Ongoing progress towards completion of IND-enabling studies in SLE program for GRI-0803 with IND filing expected in H1 2024

LA JOLLA, CA, Aug. 14, 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 reported its financial results for the quarter ended June 30, 2023 and provided a corporate update.

“The past quarter was marked by a number of critical advancements on both the clinical and corporate sides of our business. We are in the final stages of preparation for the launch of our Phase 2a biomarker study, which is expected this year. This study will evaluate our lead program, GRI-0621 for the treatment of IPF, an Orphan indication in need of innovative solutions. We are also finalizing our IND-enabling studies for our SLE program with the goal of filing an IND in the first half of 2024,” commented Marc Hertz, PhD, Chief Executive Officer of GRI Bio.

“On the corporate side, we closed our merger and began trading on the Nasdaq under the ticker ‘GRI,’ which we believe sets the stage for the future success of the Company. We also refreshed our corporate identity and launched a new corporate website, which is in line with our mission going forward and provides all key stakeholders a reliable source to access information and updates on the Company,” continued Dr. Hertz.

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-βɣ dual agonist that inhibits the activity of human type 1, 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.

Key Highlights:

  • Orphan indication with ~40,000 newly diagnosed cases in the United States annually2
  • Currently available treatments for IPF are limited with only two approved drugs that come with significant side-effects, limited compliance and no impact on survival3
    • Despite challenges, total 2022 sales of the two approved drugs in the United States were ~$4.3 billion combined4
  • GRI-0621 is designed to target upstream in the inflammatory cascade and to provide potential for greater efficacy
  • Established safety profile as an oral formulation
  • iNKT inhibition demonstrated fibrosis resolution in multiple animal models
  • Extensive IP protection with issued medical use patents and market LOE through 2036

Expected GRI-0621 Upcoming Milestones

  • H2 2023: Launch Phase 2a biomarker study
  • H1 2024: Report interim data from Phase 2a biomarker study
  • H2 2024: Report topline results from Phase 2a biomarker study

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.

Key Highlights:

  • Annual prevalence estimated to be ~161,000 people in the United States affected with definite SLE5
  • Current treatments for SLE are limited, consisting primarily of immunosuppressive therapies
  • GRI-0803 is designed to target upstream in the inflammatory cascade and to provide potential for greater efficacy
  • Oral administration in a spontaneous model of lupus nephritis demonstrated significant inhibition of pro-inflammatory cytokines, including IL-6 and IL-17; significant inhibition of autoantibodies; and improvement in overall and proteinuria-free survival

Expected GRI-0803 Upcoming Milestones

  • H1 2024: Complete IND-enabling studies
  • H1 2024: File IND
  • Q3 2024: Report Phase 1a SAD topline results
  • Q4 2024: Report Phase 1b MAD topline results

Summary of Financial Results for Second Quarter 2023

Net loss was $8.9 million for the six months ended June 30, 2023.

Research and development expenses were $0.9 million and $0.1 million for the three months ended June 30, 2023 and 2022, respectively. The $0.8 million increase in research and development expenses was primarily due to increases of $0.4 million in expenses related to the development program of GRI-0621, $0.2 million in consulting fees and $0.2 million in personnel expenses.

General and administrative expenses were $5.1 million and $0.1 million for the three months ended June 30, 2023 and 2022, respectively. The $5.0 million increase was primarily related to increased costs for professional fees, including legal, accounting and investment banking fees associated with the Merger, of $3.8 million, personnel expenses of $0.8 million as a result of increased headcount, and increases in consulting, administrative and insurance expenses of $0.3 million as a result of operating as a public company.

As of June 30, 2023, the Company had cash and cash equivalents of approximately $4.8 million.

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.
