United Therapeutics announced the United States Food and Drug Administration (FDA) has granted orphan drug designation to treprostinil for the treatment of patients with idiopathic pulmonary fibrosis (IPF).
It took Novartis' Sandoz years to reach the market with a generic to United Therapeutics’ pulmonary arterial hypertension drug Remodulin, but last month, the company managed to do just that.
US-based biopharmaceutical company MannKind has entered an exclusive licensing and collaboration agreement with United Therapeutics over a dry powder formulation of treprostinil.
