Soligenix shares jumped after the company announced that the U.S. Food and Drug Administration (FDA) had granted orphan drug designation to dusquetide, the active ingredient in SGX945, for the “treatment of Behcet’s Disease.” The company recently announced positive data from its Phase 2a proof-of-concept study for SGX945.
