- Rein Therapeutics Inc. is a clinical-stage biopharmaceutical company focused on developing first-in-class therapies for orphan pulmonary and fibrosis indications. The company’s core products include LTI-03, a novel synthetic peptide designed to treat idiopathic pulmonary fibrosis (IPF) by promoting alveolar epithelial cell survival and inhibiting profibrotic signaling; LTI-01, a proenzyme with completed Phase 1b and Phase 2a trials for loculated pleural effusions; and a pipeline of preclinical programs targeting cystic fibrosis and systemic fibrosis, including a peptide program focused on caveolin-1 protein and LTI-05, an epithelial sodium channel therapy. Rein Therapeutics primarily operates in the United States and internationally through clinical trial sites in the United Kingdom, Germany, Poland, and Australia. The company was founded in 2001 and is headquartered in Austin, Texas. Recent major developments include the lifting of the U.S. FDA's full clinical hold on Rein's Phase 2 RENEW trial of LTI-03 for IPF, enabling the company to resume enrollment across approximately 20 U.S. sites in late 2025 or early 2026, complementing about 30 global sites. Early data from the ongoing trial suggest that LTI-03 may slow fibrosis and support lung repair. The company has also secured European Medicines Agency (EMA) authorization in October 2025 to initiate its global Phase 2 trial program, including sites in Germany and Poland. Additionally, Rein entered into strategic financing agreements in mid-2025 providing potential access to up to $21 million in capital to support the advancement of its clinical programs. A collaboration with Qureight Ltd. has been announced to integrate deep-learning platforms into Rein’s Phase 2 clinical trial, reflecting a strategic use of technology to enhance trial outcomes. Rein operates within the biotechnology sector, addressing significant unmet medical needs in rare and orphan disease markets, targeting patient populations with pulmonary fibrosis, pleural effusions, and cystic fibrosis. The company evolved from Aileron Therapeutics, Inc., renaming to Rein Therapeutics Inc. in 2007. Its pipeline and clinical activities underscore a commitment to developing transformative therapies for underserved pulmonary diseases with global clinical operations and financial strategies to advance its innovative drug candidates. The company is led by CEO James Windsor and maintains its clinical development focus on orphan and rare disease indications.
