(Nasdaq: PLRX), a clinical stage biopharmaceutical company focused on discovering and developing novel therapies for the treatment of fibrosis, today announced that, following a positive independent Data Safety Monitoring Board (DSMB) safety review, enrollment has commenced in a Phase 2a trial of PLN-74809 at 320 mg dosed once daily for at least six months in patients with idiopathic pulmonary fibrosis (IPF). 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. “We are pleased that the favorable safety and tolerability profile seen with PLN-74809 to date supports the advancement of our Phase 2a program to evaluate a higher dose at a longer treatment duration,” said Bernard Coulie M.D. Ph.D., President and CEO of Pliant. “It is noteworthy that our sub-chronic and chronic GLP toxicology studies have revealed no on-target or off-target safety concerns across all doses tested.

The primary endpoint is the evaluation of PLN-74809 safety and tolerability and 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. This trial is leveraging the same sites and protocol as the INTEGRIS-IPF...
