摘要

Fruquintinib has been recommended for treating refractory metastatic colorectal cancer. This single-arm, phase II study explored for the first time whether fruquintinib combined with capecitabine could be used as a first-line treatment for patients with metastatic colorectal cancer who are intolerant to intravenous chemotherapy. From December 8, 2021, to December 31, 2024, 17 patients were included in the effect analysis who respectively received capecitabine and fruquintinib at a starting dose of 825 mg/m2 twice a day and 4 mg every day (2 weeks followed by 1-week rest) and recorded changes in safety and quality of life; the dosage can be appropriately adjusted according to the protocol to make it tolerable for the patients. The median age was 76 years old; the study achieved a disease control rate of 88.2%, an overall response rate of 17.6%, and a median progression-free survival of 16.3 months (95% CI 9.7–22.9); the overall survival had not been reached. The median quality of life scores and self-assessment of health scores change, respectively, from 42 (IQR 34, 47) to 45 (IQR 41, 57) and from 5 (IQR 4.25, 6.75) to 4 (IQR 3.00, 6.00). There were only 3 events of grade ≥ 3 TRAEs, including one rare case of aortic dissection. Fruquintinib combined with capecitabine has initially shown ideal disease control, safety, and convenience, especially as a first-line treatment for elderly frail patients with metastatic colorectal cancer. Further phase III study is planned to refine this combination. Clinical Trial Number: NCT04866108.
