Pliant Therapeutics, Inc. (Nasdaq: PLRX), a clinical stage biopharmaceutical company focused on discovering and developing novel therapies for the treatment of fibrosis, today announced a positive safety review of the ongoing INTEGRIS-IPF Phase 2a trial of PLN-74809 at 320 mg once-daily dose in patients with idiopathic pulmonary fibrosis (IPF) from a regularly scheduled meeting of its independent Data Safety Monitoring Board (DSMB).
Recent independent Data Safety Monitoring Board (DSMB) review recommended the INTEGRIS-IPF Phase 2a trial continue without modification
Interim 12-week data expected in early 2023
SOUTH SAN FRANCISCO, Calif., Sept. 01, 2022 (GLOBE NEWSWIRE) -- Pliant Therapeutics, Inc., (Nasdaq: PLRX), a clinical stage biopharmaceutical company focused on discovering and developing novel therapies for the treatment of fibrosis, today announced a positive safety review of the ongoing INTEGRIS-IPF Phase 2a trial of PLN-74809 at 320 mg once-daily dose in patients with idiopathic pulmonary fibrosis (IPF) from a regularly scheduled meeting of its independent Data Safety Monitoring Board (DSMB). The DSMB recommended the INTEGRIS-IPF trial continue without modification.
The DSMB review was held after completion of enrollment of the 320 mg cohort of the INTEGRIS-IPF trial and examined the safety data from all patients enrolled, approximately half of whom had completed at least 12 weeks of treatment. Interim 12-week data from the 320 mg dose cohort from this Phase 2a, randomized, double-blind, placebo-controlled trial are expected in early 2023.
“This positive safety review marks an important milestone in the development of PLN-74809. Given 320 mg is the highest dose planned to be tested in the PLN-74809 program, the positive DSMB review significantly builds on the favorable safety profile seen to date,” said Éric Lefebvre, M.D., Chief Medical Offer at Pliant. “In addition to the accumulating patient safety database, we have completed all necessary sub-chronic and chronic GLP toxicology studies of PLN-74809, with no on-target or off-target safety concerns noted to date across all doses tested.”
PLN-74809, is an oral, small molecule, dual-selective inhibitor of αvβ6 and αvβ1 being developed for the treatment of IPF and primary sclerosing cholangitis (PSC). PLN-74809 has been administered to over 450 study participants, including healthy volunteers and patients, with no drug-related serious adverse events or drug-related severe adverse advents reported to date.
About the INTEGRIS-IPF Trial
INTEGRIS-IPF is a randomized, double-blind, placebo-controlled study evaluating PLN-74809 at once-daily doses across multiple doses. The current patient cohort is testing 320 mg of PLN-74809 administered daily over at least six months, and up to 48 weeks, in approximately 28 patients with IPF (NCT04396756). The primary endpoint is the evaluation of PLN-74809 safety and tolerability. The secondary endpoint is the assessment of pharmacokinetics. Exploratory endpoints will measure change in forced vital capacity (FVC), HRCT-based Quantitative Lung Fibrosis score (QLF), and selected biomarkers over 6 months of treatment. In July, Pliant announced positive topline data from the INTEGRIS-IPF trial of 40 mg, 80 mg and 160 mg 12-week dose cohorts.
