Corsair Pharma, Inc. is a privately held clinical-stage biopharmaceutical company developing proprietary prodrugs of treprostinil for the treatment of pulmonary arterial hypertension (PAH). Its lead program, the TRX-248 transdermal system, is an investigational once-daily patch that delivers an inactive treprostinil prodrug across the skin for conversion to active drug in the liver, aiming to combine the efficacy and titration profile of parenteral prostacyclin therapy with non-invasive once-daily dosing. The company completed its preclinical program, announced positive Phase 1 results for TRX-248 in June 2026, closed a $23M Series B led by New Rhein Healthcare Investors, and has entered a strategic collaboration with United Therapeutics to advance novel treprostinil prodrugs. Corsair Pharma is a drug developer, not a software vendor: its public web presence is a five-page marketing and investor-news site with no developer program, API, SDK, or machine-readable specification of any kind.
