40 InnovaTV 301/ENGOT-cx12/GOG-3057: tisotumab vedotin vs investigator’s choice chemo in second- or third-line recurrent or metastatic cervical cancer

Abstract

Introduction/Background Doublet chemotherapy (paclitaxel plus either platinum or topotecan) with bevacizumab (if eligible) is recommended for first‐line treatment of recurrent or metastatic cervical cancer (r/mCC; Tewari 2014). In the second‐line setting, there are limited data for available treatment options. Tisotumab vedotin (TV) is an investigational antibody‐drug conjugate directed to tissue factor. In the phase 2 pivotal trial (innovaTV 204/ENGOT‐cx6/GOG‐3023) in r/mCC patients with disease progression on or after chemotherapy, TV demonstrated clinically meaningful and durable activity (objective response rate [ORR]: 24%; median duration of response [DOR]: 8.3 months) with a manageable and tolerable safety profile. Most adverse events associated with TV were mild to moderate. These findings support further investigation of TV in patients with r/mCC who progress on first‐line treatment options. Methodology innovaTV 301/ENGOT‐cx12/GOG‐3057 (NCT04697628) is a global, randomized, open‐label, phase 3 trial evaluating efficacy and safety of TV in patients with previously treated r/mCC. Eligible patients must be ≥18 years, have r/mCC, and have progressed after receiving 1‐2 prior lines of therapy (either standard of care systemic chemotherapy doublet or platinum‐based therapy with bevacizumab, if eligible). Approximately 482 patients will be randomized 1:1 to receive 21‐day cycles of TV (2.0 mg/kg IV once every 3 weeks) or investigator's choice of chemotherapy: topotecan, vinorelbine, gemcitabine, irinotecan, or pemetrexed. The primary endpoint is overall survival. Key secondary endpoints are progression‐free survival, ORR, time to response, DOR, safety, and quality of life outcomes. The study is enrolling and will have sites in the USA, Europe, Japan, Latin America, Taiwan, Singapore, and South Korea.
