About this trial

Study Title:

A Prospective, Randomized, Phase II, Multicenter Clinical Study of Serplulimab Combined with Targeted Therapy, Chemotherapy, and Optional Radiotherapy in Advanced Colorectal Cancer

Study Objective:

To explore the efficacy and safety of immune checkpoint inhibitor combined with targeted therapy and chemoradiotherapy in locally advanced unresectable or metastatic colorectal cancer.

Study Population:

Patients with left-sided wild-type, right-sided, or RAS-mutant advanced colorectal cancer who have not received systemic treatment.

Study Endpoints:

Progression-free survival (PFS), objective response rate (ORR), overall survival (OS), safety, and R0 resection rate.

Study Design:

Prospective, randomized Phase II clinical study.

Eligibility criteria

Qualifiers

Age ≥ 18 years, any gender;

Histologically confirmed metastatic colorectal cancer (Stage IV, UICC), with initially unresectable metastases or refusal of surgery;

Primary tumor located in the distal transverse colon, descending colon, sigmoid colon, and rectum, and RAS (KRAS and NRAS) and BRAF wild-type (Cohorts A and B);

Primary tumor located in the cecum, ascending colon, and proximal transverse colon, and RAS (KRAS and NRAS) mutant-type (Cohorts C and D);

Disqualifiers

Pathologically diagnosed with other intestinal tumors, such as gastrointestinal stromal tumors;

No testing for RAS mutation status;

Resectable metastases or patients wishing to undergo metastasectomy;

Prior systemic therapy. Systemic therapy includes all of the following: chemotherapy agents such as fluoropyrimidines, irinotecan, and oxaliplatin, VEGF monoclonal antibodies (e.g., bevacizumab), EGFR monoclonal antibodies (cetuximab or panitumumab), small molecule TKIs, immune checkpoint inhibitors, etc.;
