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

May 10, 2021

MORRISVILLE, N.C., May 10, 2021 (GLOBE NEWSWIRE) -- Liquidia Corporation (NASDAQ: LQDA) announced today that on May 7, 2021, it resubmitted its New Drug Application (NDA) for LIQ861 for the treatment of pulmonary arterial hypertension (PAH). The U.S. Food and Drug Administration (FDA) issued a Complete Response Letter (CRL) regarding the NDA in November 2020 indicating that the application was incomplete and not ready for approval in its present form. Liquidia and the FDA held a Type A meeting in January 2021 to discuss the CRL and the requirements for the NDA resubmission.

The resubmitted NDA includes additional information and clarification on chemistry, manufacturing, and controls (CMC) pertaining to the drug product as well as data on device biocompatibility. No additional data from clinical trials or studies related to toxicology or clinical pharmacology was required. The Company anticipates that the FDA will classify the resubmitted NDA, if accepted, as a Class 2 Resubmission, which would result in a six-month review cycle from the date of resubmission.

In addition to the items identified in the CRL, the FDA also confirmed the need to conduct on-site pre-approval inspections. The FDA noted it had been unable to conduct these inspections in 2020 during the initial review cycle due to COVID-19 related travel restrictions. The company remains prepared to conduct these inspections at any time.

Damian deGoa, Chief Executive Officer of Liquidia, said: “The team has worked hard to provide a comprehensive and rapid response to the CRL. We look forward to working with the FDA through the review process during the coming months.”
