Shenzhen Chipscreen Biosciences (688321.SH): CS32582 capsules have been granted approval for Phase I clinical trials for the treatment of psoriasis.

Shenzhen Chipscreen Biosciences (688321.SH) announced that its wholly-owned subsidiary, Chengdu Microcore Pharmaceuticals Co., Ltd., recently received the Drug Clinical Trial Approval Notice for domestic drug production and registration issued by the National Medical Products Administration. The application for Phase I clinical trial of CS32582 capsules for the treatment of psoriasis has been approved. CS32582 is a selective small molecule allosteric inhibitor of TYK2 developed by the company. It achieves selective inhibition of TYK2's specific biological functions by specifically binding to the regulatory pseudokinase JH2 domain of TYK2, locking it in an inactive conformation, while not significantly affecting the activity mediated by other members of the JAK family. CS32582 has demonstrated clear efficacy and good safety in preclinical studies, and has high oral bioavailability in animal models.
