💬In plain words
What the trial is, and whether it could suit you
The prognosis of most patients with unresectable locally advanced or metastatic colorectal cancer (CRC) remains poor despite the advancements in chemotherapy and target therapy.
CAPability-01 trial investigated the potential efficacy of combining the programmed cell death protein-1 (PD-1) monoclonal antibody sintilimab with the histone deacetylase inhibitor (HDACi) chidamide with or without the anti-vascular endothelial growth factor (VEGF) monoclonal antibody bevacizumab in patients with unresectable chemotherapy-refractory locally advanced or metastatic microsatellite stable/proficient mismatch repair (MSS/pMMR) colorectal cancer.
Based on the previous findings of CAPability-01, we will further evaluate the efficacy and safety of sintilimab and chidamide in combination with fruquintinib in the same setting.
