Fruquintinib Combined With Sintilimab ± Radiotherapy for Third-line Treatment of Colorectal Cancer With Liver Metastases: A Randomized, Controlled, Multicenter Phase II Trial
Status: Recruiting
Location: See location...
Intervention Type: Drug, Radiation
Study Type: Interventional
Study Phase: Phase 2
SUMMARY
Colorectal cancer (CRC) is a significant cause of morbidity and mortality worldwide. Its early clinical manifestations are often subtle, leading to late-stage diagnosis in about 30% of cases with distant metastases. Liver metastases are widespread and associated with poor prognosis, especially in terms of response to immunotherapy. This prospective study will evaluate the efficacy of combined therapy involving sintilimab, fruquintinib, and radiotherapy in CRC with liver metastases. The primary objectives are to assess progression-free survival, overall survival, and treatment response rates. This study aims to provide valuable insights into optimizing third-line and subsequent therapies for CRC with liver metastases by elucidating the efficacy and safety of this combined treatment approach.
• Previously received standard first- and second-line systemic anti-tumor therapy
• At least one measurable lesion as defined by RECIST 1.1 criteria
• Access to tumor samples for biomarker assessment
• Expected survival of ≥3 months
• Normal function of major organ systems (within 14 days before enrollment)
• No systemic corticosteroid treatment within 7 days before treatment initiation, excluding physiological corticosteroid replacement therapy.
• Fertile males or females with the potential for pregnancy must use highly effective contraception methods during the trial.

Treatments
Experimental: Immunotherapy, targert therapy, and radiotherapy
For liver oligometastases, high-dose stereotactic body radiation therapy (SBRT) irradiation will be administered to all lesions with a dose fractionation pattern of 40-50 Gy/5F, 60-70 Gy/10F, or 65 Gy/13F. For multiple liver metastases, SBRT plus low-dose radiation therapy (LDRT) will be performed to all lesions. One or more suitable lesions (which will be selected by the physician based on proximity to organs at risk) will undergo SBRT with a dose fractionation pattern of 40-50 Gy/5F, 60-70 Gy/10F, or 65 Gy/13F, and the remaining lesions will undergo LDRT at a total dose of 1-10 Gy at 0.5-2.0 Gy/F. Extrahepatic lesions will be not treated with radiotherapy. Targeted therapy and immunotherapy will be administered one week after the end of radiation therapy. A 21-day treatment cycle of sintilimab (200 mg, D1, once every 3 weeks) will be given intravenously on day 1 of each cycle, and fruquintinib will be given on days 1 to 14.
Active_comparator: Immunotherapy and targert therapy
A 21-day treatment cycle of sintilimab (200 mg, D1, once every 3 weeks) will be given intravenously on day 1 of each cycle, and fruquintinib will be given on days 1 to 14.
Active_comparator: Targert therapy
Treatment with fruquintinib (5 mg, po, D1-21, once every 4 weeks) will be given on days 1 through 21 in a 28-day treatment cycle.
