GRI Bio Reports Breakthrough Findings on GRI-0621
Data indicates that invariant natural killer T (iNKT) cells are notably activated in the airways of patients suffering from Idiopathic Pulmonary Fibrosis (IPF). The inhibition of iNKT cell activity holds potential as a therapeutic strategy for addressing bleomycin-induced pulmonary fibrosis.
Currently, GRI Bio is progressing its Phase 2a biomarker study involving GRI-0621 in IPF patients. Interim results are anticipated in the near future, aiming for release in late 2024, with comprehensive topline data expected shortly thereafter.
Insights Presented at Leading Forum
Noteworthy findings were shared during the 22nd International Colloquium on Lung and Airway Fibrosis, highlighting the company’s commitment to advancing treatment options for IPF. Dr. Vipin Kumar Chaturvedi, the Chief Scientific Officer at GRI Bio, presented the poster titled "Involvement of Type 1 Invariant Natural Killer T Cells in Driving Lung Fibrosis." This work involved rigorous analysis of bronchoalveolar lavage (BAL) fluid from IPF patients.
Key Scientific Findings
During the research, there was a notable increase in the expression of pro-fibrotic factors such as Collagen 1-?1, osteopontin, and TGF-? within the BAL pellets from IPF patients. This was assessed using quantitative Polymerase Chain Reaction (qPCR) techniques. Furthermore, an uptick in interferon-gamma (IFN-?) producing NKT cells was identified in IPF subjects compared to control groups.
Significantly, GRI-0621 was administered during the fibrotic phases of a bleomycin-induced pulmonary fibrosis model. The treatment resulted in marked improvements across several inflammatory and fibrotic markers. These included reductions in lung injury, myofibroblast activity, collagen deposition, and overall fibrosis.
The Challenge of Idiopathic Pulmonary Fibrosis
Idiopathic Pulmonary Fibrosis (IPF) is characterized by persistent lung scarring without a known cause, severely impeding oxygen transfer into the bloodstream. The condition leads to debilitating breathlessness and dramatically lowers patients' quality of life. Untreated, the disease has a grim average survival rate of 3.5 years from diagnosis. Therapeutic options are limited, with only a couple of approved treatments that often have adverse effects and low patient adherence rates.
GRI Bio's Commitment to Innovation
GRI Bio is dedicated to revolutionizing treatment methodologies for inflammatory, fibrotic, and autoimmune pathologies. Their leading candidate, GRI-0621, functions as a small molecule RAR-?? dual agonist. It is specially formulated to inhibit human iNKT cell activity and is currently being rigorously studied in a comprehensive Phase 2a clinical trial.
As the biopharmaceutical landscape continues to evolve, GRI Bio remains optimistic regarding the potential of GRI-0621 to significantly enhance the lives of IPF patients. The upcoming interim data from the ongoing study in late 2024, followed by topline findings in early 2025, will be critical in determining the next steps for this promising therapy.

GRI Bio is also actively exploring novel type 2 NKT agonists tailored to address systemic lupus erythematosus.
Frequently Asked Questions
What is GRI-0621?
GRI-0621 is a small molecule candidate developed by GRI Bio, designed to inhibit the activity of iNKT cells in treating Idiopathic Pulmonary Fibrosis.
What are the main findings presented by GRI Bio?
Recent studies indicate that GRI-0621 significantly reduces inflammatory and fibrotic markers in IPF, demonstrating its therapeutic potential.
When can we expect interim data from the clinical study?
Interim data from the Phase 2a biomarker study of GRI-0621 is expected in late 2024.
Why is IPF considered a serious condition?
IPF leads to severe lung scarring that impedes oxygen transfer, causing breathlessness and significantly decreased quality of life, with poor survival rates when untreated.
How does GRI Bio aim to change the treatment landscape for IPF?
GRI Bio focuses on innovating therapies that target NKT cell activity, potentially offering more effective and safer options for patients with IPF compared to existing treatments.
