TCT 2015: Abbott’s Absorb meets endpoint in U.S. pivotal trial

One-year data from the Absorb III trial of 2,008 patients showed that the Absorb device was non-inferior to Abbott’s flagship Xience drug-eluting stent. The Absorb device is designed to fully dissolve after delivering its anti-restenosis drug payload, unlike conventional drug-eluting stents what leave behind a metal scaffold.

The trial showed a rate of target lesion failure of 7.8% for the Absorb arm and 6.1% for the Xience arm and no significant difference in rates of cardiac death (0.6% for the Absorb stent and 0.1% for the Xience stent); target vessel myocardial infarction (6.0% and 4.6%, respectively); or ischemia-driven target-lesion revascularization (3.0% and 2.5%, respectively. Device thrombosis occurred in 1.5% of Absorb patients and 0.7% of Xience patients, according to the study, which was also published in the New England Journal of Medicine.

“The Absorb III data shows that there are no statistically significant 1-year differences between Absorb and Xience, which is a major accomplishment given Xience’s strong performance as the current standard of care,” co-principal investigator Dr. Dean Kereiakes of Cincinnati’s Christ Hospital Heart & Vascular Center said in prepared remarks. “Naturally dissolving heart stents are the next revolution in percutaneous coronary intervention, and Absorb is leading the way as an innovative option. Absorb does its job and then restores the vessel to its natural state over time, which cannot be achieved with a permanent drug eluting stent.”

During a press conference discussing the results, Kereiakes cited Absorb’s performance in the context of a 1st-generation device going up against what he called the “gold standard” in Xience.

“The remarkable thing is that a gen-1 device really goes toe to toe [with Xience],” he said. “Longer-term evaluation is ongoing to determine if Absorb improves late outcomes compared with Xience.”

Asked about the value proposition for Absorb versus Xience, Dr. Daniel Simon of Cleveland’s Harrington Heart & Vascular Institute said providers are usually willing to pay a little more for new technologies.

“In medicine, in general, when you have technological iterations and innovations, one tends to pay more,” Simon said, noting that . “Health systems allow for companies to make fair profit, [in order] to have advances in medicine. … The long and the short of it is, we’ll pay a little more for a device that patients are asking for.”

Data from 2 other studies presented today at TCT 2015, Absorb II and Absorb China, also showed that the Absorb device functions similarly to Xience.

“The trial met all its major endpoints, and given all the attributes my opinion is that it should be approvable,” said Dr. Gregg Stone of New York’s Columbia University Medical Center, global chairman of the study. “We’ve got good reason to be very hopeful that the long-term outcomes for patients will be improved with this device compared with a normal metallic drug-eluting stent.

“A lot of patients would much rather have a dissolving stent that returns arteries back to their normal condition,” Stone said. “It will be very good for young patients who will live 30 or 40 years with this decision.”

“Results of the Absorb III pivotal trial show that Absorb is comparable to the best-in-class metallic stent. However, because Absorb leaves nothing behind it may provide significant longterm benefits, such as a restored vessel in a natural state and renewed possibilities for people treated with Absorb,” added Abbott vice president Dr. Charles Simonton in a press release. “At Abbott we will continue to study Absorb in our robust clinical trials to show the long-term benefits of Absorb that differentiate it from permanent, metallic stents.”

Fractional Flow Reserve vs. Angiography in Non-ST-segment Elevation Myocardial Infarction

Reporter: Aviva Lev-Ari, PhD, RN

Disclosures

Eur Heart J. 2015;36(2):100-111. 

Aim

We assessed the management and outcomes of non-ST segment elevation myocardial infarction (NSTEMI) patients randomly assigned to fractional flow reserve (FFR)-guided management or angiography-guided standard care.

Methods and results

We conducted a prospective, multicentre, parallel group, 1 : 1 randomized, controlled trial in 350 NSTEMI patients with ≥1 coronary stenosis ≥30% of the lumen diameter assessed visually (threshold for FFR measurement) (NCT01764334).

