RESEARCH TRIANGLE PARK, N.C., Jan. 27, 2020 (GLOBE NEWSWIRE) — Liquidia Technologies, Inc. (Nasdaq:LQDA) (“Liquidia”), a late-stage clinical biopharmaceutical company focused on the development of products using its proprietary PRINT® technology, today announced the submission of its New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for LIQ861. LIQ861 is an investigational, inhaled dry powder formulation of treprostinil designed using Liquidia’s PRINT® technology with the goal of enhancing deep-lung delivery using a convenient, palm-sized dry powder inhaler for the treatment of pulmonary arterial hypertension (PAH).
The NDA has been 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. The open-label Phase 3 study, known as INSPIRE (Investigation of the Safety and Pharmacology of Dry Powder Inhalation of Treprostinil) (NCT03399604), included 121 PAH patients who transitioned from stable doses of the reference listed drug or added LIQ861 to no more than two approved non-prostacyclin oral PAH therapies. The company also completed pharmacokinetic studies to establish the bioavailability of LIQ861 relative to the bioavailability of the reference listed drug.
Neal Fowler, Chief Executive Officer of Liquidia, said, “The submission of the NDA for LIQ861 in the U.S. is a significant milestone for our company and our goal to address an important unmet need in the delivery of inhaled therapy for PAH patients. We would like to sincerely thank the patients, their families and the clinical investigators for their participation in the LIQ861 clinical program, and we look forward to working closely with the FDA during the review process.”
About LIQ861
LIQ861 is an investigational inhaled dry powder formulation of treprostinil designed using Liquidia’s PRINT® technology with the goal of enhancing deep-lung delivery using a convenient, palm-sized dry powder inhaler (“DPI”) for the treatment of pulmonary arterial hypertension (PAH). PRINT® technology enables development of drug particles that are precise and uniform in size, shape, weight and composition that are engineered for optimal deposition in the lung following oral inhalation. Liquidia believes LIQ861 can overcome the limitations of current inhaled therapies and has the potential to maximize the therapeutic benefits of treprostinil in treating PAH by safely delivering higher doses into the lungs. Liquidia has completed an open-label, multi-center phase 3 clinical study of LIQ861 in patients diagnosed with PAH known as INSPIRE, or Investigation of the Safety and Pharmacology of Dry Powder Inhalation of Treprostinil.
About Liquidia
Liquidia is a late-stage clinical biopharmaceutical company focused on the development and commercialization of therapeutics using its proprietary PRINT® technology to transform the lives of patients. Currently, Liquidia is focused on the development of two product candidates using its PRINT particle engineering platform: LIQ861 for the treatment of pulmonary arterial hypertension and LIQ865 for the treatment of local post-operative pain. Having been evaluated in a phase 3 clinical trial (INSPIRE), LIQ861 is designed to improve the therapeutic profile of treprostinil with the goal of enhancing deep-lung delivery and achieving higher dose levels than current inhaled therapies by using a convenient, palm-sized dry powder inhaler. LIQ865, for which Liquidia has completed two phase 1 clinical trials, is designed to deliver sustained-release particles of bupivacaine, a non-opioid anesthetic, to treat local post-operative pain for three to five days through a single administration.
