PD-1 Antibody Combined With COX Inhibitor in MSI-H/dMMR or High TMB Colorectal Cancer (PCOX)
October 15, 2023 updated by: Yanhong Deng, Sun Yat-sen University
PD-1 Antibody Combined With COX Inhibitor in MSI-H/dMMR or High TMB Colorectal Cancer: a Single Arm Phase II Study
PD-1(programmed death protein 1)antibody has been to approved in patients with MSI-H/dMMR advanced cancer and has achieved significant efficacy.
It is reported that the objective response rate of Pembrolizumab and Nivolumab are 40% and 31.1% in MSI-H/dMMR (microsatellite instability-high/deficiency mismatch repair )colorectal cancer.
What's more, most of the patients who had response for PD-1 antibody achieved a long duration of disease control.
However, not all patients with MSI-H/dMMR was sensitive to PD-1 antibody despite it is a biomarker for PD-1 antibody treatment.
There were about 50-60% of patients with MSI-H/dMMR were insensitive and we don't know why.
What's more, it's reported that tumor mutation burden (TMB) may be another biomarker of response to PD-1 therapy.
COX (cyclooxygenase)inhibitor has been proved to prevent adenomas in colorectal and it is safe for most of the patients.
Preclinical models also showed that COX inhibitor could act with PD-1 antibody in mice and control disease progress.
So, this study aims to evaluated efficacy and safety of combination of PD-1 antibody and COX inhibitor in patients with MSI-H/dMMR or high tumor mutation burden colorectal cancer.

Detailed Description
This is a single arm, phase two study.
Eligible patients with advanced MSI-H/dMMR colorectal cancer were assigned to receive BAT1306 plus COX inhibitor.
All patients will receive the study regimen every 3 weeks.
Chest/abdomen/pelvic CT with IV contrast will be performed to assess clinical response.