Enrolment took place in six UK hospitals from October 2011 to May 2013. Fractional flow reserve was disclosed to the operator in the FFR-guided group (n 1/4 176). Fractional flowreserve was measured but not disclosed in the angiography guided group (n 1/4 174). Fractional flowreserve ≤0.80was an indication for revascularization by percutaneous coronary intervention (PCI) or coronary artery bypass surgery (CABG). The median (IQR) time from the index episode of myocardial ischaemia to angiographywas 3 (2, 5) days. For the primary outcome, the proportion of patients treated initially by medical therapy was higher in the FFR-guided group than in the angiography-guided group [40 (22.7%) vs. 23 (13.2%), difference 95% (95% CI: 1.4%, 17.7%), P 1/4 0.022]. Fractional flow reserve disclosure resulted in a change in treatment between medical therapy, PCI or CABG in 38 (21.6%) patients. At 12 months, revascularization remained lower in the FFR-guided group [79.0 vs. 86.8%, difference 7.8% (20.2%, 15.8%), P 1/4 0.054]. There were no statistically significant differences in health outcomes and quality of life between the groups.

Conclusion

In NSTEMI patients, angiography-guided management was associated with higher rates of coronary revascularization compared with FFR-guided management. A larger trial is necessary to assess health outcomes and cost-effectiveness.

Titanium-nitric-oxide-coated bioactive stents in acute coronary syndrome

REBLOG

Titanium-nitric-oxide-coated bioactive stents in acute coronary syndrome: towards a more clear landscape!

 Assisstant Professor of Cardiology, Faculty of Medicine, Ain Shams University, Egypt

With full interest, we read the Editorial “Nitric-oxide Coated Bioactive Titanium Stents: Safer and More Effective Than Second-generation Drug-eluting Stents?” by Sabaté et al 1. I’d like to commend the authors for publishing this interesting analysis of recently published studies – including the BASE ACS randomized controlled trial– comparing titanium-nitric-oxide-coated bioactive stents (NO-BAS) with drug-eluting stents. Yet, since I’m one of the authors of the BASE ACS trial, I’d like to clarify some points. First, the BASE ACS trial was adequately powered to detect a difference of the primary composite endpoint at 12 months (827 patients), with a formal statistical power calculation 2. Second, as the authors reported, the NO-BAS were non-inferior to cobalt-chromium-based everolimus-eluting stents (EES) for the primary composite endpoint of major adverse cardiac events (MACE) that included cardiac death, non-fatal myocardial infarction (MI), and ischemia-driven target lesion revascularization, in patients presenting with the full spectrum of acute coronary syndrome at 12-month follow-up 2. The 12-month rates of the individual secondary endpoints of non-fatal MI and definite stent thrombosis (ST) were lower in patients who received NO-BAS versus those who received EES (2.2% versus 5.9%, and 0.7% versus 2.2%, p= 0.007 and 0.07, respectively) 3. And whereas the definition of MI adopted by the BASE ACS trial (based on CK MB or troponin ≥2 times the upper reference limit) was different from that employed in the EXAMINATION trial (extended definition of the World Health Organization), it cannot be held responsible for the difference in MI rates between NO-BAS and EES in the same BASE ACS trial, since the definition was equally applied to the two trial arms 2,3. Third, the early (within 30 days) divergence of safety endpoints between the 2 stent arms is hard to explain merely in view of peri-procedural bivalirudin monotherapy. In fact, out of 9 cases (2.2%) of definite ST in the EES arm, 3 were acute (within 24 hr); out of these 3, only 2 received peri-procedural bivalirudin as a sole anticoagulant 2. Moreover, peri-procedural bivalirudin use was comparable between the 2 stent arms: 14.1% versus 15.1% in NO-BAS versus EES arms, respectively. Furthermore, angiographic success was achieved in 99.8% in both stent arms; hence, technical issues (distal dissection, stent underexpansion) were probably similar in the 2 stent arms 2. More importantly, the rates of non-fatal MI and definite ST continued to diverge after one year: at 2-year follow-up, they were 2.9% versus 7.1%, and 1.0% versus 2.7%, p= 0.005 and 0.05, for NO-BAS versus EES, respectively 4. Since technical issues generally operate early (within 1 month) after stent implantation; therefore, they cannot fully account for the ‘very late’ events. References

