This is a randomized, multicenter, open-label, phase 3 study evaluating the efficacy, safety, and tolerability of IBI354 combined with or without pertuzumab vs. THP as first-line treatment for HER2-positive unresectable, locally advanced or metastatic breast cancer.

This is a multicenter, randomized, double-blind, placebo-controlled Phase II/III clinical trial evaluating the efficacy and safety of picankibart (IBI112) in patients with active psoriatic arthritis (PsA). The study consists of two stages: Phase II dose-finding (n=90) and Phase III confirmatory (n=132). Participants will receive subcutaneous (SC) injections of either picankibart (200mg) or placebo with different dosing schedules, with placebo crossover to active treatment at Week 26. The Phase II portion will identify optimal dosing for Phase III, which will confirm efficacy. The study will evaluate improvements in joint symptoms, physical function, quality of life, and skin manifestations. Primary endpoint is percentage of participants who achieved an American College of Rheumatology (ACR) 20 Response at Week 24.

The purpose of this study is to evaluate the efficacy and safety of IBI112 in the treatment of adolescent participants with moderate to severe plaque-type psoriasis.
