Biogen's ALS drug wins key support
Biogen's treatment for a rare, genetic form of ALS won over a panel of FDA advisers, who voted in favor of its conditional approval despite unanswered questions about its benefit to patients.
The panel voted 9-0 that the "totality of the evidence" was enough to support accelerated approval for Biogen's treatment, called tofersen. The same experts voted 3-5 (with one abstention) that the tofersen data, including from a failed clinical trial, were not sufficiently convincing to support full approval.
In a day-long discussion of Biogen's application, the panelists struggled with how to balance tofersen's uncertain supporting evidence with the devastating and life-threatening effects of its target disease. The drug is meant to treat an inherited form of ALS caused by a mutation in a gene called SOD1, which accounts for just 2% of the overall cases of the disease.

89bio's NASH drug hits its mark
An experimental treatment from 89bio improved liver scarring at more than three times the rate of placebo without worsening other symptoms of patients with the fatty liver disease known as NASH, the company said yesterday.
As STAT's Adam Feuerstein reports, 89bio's drug met the main goal of a mid-stage clinical trial, offering the potential for less frequent injections than a similar experimental treatment being developed by Akero Therapeutics, a competing drugmaker.
NASH, short for non-alcoholic steatohepatitis, is a widespread chronic disease in which fat accumulates in the liver. While there are no medicines yet approved for NASH, an increasing number of companies are pressing forward with potential treatments, including Intercept Pharmaceuticals, Novo Nordisk, and Madrigal Pharmaceuticals.
