Sino Biopharm’s Oral Psoriasis Drug TQH3906 Delivers Biologic-Like Efficacy in Phase II Trial

Sino Biopharmaceutical ( (HK:1177) ) has provided an update.

Sino Biopharmaceutical has reported positive Phase II clinical trial results for TQH3906, a Category 1 innovative oral TYK2/JAK1 JH2 allosteric inhibitor developed in-house for the treatment of moderate-to-severe plaque psoriasis. The randomized, double-blind, placebo-controlled multicenter study in 209 patients showed that at the recommended Phase II dose, TQH3906 delivered PASI 75 response rates above 90% and PASI 90 rates above 70% at 12 weeks, far exceeding placebo and demonstrating efficacy comparable to IL-17/IL-23 biologics and superior to currently marketed oral psoriasis drugs in China. Safety outcomes were favorable, with adverse events largely mild and comparable to placebo, and no new safety signals identified, underscoring the potential of TQH3906 to address a clear unmet need for highly effective, convenient oral therapies that can narrow the efficacy gap between small molecules and biologics. By targeting the pseudo-kinase domain to enhance selectivity versus traditional JAK inhibitors, the candidate could strengthen Sino Biopharmaceutical’s competitive position in immunology and dermatology, with the company planning to expand development into additional autoimmune and skin-related indications such as inflammatory bowel disease and psoriatic arthritis.
