HuA21 combined with trastuzumab and chemotherapy in HER2-positive advanced gastric/GEJ adenocarcinoma: Phase Ib/II dose-escalation and expansion study (CTR20240640)
(ESMO 2025)
- P1/2 | "Methods Integrated Ib/II trial: Phase Ib (3+3 dose-escalation) evaluated HuA21 (20/30 mg/kg Q3W) + trastuzumab (8 mg/kg loading dose followed by 6 mg/kg Q3W), capecitabine (1000 mg/m 2 BID D1–14), and oxaliplatin (130 mg/m 2 Q3W). Conclusions HuA21 30 mg/kg + trastuzumab/CT showed numerically higher ORR (80.8%) and lower SAEs (6.7% vs 23.3%) versus 20 mg/kg, with PK supporting dose linearity. This regimen demonstrates promising efficacy/safety, establishing 30 mg/kg as RP3D for phase III evaluation in HER2-positive GC/GEJ."
