First Quarter and Recent Developments

Bexotegrast Highlights

• BEACON-IPF close-out activities continue with topline data expected in the second quarter of 2025. Following the termination of the BEACON-IPF Phase 2b/3 trial evaluating bexotegrast in patients with idiopathic pulmonary fibrosis (IPF), the Company continues the formal close out of the global trial. Topline data from the BEACON-IPF trial is expected in the second quarter of 2025.
• Results from a Phase 2a positron emission tomography (PET) imaging trial published in the American Journal of Respiratory and Critical Care Medicine (AJRCCM). The reviews the previously reported positive results from the first interventional, single-center double-blind, placebo-controlled Phase 2 trial of bexotegrast using PET and magnetic resonance imaging to evaluate collagen deposition in the lungs of 10 patients with IPF.
  
  
  
  

Oncology Program

• Interim Phase 1 data from a trial of PLN-101095 and pembrolizumab demonstrated antitumor activity with confirmed partial responses in three of six patients treated with the highest dose tested to date. Topline data from the first three cohorts of the ongoing Phase 1 dose escalation trial of PLN-101095 in combination with pembrolizumab showed confirmed partial responses in solid tumors that are resistant to immune checkpoint inhibitors. Of the six patients treated at the 1000 mg dose administered orally twice daily (BID), three patients, suffering from non-small cell lung cancer (NSCLC), cholangiocarcinoma and melanoma, experienced confirmed partial response assessed by iRECIST criteria associated with 74%, 48% and 42% reductions in tumor size, respectively. PLN-101095 was generally well tolerated across all doses tested. The trial is currently enrolling the fourth of five potential cohorts, evaluating PLN-101095 at 1000 mg administered three times daily (TID).

First Quarter 2025 Financial Results

• Research and development expenses were $43.4 million, as compared to $37.1 million for the prior-year quarter. The increase was primarily due to acceleration of close-out activities for BEACON-IPF, a Phase 2b/3 study of bexotegrast and employee-related expenses, driven by increased headcount.
• General and administrative expenses were $15.5 million, as compared to $15.2 million for the prior-year quarter. The increase was primarily due to professional service expenses.
• Net loss of $56.2 million as compared to $47.0 million for the prior-year quarter. The increase was primarily due to higher operating expenses driven by close-out activities related to BEACON-IPF.
• As of March 31, 2025, the Company had cash, cash equivalents and short-term investments of $307.1 million.
