“Repurposing” Off-patent Drugs offers big hopes of New Treatments

Reporter: Irina Robu, PhD

 

Given the substantial costs and the slow pace of drug discovery and development, repurposing old drugs has become a practice, partly because it involves the use of already developed compounds. Yet, there is lack of clinical interest in repurposing off patent drugs.

However, the scale of the opportunity for drug repurposing is huge. Initially approved for one disease, these drugs went off-patent and now show potential in other diseases. Even so, many non-profit groups see promise in supporting trials into drug repurposing. There is a huge untapped medicine chest of generic drugs with unexploited uses. These generic drugs are often cheap, already approved, off-patent and relatively quick to develop, whereas new drugs can cost millions of dollars to develop, test and 45% of the drugs fail in clinical trials.

However, numerous non-profit groups see potential in supporting trials into drug repurposing. Epidemiological data can offer enticing leads. Yet, clinical trials for these drugs are costly, but the benefits can be huge. The Drugs for Neglected Diseases Initiative, a Swiss non-profit research group, supported research into fexinidazole, which was abandoned by a pharma at an early stage. The drug showed to have antiparasitic qualities. However, after years of work in January 2020, it was approved for sleeping sickness in the Democratic Republic of Congo. It is the first oral medicine for the disease, and works for all stages of it.

Up till now, when it comes to cancer the most promising generic pills are known. Cancer Research, a UK based charity is testing aspirin to see if can stop cancer from recurring; metformin in a large prostate-cancer trial; and an anti-fungal medication to treat bowel cancer. At the same time, the Anticancer Fund in Brussels hopes that propranolol in treating cancers of the inner lining of blood vessels and pancreatic cancer. Propranolol is a generic 1960s beta-blocker used for a wide range of ailments such as hypertension, anxiety and migraine. If approved for cancer, its cost would be negligible in comparison the tens of thousands of dollars a month usually charged for cancer medicines.

Money seems the crucial constraint with these drugs, in addition to the clinical trials needed to have these drugs updated and relabeled. Only the makers or original developers of a drug are permitted to adjust its label. Sanofi, based in Paris, was the firm that requested regulatory review of fexinidazole for sleeping sickness, while the research was a charitable effort. But drug firms are not forced to support non-commercial efforts to repurpose drugs. And outside the industry it is tough to find the legal expertise to be able to do the  necessary paperwork.

As non-profits make progress in repurposing, corporate interest may be rising. In terms of achieving new treatment options, this is good news. But it will not bring cheaper medicines in areas traditionally neglected by the drug industry. Firms will focus on finding ways to patent the new uses and charge high prices for the finished product.

If governments need cheaper drugs, non-profits will need financial incentives and a cooperative regulatory framework. They include making regulators give free advice and waive approval fees, and a public fund to support repurposing. Yet, when drugs are approved, investors are paid back by the public health service, which makes savings by using the newly approved generic drugs.

Accelerating COVID-19 Therapeutic Interventions and Vaccines (ACTIV) An Unprecedented Partnership for Unprecedented Times

JAMA. Published online May 18, 2020. doi:10.1001/jama.2020.8920

First reported in Wuhan, China, in December 2019, COVID-19 is caused by a highly transmissible novel coronavirus, SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2). By March 2020, as COVID-19 moved rapidly throughout Europe and the US, most researchers and regulators from around the world agreed that it would be necessary to go beyond “business as usual” to contain this formidable infectious agent. The biomedical research enterprise was more than willing to respond to the challenge of COVID-19, but it soon became apparent that much-needed coordination among important constituencies was lacking.

Clinical trials of investigational vaccines began as early as January, but with the earliest possible distribution predicted to be 12 to 18 months away. Clinical trials of experimental therapies had also been initiated, but most, except for a trial testing the antiviral drug remdesivir,2 were small and not randomized. In the US, there was no true overarching national process in either the public or private sector to prioritize candidate therapeutic agents or vaccines, and no efforts were underway to develop a clear inventory of clinical trial capacity that could be brought to bear on this public health emergency. Many key factors had to change if COVID-19 was to be addressed effectively in a relatively short time frame.

