- Abstract
Concurrent inhibition of angiogenesis and immune checkpoints represents a potent therapeutic approach. We conducted a phase 2, multicenter, basket study to assess the efficacy and safety of combination therapy of famitinib (anti-angiogenic agent) plus camrelizumab (PD-1 antagonist) in patients with metastatic solid tumors across 11 cohorts (this study was registered at Clinicaltrials.gov[NCT04346381]). This report focuses on the cohort of patients with metastatic or advanced colorectal cancer. Eligible patients, who had previously received ≥2 lines of systemic treatments for their metastatic disease, were treated with famitinib (20 mg once daily) in combination with camrelizumab (200 mg intravenously every 3 weeks). The primary endpoint was the objective response rate, with secondary endpoints encompassing progression-free survival, overall survival, duration of response, safety and exploratory biomarkers. A total of 44 patients were enrolled and treated. With a median follow-up time of 9.46 months (range 2.0–22.5 months), objective responses were observed in 6 patients (13.6%; 95% confidence interval [CI], 5.2%–27.4%), all of whom had rectal cancer. The median duration of response is 6.2 months (95% CI, 2.3–10.6 months). Median progression-free survival was 3.3 months (95% CI, 2.1–4.1 months), and median overall survival was 10.9 months (95% CI, 7.6–15.2 months). Among the 44 patients, 29 (65.9%) experienced grade 3 or 4 treatment-related adverse events, predominantly hypertension and proteinuria. In conclusion, the combination of famitinib and camrelizumab demonstrates promising antitumor activity with a manageable safety profile in metastatic colorectal cancer patients. Further research is warranted to confirm and extend these findings.
