The U.S. FDA’s accelerated approval path is front burner these days, what with Congress looking to modernize the path through provisions added to the must-pass user fee legislation, the controversy still boiling over the FDA’s accelerated approval last year of Biogen Inc.’s Alzheimer’s drug, Aduhelm (aducanumab), and a number of recent withdrawals of drugs granted accelerated approval years ago.
Following a negative phase II/III study of an investigational treatment for major depressive disorder, Praxis Precision Medicines Inc. is dropping staff from the payroll and refocusing the company’s resources on tremor and epilepsy. The Aria study of PRAX-114, a positive allosteric modulator extrasynaptic GABA receptor, missed its primary endpoint, statistical significance as measured on the Hamilton Depression Rating Scale. It also missed the study’s secondary endpoints.
Pivotal in killing the Biden administration’s Build Back Better budget legislation, Sen. Joe Manchin (D-W.Va.) is now working to revive parts of it, including the provision that would require Medicare to directly negotiate prescription drug prices.
The flop that is Aduhelm (aducanumab) made itself felt in Biogen Inc.’s executive suite as CEO Michael Vounatsos is leaving the company. He had the job for five and a half years and for less than a year after the controversial Alzheimer’s treatment was approved. He will stick around until a successor is found.
The U.S. Centers for Medicare & Medicaid Services’ (CMS) decision last month restricting coverage of a class of Alzheimer’s drugs to clinical trials meeting the agency’s standards still isn’t sitting well with some lawmakers.
Making his first in-person appearance April 27 before the House Energy and Commerce Subcommittee on Health, U.S. Health and Human Services Secretary Xavier Becerra was prepared to answer questions about President Joe Biden’s fiscal 2023 budget that would increase HHS’ discretionary budget to $127 billion, nearly a 27% increase over the 2021 enacted level.
The release by the U.S. CMS of the final national coverage determination (NCD) for Biogen Inc.’s Alzheimer disease (AD) drug, Aduhelm (aducanumab), lit speculation on the meaning for others in the space. CMS is “still being conservative,” said Howard Fillit, co-founder and chief science officer of the Alzheimer’s Drug Discovery Foundation (ADDF). “We’re in a new era. It’s unprecedented that Medicare doesn’t pay for a drug that received approval from the FDA,” even though it was not a full but an accelerated clearance.
After hitting a low in late February, BioWorld’s Neurological Diseases Index is rebounding, although it is still down by 8.9% this year, following the same path of the broader markets.
Following another failure in amyotrophic lateral sclerosis (ALS), Biogen Inc. will discontinue its development of antisense oligonucleotide BIIB-078 with partner Ionis Pharmaceuticals Inc. The stumble is part of a mega-collaboration the two companies began 10 years ago that has also yielded a lot of success, including the blockbuster Spinraza (nusinersen).
The potholes in the U.S. FDA’s accelerated approval path could be paved over by a bill introduced in Congress this week. Rep. Frank Pallone (D-N.J.), chair of the House Energy and Commerce Committee, introduced the Accelerated Approval Integrity Act March 8 to keep the path open to innovative drugs where there is unmet need while streamlining the process for taking drugs off the market when they don’t prove clinical benefit in a timely manner.