On April 3, leaders of the National Institutes of Health (NIH), with coordination by the Foundation for the National Institutes of Health (FNIH), met with multiple leaders of research and development from biopharmaceutical firms, along with leaders of the US Food and Drug Administration (FDA), the Biomedical Advanced Research and Development Authority (BARDA), the European Medicines Agency (EMA), and academic experts. Participants sought urgently to identify research gaps and to discuss opportunities to collaborate in an accelerated fashion to address the complex challenges of COVID-19.

These critical discussions culminated in a decision to form a public-private partnership to focus on speeding the development and deployment of therapeutics and vaccines for COVID-19. The group assembled 4 working groups to focus on preclinical therapeutics, clinical therapeutics, clinical trial capacity, and vaccines (Figure). In addition to the founding members, the working groups’ membership consisted of senior scientists from each company or agency, the Centers for Disease Control and Prevention (CDC), the Department of Veterans Affairs (VA), and the Department of Defense.

Accelerating COVID-19 Therapeutic Interventions and Vaccines

ACTIV’s 4 working groups, each with one cochair from NIH and one from industry, have made rapid progress in establishing goals, setting timetables, and forming subgroups focused on specific issues (Figure). The goals of the working group, along with a few examples of their accomplishments to date, include the following.

 

The Preclinical Working Group was charged to standardize and share preclinical evaluation resources and methods and accelerate testing of candidate therapies and vaccines to support entry into clinical trials. The aim is to increase access to validated animal models and to enhance comparison of approaches to identify informative assays. For example, through the ACTIV partnership, this group aims to extend preclinical researchers’ access to high-throughput screening systems, especially those located in the Biosafety Level 3 (BSL3) facilities currently required for many SARS-CoV-2 studies. This group also is defining a prioritization approach for animal use, assay selection and staging of testing, as well as completing an inventory of animal models, assays, and BSL 3/4 facilities.

 

The Therapeutics Clinical Working Group has been charged to prioritize and accelerate clinical evaluation of a long list of therapeutic candidates for COVID-19 with near-term potential. The goals have been to prioritize and test potential therapeutic agents for COVID-19 that have already been in human clinical trials. These may include agents with either direct-acting or host-directed antiviral activity, including immunomodulators, severe symptom modulators, neutralizing antibodies, or vaccines. To help achieve these goals, the group has established a steering committee with relevant expertise and objectivity to set criteria for evaluating and ranking potential candidate therapies submitted by industry partners. Following a rigorous scientific review, the prioritization subgroup has developed a complete inventory of approximately 170 already identified therapeutic candidates that have acceptable safety profiles and different mechanisms of action. On May 6, the group presented its first list of repurposed agents recommended for inclusion in ACTIV’s master protocol for adaptive clinical trials. Of the 39 agents that underwent final prioritization review, the group identified 6 agents—including immunomodulators and supportive therapies—that it proposes to move forward into the master protocol clinical trial(s) expected to begin later in May.

 

The Clinical Trial Capacity Working Group is charged with assembling and coordinating existing networks of clinical trials to increase efficiency and build capacity. This will include developing an inventory of clinical trial networks supported by NIH and other funders in the public and private sectors, including contract research organizations. For each network, the working group seeks to identify their specialization in different populations and disease stages to leverage infrastructure and expertise from across multiple networks, and establish a coordination mechanism across networks to expedite trials, track incidence across sites, and project future capacity. The clinical trials inventory subgroup has already identified 44 networks, with access to adult populations and within domestic reach, for potential inclusion in COVID-19 trials. Meanwhile, the survey subgroup has developed 2 survey instruments to assess the capabilities and capacities of those networks, and its innovation subgroup has developed a matrix to guide deployment of innovative solutions throughout the trial life cycle.

 

The Vaccines Working Group has been charged to accelerate evaluation of vaccine candidates to enable rapid authorization or approval.4 This includes development of a harmonized master protocol for adaptive trials of multiple vaccines, as well as development of a trial network that could enroll as many as 100 000 volunteers in areas where COVID-19 is actively circulating. The group also aims to identify biomarkers to speed authorization or approval and to provide evidence to address cross-cutting safety concerns, such as immune enhancement. Multiple vaccine candidates will be evaluated, and the most promising will move to a phase 2/3 adaptive trial platform utilizing large geographic networks in the US and globally.5 Because time is of the essence, ACTIV will aim to have the next vaccine candidates ready to enter clinical trials by July 1, 2020.

