Patients and Methods: In this multicenter, open-label, phase Ib trial (NCT04551950), patients with P/R/M cervical cancer received bintrafusp alfa 2,400 mg once every 3 weeks plus cisplatin or carboplatin plus paclitaxel with (Cohort 1A; n = 8) or without (Cohort 1B; n = 9) bevacizumab; patients with locally advanced cervical cancer received bintrafusp alfa 2,400 mg every 3 weeks plus cisplatin plus radiation, followed by bintrafusp alfa monotherapy maintenance (Cohort 2; n = 8). The primary endpoint was safety; secondary endpoints included efficacy (including objective response rate) and pharmacokinetics. Results: At the data cutoff of April 27, 2022, patients in Cohorts 1A, 1B, and 2 had received bintrafusp alfa for a median duration of 37.9, 31.1, and 16.7 weeks, respectively. Two dose-limiting toxicities (grade 4 amylase elevation and grade 3 menorrhagia) unrelated to bintrafusp alfa were observed in Cohort 1B and none in other cohorts. Most treatment-emergent adverse events of special interest were grades 1–2 in severity, most commonly anemia (62.5%–77.8%) and bleeding events (62.5%–77.8%). Objective response rate was 75.0% [95% confidence interval (CI), 34.9–96.8], 44.4% (95% CI, 13.7–78.8), and 62.5% (95% CI, 24.5–91.5) in Cohorts 1A, 1B, and 2, respectively. Conclusions: Bintrafusp alfa had manageable safety and demonstrated clinical activity, further supporting the investigation of TGFβ/PD-L1 inhibition in human papillomavirus–associated cancers, including cervical cancer.
