BioCryst Pharmaceuticals Inc. on Wednesday said the U.S. Food and Drug Administration granted orphan-drug designation to BCX9250 for the treatment of fibrodysplasia ossificans progressiva, an ultra-rare genetic disorder.

The Durham, N.C., pharmaceutical company said it aims to begin studies of the ALK-2 inhibitor in patients next year.

The FDA's orphan-drug program gives special status to drugs and biologics for diseases and disorders that affect fewer than 200,000 people in the U.S. and provides for an extended marketing exclusivity period against competition.

Fibrodysplasia ossificans progressiva is a severely disabling disorder characterized by the irregular formation of bone outside the normal skeleton.
