FDA Accepts Biogen’s New Drug Application and Grants Priority Review of Tofersen for a Rare, Genetic Form of ALS
by BPG Blog

CAMBRIDGE, Mass., July 26, 2022 (GLOBE NEWSWIRE) — Biogen Inc. (Nasdaq: BIIB) today announced that the U.S. Food and Drug Administration (FDA) has accepted a New Drug Application (NDA) for tofersen, an investigational drug for superoxide dismutase 1 (SOD1) amyotrophic lateral sclerosis (ALS). The application has been granted priority review and given a Prescription Drug User Fee Act action date of January 25, 2023. The FDA has noted that it is currently planning to hold an Advisory Committee meeting for this application, on a yet-to-be determined date. The average life expectancy for people with ALS is three to five years from time of symptom onset. There is currently no treatment targeted for SOD1-ALS.2  

“The available data show that tofersen has the potential to make a meaningful difference for people with SOD1-ALS,” said Priya Singhal, M.D., M.P.H., Head of Global Safety and Regulatory Sciences and Interim Head of R&D at Biogen. “Pursuing the FDA’s accelerated approval pathway offers the potential to make tofersen available to people living with this fatal, neurodegenerative disease as quickly as possible. If approved, tofersen will be the first treatment to target a genetic cause of ALS and we hope this will pave the way for further advances in this relentless disease.”

Biogen is seeking approval of tofersen under the FDA’s accelerated approval pathway, based on the use of neurofilament as a surrogate biomarker that is reasonably likely to predict clinical benefit. Neurofilaments are normal proteins found in healthy neurons, that are increased in blood and cerebrospinal fluid when damage has been done to neurons or their axons and are a marker of neurodegeneration. In ALS, higher levels of neurofilaments have been found to predict more rapid decline in clinical function and shortened survival.3 Tofersen study results suggest reductions in neurofilament preceded and predicted slowing of decline in measures of clinical and respiratory function, strength, and quality of life. Biogen is committed to ongoing data generation and finalizing the confirmatory data package with the FDA.

FDA, in another test of its flexibility, agrees to review Biogen’s closely watched ALS drug
by BPG Blog

Late last year, Biogen disclosed results from a closely watched study evaluating an experimental drug for Lou Gehrig’s disease, also known as ALS or amyotrophic lateral sclerosis. They showed the drug, called tofersen, wasn’t better than a placebo at slowing progression of the fatal nerve disorder, dealing yet another blow to patients and caregivers, who currently have very limited treatment options.

Despite those results, Biogen recently submitted an approval application to the Food and Drug Administration and on Tuesday, the company announced the agency has agreed to review it on an expedited basis. Biogen had not previously disclosed its submission.

A verdict on approval is expected by Jan. 25, the company said.

The FDA’s decision to review comes a little more than a year after it granted approval to another Biogen drug with a mixed track record in clinical testing. Last June, the drug, which is now sold as Aduhelm, became the first in the U.S. cleared to treat Alzheimer’s disease itself rather than its associated symptoms. While historic, the approval was also exceedingly controversial, and Biogen has since all but scrapped Aduhelm as a product because of challenges getting doctors to prescribe it and insurers to pay for it.
