How flexible should the U.S. FDA evidentiary standards be for a therapy addressing a significant unmet need in a disease such as amyotrophic lateral sclerosis (ALS)? That’s the question the agency’s Cellular, Tissue and Gene Therapies Advisory Committee will ponder Sept. 27 as it looks at the data for Brainstorm Cell Therapuetics Inc.’s Nurown (debamestrocel), a mesenchymal stromal cell therapy targeting ALS. Nurown is going into the adcom with a bit of a checkered history that includes a refuse-to-file letter and a single phase III trial that failed to demonstrate efficacy for the primary endpoint and all key secondary efficacy endpoints, according to the FDA briefing document.
Safety concerns overrode benefit when the U.S. FDA’s Endocrinologic and Metabolic Drugs Advisory Committee (EMDAC) voted unanimously, 19-0, Sept. 21 that the potential risks of Intarcia Therapeutics’ ITCA-650 outweighed the compliance and A1C-lowering benefits the twice-yearly implantable exenatide-device combination product could provide for adults with type 2 diabetes.
The U.S. FDA is going straight to final guidance with its “Considerations for the conduct of clinical trials of medical products during major disruptions due to disasters and public health emergencies [PHEs].”
Shares of ARS Pharmaceuticals Inc. (NASDAQ:SPRY) plummeted 55.8% Sept. 20 on word that the U.S. FDA issued a complete response letter (CRL) for Neffy, despite receiving a recommendation for approval in May from the agency’s advisory committee (adcom) and following a three-month delay in action.
A Sept. 21 U.S. FDA advisory committee meeting will either be a “Hail Mary” or a last gasp of life for ITCA-650, a twice-yearly implantable exenatide-device combination product intended to improve glycemic control in adults with type 2 diabetes.
Developers of combination products face an unusual dilemma in their interactions with the U.S. FDA, given that the data for the constituent products reside in multiple product centers. Some of the related clunkiness may soon be a thing of the past thanks to a new four-year proposal to overhaul the FDA’s information technology infrastructure, which among other things will emphasize a more seamless sharing of data across centers, precisely the kind of initiative that would facilitate reviews of combination products.
If the U.S. FDA has its way, biosimilars and interchangeable biosimilars would no longer be a difference with a distinction – at least when it comes to labeling. Instead of distinguishing between the two, the agency is recommending that the labeling for both follow-ons include a “biosimilarity statement.”
Five years after Gilead Sciences Inc. gave up on momelotinib in the wake of two phase III failures in myelofibrosis, the JAK1/2 and ACVR1 inhibitor has found its way to the market in the hands of GSK plc. Branded Ojjaara, the drug gained U.S. FDA approval for use in intermediate- or high-risk myelofibrosis patients with anemia regardless of prior administration with JAK inhibitors such as Jakafi (ruxolitinib, Incyte Corp.).
Supporting their conclusions with data from the same phase III study, the EMA’s Committee for Medicinal Products for Human Use adopted a positive opinion for extending the use of Oncopeptides AB’s Pepaxti (melflufen) to earlier lines of treating relapsed, refractory multiple myeloma even as the FDA dug in its heels about withdrawing the drug from the U.S. market.
A U.S. FDA advisory committee’s backing keeps Alnylam Pharmaceuticals Inc.’s Onpattro (patisiran) on the road to a supplemental approval in treating a rare heart disease, but it couldn’t stop the company stock from sliding. Shares (NASDAQ:ALNY) closed Sept. 14 down 8.8% at $193.06, the day after the Cardiovascular and Renal Drugs Advisory Committee voted 9-3 that patisiran’s benefits outweigh the risks in treating cardiomyopathy of transthyretin-mediated amyloidosis.
