GRI Bio (NASDAQ: GRI) Provides Business Outlook and Highlights Upcoming Milestones for Innovative Pipeline of NKT Cell Modulators
Rapidly advancing clinical pipeline in potential high-value inflammatory, fibrotic and autoimmune diseases
Leading NKT regulation technology targeting earlier in the inflammatory cascade to modulate disease progression
LA JOLLA, CA, May 22, 2023 (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, today provided a business outlook and highlighted upcoming milestones for its innovative pipeline of NKT cell modulators in development.
“We believe our leading NKT platform technology represents a compelling opportunity with the potential for significant value creation. Based on the data demonstrated to date, we have confidence in our ability to modulate inflammatory diseases earlier in the cascade to interrupt disease progression and provide benefit to patients. We continue to make solid progress in the advancement of our lead programs, GRI-0621 and GRI-0803, and are poised to reach a number of value-driving milestones in the near term,” commented Marc Hertz, PhD, Chief Executive Officer of GRI Bio. “On the corporate front, we believe we have investment proceeds and access to additional investment to fund planned operations through 2024 and have bolstered the expertise of our team and Board of Directors. We are well prepared to rapidly propel the Company forward and are committed to providing much needed treatment options for inflammatory, fibrotic and autoimmune diseases.”
GRI-0621: Type 1 invariant NKT (“iNKT”) antagonist in development for the treatment of idiopathic pulmonary fibrosis (IPF).
IPF is a rare chronic progressive pulmonary disease with abnormal scarring of the lung blocking the movement of oxygen into the bloodstream. GRI Bio’s lead program, GRI-0621 is a small molecule RAR-ß? dual agonist that inhibits the activity of human Type I, iNKT cells. In preliminary trials to date1 and previous trials with the oral formulation, GRI-0621 has been shown to improve fibrosis in multiple disease models and improve LFTs and other markers of inflammation and injury in patients.
GRI is developing and repurposing GRI-0621 as a once-daily oral capsule for the treatment of IPF with the potential to expand into additional fibrotic indications. The Company plans to leverage the 505(b)(2) regulatory pathway and to launch a Phase 2a biomarker study evaluating GRI-0621 for the treatment of IPF. The 2:1 randomized Phase 2a study is expected to enroll approximately 36 patients on background IPF therapy. At present, the planned primary endpoint for the study is safety and tolerability of oral GRI-0621 as assessed by clinical labs and adverse events (AEs) after 12 weeks of treatment. Planned secondary endpoints are change from baseline in serum biomarkers collected at Week 6 and Week 12; assessment of the pharmacokinetics (PK) of GRI-0621 at the Week 12 visit of treatment (steady state); and determining the pharmacodynamic (PD) activity of oral GRI-0621 as measured by inhibition of NKT1 cell activation in blood after 6 weeks and 12 weeks, and from bronchoalveolar lavage (BAL) fluid after 12 weeks of treatment in a Sub-Study. An additional exploratory endpoint for the study is to assess the effect of GRI-0621 on pulmonary function at baseline and after 6 weeks and 12 weeks of treatment. The Company wil conduct an interim analysis when 8 of the 12 placebo-treated patients have completed 6 weeks of treatment.
Expected Upcoming Milestones
GRI-0803: 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).
SLE, the most common form of lupus, is an autoimmune disease in which the immune system attacks its own tissue and organs. GRI Bio’s second asset in development, GRI-0803, is a novel activator of human Type 2 NKT cells. 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.
Expected Upcoming Milestones
Pipeline Expansion Opportunities
Additionally, with a library of over 500 proprietary compounds, GRI has the potential to fuel a growing pipeline. The Company has ongoing evaluations for pipeline expansion opportunities targeting potential indications in multiple sclerosis, rheumatoid arthritis, inflammatory bowel disease, insulin dependent diabetes mellitus and amyotrophic lateral sclerosis.
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. Type I invariant NKT (“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 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.
