Neoadjuvant Chemoradiotherapy Plus Sintilimab for Intermediate/High Immunoscore Locally Advanced Rectal Cancer

Is NCT05450029 recruiting? Yes, currently enrolling (Jun 2026). This Phase 2 trial studies Sintilimab for rectal cancer.

Phase 2RecruitingYanhong DengNCT05450029Data as of Jun 2026Location: China

Treatment: SintilimabImmunoscore has been reported to be superior to microsatellite instability staging in predicting the disease-specific recurrence and survival for patients with colorectal cancer. However, the relationship between Immunoscore and its impact on patient's response to PD-1 blockade remains to be elucidated. This phase II, prospective, open label study is designed to evaluate the efficacy and safety of combination neoadjuvant chemoradiotherapy (nCRT) with the anti-PD-1 antibody sintilimab for intermediate/high Immunoscore locally advanced rectal cancer.
