This phase 2 study assesses the efficacy and safety of camrelizumab (an anti-PD-1 antibody) plus famitinib (anti-angiogenic agent) in women with pretreated recurrent or metastatic cervical cancer (ClinicalTrials.gov NCT03827837). Patients with histologically or cytologically confirmed cervical squamous cell carcinoma experiencing relapse or progression during or after 1-2 lines of systemic therapy for recurrent or metastatic disease are enrolled. Eligible patients receive camrelizumab 200mg intravenously on day 1 of each 3-week cycle plus famitinib 20mg orally once daily. The primary endpoint is the objective response rate. Secondary endpoints are duration of response, disease control rate, time to response, progression-free survival, overall survival, and safety. The trial has met pre-specified endpoint. Thirty-three patients are enrolled; median follow-up lasts for 13.6 months (interquartile range: 10.0-23.6). Objective responses are observed in 13 (39.4%, 95% confidence interval [CI]: 22.9-57.9) patients; the 12-month duration of response rate is 74.1% (95% CI: 39.1-90.9). Median progression-free survival is 10.3 months (95% CI: 3.5-not reached) and the 12-month overall survival rate is 77.7% (95% CI: 58.9-88.7). All patients experience treatment-related adverse events; grade >= 3 events occur in 26 (78.8%) patients. Treatment-related serious adverse events and deaths are observed in 9 (27.3%) and 2 (6.1%) patients, respectively. Camrelizumab plus famitinib shows promising antitumor activity with a manageable and tolerable safety profile in patients with pretreated recurrent or metastatic cervical squamous cell carcinoma. This combination may represent a treatment option for this population. Patients with recurrent or metastatic cervical cancer have limited therapeutic options. Here the authors report efficacy and safety of camrelizumab (anti-PD-1 antibody) in combination with famitinib (anti-angiogenic agent) in pre-treated recurrent or metastatic squamous cervical cancer.
