Interim data and topline data readouts from Phase 2a biomarker study expected in Q2 2025 and Q3 2025, respectively Cash runway expected to fund operations into Q2 2025, including interim data readout from GRI-0621 LA JOLLA, CA, March 17, 2025 (GLOBE NEWSWIRE) -- GRI Bio, Inc. (NASDAQ: GRI) (“GRI Bio” or the “Company”), a biotechnology company advancing an innovative pipeline of Natural Killer T (“NKT”) cell modulators for the treatment of inflammatory, fibrotic and autoimmune diseases, has reported its financial results for the fiscal year ended December 31, 2024 and today provided a corporate update. “Over the last year, we made significant progress on the development of our lead program GRI-0621 for the treatment of IPF. We continue to make strides towards our anticipated interim data readout and topline data readout which remain on track for the second and third quarter of 2025, respectively. We remain confident that the data observed to date, and the additional data readouts anticipated this year, will position us to build momentum and drive value for shareholders in the near and long term,” commented Marc Hertz, PhD, Chief Executive Officer of GRI Bio. Recent Highlights Presented positive preclinical data demonstrating its lead program GRI-0621 reduces important inflammatory and fibrotic drivers in IPF at the 8th Annual Antifibrotic Drug Development Summit; andGranted European patent covering GRI-0803 and the Company’s library of 500+ proprietary compounds. GRI-0621: Type 1 Invariant NKT (“iNKT”) Antagonist in Development for the Treatment of IPF. IPF is a rare chronic progressive pulmonary disease with abnormal scarring of the lung blocking the movement of oxygen into the bloodstream. Currently available treatments for IPF are limited with only two approved drugs that come with significant side-effects, limited compliance and no impact on overall survival1, leaving significant opportunity to augment IPF treatment with a new therapeutic. GRI Bio’s lead program, GRI-0621, is a small molecule RAR-βɣ dual agonist that inhibits the activity of human iNKT cells. In preliminary trials to date and previous trials with the oral formulation, GRI-0621 has been shown to improve fibrosis in multiple disease models and improve liver function tests and other markers of inflammation and injury in patients. The Company plans to leverage the 505(b)(2) regulatory pathway for this candidate. For more information about the Phase 2a study, please visit clinicaltrials.gov and reference identifier NCT06331624. Expected GRI-0621 Upcoming Milestones Q2 2025: Report interim data from Phase 2a biomarker studyQ3 2025: Report topline results from Phase 2a biomarker study Summary of Financial Results for Full Year 2024 Net loss was $8.2 million for the year ended December 31, 2024. Research and development expenses were $3.8 million and $3.2 million for the years ended December 31, 2024 and 2023, respectively. The $0.6 million increase in research and development expenses was primarily due to increased expenses related to the registrational development program of GRI-0621. General and administrative expenses were $4.5 million and $8.2 million for the years ended December 31, 2024 and 2023, respectively. The $3.7 million decrease was primarily due to a decrease of $3.4 million in accounting, legal, investment banking and other fees related to the merger with Vallon Pharmaceuticals, Inc. in April 2023. As of December 31, 2024, the Company had cash and cash equivalents of approximately $5.0 million. Based on the Company’s current operating plan, the Company believes that its existing cash and cash equivalents will be sufficient to fund its operating expenses and capital expenditure requirements into the second quarter of 2025. About GRI Bio, Inc. GRI Bio is a clinical-stage biopharmaceutical company focused on fundamentally changing the way inflammatory, fibrotic and autoimmune diseases are treated. GRI Bio’s therapies are designed to target the activity of NKT cells, which are key regulators earlier in the inflammatory cascade, to interrupt disease progression and restore the immune system to homeostasis. NKT cells are innate-like T cells that share properties of both NK and T cells and are a functional link between the innate and adaptive immune responses. iNKT cells play a critical role in propagating the injury, inflammatory response, and fibrosis observed in inflammatory and fibrotic indications. GRI Bio’s lead program, GRI-0621, is an inhibitor of iNKT cell activity and is being developed as a novel oral therapeutic for the treatment of idiopathic pulmonary fibrosis, a serious disease with significant unmet need. The Company is also developing a pipeline of novel type 2 diverse NKT agonists for the treatment of systemic lupus erythematosus. Additionally, with a library of over 500 proprietary compounds, GRI Bio has the ability to fuel a growing pipeline.

– Company committed to building a robust global patent estate across its innovative pipeline of NKT cell modulators Dec. 23, 2024 -- GRI Bio, Inc. (NASDAQ: GRI) (“GRI Bio” or the “Company”), a biotechnology company advancing an innovative pipeline of Natural Killer T (“NKT”) cell modulators for the treatment of inflammatory, fibrotic and autoimmune diseases, today announced that European Patent Office (EPO) has issued a decision to grant notice for patent application number 19,166,502 titled, “Oxygenated Amino- or Ammonium-Containing Sulfonic Acid, Phosphonic Acid and Carboxylic Acid Derivatives and Their Medical Use.” Based on the intention to grant notice, the Company expects the EPO to issue a patent January 16, 2025. “We have continued to make encouraging progress in our initiative to bolster our global patent estate covering our innovative pipeline of NKT cell modulators and library of over 500 proprietary compounds. We are pleased to add this anticipated European patent to our intellectual property portfolio. We continue to believe in our highly differentiated approach to the prevention and treatment of inflammatory, fibrotic and autoimmune diseases and look forward to further advancing their development to ultimately address areas of significant unmet medical need,” Marc Hertz, PhD, Chief Executive Officer of GRI Bio. The patent claims include coverage of GRI-0803, the Company’s novel activator of human type 2 NKT cells in development for the treatment of autoimmune disorders, with an initial focus on systemic lupus erythematosus (SLE). Activation of type 2 NKT leads to a dendritic cell-mediated inhibition of iNKT cells. In the Company’s preclinical studies, type 2 NKT activating molecules, GRI-0803 and GRI-0124, were observed to inhibit both murine and human iNKT cells. Oral administration of these type 2 NKT activating molecules was observed to inhibit lupus nephritis and to significantly improve overall survival. The Company is currently focusing its available resources on GRI-0621, but, pending additional funding, the GRI-0803 IND-enabling and Phase1 program will continue in 2025. The Company is currently advancing the development of its lead program, GRI-0621, in a Phase 2a, randomized, double-blind, multi-center, placebo-controlled, parallel-design, 2-arm study for the treatment of IPF. Interim data from the Phase 2a biomarker study is expected in the first quarter of 2025 and topline results are expected in the second quarter of 2025.
