Aileron Therapeutics, Inc. ("Aileron") (NASDAQ:ALRN), a biopharmaceutical company advancing a novel pipeline of first-in-class medicines to address significant unmet medical needs in orphan pulmonary and fibrosis indications, today announced the completion of enrollment in Cohort 2 of the ongoing Phase 1b clinical trial of LTI-03 in IPF patients.
The last patient was enrolled in mid-September, with a total of 24 patients enrolled in the trial. Eligible patients are randomly assigned (3:1) to receive either inhaled LTI-03 or placebo. The primary objective of the trial is to evaluate the safety and tolerability of LTI-03 in patients with IPF after treatment for 14 consecutive days, with measurement of multiple protein biomarkers as exploratory endpoints.
"We are pleased to have completed enrollment in the high-dose cohort of our Phase 1b clinical trial and grateful to all participating patients and investigators," said Brian Windsor, Ph.D., President and Chief Executive Officer of Aileron. "Following the positive trend observed in the low-dose cohort, we are excited to assess the safety, tolerability and biomarkers of 5 mg twice daily of inhaled LTI-03 and expect to report topline data in the near term."
In May 2024, the Company announced positive data from Cohort 1 evaluating low-dose LTI-03 (2.5 mg BID). Following inhaled administration of low-dose LTI-03 in 12 patients, a positive trend was observed in seven out of eight biomarkers with evidence of reduced expression among multiple profibrotic proteins produced by basal-like cells and fibroblasts that contribute to the progression of IPF, including data from three biomarkers that was statistically significant, reinforcing the potential of LTI-03 to improve lung function and reverse the course of IPF.
About the Phase 1 Clinical Trial of LTI-03
The Phase 1b clinical trial of LTI-03 is a randomized, double-blind, placebo controlled, multi-center, dose escalation trial in patients recently diagnosed with IPF that have not received prior treatment with anti-fibrotic agents for at least two months (NCT05954988). Eligible patients are randomly assigned (3:1) to receive one of two doses of inhaled LTI-03 or placebo. The primary objective of the trial is to investigate the safety and tolerability of LTI-03 in patients with IPF after treatment for 14 consecutive days, with measurement of multiple protein biomarkers as exploratory endpoints.