ABBV-184: A novel survivin specific T cell receptor/CD3 bispecific therapeutic that targets both solid tumor and hematological malignancies

Edward B Reilly
AbbVie Inc. @abbvie

  • T-cell receptors (TCR) can recognize the intracellular targets whereas antibodies only recognize the 25% of potential extracellular targets
  • survivin is expressed in multiple cancers and correlates with poor survival and prognosis
  • CD3 bispecific TCR to survivn (Ab to CD3 on T- cells and TCR to survivin on cancer cells presented in MHC Class A3)
  • ABBV184  effective in vivo in lung cancer models as single agent;
  • in humanized mouse tumor models CD3/survivin bispecific can recruit T cells into solid tumors; multiple immune cells CD4 and CD8 positive T cells were found to infiltrate into tumor
  • therapeutic window as measured by cytokine release assays in tumor vs. normal cells very wide (>25 fold)
  • ABBV184 does not bind platelets and has good in vivo safety profile
  • First- in human dose determination trial: used in vitro cancer cell assays to determine 1st human dose
  • looking at AML and lung cancer indications
  • phase 1 trial is underway for safety and efficacy and determine phase 2 dose
  • survivin has very few mutations so they are not worried about a changing epitope of their target TCR peptide of choice

The discovery of TNO155: A first in class SHP2 inhibitor

Matthew J. LaMarche
Novartis @Novartis

  • SHP2 is an intracellular phosphatase that is upstream of MEK ERK pathway; has an SH2 domain and PTP domain
  • knockdown of SHP2 inhibits tumor growth and colony formation in soft agar
  • 55 TKIs there are very little phosphatase inhibitors; difficult to target the active catalytic site; inhibitors can be oxidized at the active site; so they tried to target the two domains and developed an allosteric inhibitor at binding site where three domains come together and stabilize it
  • they produced a number of chemical scaffolds that would bind and stabilize this allosteric site
  • block the redox reaction by blocking the cysteine in the binding site
  • lead compound had phototoxicity; used SAR analysis to improve affinity and reduce phototox effects
  • was very difficult to balance efficacy, binding properties, and tox by adjusting stuctures
  • TNO155 is their lead into trials
  • SHP2 expressed in T cells and they find good combo with I/O with uptick of CD8 cells
  • TNO155 is very selective no SHP1 inhibition; SHP2 can autoinhibit itself when three domains come together and stabilize; no cross reactivity with other phosphatases
  • they screened 1.5 million compounds and got low hit rate so that is why they needed to chemically engineer and improve on the classes they found as near hits

Abstract: The ubiquitously expressed protein tyrosine phosphatase SHP2 is required for signalling downstream of receptor tyrosine kinases (RTKs) and plays a role in regulating many cellular processes. Recent advances have shown that genetic knockdown and pharmacological inhibition of SHP2 suppresses RAS/MAPK signalling and inhibits proliferation of RTK-driven cancer cell lines. SHP2 is now understood to act upstream of RAS and plays a role in KRAS-driven cancers, an area of research which is rapidly growing. Considering that RTK deregulation often leads to a wide range of cancers and the newly appreciated role of SHP2 in KRAS-driven cancers, SHP2 inhibitors are therefore a promising therapeutic approach.
SHP2 contains two N-terminal tandem SH2 domains (N-SH2, C-SH2), a catalytic phosphatase domain and a C-terminal tail. SHP2 switches between “open” active and “closed” inactive forms due to autoinhibitory interactions between the N-SH2 domain and the phosphatase domain. Historically, phosphatases were deemed undruggable as there had been no advancements with active site inhibitors. We hypothesised that fragment screening would be highly applicable and amenable to this target to enable alternative means of inhibition through identification of allosteric binding sites. Here we describe the first reported fragment screen against SHP2.
Using our fragment-based PyramidTM approach, screening was carried out on two constructs of SHP2; a closed autoinhibited C-terminal truncated form (phosphatase and both SH2 domains), as well as the phosphatase-only domain. A combination of screening methods such as X-ray crystallography and NMR were employed to identify fragment hits at multiple sites on SHP2, including the tunnel-like allosteric site reported by Chen et al, 2016. Initial fragment hits had affinities for SHP2 in the range of 1mM as measured by ITC. Binding of these hits was improved using structure-guided design to generate compounds which inhibit SHP2 phosphatase activity and are promising starting points for further optimization.

