Pliant Therapeutics Receives FDA Fast Track Designation for the Treatment of Idiopathic Pulmonary Fibrosis
May 03, 2022
SOUTH SAN FRANCISCO, Calif. (GLOBE NEWSWIRE) -- Pliant Therapeutics (NASDAQ: PLRX) announced that PLN-74809, its oral, dual-selective αvß6/αvß1 integrin inhibitor, has received Fast Track designation from the U.S. Food and Drug Administration (FDA) for the potential treatment of idiopathic pulmonary fibrosis (IPF). PLN-74809, the Company’s lead drug candidate, is currently being tested as part of the INTEGRIS-IPF Phase 2a clinical trial (NCT04396756). Pliant anticipates topline data from this randomized, double-blind, placebo-controlled trial in patients with IPF, in mid-2022.
“The Fast Track designation marks an important step in PLN-74809’s clinical development in IPF. It underscores the urgent need for new therapeutic options to address this devastating disease,” said Éric Lefebvre, M.D., Chief Medical Officer at Pliant Therapeutics. “We will continue to work closely with the FDA to support the future development of PLN-74809 beginning with data from the Phase 2a INTEGRIS-IPF trial, which is on track for readout in mid-2022."
FDA’s Fast Track designation is intended to facilitate and expedite the development and review of new drugs to treat serious or life-threatening conditions. To qualify, available clinical and non-clinical data need to demonstrate the potential to address unmet medical need. The benefits of Fast Track designation include opportunities for frequent meetings with the FDA to discuss trial design, development plans and data needed to support drug approval, as well as the ability to submit a New Drug Application (NDA) on a rolling basis, and eligibility for priority review, if relevant criteria are met.
Background on Idiopathic Pulmonary Fibrosis
IPF is a deadly, age-related lung disease of unknown cause with few treatment options. IPF affects approximately 140,000 people in the United States with 30,000 to 40,000 new cases diagnosed each year. Approximately 60 to 80 percent of patients with IPF die within five years of diagnosis. Patients experience debilitating symptoms, including shortness of breath and difficulty performing routine functions, such as walking and talking. Currently, there is no pharmacological cure for IPF with neither of the approved two therapies demonstrating an ability to stop the progression of IPF. Therefore, there is a high unmet need for new therapeutic options to address the symptoms and modify the disease progression of this grievous illness.