Abstract

Introduction and objectivesWe performed a pooled analysis based on patient-level data from the TITAX-AMI and BASE-ACS trials to evaluate the outcome of titanium-nitride-oxide-coated bioactive stents vs drug-eluting stents in patients with ST-segment elevation myocardial infarction at 2-year follow-up. MethodsThe TITAX-AMI trial compared bioactive stents with paclitaxel-eluting stents in 425 patients with acute myocardial infarction. The BASE-ACS trial compared bioactive stents with everolimus-eluting stents in 827 patients with acute coronary syndrome. The primary endpoint for the pooled analysis was major adverse cardiac events: a composite of cardiac death, recurrent myocardial infarction, or ischemia-driven target lesion revascularization at 2-year follow-up. ResultsThe pooled analysis included 501 patients; 245 received bioactive stents, and 256 received drug-eluting stents. The pooled bioactive stent group was associated with a risk ratio of 0.85 for major adverse cardiac events (95% confidence interval, 0.53-1.35; P = .49) compared to the pooled drug-eluting stent group. Similarly, the pooled bioactive stent group was associated with a risk ratio of 0.71 for cardiac death (95% confidence interval, 0.26-1.95; P = .51), 0.44 for recurrent myocardial infarction (95% confidence interval, 0.20-0.97; P = .04), and 1.39 for ischemia-driven target lesion revascularization (95% confidence interval, 0.74-2.59; P = .30), compared to the pooled drug-eluting stent group. These results were confirmed by propensity-score adjusted analysis of the combined datasets. ConclusionsIn patients with ST-segment elevation myocardial infarction, bioactive stents were associated with lower rates of recurrent myocardial infarction compared to drug-eluting stents at 2-year follow-up; yet, the rates of cardiac death and ischemia-driven target lesion revascularization were similar.

USPTO Guidance On Patentable Subject Matter

USPTO Guidance On Patentable Subject Matter

Curator and Reporter: Larry H Bernstein, MD, FCAP

Revised 4 July, 2014

http://pharmaceuticalintelligence.com/2014/07/03/uspto-guidance-on-patentable-subject-matter

 

I came across a few recent articles on the subject of US Patent Office guidance on patentability as well as on Supreme Court ruling on claims. I filed several patents on clinical laboratory methods early in my career upon the recommendation of my brother-in-law, now deceased.  Years later, after both brother-in-law and patent attorney are no longer alive, I look back and ask what I have learned over $100,000 later, with many trips to the USPTO, opportunities not taken, and a one year provisional patent behind me.

My conclusion is

(1) that patents are for the protection of the innovator, who might realize legal protection, but the cost and the time investment can well exceed the cost of startup and building a small startup enterprize, that would be the next step.

(2) The other thing to consider is the capability of the lawyer or firm that represents you.  A patent that is well done can be expected to take 5-7 years to go through with due diligence.   I would not expect it to be done well by a university with many other competing demands. I might be wrong in this respect, as the climate has changed, and research universities have sprouted engines for change.  Experienced and productive faculty are encouraged or allowed to form their own such entities.

(3) The emergence of Big Data, computational biology, and very large data warehouses for data use and integration has changed the landscape. The resources required for an individual to pursue research along these lines is quite beyond an individuals sole capacity to successfully pursue without outside funding.  In addition, the changed designated requirement of first to publish has muddied the water.

Of course, one can propose without anything published in the public domain. That makes it possible for corporate entities to file thousands of patents, whether there is actual validation or not at the time of filing.  It would be a quite trying experience for anyone to pursue in the USPTO without some litigation over ownership of patent rights. At this stage of of technology development, I have come to realize that the organization of research, peer review, and archiving of data is still at a stage where some of the best systems avalailable for storing and accessing data still comes considerably short of what is needed for the most complex tasks, even though improvements have come at an exponential pace.

