The biotech segment strengthened after Sarepta gained approval for the first therapy for Duchenne muscular dystrophy, a genetic disease that mainly affects young boys. The FDA approved the drug under its “accelerated approval” program, which can make the drugs available for sale if there are signs of improvements among patients while more study is conducted, reports Anna Edney for Bloomberg.

“Accelerated approval makes this drug available to patients based on initial data, but we eagerly await learning more about the efficacy of this drug through a confirmatory clinical trial that the company must conduct after approval,” Janet Woodcock, director of the FDA’s Center for Drug Evaluation and Research, said in a statement.
