Innovent Biologics, Inc. (HKG: 1801) announced first patient dosing in the pivotal Phase 3 HeriCare-Breast01 study (NCT07377643) evaluating IBI354, its HER2-targeting antibody-drug conjugate (ADC), as first-line treatment for unresectable locally advanced or metastatic HER2-positive breast cancer. The multicenter, randomized, open-label trial positions IBI354—with its high drug-to-antibody ratio (DAR 8) and “high potency, low toxicity” profile—to challenge the current standard-of-care THP regimen (paclitaxel + trastuzumab + pertuzumab).

Forward‑Looking Statements This brief contains forward‑looking statements regarding IBI354 clinical development in HER2+ breast cancer, HeriCare study outcomes, and Innovent Biologics’ ADC commercialization strategy. Actual results may differ due to Phase 3 trial execution, competitive dynamics with trastuzumab deruxtecan, and biosimilar trastuzumab/pertuzumab pricing pressure.-Fineline Info & Tech
