Is NCT07108127 recruiting? Yes, currently enrolling (May 2026). This Phase 2 trial studies Trastuzumab biosimilars and pertuzumab biosimilars plus XELOX for rectal cancer.

Phase 2RecruitingPeking Union Medical College HospitalNCT07108127Data as of May 2026

Treatment: Trastuzumab biosimilars and pertuzumab biosimilars plus XELOXThe purpose of this study was to evaluate the complete response rate (CR) of trastuzumab biosimilars and pertuzumab biosimilars combined with oxaliplatin and capecitabine in neoadjuvant treatment of patients with locally advanced (cT3/T4, N+, distance from the lower edge of the tumor to the anal verge ≤12 cm) HER2-positive rectal adenocarcinoma.
