GRI Bio (NASDAQ: GRI) presented positive preclinical data for its lead program GRI-0621 at the 22nd International Colloquium on Lung and Airway Fibrosis. The data demonstrated GRI-0621's ability to inhibit invariant Natural Killer T (iNKT) cell activity and reduce inflammatory and fibrotic drivers in Idiopathic Pulmonary Fibrosis (IPF).
Key findings include:
Increased expression of pro-fibrotic factors in IPF patients
Increased IFN-γ producing NKT cells in IPF patients
GRI-0621 treatment improved inflammatory, fibrotic, and pathological features in a bleomycin model of pulmonary fibrosis
GRI Bio is currently conducting a Phase 2a biomarker study of GRI-0621 in IPF patients, with interim data expected in Q4 2024 and topline results in Q1 2025.
