District Court Dismisses Dispute Filed by United Therapeutics Against Liquidia

MORRISVILLE, N.C., May 02, 2025 (GLOBE NEWSWIRE) -- Liquidia Corporation (NASDAQ: LQDA), a biopharmaceutical company developing innovative therapies for patients with rare cardiopulmonary disease, today announced that Judge Kelly of the U.S. District Court for the District of Columbia (District Court) dismissed, without prejudice, the cross-claim filed by United Therapeutics (UTHR) that sought to challenge Liquidia’s amendment to its New Drug Application (NDA) for YUTREPIA™ (treprostinil) inhalation powder, which added the treatment of pulmonary hypertension associated with interstitial lung disease (PH-ILD) to the proposed label for YUTREPIA. In its ruling, the District Court determined that UTHR’s claim was unripe and that UTHR had failed to plausibly allege that it has standing.
