Agency approved treatments via policies that allow drugs to be brought to market faster under certain circumstances Before there was conclusive proof that it works. Biogen needs to provide corroborative evidence from ongoing clinical studies to keep medicines on the market.
The decision marks the first conditional approval given to a drug to treat ALS, or amyotrophic lateral sclerosis, which commonly causes paralysis and death within a few years. Fewer than half of patients eligible for Qalsody survive three years or more after diagnosis.
