Preoperative Short Course Radiotherapy With Chemotherapy and Camerelizumab in Locally Advanced Rectal Cancer
- Registration Number
- NCT04231552
- Lead Sponsor
- Wuhan Union Hospital, China
- Brief Summary
This is a open-label, single-arm study to investigate the safety and efficacy of consolidative chemotherapy with camrelizumab, an anti-PD-1 antibody drug following short course radiotherapy and subsequent surgical therapy in patients with locally advanced resectable rectal cancer.
- Detailed Description
Patients with locally advanced rectal cancer (cT3-4 or N+) are assigned to receive preoperative 5 × 5 Gy irradiation over 5 days with consolidation chemotherapy consisting two cycles of CAPOX chemotherapy and camrelizumab, an anti-PD-1 antibody drug for two cycles. Subsequent surgical therapy is performed to evaluate the safety and efficacy.