I shall not comment on the contested views held by physicists, chemists, biologists, and economists over the completeness of guiding theories strongly held.  Only history will tell.  Beliefs can hold a strong sway, and have many times held us back.

I am not an expert on legal matters, but it is incomprehensible to me that issues concerning technology innovation can be adjudicated in the Supreme Court, as has occurred in recent years. I have postgraduate degrees in  Medicine, Developmental Anatomy, and post-medical training in pathology and laboratory medicine, as well as experience in analytical and research biochemistry.  It is beyond the competencies expected for these type of cases to come before the Supreme Court, or even to the Federal District Courts, as we see with increasing frequency,  as this has occurred with respect to the development and application of the human genome.

I’m not sure that the developments can be resolved for the public good without a more full development of an open-access system of publishing. Now I present some recent publication about, or published by the USPTO.

Abstract In June 2013, the U.S. Supreme Court issued a unanimous decision upending more than three decades worth of established patent practice when it ruled that isolated gene sequences are no longer patentable subject matter under 35 U.S.C. Section 101.While many practitioners in the field believed that the USPTO would interpret the decision narrowly, the USPTO actually expanded the scope of the decision when it issued its guidelines for determining whether an invention satisfies Section 101.

The guidelines were met with intense backlash with many arguing that they unnecessarily expanded the scope of the Supreme Court cases in a way that could unduly restrict the scope of patentable subject matter, weaken the U.S. patent system, and create a disincentive to innovation. By undermining patentable subject matter in this way, the guidelines may end up harming not only the companies that patent medical innovations, but also the patients who need medical care.  This article examines the guidelines and their impact on various technologies.

INTELLECTUAL PROPERTY

Biotech feels a chill from changing U.S. patent rules

A 2013 Supreme Court decision that barred human gene patents is scrambling patenting policies.

A year after the U.S. Supreme Court issued a landmark ruling that human genes cannot be patented, the biotech industry is struggling to adapt to a landscape in which inventions derived from nature are increasingly hard to patent. It is also pushing back against follow-on policies proposed by the U.S. Patent and Trademark Office (USPTO) to guide examiners deciding whether an invention is too close to a natural product to deserve patent protection. Those policies reach far beyond what the high court intended, biotech representatives say.

“Everything we took for granted a few years ago is now changing, and it’s generating a bit of a scramble,” says patent attorney Damian Kotsis of Harness Dickey in Troy, Michigan, one of more than 15,000 people who gathered here last week for the Biotechnology Industry Organization’s (BIO’s) International Convention.

At the meeting, attorneys and executives fretted over the fate of patent applications for inventions involving naturally occurring products—including chemical compounds, antibodies, seeds, and vaccines—and traded stories of recent, unexpected rejections by USPTO. Industry leaders warned that the uncertainty could chill efforts to commercialize scientific discoveries made at universities and companies. Some plan to appeal the rejections in federal court.

USPTO officials, meanwhile, implored attendees to send them suggestions on how to clarify and improve its new policies on patenting natural products, and even announced that they were extending the deadline for public comment by a month. “Each and every one of you in this room has a moral duty … to provide written comments to the PTO,” patent lawyer and former USPTO Deputy Director Teresa Stanek Rea told one audience.

At the heart of the shake-up are two Supreme Court decisions: the ruling last year in Association for Molecular Pathology v. Myriad Genetics Inc. that human genes cannot be patented because they occur naturally (Science, 21 June 2013, p. 1387); and the 2012 Mayo v. Prometheus decision, which invalidated a patent on a method of measuring blood metabolites to determine drug doses because it relied on a “law of nature” (Science, 12 July 2013, p. 137).

