With an increasingly aging global population, neurological disorders have become a major cause of death and disability worldwide. Despite the significant investments that continue to be made in research and development in the neurological field, the discovery of new drugs targeting many CNS disorders, including Alzheimer’s and Parkinson’s diseases, has proved to be difficult. Often the share values of companies in that area can exhibit wild swings related to success or failure in clinical trials. In addition, the COVID-19 pandemic is requiring companies to readjust their clinical trial schedules and programs. Those pressures have weighed on members of the BioWorld Neurological Diseases index, which has slipped about 4% in value so far this year.
About six months after Epizyme Inc. won FDA clearance of Tazverik (tazemetostat) for epithelial sarcoma, the firm scored accelerated approval in the larger indication of relapsed or refractory follicular lymphoma. Specifically, U.S. regulators cleared the methyltransferase inhibitor for adults whose tumors test positive for an EZH2 mutation who have received at least two prior systemic therapies and for those with no satisfactory alternative treatment options.
Evoke Pharma Inc. gained FDA approval for Gimoti (metoclopramide), a nasal spray formulation of metoclopramide designed to inhibit dopamine D2 and serotonin 5-HT3 receptors, for adults with acute and recurrent diabetic gastroparesis.
The FDA approved checkpoint blocker Keytruda (pembrolizumab, Merck & Co. Inc.) “for the treatment of adult and pediatric patients with unresectable or metastatic tumor mutational burden-high (TMB-H) [≥10 mutations/megabase (mut/Mb)] solid tumors, as determined by an FDA-approved test, that have progressed following prior treatment and who have no satisfactory alternative treatment options.”
Pharmamar SA and partner Jazz Pharmaceuticals plc received an accelerated FDA approval of Zepzelca (lurbinectedin) to treat relapsed metastatic small-cell lung cancer patients. The approval potentially triggers a $250 million payment to Pharmamar based on its commercialization deal signed with Jazz last December. It also offers a new option for patients, having shown a 35% overall response rate (ORR). The historical ORR rate for the chemotherapy topotecan is 16.9%. Zepzelca, an alkylating drug that binds guanine residues within DNA, will be used specifically for those adult patients with disease progression during or following platinum-based chemotherapy.
The EU has secured a supply of the most advanced COVID-19 vaccine in development, in a deal with Astrazeneca plc for up to 400 million doses of AZD-1222, with deliveries starting by the end of 2020. The agreement has been signed with the “inclusive vaccines alliance” formed by Germany, France, Italy and the Netherlands, but will also make AZD-1222 available for other countries in Europe. While the four countries spearheaded this negotiation, on June 12, EU health ministers gave the European Commission a mandate to negotiate advance purchase agreements for up to six different COVID-19 vaccines, for all member states, using a €2.3 billion (US$2.6 billion) emergency fund.
Just 80 days after first issuing an emergency use authorization (EUA) for oral formulations of chloroquine phosphate (CQ) and hydroxychloroquine sulfate (HCQ) in treating COVID-19, the FDA said it is revoking that authorization in light of clinical data and scientific literature that raised questions about whether benefits of the treatment outweigh the risks. Following the review, the agency determined that the suggested dosing regimens for CQ and HCQ detailed in earlier health provider fact sheets are unlikely to produce an antiviral effect.
In the first major breakthrough in therapeutics for COVID-19 infection, dexamethasone has been shown to have a statistically significant impact on mortality in the most seriously ill patients. There was a one-third reduction in deaths in patients on ventilators, while in patients receiving oxygen therapy there was a 15% reduction in 28-day mortality, in the U.K. Recovery trial. No benefit was seen in patients who were sick enough to be in the hospital but did not need help breathing. The steroid was delivered either orally or intravenously at a dose of 6 mg per day. In total, 2,104 patients were randomized to the active arm and 4,321 to standard of care. There were no serious treatment-related adverse events.

The production agreement is part of Astrazeneca's recently disclosed, in-licensed program with the University of Oxford to ensure broad and equitable supply of the vaccine throughout the world, at no profit during the COVID-19 pandemic. Shares of Humanigen Inc. climbed 30.2% last week after the company disclosed that, when treated with the company's anti-GM-CSF antibody, lenzilumab, 12 hospitalized patients with severe or critical pneumonia as a result of COVID-19 showed "rapid clinical improvement." Median time to recovery and discharge for the group was five days. The research, based on compassionate use of the experimental therapy at Mayo Clinic, precedes a registration-directed phase III trial in COVID-19 pneumonia patients that the company is currently enrolling. Sinovac Biotech Ltd. said the preliminary results of the phase I/II trials of its COVID-19 inactivated vaccine candidate, Coronavac, demonstrated favorable immunogenicity and safety profiles. The company said it aims to move it to phase III trials outside China next month. The positive results were unveiled less than two months after the study started. Staidson Biopharma Inc. and European CRO Pivotal said they are collaborating to assess Staidson’s BDB-001, a monoclonal anti-C5a antibody, in a Europe-based clinical trial in progressive severe COVID-19. Treos Bio Ltd. has developed a preventive COVID-19 peptide vaccine, PolyPEPI-SCoV-2, and has transferred all rights, including pending patent applications, to a newly formed subsidiary, Peptc Vaccines Ltd.

The U.S. Patent and Trademark Office (USPTO) launched a new program to advance the initial examination of applications for trademarks and service marks used to identify qualifying COVID-19 medical products and services. The program is open to applications for products subject to FDA approval for use in the prevention or treatment of COVID-19 or a medical or medical research service to prevent or treat the coronavirus infections. In addition to expediting the examination, the USPTO will waive the fee for the petitions.
The U.S. District Court for the Northern District of West Virginia ruled against Biogen Inc. and in favor of Mylan NV in a patent dispute regarding Biogen’s blockbuster multiple sclerosis drug, Tecfidera (dimethyl fumarate). The court ruled that Mylan “has established by clear and convincing evidence that the asserted claims of the [8,399,514] Patent are invalid for lack of written description,” thereby invalidating the patent, which provides exclusivity protection to the drug until February 2028. Biogen can appeal the decision, which analysts expect will take 12 to 18 months.
Word on the Street: Industry responses to the issues of the week
“This is an extremely welcome result. The survival benefit is clear and large in those patients who are sick enough to require oxygen treatment, so dexamethasone should now become standard of care in these patients. Dexamethasone is inexpensive, on the shelf, and can be used immediately to save lives worldwide.”
Peter Horby, professor of emerging infectious diseases at Oxford University, and one of the chief investigators for the U.K. Recovery trial
"Entrepreneurs just need someone to give them a chance. The sponsors of those Golden Tickets give those companies a chance to prove that what they're going after is possible, and without that opportunity some companies might not exist."
Robert Blazej, director at MBC Biolabs and a partner at Mission Bay Capital, on the Golden Ticket program in which recipients receive 12 months of lab bench space and access to core facilities at MBC Biolabs' incubator, paid for by multiple large drug companies that sponsor the program
“Inventors and entrepreneurs are working around the clock to develop products that will help prevent, diagnose, treat or cure COVID-19. Accelerating initial examination of COVID-19-related trademark applications for these products … will help to bring important and possibly life-saving treatments to market more quickly.”
