Fourth Quarter and Recent Highlights
Bexotegrast Highlights
•BEACON-IPF discontinued following recommendation from expanded data safety monitoring board (DSMB). Following a prespecified data review and recommendation by the trial’s independent DSMB, as well as a secondary review and recommendation by an outside expert panel, Pliant has discontinued the BEACON-IPF Phase 2b trial. While an imbalance in unadjudicated IPF-related adverse events between the treatment and placebo groups led to the discontinuation of the trial, early evidence of efficacy on the forced vital capacity (FVC) endpoint was also observed. The Company plans to analyze the complete data from the BEACON-IPF trial and evaluate next steps for bexotegrast’s development. BEACON-IPF is a 52-week, multinational, randomized, dose-ranging, double-blind, placebo-controlled trial evaluating bexotegrast at once-daily doses of 160 mg or 320 mg in patients with idiopathic pulmonary fibrosis (IPF).
Oncology Program
•Phase 1 trial of PLN-101095 in solid tumors continues to enroll, with interim data expected in the first quarter 2025. This is a Phase 1 open label trial of PLN-101095, an oral, small molecule, dual selective inhibitor of αvβ8 and αvβ1 integrins designed to block TGF-β activation in the tumor microenvironment. The trial is currently dosing the fourth of five planned dose cohorts in a Phase 1 open label dose-escalation trial of PLN-101095 as monotherapy and in combination with pembrolizumab in patients with solid tumors that are resistant to immune checkpoint inhibitors. Interim data from the first three cohorts is expected in the first quarter of 2025.
Neuromuscular Program
•PLN-101325 for treatment of muscular dystrophies. PLN-101325 is a monoclonal antibody that acts as an allosteric agonist of integrin α7β1, currently in development for treatment of muscular dystrophies. PLN-101325 is Phase 1 ready with clinical trial approval (CTA) open in Australia.
Corporate Highlights
•Appointment of Delphine Imbert, Ph.D. as Chief Technical Officer. Dr. Imbert brings 25 years of product development, process optimization and manufacturing experience across multiple drug modalities. Most recently, Dr. Imbert served as Senior Vice President of CMC and Technical Operations at Chinook Therapeutics.
Fourth Quarter 2024 Financial Results
•Research and development expenses were $38.8 million, as compared to $33.2 million for the prior-year quarter. The increase was primarily due to costs associated with the BEACON-IPF Phase 2b/3 clinical trial.
•General and administrative expenses were $14.5 million, as compared to $13.9 million for the prior-year quarter. The increase was primarily due to employee-related expenses driven by increased headcount over prior year.
•Net loss was $49.7 million as compared to $41.1 million for the prior-year quarter. The increase was due to higher operating expenses primarily attributable to costs associated with the BEACON-IPF Phase 2b/3 clinical trial and reduced interest income on short-term investments.
•As of December 31, 2024, the Company had cash, cash equivalents, restricted cash and short-term investments of $357.2 million which the Company expects to be sufficient to fund operations for the next 12 months and beyond.
