Abstract

Pembrolizumab plus chemotherapy with or without bevacizumab demonstrated prolonged progression-free survival (PFS) and overall survival (OS) versus chemotherapy in patients with persistent, recurrent, or metastatic cervical cancer in the phase 3, randomized, double-blind, placebo-controlled KEYNOTE-826 study. We report outcomes in patients enrolled in Japan. Patients received pembrolizumab 200 mg or placebo Q3W for up to 35 cycles plus chemotherapy (paclitaxel 175 mg/m2 + cisplatin 50 mg/m2 or carboplatin AUC 5) with or without bevacizumab 15 mg/kg. Dual primary endpoints were PFS per RECIST v1.1 by investigator assessment and OS in the global population; these were evaluated in patients with tumors with PD-L1 combined positive score (CPS) ≥1, all-comers, and PD-L1 CPS ≥10. Fifty-seven patients from Japan were randomized (pembrolizumab plus chemotherapy, n = 35; placebo plus chemotherapy, n = 22). Pembrolizumab plus chemotherapy improved PFS versus placebo plus chemotherapy in patients with PD-L1 CPS ≥1 (n = 51; hazard ratio [HR; 95% CI], 0.36 [0.16–0.77]), all-comers (n = 57; 0.45 [0.22–0.90]), and patients with PD-L1 CPS ≥10 (n = 25; 0.36 [0.12–1.07]). HRs (95% CI) for OS were 0.38 (0.14–1.01), 0.41 (0.17–1.00), and 0.37 (0.10–1.30), respectively. Incidence of grade 3–5 AEs was 94% in the pembrolizumab group and 100% in the placebo group. Consistent with findings in the global KEYNOTE-826 study, pembrolizumab plus chemotherapy with or without bevacizumab may prolong survival versus placebo plus chemotherapy with or without bevacizumab and had a manageable safety profile in Japanese patients with persistent, recurrent, or metastatic cervical cancer.
