AUSTIN, Texas, June 11, 2026 (GLOBE NEWSWIRE) -- Rein Therapeutics, Inc. ("Rein" or the "Company") (NASDAQ: RNTX), a clinical-stage biopharmaceutical company advancing a novel pipeline of first-in-class medicines for orphan pulmonary and fibrosis indications, today provided an update on its ongoing Phase 2 RENEW clinical trial evaluating LTI-03 in patients with idiopathic pulmonary fibrosis (IPF).
The Company announced that the first patient has been randomized in the United Kingdom, marking another milestone in the ongoing expansion of the Phase 2 RENEW clinical trial. Rein has now enrolled 16 patients in the trial to date.
Clinical trial sites are currently enrolling patients in the United States, Australia, and the United Kingdom. Additional sites in two more countries are expected to begin enrollment in the coming months as the Company continues to expand its global clinical trial footprint.
Brian Windsor, Ph.D., Chief Executive Officer of Rein Therapeutics, commented, “We are pleased to see continued enrollment momentum in our trial and the activation of additional international sites. The enrollment of our first participant in the U.K. represents another important step in the expansion of the study. We remain focused on executing the trial efficiently and generating high-quality clinical data as we advance LTI-03 through development."
About the RENEW Phase 2 Trial
Rein’s RENEW trial is a randomized, placebo-controlled Phase 2 clinical study designed to evaluate the safety, tolerability, and efficacy of LTI-03 in patients with idiopathic pulmonary fibrosis.
The study is expected to enroll approximately 120 patients, who will be randomized to receive one of two dose levels of LTI-03 or placebo. The major efficacy endpoint is the change from baseline in forced vital capacity (FVC), a key measure of lung function.
About LTI-03
LTI-03 is a first-in-class, inhaled peptide therapy derived from Caveolin-1 biology, a key regulator of fibrotic signaling. The drug is designed to inhibit lung scarring while preserving alveolar progenitor cells that are critical for tissue repair and regeneration.
Early data suggests that LTI-03 may represent a dual-acting approach: slowing fibrosis and promoting lung healing.