  • anti estrogen receptor therapy: ER degraders is one class
  • AZ9833 enhances degradation of ER alpha
  • worked in preclinical mouse model (however very specific)
  • PK parameters were good for orally available in rodents;  also in vitro and in vivo correlation correlated in rats but not in dogs so they were not sure if good to go in humans
  • they were below Km in rats but already at saturated in dogs, dogs were high clearance
  • predicted human bioavailability at 40%

The Problem and Challenges of Commercialization

Curator and Reporter: Joel Shertok, PhD

 

As the old saying goes,

Anybody can do something once; the problem is: can you do it twice, or for that matter, over and over again?

This is the essential issue faced by those personnel in the throes of the commercialization process.

Any successful commercial process has to meet a number of criteria:

  1. The process must be reproducible — it must yield the same product/results given the same inputs.
  2. The process must be economically viable: given the constraints of raw material, energy, and labor costs, depreciation schedules for equipment, expected process failures, R/D, Marketing, and Sales support costs, the process needs to yield both a profit and positive cash flow
  3. The process should be implemented using readily available commercial components and control instrumentation. On occasion, successful implementation of a project will require specialized components; however these components themselves must meet the criteria for successful commercialization
  4. The process must be “simple” enough so that suitably trained operators can manage the process. A unit that requires Ph.D.’s to maintain operations is doomed to failure

History is replete with novel processes that worked on the lab scale, but were failures when a commercial operation was attempted. The issues that are most responsible for lab-to-production failure are listed under the general classification of “scale-up”. Scale-up principles are covered in my monograph, “The Art of Scale-up” (www.artofscaleup.com), but in general follow these rules:

  • Identification of those process parameters that will have major impact on commercial viability: reaction kinetics, mass transfer vs. temperature/kinetic control; if multi-phase systems are involved, the type and energy of required stirring; heat transfer considerations; side reactions; etc.

  • Materials of construction; raw material and product hazards; etc.

  • Regulatory considerations: FDA, OSHA, EPA.

Failure to address any of these issues prior to commercialization will lead to surprises during commercialization.

In addition to the engineering/scale-up aspects of commercialization, there are several other criteria that may need attention:

  1. When to launch a product – where will the new product fit into the overall corporate product portfolio?
  2. Where is the proper location to launch?  A product aimed at flu symptom suppression in cold-weather conditions may not do well in Florida; ….. super-sweet tea does well in the South, and not so well in New England, so that a product to replace sugar might do well in the South.
  3. Who is going to use the product?  Are you targeting doctor’s offices, hospitals, or direct to consumer routes?
  4. How to launch – social media and “influencers” have given rise to new avenues of product introductions.

The old aphorism of “measure twice, cut once” has a special resonance when doing commercialization of a new process or product. The more the process is thought out ahead of time, the less issues there will be down the road. In the commercial world, there is constant pressure to rush things to meet management deadlines, which always leads to problems and extra expense. A crusty of R/D chemist once remarked, “There is never time to do it right, but always time to do it twice.” Everyone needs to keep this in the back of their mind

Advancing Drug Development – 12/12/2019, 8:30AM – 8:30PM at The University of Massachusetts Club, One Beacon Street, Boston, MA

 

Reporter: Aviva Lev-Ari, PhD, RN

4th Advancing Drug Development Forum – Making the Impossible Possible – Harnessing Small Molecule Drug Development scheduled to take place December 12th, 2019 at The University of Massachusetts Club, in Boston, Massachusetts from 8:30 AM – 8:30 PM.

http://advdrug.com/agenda/

 

Scientists are more than just chipping away and kicking down the barricades to develop complex small molecule products better and faster.  Successful companies are spending quality time finding novel and clever approaches and powerful technologies to better support their knowledgeable teams.  Often it takes establishing strong partnerships with 1 or more specialized service providers, cleverly combining resources – always striving to raise the bar in order to make life threatening diseases more of a chronic and tolerable disease or eradicated completely.

Hear from key opinion leaders in pharma, biotech, the investment community and innovative service providers on how they are meeting the challenges. Keep in mind, it takes being open-minded, flexible and willing sometimes to redesigning a new formulation that better enhances bioavailability, optimizes drug-delivery profiles, reduces dosing frequency, or improves the patient experience to have the potential to deliver quicker returns on investments than developing a completely new drug.

