer’s or a consequence of Alzheimer’s” yet, he said.

Dr. Samuel E. Gandy, an Alzheimer’s researcher at Mount Sinai Medical Center, wondered if REST figured only in neurodegenerative diseases or in other diseases, too, which could make it difficult to use REST to develop specific treatments or diagnostic tests for dementia.

“My ambivalence is, is this really a way that advances our understanding of the disease or does this just tell us this is even more complicated than we thought?” he said.

Dr. Yankner’s team is looking at REST in other neurological diseases, like Parkinson’s. He also has thoughts about a potential treatment, lithium, which he said appears to stimulate REST function, and is considered relatively safe.

But he and other experts said it was too early. “I would hesitate to start rushing into lithium treatment” unless rigorous studies showed that it could forestall dementia, said Dr. John C. Morris, an Alzheimer’s researcher at Washington University in St. Louis.

Still, Dr. Morris said, the REST research the team conducted so far is “very well done, and certainly helps support this idea that we’ve all tried to understand about why Alzheimer’s is age-associated and why, while amyloid is necessary for the development of Alzheimer’s disease, it certainly is not sufficient.”

He added, “There have to be some other processes and triggers that result in Alzheimer’s.”

 Reason in Hobby Lobby

 

 

Reason #1 SCOTUS Will Regret Hobby Lobby byMan from Wasichustan

After oral arguments in the Hobby Lobby case, I wrote a very misnamed but widely read diary in which I echoed Attorney and Ring of Fire radio host Mike Papantonio’s argument that the SCOTUS would never rule in favor of Hobby Lobby for a really Big Business reason: It pierces the corporate veil.  If Hobby Lobby’s owners can give their Corporation religion, their religion gives Hobby Lobby’s owners–and any other owner, shareholder, officer, whatever–liability for the actions of the corporation.  Mr. Papantonio, who happens to be one of America’s preeminent trial lawyers, sees it as an opportunity to sue owners for the company’s negligence. Some other people, it turns out, agree with his assessment and expand on what it means….

That separation is what legal and business scholars call the “corporate veil,” and it’s fundamental to the entire operation. Now, thanks to the Hobby Lobby case, it’s in question. By letting Hobby Lobby’s owners assert their personal religious rights over an entire corporation, the Supreme Court has poked a major hole in the veil. In other words, if a company is not truly separate from its owners, the owners could be made responsible for its debts and other burdens.  So says Alex Park, writing in Salon today.

“If religious shareholders can do it, why can’t creditors and government regulators pierce the corporate veil in the other direction?” Burt Neuborne, a law professor at New York University, asked in an email. That’s a question raised by 44 other law professors, who filed a friends-of-the-court brief that implored the Court to reject Hobby Lobby’s argument and hold the veil in place. Here’s what they argued: Allowing a corporation, through either shareholder vote or board resolution, to take on and assert the religious beliefs of its shareholders in order to avoid having to comply with a generally-applicable law with a secular purpose is fundamentally at odds with the entire concept of incorporation.

Creating such an unprecedented and idiosyncratic tear in the corporate veil would also carry with it unintended consequences, many of which are not easily foreseen. This is definitely going to complicate things for the religious extremists on the SCOTUS and empire wide as these lawsuits inevitably proliferate.  Putting on the popcorn….now.

George Takei’s blistering response to #HobbyLobby: Could a Muslim Corp impose Sharia Law?

byVyan   THU JUL 03, 2014 AT 09:12 AM PDT “The ruling elevates the rights of a FOR-PROFIT CORPORATION over those of its women employees and opens the door to all manner of claims that a company can refuse services based on its owner’s religion,” Takei wrote.

(O)ne wonders,” he said, “whether the case would have come out differently if a Muslim-run chain business attempted to impose Sharia law on its employees.” “Hobby Lobby is not a church. It’s a business — and a big one at that,” he continued. “Businesses must and should be required to comply with neutrally crafted laws of general applicability.

Your boss should not have a say over your healthcare. Just as Justice Ginsberg and Mr Takei have suggested, the Hyper-Religious are already attempting to capitalize on the SCOTUS new granting of the rights of an individual to a corporate entity. In this decision the SCOTUS Majority opinion claimed that they were not granting the equal legitimacy of such follow on requests, but they’ve kicked open the door. Takei – bless his soul – also pointed out the basic hypocrisy of Hobby Lobby’s business practices in regards to religion.  Noting that… …Hobby Lobby has invested in multiple companies that manufacture abortion drugs and birth control. The company receives most of its merchandise from China, a country where overpopulation has led to mandatory abortions and sterilizations for women who try to have more than one child.

What the battle over birth control is really about     byteacherken

in a 2012 piece at Alternet by Sara Robinson. Conservative bishops and Congressmen are fighting a rear-guard action against one of the most revolutionary changes in human history. Robinson suggests 500 years from now looking back, the three great achievements of the 20th Century are likely to be the invention of the integrated circuit (without which the internet does not exist), the Moon landing (which she thinks will carry the same impact as Magellan’s circumnavigation of the globe), and the mass availability of nearly 100% effective contraception.

 Free Birth Control is Emerging Standard for Women   RICARDO ALONSO-ZALDIVAR, Associated Press       07/07/2014

WASHINGTON (AP) — More than half of privately insured women are getting free birth control under President Barack Obama’s health law, a major coverage shift that’s likely to advance. This week the Supreme Court allowed some employers with religious scruples to opt out, but most companies appear to be going in the opposite direction. Recent data from the IMS Institute document a sharp change during 2013. The share of privately insured women who got their birth control pills without a copayment jumped to 56 percent, from 14 percent in 2012. The law’s requirement that most health plans cover birth control as prevention, at no additional cost to women, took full effect in 2013. The average annual saving for women was $269. “It’s a big number,” said institute director Michael Kleinrock. The institute is the research arm of IMS Health, a Connecticut-based technology company that uses pharmacy records to track prescription drug sales. The core of Obama’s law — taxpayer-subsidized coverage for the uninsured — benefits a relatively small share of Americans. But free preventive care— from flu shots to colonoscopies —is a dividend of sorts for the majority with employer coverage.
