Camrelizumab Plus Famitinib versus Camrelizumab Alone and Investigator's Choice of Chemotherapy in Recurrent or...

To compare camrelizumab (an anti-PD-1 monoclonal antibody) plus famitinib (a multitarget receptor tyrosine kinase inhibitor) versus camrelizumab and chemotherapy in recurrent or metastatic cervical cancer (R/M CC).

Patients with pretreated R/M CC were randomly assigned to receive camrelizumab (200 mg intravenously once every 3 weeks) plus famitinib (20 mg orally once daily), camrelizumab, or investigator's choice of chemotherapy. The primary end point was comparison of objective response rate (ORR) per blinded independent central review (BICR) for camrelizumab-famitinib versus camrelizumab in the intention-to-treat population.

Overall, 105, 54, and 35 patients received camrelizumab-famitinib, camrelizumab, and chemotherapy, respectively. As of April 21, 2023, ORR per BICR was significantly improved with camrelizumab-famitinib compared with camrelizumab (41.0% [95% CI, 31.5 to 51.0] v 24.1% [95% CI, 13.5 to 37.6]; difference, 16.9% [95% CI, 2.1 to 31.7]; one-sided P = .0181). Per investigator, ORR with camrelizumab-famitinib was 42.9% (95% CI, 33.2 to 52.9), notably higher than 22.2% (95% CI, 12.0 to 35.6) with camrelizumab and 14.3% (95% CI, 4.8 to 30.3) with chemotherapy. Median progression-free survival per investigator was prolonged with camrelizumab-famitinib than camrelizumab and chemotherapy (8.1 months [95% CI, 6.2 to 12.4] vs 4.1 months [95% CI, 2.1 to 5.1] and 2.9 months [95% CI, 2.0 to 6.2]). Median overall survival with camrelizumab-famitinib, camrelizumab, and chemotherapy, as of October 19, 2023, was 20.2 months (95% CI, 15.3 to not reached [NR]), 14.9 months (95% CI, 12.6 to NR), and 13.9 months (95% CI, 7.4 to 20.0), respectively. Eighty-nine (84.8%), eight (15.1%), and 18 (60.0%) patients who received camrelizumab-famitinib, camrelizumab, and chemotherapy, respectively, experienced grade ≥3 treatment-related adverse events.

Camrelizumab plus famitinib improved antitumor activity while exhibiting a manageable safety profile in patients with pretreated R/M CC, potentially offering a novel treatment option.
