Combining Fruquintinib, Regorafenib, and Sintilimab with Radiotherapy for Advanced Colorectal Cancer

Fruquintinib Combined With Sintilimab ± Radiotherapy for Third-line Treatment of Colorectal Cancer With Liver Metastases: A Randomized, Controlled, Multicenter Phase II Trial

Phase 2 Interventional Shandong Cancer Hospital and Institute · NCT06356584

This study is testing a new combination of three cancer drugs with or without radiation to see if it helps people with advanced colorectal cancer who have already tried other treatments.

What this trial studies

This clinical trial evaluates the effectiveness of a combination therapy involving Fruquintinib, Regorafenib, and Sintilimab, with or without radiotherapy, for patients with metastatic colorectal cancer who have already undergone first- and second-line treatments. The study aims to assess progression-free survival, overall survival, and treatment response rates in patients with both non-liver and liver metastases. Participants will receive tailored treatment protocols based on their specific cancer characteristics, and subgroup analyses will focus on the impact of liver metastases on treatment outcomes.

Who should consider this trial

Good fit: Ideal candidates include patients with histologically confirmed metastatic colorectal adenocarcinoma who have received prior systemic therapies and have measurable lesions.

Not a fit: Patients with other malignancies or those currently participating in other interventional studies may not benefit from this trial.

Why it matters

Potential benefit: If successful, this approach could provide a new effective treatment option for patients with advanced colorectal cancer who have limited options after standard therapies.

How similar studies have performed: While there is existing data on third-line treatments for advanced colorectal cancer, this specific combination therapy approach is novel and has not been extensively tested.
