InnoCare Announces First Healthy Volunteer Dosed in Clinical Trial of Novel VAV1 Degrader ICP-538 in China

BEIJING, March 15, 2026 (GLOBE NEWSWIRE) -- InnoCare Pharma (HKEX: 09969; SSE: 688428), a leading biopharmaceutical company focusing on the treatment of cancer and autoimmune diseases, announced today that the first healthy volunteer has been dosed in a clinical trial of ICP-538, a VAV1-directed molecular glue degrader (MGD), in China. This is the first VAV1 degrader approved to enter clinical trials in China and the second globally.

ICP-538 is a novel, potent, highly selective, orally administered molecular glue degrader targeting VAV1, a key protein downstream of T-cell and B-cell receptors. ICP-538 induces rapid and efficient degradation of VAV1 protein in a dose-dependent manner by selectively mediating the formation of a ternary complex between the CRBN E3 ubiquitin ligase and the VAV1 protein. ICP-538 will be developed for the treatment of autoimmune diseases, such as inflammatory bowel disease, systemic lupus erythematosus, and multiple sclerosis. Currently, there are no approved VAV1-targeted therapies globally.

Degradation of VAV1 can effectively inhibit T-cell proliferation, differentiation, activation, and cytokine release, as well as B-cell activation and cytokine release, thereby exerting anti-inflammatory and immunomodulatory effects and alleviating autoimmune and inflammatory pathological processes. Preclinical studies have shown that ICP-538 induces deep degradation of VAV1, leading to a significant reduction in cytokines associated with immune-mediated diseases, with no detectable effects on other proteins.

Dr. Jasmine Cui, the Co-founder, Chairwoman, and CEO of InnoCare, said, “We are committed to developing innovative drugs in the field of autoimmune diseases. As a novel therapy, the VAV1 molecular glue degrader offers three major advantages: high target selectivity, mediation of multiple mechanisms of action, and high efficacy. We are pleased to see that we have rapidly advanced clinical development, and we believe that ICP-538 will become a better treatment option for patients with autoimmune diseases.”
