The company had hoped to persuade the FDA to accept an accelerated approval filing for Raxone based on a single, already completed phase III study -- but the FDA turned them down. Santhera shares fell 38% following the news.

Santhera is developing Raxone to improve the lung function of Duchenne patients.
