What this trial studies

This clinical trial evaluates the safety and efficacy of envafolimab, a PD-L1 monoclonal antibody, either alone or in combination with CAPEOX as neoadjuvant therapy for patients with locally advanced colorectal cancer that exhibits microsatellite instability (MSI-H/dMMR). The study aims to address the low responsiveness to traditional neoadjuvant chemotherapy in this patient population, which has shown modest benefits from immunotherapy in preliminary studies. Participants will be closely monitored for treatment outcomes and potential side effects.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 70 with pathologically confirmed rectal cancer at clinical stage T3-4 or T any N1.

Not a fit: Patients with early-stage colorectal cancer (T1-2 N0) or those with distant metastasis may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve outcomes for patients with locally advanced MSI-H/dMMR colorectal cancer.

How similar studies have performed: Preliminary studies have shown promising results for neoadjuvant immunotherapy in similar patient populations, indicating potential for success.
