GRI Bio (NASDAQ: GRI) Bolsters Patent Portfolio

U.S. patent issuance for lead program, GRI-0621, in development for the treatment of idiopathic pulmonary fibrosis (IPF)

Company building a robust global patent estate

LA JOLLA, CA, June 27, 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 an update to the progress of its patent portfolio development.

Most recently, the Company received notice that the United States Patent and Trademark Office (USPTO) has issued U.S. Patent No. 11,660,309 entitled, “Prevention and treatment of inflammatory conditions, covering methods for the prevention and treatment of inflammatory conditions. More specifically, the patent covers the prevention and treatment of inflammatory and fibrotic conditions through the administration of a Retinoic Acid Receptor (RAR) agonist that inhibits type 1 invariant NKT (iNKT) cells, and at its broadest covers the administration of an RAR agonist that inhibits the activity of iNKT cells in a subject.

GRI-0621 is the Company’s small molecule RAR-βɣ dual agonist candidate that inhibits the activity of human iNKT cells. In clinical trials/pre-clinical studies with GRI-0621, reduced aminotransferases and other LFTs in patients and improved fibrosis in multiple disease models were observed. GRI is 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 launch a Phase 2a biomarker study evaluating GRI-0621 for the treatment of IPF in the second half of 2023.

“Establishing a strong global patent estate for our innovative pipeline continues to be an area of focus for the Company as we continue to advance development. We are pleased to have been issued this latest U.S. patent for GRI-0621 which extends our patent coverage to 2032 and which we believe provides further validation of our differentiated approach. Over the course of the past year, we have significantly added to our patent estate, underscoring our commitment to advance much needed treatment options for inflammatory, fibrotic and autoimmune diseases,” commented Marc Hertz, Ph.D., Chief Executive Officer of GRI Bio.

Additionally, over the course of the past year, the Company has bolstered its IP protection with the issuance of several U.S. and ex-U.S. patents for the GRI-0621, GRI-0803, GRI-0124, and GRI-0729 development programs:


  • Russian Patent No. RU2789326
  • Brazilian Patent No. BR112013033309B1


  • U.S. Patent No. 11,453,642


  • China Patent No. CN107206086B
  • Hong Kong Patent No. HK1243961


  • U.S. Patent No. 11,564,895

The Company remains committed to bolstering its IP protection across its innovative pipeline of NKT cell modulators.

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.
