YUTREPIA, enabled by Liquidia Corporation (NASDAQ:LQDA)’s proprietary PRINT technology, is the first and only prostacyclin dry-powder formulation designed for deep-lung delivery using a low-effort, portable inhalation device. The approval is based on results from the Phase 3 INSPIRE trial, which showed YUTREPIA to be safe and well-tolerated, offering a new treatment option for over 105,000 U.S. patients suffering from PAH and PH-ILD.

Liquidia Corporation (NASDAQ:LQDA)’s commercial team is preparing to launch YUTREPIA, aiming to improve exercise ability and quality of life for patients. However, United Therapeutics Corporation has filed a patent infringement lawsuit and is seeking a court order to block YUTREPIA’s commercial launch, with a decision on the injunction still pending.
