Neoadjuvant Long-course Chemoradiation Plus PD-1 Blockade for Mid-low Locally Advanced Rectal Cancer

Recruiting now · Phase 2

Conditions studied: Locally Advanced Rectal Cancer

In brief

This is a phase II/III, multi-center, open-label, 3-arm, randomized controlled trial assessing the efficacy and safety of neoadjuvant long-course chemoradiation combined with Tislelizumab (PD-1 inhibitor) and subsequent TME surgery, by comparing assorted endpoints between two experiment groups (Experiment group 1: chemoradiation+concurrent PD-1 inhibitor; Experiment group 2: chemoradiation+sequential PD-1 inhibitor) with a control group (chemoradiation only).
