Aileron Therapeutics to Present Previously Announced Data from the Phase 1b Clinical Trial Evaluating Low-Dose LTI-03 in Idiopathic Pulmonary Fibrosis (IPF) at the 22nd International Colloquium on Lun

The first scientific presentation of previously announced data from Cohort 1 of an ongoing Phase 1b clinical trial evaluating low-dose LTI-03 (2.5 mg twice daily) in IPF, confirms positive trends in seven of the eight biomarkers evaluated, suggesting to a potential therapeutic effect

Enrollment in the second cohort evaluating high-dose LTI-03 (5 mg BID) was recently completed in mid-September; Key data expected in the near term

, /PRNewswire/ — Therapeutic Airfoils (NASDAQ:), Inc. (“Aileron”) (NASDAQ: ALRN), a biopharmaceutical company developing a new pipeline of first-in-class drugs to address significant unmet medical needs in orphan pneumonia and pulmonary fibrosis indications, today announced the filing of two briefs detailing the pre-LTI -03 – Clinical and Phase 1b (NCT05954988) leads to idiopathic pulmonary fibrosis (IPF) at 22Second abbreviation International Symposium on Lung and Airway Fibrosis (ICLAF).

The company previously Positive data announced From Cohort 1 of the current Phase 1b clinical trial evaluating low-dose LTI-03 (2.5 mg BID) in patients with IPF. Following low-dose inhalation of LTI-03 in 12 patients over 14 days, a positive trend was observed in seven out of eight biomarkers with evidence of decreased expression among multiple chaperone proteins produced by basal-like cells and fibroblasts contributing to this. to the development of IPF, including data from three biomarkers (collagen synthesis, inflammation, and fibrosis) that were statistically significant, strengthening the potential of LTI-03 to improve lung function and reverse IPF. (Poster) (Abstracts) to be presented at ICLAF will summarize previously disclosed data from Cohort 1.

Preclinical data presented at ICLAF also support the potential therapeutic efficacy of LTI-03 for IPF through precision-cut lung segments (PCLS) performed ex vivo. Preclinical studies demonstrated molecular activity in IPF PCLS explants indicative of fibrosis within five days in culture and LTI-03 broadly attenuated pro-fibrotic proteins and pathways.

Additionally, the company recently announced the completion of enrollment in the second arm of an ongoing phase 1 clinical trial evaluating high doses of LTI-03 (5 mg BID) in 12 patients with IPF. In the trial, eligible patients (n = 24) were randomly assigned (3:1) to receive either LTI-03 inhalation 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 multiple protein biomarkers measured as exploratory endpoints. The company expects to report key data for this group in the near term.

About the phase 1 clinical trial of LTI-03

The phase 1 clinical trial of LTI-03 is a randomized, double-blind, placebo-controlled, multicenter, dose-escalation trial in patients newly diagnosed with IPF who have not received prior treatment with antifibrotic agents for at least 2 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 multiple protein biomarkers measured as exploratory endpoints.

About IPF

IPF is a chronic lung disease characterized by progressive tissue scarring that prevents proper lung function. It is a progressive, fatal, age-related lung disease that affects approximately 100,000 people worldwide. 1. IPF usually occurs in adults age 65 or older and is usually fatal within two to five years after diagnosis2.

About LTI-03 and Caveolin-1 (Cav1)

LTI-03 is a seven-amino acid peptide, whose sequence is derived from the caveolin scaffolding domain (CSD), an important binding region of the Cav1 protein. Cav1 normally performs a critical function in the prevention of fibrosis by maintaining a balance between the pathways that initiate and stop lung repair and cell motility. Through the CSD, caveolin interacts with a large number of signaling molecules, all of which possess a caveolin-binding region. Cav1 expression is decreased in IPF lung tissue and has been shown to be reduced during the fibrotic phase of bleomycin lung injury in mice. Restoring the balance of important biological signals in the lung may not only slow the decline of lung function, but may also restore healthy lung function by protecting healthy epithelial cells.

on Aileron treatments

Aileron Therapeutics is a biopharmaceutical company developing a novel pipeline of first-in-class drugs to address important unmet medical needs in pulmonary fibrosis and pulmonary fibrosis indications. Aileron’s lead product candidate, LTI-03, is a novel synthetic peptide with a dual mechanism that targets alveolar epithelial cell survival as well as inhibiting fibrotic signaling. Currently, LTI-03 is being evaluated in a phase I clinical trial for the treatment of idiopathic pulmonary fibrosis. Aileron’s second product candidate, LTI-01, is a prototypic enzyme that has completed Phase 1b and Phase 2a clinical trials for the treatment of topical pleural eczema. LTI-01 has received Orphan Drug Designation in the US and EU and Fast Track Designation in the US.
