    Liquidia Surpasses 5,000 Yutrepia Patients as United Therapeutics Patent Litigation Lingers

    Question

    Liquidia Surpasses 5,000 Yutrepia Patients as United Therapeutics Patent Litigation Lingers

    Direct answer

    Liquidia has reached over 5,000 commercial patient starts for Yutrepia as of July 2026, demonstrating clinical adoption in pulmonary arterial hypertension. However, the company remains locked in patent litigation with incumbent United Therapeutics, creating regulatory and commercialization headwinds. The unresolved legal outcome alongside elevated R&D outlays has driven a 13.9% monthly decline in LQDA valuation.
