Now that the U.S. FDA has nearly 15 years of experience with developing and implementing a biosimilar pathway, it’s time for that regulatory path to catch up with the science, according to experts that have been involved in biosimilar development even before Congress passed the Biologics Price Competition and Innovation Act that created the framework for the U.S. biosimilar market.
After hitting the safety and efficacy endpoints in a pivotal study of wet age-related macular degeneration (AMD), Outlook Therapeutics Inc.’s CEO said he had not expected to receive a complete response letter (CRL) from the U.S. FDA. The BLA for ONS-5010 (bevacizumab-vikg) now is on hold, the company said, because the agency said chemistry, manufacturing, and controls management problems were getting in the way, along with “open observations from pre-approval manufacturing inspections, and a lack of substantial evidence.”
The U.S. FDA has awarded Bristol Myers Squibb Co. (BMS) with its third approval for treating anemia with Reblozyl (luspatercept-aamt). Specifically, the approval is for treating anemia without previous erythropoiesis stimulating agent use in adults with very low- to intermediate-risk myelodysplastic syndromes who may require regular red blood cell transfusions.
Biosimilars continue to pose cheaper alternatives to their established, blockbuster counterparts. The U.S. FDA has approved Tyruko (natalizumab-sztn) from Sandoz Inc., the generics business of Novartis AG. It is the first approved biosimilar to Biogen Inc.’s blockbuster Tysabri (natalizumab), an injectable monoclonal antibody for treating adults with relapsing forms of multiple sclerosis (MS).
Shares of Fulcrum Therapeutics Inc. shot up 38.5% on Aug. 22 following news that the U.S. FDA had lifted the clinical hold on the company’s phase Ib sickle cell disease candidate, FTX-6058.
The U.S. FDA approved Pfizer Inc.’s respiratory syncytial virus (RSV) prophylactic, Abrysvo (RSVpreF) for maternal use, providing pregnant women with the option of protecting their newborns up to the age of 6 months against RSV for the first time. The regulator’s Vaccines and Related Biological Products Advisory Committee voted 14-0 in favor of approving the BLA for maternal use of the vaccine in May, a few weeks before the agency gave it the go-ahead for use in older adults (those ages 60 and older).
The U.S. FDA is in the midst of a shake-up of several major offices, including the Office of Regulatory Affairs, but its commissioner, Robert Califf, believes there are even greater issues faced by the agency. Califf said during an Aug. 22 public forum that prices for generic drugs are too low to encourage manufacturers to continue to produce these products, adding that the issue is sufficiently severe to constitute a national security risk.
The impact of a black box warning on Neurocrine Biosciences Inc.’s expanded U.S. label for Ingrezza (valbenazine) to treat chorea associated with Huntington’s disease (HD) appears up for debate, following FDA approval late Aug. 18. But analysts agree that it is unlikely to affect sales of the VMAT2 inhibitor in tardive dyskinesia, for which the company recently raised 2023 guidance as high as $1.82 billion.
On the heels of the U.S. FDA clearance for Veopoz (pozelimab-bbfg) from Regeneron Pharmaceuticals Inc. to treat Chaple disease, the regulatory rollercoaster ride for the firm’s bid with higher-dose Eylea (aflibercept) ended with a green light for that compound as well. Eylea HD is indicated for wet age-related macular degeneration, diabetic macular edema, and diabetic retinopathy.
The U.S. FDA has approved its second treatment for an ultra-rare disease in the past three days by greenlighting Veopoz (pozelimab-bbfg) from Regeneron Pharmaceuticals Inc. Approval of the priority BLA for Veopoz, a fully human monoclonal antibody to treat Chaple disease, was announced two days ahead of its Aug. 20 PDUFA date. It is the only FDA-approved therapy for the indication.
