Interim data readout of Phase 2a biomarker study evaluating lead program GRI-0621 for the treatment of Idiopathic Pulmonary Fibrosis (IPF) expected Q3 2024 and topline data on track for Q4 2024

Ongoing progress of Investigational New Drug (IND) enabling studies in systemic lupus erythematosus (SLE) program for GRI-0803 with IND filing expected in H2 2024

LA JOLLA, CA, May 13, 2024 (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 reported its financial results for the first quarter ended March 31, 2024 and provided a corporate update.

“We continue to execute on both the clinical and corporate fronts. Our team is working diligently to drive our Phase 2a biomarker study in IPF toward interim data readout which we believe will provide valuable insight for our development program moving forward,” commented Marc Hertz, PhD, Chief Executive Officer of GRI Bio. “On the corporate side, we continue to bolster our patent estate as well as actively engage with and present at scientific meetings which we believe underscore the potential of GRI-0621. We are committed to building a growing body of data and believe we are positioned to unlock significant value in 2024.”

Recent Highlights

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 survival1.

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 and has launched a Phase 2a biomarker study evaluating GRI-0621 for the treatment of IPF. For more information about the Phase 2a study, please visit clinicaltrials.gov and reference identifier NCT06331624.

Expected GRI-0621 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 SLE.

SLE is an autoimmune disease in which the immune system attacks its own tissue and organs. SLE is the most common form of lupus. Current treatments are limited, consisting primarily of immunosuppressive therapies.

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.

Summary of Financial Results for First Quarter 2024

Net loss was $1.9 million for the three months ended March 31, 2024.

Research and development expenses were $0.9 million and $0.1 million for the three months ended March 31, 2024 and 2023, respectively.

General and administrative expenses were $1.0 million and $0.9 million for the three months ended March 31, 2024 and 2023, respectively.

As of March 31, 2024, the Company had cash and cash equivalents of approximately $4.1 million. In February 2024, the Company closed a public offering with participation from healthcare focused institutional investors for aggregate gross proceeds of $5.5 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 third quarter of 2024.

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 IPF, a serious disease with significant unmet need. The Company is also developing a pipeline of novel type 2 NKT agonists for the treatment of SLE. Additionally, with a library of over 500 proprietary compounds, GRI Bio has the ability to fuel a growing pipeline.
