Sanofi SA said Wednesday that the U.S. Food and Drug Administration has granted breakthrough therapy designation to hemophilia A drug efanesoctocog alfa, a move meant to expedite the development and review of drugs that address serious illnesses.

The designation is based on positive trial results that show the drug's ability to prevent bleeds and superiority in preventing them compared with previous treatments. The Phase 3 trial in question, named XTEND-1, has met its primary endpoint of showing a clinically meaningful prevention of bleeds, the company said.

Hemophilia is a condition targeting males especially, in which the ability for blood to coagulate is impaired, leading to abnormal bleeding.
