Biogen Inc.’s problematic trip with Aduhelm (aducanumab-avwa) for Alzheimer’s disease (AD) at last came to an end as the company, probably surprising few on Wall Street, said it’s quitting sales and development of the amyloid-beta directed antibody. The drug won accelerated approval by the U.S. FDA in July 2021. The phase III Envision study with Aduhelm will be stopped, and Cambridge, Mass.-based Biogen chalked a one-time charge of about $60 million related to close-out costs for the program in the fourth quarter of 2023. AD efforts have turned toward Leqembi (lecanemab-irmb), also an amyloid-beta directed antibody.
Biogen Inc. has synthesized non-receptor tyrosine-protein kinase TYK2 inhibitors reported to be useful for the treatment of cancer, autoimmune disease, cardiovascular disorders, fibrosis, inflammatory disorders, liver diseases, pain and neurodegeneration, among others.
In July, Leqembi (lecanemab, Biogen Inc./Eisai Co. Ltd.) became the first amyloid-targeting drug to win traditional approval from the U.S. FDA, after getting accelerated approval in January based on the surrogate endpoint of plaque removal.
Biosimilars grabbed a lot of headlines in 2023, thanks to the biggest U.S. biosimilar launch to date targeting Abbvie Inc.’s mega-blockbuster Humira (adalimumab). Eight biosimilars referencing the immunology drug entered the U.S. market under licensing agreements with Abbvie. Amgen Inc.’s Amjevita led the pack with a five-month headstart in January. The others – including the first adalimumab interchangeable, Boehringer Ingelheim GmbH’s Cyltezo – launched in July.
With Tofidence (tocilizumab-bavi), a monoclonal antibody from Biogen Inc., the U.S. FDA has approved the first biosimilar to the Roche Group AG’s Actemra (tocilizumab), a blockbuster with declining numbers. Tofidence was greenlighted Sept. 29 for treating rheumatoid arthritis in adults, and for treating polyarticular and systemic juvenile idiopathic arthritis in those ages 2 and older. It’s also the first biosimilar approved to treat systemic juvenile idiopathic arthritis.
Thanks to a raft of new approvals by Japan’s Ministry of Health, Labor and Welfare (MHLW), patients in Japan will soon have access to Biogen Inc./Eisai Co. Ltd.’s Leqembi (lecanemab), an amyloid-beta binder, for slowing progression of mild cognitive impairment and mild dementia due to Alzheimer's disease.
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.
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).
Biogen Inc. has synthesized 3-β-hydroxysteroid-δ(8),δ(7)-isomerase (EBP) inhibitors reported to be useful for the treatment of multiple sclerosis (MS).
