Official title

An Open-label, Multi-centered, Two-stage Clinical Study of Short-course Radiotherapy Followed by Fruquintinib Plus Sintilimab vs Bevacizumab Plus Capecitabine in the First Line Treatment of Advanced mCRC Patients Unfit for Intense Therapy

Overview

The aim of this study is to evaluate the efficacy and safety of short course radiotherapy followed by fruquintinib combined with Sintilimab as the first-line treatment of advanced mCRC compared to bevacizumab combined with capecitabine in patients unfit for intensive therapy.

Detailed description

Anti-angiogenic therapy combined with immune checkpoint inhibitors in advanced mCRC has shown promising efficacy with acceptable toxicities. Radiotherapy may reshape the tumor immune microenvironment, thereby improving the efficacy of subsequent anti angiogenic drugs combined with immunotherapy.

The study is a prospective, multi-centered, two-stage clinical study with 220 unresectable advanced mCRC patients unfit for oxaliplatin or irinotecan-based intensive chemotherapy enrolled. In phase 1b, 20 patients will be recruited and the efficacy and safety of SCRT followed by fruquintinib plus sintilimab will be explored. In phase 2, 200 patients will be randomized and the efficacy and safety will be compared between SCRT followed by fruquintinib plus sintilimab and capecitabine plus bevacizumab.

Interventions

  • Drug Experimental
    SCRT: 5\*5Gy for 5 days, after a one-week rest, with fruquintinib plus sintilimab followed; Fruquintinib: qd po, 4mg/d, 2weeks on/1 week off, q3w; Sintilimab: intravenous infusion, 200mg, on day 1, q3w.
  • Drug Active Comparator
    Capecitabine: bid po, 1000mg/m², on days 1-14, q3w; Bevacizumab: intravenous infusion, 7.5mg/kg, on day 1, q3w.

Primary outcome measures

  • Phase 1b - Objective Response Rate (ORR) [Time frame: From randomization until disease progression (up to approximately 3-5 years)]
  • Phase 2 - Progression-free Survival (PFS) [Time frame: From randomization until disease progression (up to approximately 3-5 years)]
Secondary outcome measures (3)
  • Tolerability and safety of study regimens [Time frame: From randomization until the end of treatment (up to approximately 3-5 years)]
  • Disease Control Rate (DCR) [Time frame: From randomization until disease progression (up to approximately 3-5 years)]
  • Overall Survival OS) [Time frame: From randomization until disease progression (up to approximately 3-5 years)]
