Fourth Quarter and Recent Highlights

Bexotegrast Highlights

  • Positive safety and efficacy data from 320 mg dose cohort of INTEGRIS-PSC Phase 2a trial in patients with primary sclerosing cholangitis (PSC). At a once-daily dose of 320 mg, bexotegrast was well tolerated over 12 weeks of treatment with no drug-related severe or serious adverse events. At the 320 mg dose, bexotegrast reduced both Enhanced Liver Fibrosis (ELF) scores and PRO-C3 levels and showed improvements in hepatocyte function and bile flow by contrast MRI imaging relative to placebo at Week 12. Twenty-four-week data from the 320 mg dose group is expected in mid-2024.
  • Enrollment continues in BEACON-IPF, a Phase 2b trial of bexotegrast in patients with idiopathic pulmonary fibrosis (IPF). 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. BEACON-IPF is expected to enroll approximately 270 patients with IPF.

Pipeline Programs

  • Phase 1 trial of PLN-101095 in solid tumors is enrolling. 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 third 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. Preliminary data is expected in late 2024.
  • Muscular dystrophy program on track for regulatory filing in the first quarter of 2024. PLN-101325 is a monoclonal antibody designed to act as an allosteric agonist of integrin α7β1. Filing for first-in-human clinical studies in Duchenne muscular dystrophy (DMD) is expected in the first quarter of 2024.

Fourth Quarter 2023 Financial Results

  • Research and development expenses were $33.2 million, as compared to $25.1 million for the prior-year quarter. The increase was due primarily to higher employee-related expenses and increased clinical and manufacturing-related costs associated with our lead program, bexotegrast.
  • General and administrative expenses were $13.9 million, as compared to $14.3 million for the prior-year quarter. The decrease was primarily due to a decrease in stock-based compensation as we achieved a clinical development milestone in the fourth quarter of 2022 that triggered the vesting of certain performance based awards.
  • Net loss was $41.1 million as compared to $35.1 million for the prior-year quarter. The increase was due to higher operating expenses coupled with a decrease in collaboration revenues under the Novartis collaboration during the quarter.
  • As of December 31, 2023, the Company had cash, cash equivalents and short-term investments of $495.7 million which the Company expects, together with funds available under the Oxford Loan Agreement, to be sufficient to fund operations into the second half of 2026.