Myriad and Mayo are already having a noticeable impact on patent decisions, according to a study released here. It examined about 1000 patent applications that included claims linked to natural products or laws of nature that USPTO reviewed between April 2011 and March 2014. Overall, examiners rejected about 40%; Myriad was the basis for rejecting about 23% of the applications, and Mayo about 35%, with some overlap, the authors concluded. That rejection rate would have been in the single digits just 5 years ago, asserted Hans Sauer, BIO’s intellectual property counsel, at a press conference. (There are no historical numbers for comparison.) The study was conducted by the news service Bloomberg BNA and the law firm Robins, Kaplan, Miller & Ciseri in Minneapolis, Minnesota.

USPTO is extending the decisions far beyond diagnostics and DNA?

The numbers suggest USPTO is extending the decisions far beyond diagnostics and DNA, attorneys say. Harness Dickey’s Kotsis, for example, says a client recently tried to patent a plant extract with therapeutic properties; it was different from anything in nature, Kotsis argued, because the inventor had altered the relative concentrations of key compounds to enhance its effect. Nope, decided USPTO, too close to nature.

In March, USPTO released draft guidance designed to help its examiners decide such questions, setting out 12 factors for them to weigh. For example, if an examiner deems a product “markedly different in structure” from anything in nature, that counts in its favor. But if it has a “high level of generality,” it gets dinged.

The draft has drawn extensive criticism. “I don’t think I’ve ever seen anything as complicated as this,” says Kevin Bastian, a patent attorney at Kilpatrick Townsend & Stockton in San Francisco, California. “I just can’t believe that this will be the standard.”

USPTO officials appear eager to fine-tune the draft guidance, but patent experts fear the Supreme Court decisions have made it hard to draw clear lines. “The Myriad decision is hopelessly contradictory and completely incoherent,” says Dan Burk, a law professor at the University of California, Irvine. “We know you can’t patent genetic sequences,” he adds, but “we don’t really know why.”

Get creative in using Draft Guidelines!

For now, Kostis says, applicants will have to get creative to reduce the chance of rejection. Rather than claim protection for a plant extract itself, for instance, an inventor could instead patent the steps for using it to treat patients. Other biotech attorneys may try to narrow their patent claims. But there’s a downside to that strategy, they note: Narrower patents can be harder to protect from infringement, making them less attractive to investors. Others plan to wait out the storm, predicting USPTO will ultimately rethink its guidance and ease the way for new patents.

 

Public comment period extended

USPTO has extended the deadline for public comment to 31 July, with no schedule for issuing final language. Regardless of the outcome, however, Stanek Rea warned a crowd of riled-up attorneys that, in the world of biopatents, “the easy days are gone.”

The FDA published its new Guidance for Industry (GfI) – “Electronic Source Data in Clinical Investigations” in September 2013.
The Guidance defines the expectations of the FDA concerning electronic source data generated in the context of clinical trials. Find out more about this Guidance.

After more than 5 years and two draft versions, the final version of the Guidance for
Industry (GfI) – “Electronic Source Data in Clinical Investigations” was published in
September 2013. This new FDA Guidance defines the FDA’s expectations for sponsors,
CROs, investigators and other persons involved in the capture, review and retention of
electronic source data generated in the context of FDA-regulated clinical trials.In an
effort to encourage the modernization and increased efficiency of processes in clinical
trials, the FDA clearly supports the capture of electronic source data and emphasizes
the agency’s intention to support activities aimed at ensuring the reliability, quality,
integrity and traceability of this source data, from its electronic source to the electronic
submission of the data in the context of an authorization procedure. The Guidance
addresses aspects as data capture, data review and record retention. When the
computerized systems used in clinical trials are described, the FDA recommends
that the description not only focus on the intended use of the system, but also on
data protection measures and the flow of data across system components and
interfaces. In practice, the pharmaceutical industry needs to meet significant
requirements regarding organisation, planning, specification and verification of
computerized systems in the field of clinical trials. The FDA also mentions in the
Guidance that it does not intend to apply 21 CFR Part 11 to electronic health records
(EHR). Author: Oliver Herrmann Q-Infiity Source: http://www.fda.gov/downloads/Drugs/GuidanceComplianceRegulatoryInformation/
