Gri Bio Inc. has announced topline results from its Phase 2a clinical trial evaluating GRI-0621 for the treatment of Idiopathic Pulmonary Fibrosis (IPF). The study met its primary endpoint, demonstrating that GRI-0621 was well tolerated over a 12-week treatment period. Secondary endpoints showed improvements in serum biomarkers of collagen turnover, suggesting potential fibrosis resolution and alveolar basement membrane repair. No significant safety or tolerability concerns were observed. The trial enrolled 35 subjects, with 80% receiving background standard of care treatments. Placebo-adjusted changes in Forced Vital Capacity $(FVC)$ were observed, with a higher proportion of GRI-0621-treated subjects experiencing FVC increases compared to placebo. Additional analyses of secondary and exploratory endpoints are ongoing. Results have already been presented in the company's announcement.
