A Phase II, Prospective, Multicenter Study of Cadonilimab in Combination With FOLFOXIRI and Bevacizumab as First Line Therapy for Metastatic MSS Colorectal Cancer.
Cadonilimab is a first-in-class bispecific, humanized IgG1 antibody targeting PD-1 and CTLA-4, which has the potential to boost immune surveillance in tumors. This was a phase II study of cadonilimab in combination with bevacizumab and FOLFOXIRI as first line therapy for metastatic microsatellite stable (MSS) colorectal cancer. The goal of this clinical trial is to evaluated the efficacy and safety.
• Patients with metastatic pMMR or MSS colorectal adenocarcinoma. Note: MMR or MSI status will be performed locally by an immunohistochemistry (IHC) or PCR based test for eligibility.
• Patients who are naïve to systemic treatment in metastatic setting.
• Patients with previous neoadjuvant or adjuvant chemotherapy (that may have included oxaliplatin or investigational VEGF inhibitors) are eligible if the treatment was completed \> 12 months before inclusion.
• Patients with the presence of at least one lesion with measurable disease as per RECIST 1.1 guidelines. Lesions in previously irradiated areas should not be considered measurable unless they have clearly progressed since the radiotherapy.
• Patients have an Eastern Cooperative Oncology Group (ECOG) performance status 0-1
