Inventisbio Co.,Ltd. (688382.SH) announced that patient enrollment has been completed for the registrational Phase III clinical trial of its self-developed TYK2 inhibitor D-2570, intended for the treatment of moderate-to-severe plaque psoriasis. The company-developed D-2570 is a novel oral selective inhibitor targeting tyrosine kinase 2 (TYK2) and is designed to treat autoimmune diseases such as psoriasis. D-2570 works by selectively binding to the JH2 domain of the TYK2 pseudokinase, inhibiting TYK2 kinase activity, thereby blocking TYK2-dependent cytokine signaling-mediated phosphorylation of STAT proteins. This mechanism reduces the release of inflammatory factors and contributes to immune regulation.
