The CRL identified the need for additional information and clarification on chemistry, manufacturing and controls (CMC) data pertaining to the drug product and device biocompatibility. Liquidia does not believe that the items raised in the CRL will be a barrier to the ultimate approval of LIQ861.<\/p>\n<p>The FDA also reconfirmed the need to conduct on-site pre-approval inspections (PAIs) of two of Liquidia\u2019s U.S. manufacturing facilities before the application can be approved. The FDA noted it had been unable to conduct these inspections during the initial review cycle due to COVID-19 related travel restrictions.<\/p>\n<p>The CRL did not cite the need to conduct further clinical studies, nor did the FDA require additional studies related to toxicology or clinical pharmacology. Of note, Liquidia believes that it can address the items raised in the CRL without delaying the otherwise projected launch timing of LIQ861 in the second half of 2022, subject to FDA approval.<\/p>\n<p>\u201cWe remain very confident in LIQ861 and are committed to working closely with the FDA to address these items to support its approval,\u201d said Neal Fowler, Chief Executive Officer at Liquidia. \u201cWith more than 70 patients now having received LIQ861 for more than two years in our clinical trials, Liquidia remains committed to PAH patients who we believe are underserved with currently available treatment options.\u201d<\/p>\n<p>\n        <strong>Webcast and Conference Call<\/strong><br \/>\n        <br \/>Liquidia will host a webcast and conference call\u00a0Wednesday, November 25, 2020\u00a0at 9:00 a.m. ET to discuss this regulatory update for LIQ861.

Liquidia\u00a0believes 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.\u00a0Liquidia\u00a0has 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.<\/p>\n<p>\n        <strong>About PAH<\/strong><br \/>\n        <br \/>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.<\/p>\n<p>\n        <strong>About\u00a0Liquidia<\/strong><br \/>\n        <br \/>Liquidia Technologies, Inc., a wholly owned subsidiary of Liquidia Corporation,\u00a0is a late-stage clinical biopharmaceutical company focused on the development and commercialization of novel products using its proprietary PRINT<sup>\u00ae<\/sup> technology to transform the lives of patients.
