GRI Bio reports positive safety data for IPF treatment candidate

LA JOLLA, CA - GRI Bio, Inc. (NASDAQ:GRI) announced Thursday that its Phase 2a study of GRI-0621 for idiopathic pulmonary fibrosis (IPF) treatment has yielded positive 6-week interim safety results, with the Independent Data Monitoring Committee recommending continuation of the trial. The clinical-stage biotech company, with a market capitalization of $3.2 million, maintains a strong balance sheet with more cash than debt, according to InvestingPro data.

The interim analysis showed GRI-0621, a small molecule RAR-βδ dual agonist that inhibits Type 1 Invariant NKT cell activity, was safe and well-tolerated in the first 24 patients evaluated. No adverse events related to hyperlipidemia were observed, with no clinically meaningful changes in HDL, LDL, or triglyceride levels.

"We are encouraged by the consistent safety data and early anti-fibrotic trends previously reported," said Marc Hertz, CEO of GRI Bio, according to the company’s press release.

The ongoing Phase 2a study is a randomized, double-blind, multi-center trial enrolling approximately 36 IPF patients, who receive either 4.5mg of GRI-0621 or placebo once daily for 12 weeks in a 2:1 ratio. The primary endpoint is safety and tolerability after 12 weeks of treatment.

Secondary endpoints include changes in serum biomarkers, pharmacokinetics assessment, and determination of pharmacodynamic activity through inhibition of iNKT cell activation in blood and bronchoalveolar lavage fluid.

The company expects to report 6-week interim biomarker data in July 2025, with topline results anticipated in the third quarter of 2025. While the stock has faced significant pressure, falling over 90% year-to-date, analysts maintain optimistic price targets ranging from $10 to $34. InvestingPro analysis suggests the stock may be undervalued at current levels, with 11 additional ProTips available to subscribers covering crucial financial metrics and market trends.

IPF is a serious lung disease with limited treatment options. Currently, only two approved drugs are available, which the company notes come with significant side effects, limited patient compliance, and no impact on survival.
