InnoCare Announces First Patient Dosed in the Phase II/IIII Clinical Trial of TYK2 Inhibitor Soficitinib for Treatment of Vitiligo in China

InnoCare Pharma (HKEX: 09969; SSE: 688428), a leading biopharmaceutical company focusing on the treatment of cancer and autoimmune diseases, announced today that the first patient has been dosed in the Phase II/III clinical trial of its novel TYK2 inhibitor, Soficitinib (ICP-332), for the treatment patients with non-segmental vitiligo in China.

Soficitinib is a potent and selective TYK2 inhibitor that is being developed for the treatment of various T-cell related autoimmune disorders, including vitiligo, atopic dermatitis (AD), prurigo nodularis, etc., with broad market potential. TYK2 is a non-receptor tyrosine kinase and a member of the JAK kinase family. It plays a key role in the JAK-STAT signaling pathway and is critically involved in the pathogenesis of inflammatory diseases. 

Vitiligo happens when skin melanocytes are destroyed, leading to loss of pigment, and leaving white patches on the skin. Vitiligo affects approximately 0.5%–2% of the global population. It is a chronic condition that requires long-term treatment. The goals of therapy include disease stabilization, repigmentation, and maintenance treatment to prevent recurrence of depigmentation.

Dr. Jasmine Cui, Co-founder, Chairwoman, and CEO of InnoCare, said, “Vitiligo imposes significant psychological and social burdens on patients. Many patients experience decreased self-confidence, social barriers, and other challenges. There remains a lack of effective treatments, highlighting substantial unmet medical needs. We will accelerate the clinical development of soficitinib and look forward to bringing benefits to patients with vitiligo and other autoimmune diseases as early as possible.”

In addition to vitiligo, the clinical development of soficitinib for other autoimmune diseases is also progressing, including the Phase III registrational trial for atopic dermatitis.
