Official title

A Prospective Single-arm Phase Ib/II Study on the Safety and Efficacy of Fruquintinib Plus Chidamide and Sintilimab in the Third and Later Line Treatment of MSS/pMMR Metastatic Colorectal Cancer

Overview

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.

Interventions

  • Drug Fruquintinib
    Fruquintinib: 5mg qd, po, 2 weeks on/1 week off, q3w, or 3mg qd, po, q3w.
  • Drug Sintilimab
    Sintilimab: 200mg, iv, d1, q3w.
  • Drug Chidamide
    Chidamide: 30mg/m2, po, biw.

Primary outcome measures

  • Progress-free Survival(PFS) [Time frame: 24 months]
Secondary outcome measures (4)
  • Objective response rate (ORR) [Time frame: 24 months]
  • Overall Survival (OS) [Time frame: 24 months]
  • Disease control rate (DCR) [Time frame: 24 months]
  • Duration of response (DoR) [Time frame: 24 months]
