Aileron Therapeutics and Pulmonary Care Experts To Discuss the Potential Implications of LTI-03 for Idiopathic Pulmonary Fibrosis in Virtual Key Opinion Leader Event

WALTHAM, Mass., Feb. 15, 2024 (GLOBE NEWSWIRE) -- 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, will host a virtual key opinion leader event today from 4:30 to 5:30 p.m. ET titled “Clinical Perspectives on Treating Idiopathic Pulmonary Fibrosis” featuring pulmonary care experts Fernando J. Martinez, M.D., M.S. from Weill Cornell Medicine; Tejaswini Kulkarni, M.D., M.P.H. from University of Alabama at Birmingham Medicine; and Andreas Günther, M.D. from Agaplesion Evang. Central Hesse Hospital and Justus Liebig University.

The event will include presentations by Aileron management followed by a panel discussion with the key opinion leaders on the treatment landscape for idiopathic pulmonary fibrosis (IPF), including the current challenges and significant unmet needs that remain for patients with the disease and the Company’s lead product candidate, LTI-03. A live question-and-answer session will follow.

“As practicing clinicians and experts in pulmonary care medicine, these key opinion leaders bring valuable experience to the discussion of LTI-03 as a potential treatment option for patients with IPF,” said Cory Hogaboam, Ph.D., Chief Scientist of Aileron. “While Aileron expects to announce topline data from our Phase 1b study of LTI-03 in the second quarter of this year, we are encouraged by the support of these experts for the work we are doing to address the significant unmet need in this patient population.”

IPF is a chronic lung disease characterized by progressive tissue scarring that prevents proper lung function. It is a progressive, fatal, age-associated lung disease affecting approximately 100,000 people in the United States¹. IPF typically presents in adults 65 or older and is usually fatal within two to five years after diagnosis².

Aileron’s lead product candidate, LTI-03, is a novel Caveolin-1-related (Cav1) peptide with a dual mechanism targeting both alveolar epithelial cell survival as well as inhibition of profibrotic signaling, whereas approved drugs for the treatment of IPF, such as nintedanib and pirfenidone, have only demonstrated a reduction of profibrotic signaling. Studies conducted by Aileron and third parties have demonstrated that Cav1 is a key protein in the regulation of lung fibrosis that has a decreased expression in IPF patients. LTI-03 completed a Phase 1a clinical trial in healthy volunteers and is currently in a randomized, double-blind, placebo-controlled Phase 1b clinical trial in IPF patients. Aileron expects to announce topline results from this study in the second quarter of 2024.

About LTI-03 and Caveolin-1 (Cav1)

LTI-03 is a seven amino acid peptide, the sequence of which is derived from the caveolin scaffolding domain (CSD), an important binding region of the Cav1 protein. Cav1 normally serves a critical function in the prevention of fibrosis by maintaining a balance between pathways that both initiate and arrest lung repair and cell movement. Through the CSD, caveolin interacts with a large number of signaling molecules, all of which possess a caveolin binding sequence region. Cav1 expression is decreased in IPF lung tissues and has been demonstrated to decrease during the fibrotic phase of bleomycin, or BLM, lung injury in mice. Restoring the balance of important biological signals in the lung may not only slow lung function decline but could also restore healthy lung function through the protection of healthy epithelial cells.

About Aileron Therapeutics

Aileron Therapeutics is a biopharmaceutical company advancing a novel pipeline of first-in-class medicines to address significant unmet medical needs in orphan pulmonary and fibrosis indications. Aileron’s lead product candidate, LTI-03, is a novel, synthetic peptide with a dual mechanism targeting alveolar epithelial cell survival as well as inhibition of profibrotic signaling. Currently, LTI-03 is being evaluated in a Phase 1b clinical trial for the treatment of idiopathic pulmonary fibrosis, with topline results expected to be reported by the end of 2Q24. Aileron’s second product candidate, LTI-01, is a proenzyme that has completed Phase 1b and Phase 2a clinical trials for the treatment of loculated pleural effusions. LTI-01 has received Orphan Drug Designation in the US and EU and Fast Track Designation in the US.
