About L606 (treprostinil liposome inhalation suspension)
L606 is an investigational, sustained-release formulation of treprostinil administered twice daily through rapid nebulization with a hand-held portable system. The L606 suspension uses Pharmosa Biopharm’s proprietary liposomal formulation to encapsulate treprostinil which can be released slowly at a controlled rate into the lung, enhancing drug exposure over an extended period of time. L606 is currently being evaluated in an open-label study in the United States for treatment of pulmonary arterial hypertension (PAH) and pulmonary hypertension associated with interstitial lung disease (PH-ILD) with a planned global, pivotal, randomized, placebo-controlled study for the treatment of PH-ILD.

About YUTREPIA™ (treprostinil) Inhalation Powder
YUTREPIA is an inhaled dry-powder formulation of treprostinil delivered through a convenient, low-effort, palm-sized device. YUTREPIA is indicated for the treatment of pulmonary arterial hypertension (PAH) and pulmonary hypertension associated with interstitial lung disease (PH-ILD) to improve exercise ability. YUTREPIA was designed using Liquidia’s PRINT® technology, which enables the development of drug particles that are precise and uniform in size, shape and composition, and that are engineered for enhanced deposition in the lung following oral inhalation. YUTREPIA was previously referred to as LIQ861 in investigational studies.