Pfizer buys out Array BioPharma for $11.4 Billion to beef up its oncology offerings

Reporter: Stephen J. Williams, PhD

As reported in FiercePharma.com:

by Angus Liu |

Three years after purchasing Medivation for $14.3 billion, Pfizer is back with another hefty M&A deal. And once again, it’s betting on oncology.

In the first big M&A deal under new CEO Albert Bourla, Pfizer has agreed to buy oncology specialist Array BioPharma for a total value of about $11.4 billion, the two companies unveiled Monday. The $48-per-share offer represents a premium of about 62% to Array stock’s closing price on Friday.

With the acquisition, Pfizer will beef up its oncology offerings with two marketed drugs, MEK inhibitor Mektovi and BRAF inhibitor Braftovi, which are approved as a combo treatment for melanoma and recently turned up positive results in colon cancer.

The buy will enhance the Pfizer innovative drug business’ “long-term growth trajectory,” Bourla said in a Monday statement, dubbing Mektovi-Braftovi “a potentially industry-leading franchise for colorectal cancer.”

RELATED: Array’s ‘extremely compelling’ new colon cancer data spark blockbuster talk

In a recent interim analysis of a trial in BRAF-mutant metastatic colorectal cancer, the pair, used in tandem with Eli Lilly and Merck KGaA’s Erbitux, produced a benefit in 26% of patients, versus the 2% that chemotherapy helped. The combo also showed it could reduce the risk of death by 48%. SVB Leerink analysts at that time called the data “extremely compelling.”

Right now, one in every three new patients with mutated metastatic melanoma is getting the combo, despite its third-to-market behind combos from Roche and Novartis, Andy Schmeltz, Pfizer’s oncology global president, said during an investor briefing on Monday.

It is being studied in more than 30 clinical studies across several solid tumor indications. Moving forward, Pfizer believes the combo could potentially be used in the adjuvant setting to prevent tumor recurrence after surgery, Pfizer’s chief scientific officer, Mikael Dolsten, said on the call. The company is also keen to know how it could be paired up with Pfizer’s own investigational PD-1, he said, as the combo is already in studies with other PD-1/L1s.

But as Pfizer execs have previously said, the company’s current business development strategy no longer centers on adding revenues “now or soon,” but rather on strengthening Pfizer’s pipeline with earlier-stage assets. And Array can help there, too.

“We are very excited by Array’s impressive track record of successfully discovering and developing innovative small-molecules and targeted cancer therapies,” Dolsten said in a statement.

On top of Mektovi and Braftovi, Array has a long list of out-licensed drugs that could generate big royalties over time. For example, Vitrakvi, the first drug to get an initial FDA approval in tumors with a particular molecular feature regardless of their location, was initially licensed to Loxo Oncology—which was itself snapped up by Eli Lilly for $8 billion—but was taken over by pipeline-hungry Bayer. There are other drugs licensed to the likes of AstraZeneca, Roche, Celgene, Ono Pharmaceutical and Seattle Genetics, among others.

Those drugs are also a manifestation of Array’s strong research capabilities. To keep those Array scientists doing what they do best, Pfizer is keeping a 100-person team in Colorado as a standalone research unit alongside Pfizer’s existing hubs, Schmeltz said.

Pfizer is counting on Array to augment its leadership in breast cancer, an area championed by Ibrance, and prostate cancer, the pharma giant markets Astellas-partnered Xtandi. For 2018, revenues from the Pfizer oncology portfolio jumped to $7.20 billion—up from $6.06 billion in 2017—mainly thanks to those two drugs.

Real Time Coverage @BIOConvention #BIO2019: June 4 Morning Sessions; Global Biotech Investment & Public-Private Partnerships

Reporter: Stephen J Williams PhD @StephenJWillia2

Each country have their own needs and most important drug cost structure. Must involve patients and providers.
BCI survey: countries output different, who improved who didnt
Is industry having collaboration with government? hardly ten percent by survey and worse vice versa
Transparancy and holistic view important for collaboration
Korea: lack of communication need input from government on pricing; wants global open innovation and enhance RD investments
Tawain: price, price but based on efficacy; pharma needs to talk with doctors hospital patients, find balance
Pitts: we need trust; staff that country offices with people who know that country. Price not defining value
Columbia:  need to attract investors
