## What Liquidia does

Liquidia is a biopharmaceutical company focused on respiratory and vascular diseases, including pulmonary arterial hypertension (PAH) and pulmonary hypertension associated with interstitial lung disease (PH-ILD). Its revenue comes from YUTREPIA (treprostinil) inhalation powder, which the text says the FDA approved in May 2025 for PAH and PH-ILD, with commercialization beginning in June 2025. YUTREPIA is a dry powder made with the company's proprietary PRINT technology and is delivered with a dry-powder inhaler. The company also shares profit under a promotion agreement with Sandoz for Sandoz's generic treprostinil injection in the United States. Its investigational product L606, a liposomal formulation of treprostinil licensed from Pharmosa Biopharm, is given twice daily with a next-generation nebulizer. L606 is in an open-label study for PAH and PH-ILD in the United States, and the company has initiated a worldwide, placebo-controlled pivotal study for PH-ILD. The company also plans clinical studies of YUTREPIA for pulmonary hypertension associated with COPD, idiopathic pulmonary fibrosis, progressive pulmonary fibrosis and Raynaud's phenomenon associated with systemic sclerosis.

| Product or program | What it is | Stage |
|---|---|---|
| YUTREPIA | Inhaled dry powder treprostinil for PAH and PH-ILD | approved |
| L606 | Investigational liposomal treprostinil given twice daily by nebulizer | pivotal study |
| Treprostinil Injection | Generic treprostinil injection sold in the US under a Sandoz promotion agreement |  |
