    Liquidia Surpasses 5,000 Yutrepia Patients as United Therapeutics Patent Fight Continues

    Question

    Liquidia Surpasses 5,000 Yutrepia Patients as United Therapeutics Patent Fight Continues

    Direct answer

    Liquidia Corporation reported significant patient uptake for its dry powder formulation Yutrepia, crossing 5,000 initiated patients as of July 2026. The therapy competes directly with United Therapeutics' established inhaled treprostinil product line in pulmonary arterial hypertension. Despite commercial gains, Liquidia stock declined 13.9% over the past month as investors weigh substantial R&D outlays and single-drug concentration against ongoing patent litigation from United Therapeutics that could impact commercial supply continuity.
