MONDAY, June 13, 2022 (HealthDay News) — An experimental drug for amyotrophic lateral sclerosis (ALS) was approved in Canada on Monday, but an ongoing evaluation of the treatment by the U.S. Food and Drug Administration has raised questions about its effectiveness.
A condition of the Health Canada approval of Albrioza (AMX0035) calls for Massachusetts-based drug maker Amylyx Pharmaceuticals to later provide better evidence that the treatment is effective. That includes verifying the “clinical benefit of this drug” with data from an ongoing phase 3 clinical trial expected to conclude in 2024, additional pharmacological studies, and periodic safety reports.
“For nearly a decade, we have been committed to creating more meaningful moments for people living with ALS and their families. We are excited with Health Canada’s decision to approve Albrioza with conditions. Albrioza is a therapy that demonstrated … a statistically significant and clinically meaningful impact on function, alone or in addition to existing ALS therapies,” Justin Klee and Joshua Cohen, co-CEOs and cofounders of Amylyx, said in a company statement.
Earlier this year, an FDA review of the drug said it was safe, but there was insufficient evidence that it helped patients live longer or slowed their loss of crucial functions such as muscle control, speaking, or breathing without assistance, The New York Times reported. In a close vote in March, an independent panel of advisers to the FDA concluded that Albrioza was not ready for approval by the agency. The FDA recently extended its deadline for a final decision to Sept. 29 to review additional data from Amylyx.
Last month, 38 U.S. doctors who treat ALS patients sent a letter to the FDA urging the agency to approve the drug. In recent weeks, a campaign for approval of the drug has generated more than 6,000 emails asking the FDA to approve the drug, according to the ALS Association. Amylyx bankrolled most of its research on Albrioza, but the ALS Association contributed $2.2 million raised through the 2014 Ice Bucket Challenge.
Angela Genge, M.D., director of the ALS Global Centre for Excellence at the Montreal Neurological Institute, who has received fees from Amylyx for serving on an advisory board, said American patients would be legally able to receive Albrioza in Canada if it were prescribed by a Canadian physician and obtained from a Canadian pharmacy. However, they would not be eligible for insurance coverage under Canada’s public or private system. Amylyx has not yet disclosed a price for Albrioza, The Times reported.
