Equillium Announces Poster Presentations at IMMUNOLOGY2026™, the Annual Meeting of the American Association of Immunologists
LA JOLLA, Calif., April 08, 2026 (GLOBE NEWSWIRE) -- Equillium, Inc. (Nasdaq: EQ), a biotechnology innovator developing novel therapies to treat severe autoimmune and inflammatory disorders, today announced that new EQ504 preclinical data have been accepted for poster presentations at , the annual meeting of the American Association of Immunologists taking place in Boston, Massachusetts, April 15-19, 2026.
“We are excited to share these preclinical findings that support the differentiated profile of EQ504 as a potent AhR modulator, with the potential to influence both immune cell responses and barrier restoration,” said Dr. Stephen Connelly, Chief Scientific Officer of Equillium. “Together, these attributes are particularly important in diseases such as ulcerative colitis, where both reducing inflammation and improving mucosal healing are critical to achieving meaningful outcomes for patients.”

About EQ504
EQ504 is an investigational potent and selective aryl hydrocarbon receptor (AhR) modulator with a multi-modal, non-immunosuppressive mechanism of action designed to be complementary to other inflammation and immunology agents. AhR is critical to barrier organ tissue physiology and immunology, maintaining barrier function and promoting tissue repair and regeneration, while regulating resident immune cells with anti-inflammatory responses. EQ504’s preclinical properties provide the potential for targeted, local delivery via enteric coating for the treatment of ulcerative colitis and other gastrointestinal diseases or inhaled formulations for the treatment of inflammatory lung diseases.
