Camrelizumab (SHR-1210) with carboplatin and albumin-binding paclitaxel in patients with metastatic or recurrent cervical cancer: An open-label, phase 2 trial

Aims: This study evaluates the safety and preliminary antitumor efficacy of camrelizumab with albumin-binding paclitaxel and cisplatin as first-line therapy for patients with recurrent or metastatic cervical carcinoma. Methods and Material: In this phase 2, open-label, prospective study, 35 patients with recurrent or metastatic cervical carcinoma with no previous systemic chemotherapy were included. The patients were treated with a maximum of six cycles of camrelizumab on day 1, albumin-binding paclitaxel, and carboplatin on day 2, every 3 weeks, followed by camrelizumab once every 3 weeks. The primary outcomes were objective response rate (ORR) and disease control rate (DCR). Secondary outcomes were duration of response (DoR) and safety. Furthermore, 27 patients were included in the per-protocol set for efficacy analysis, whereas for the safety analysis, all patients were included. Results: The median follow-up was 4.53 months, and the complete response, partial response, and stable disease were also achieved in 4 (14.81%), 6 (22.22%), and 13 (48.15%) patients. The ORR and DCR were 40.00% (95% confidence interval: 21.13–61.33%) and 92.00% (73.97–99.01%), respectively. The median DoR was 6.70 months. In addition, the most common adverse events (AEs) were reactive cutaneous capillary endothelial proliferation (RCCEP) (23, 65.71%), gastrointestinal reaction (8, 22.86%), and fever (8, 22.86%). Grade 3 AEs included 5 (14.29%) myelosuppression, and grade 4 AEs included 1 (2.86%) RCCEP and 1 (2.86%) bladder inflammation. Conclusions: Combination therapy of camrelizumab and albumin-bound paclitaxel and carboplatin shows promising efficacy and manageable toxicities in patients with recurrent or metastatic cervical cancer.
