Liquidia Announces FDA Acceptance of New Drug Application for LIQ861 (treprostinil) Inhalation Powder for the Treatment of Pulmonary Arterial Hypertension

RESEARCH TRIANGLE PARK, N.C., April 08, 2020 (GLOBE NEWSWIRE) — Liquidia Technologies, Inc. (Nasdaq: LQDA), a late-stage clinical biopharmaceutical company focused on the development and commercialization of novel products utilizing its proprietary PRINT® technology, today announced that the U.S. Food and Drug Administration (FDA) accepted for review the Company’s New Drug Application (NDA) seeking marketing approval for LIQ861 for the treatment of pulmonary arterial hypertension (PAH). Under the Prescription Drug User Fee Act (PDUFA), the FDA has set a goal date of November 24, 2020.

LIQ861 is an investigational, inhaled dry powder formulation of treprostinil designed using the Company’s novel PRINT technology and engineered with the goal of enhancing deep-lung delivery of treprostinil in PAH patients by means of a convenient, palm-sized dry powder inhaler. The NDA was submitted under the 505(b)(2) regulatory pathway and includes data from three clinical studies to establish the safety, tolerability and pharmacokinetic profile of LIQ861.

“FDA acceptance of this NDA is a significant milestone for our company and our PRINT technology. PRINT was the cornerstone that allowed for the precise engineering and development of LIQ861 into its current form and serves as the foundation for all of our products in development,” said Neal Fowler, Chief Executive Officer of Liquidia. “If approved, LIQ861 will represent an important step forward in addressing the unmet needs of PAH patients by providing a convenient alternative to existing therapies. We look forward to working closely with the FDA through the NDA review process.”

About PAH
PAH is a chronic, progressive disease caused by the hardening and narrowing of the pulmonary arteries that can lead to right heart failure and eventually death. Treprostinil is a synthetic analog of prostacyclin, a vasoactive mediator essential to normal lung function that is deficient in patients with PAH. PAH is a rare disease, with an estimated prevalence in the United States of approximately 30,000 patients. The exact cause of PAH is often unknown and, although the symptoms are treatable, there is no known cure for the disease.
