Nivolumab-ipilimumab and Chemoradiation for Cervical Cancer

Overview

A total of 112 patients with locally advanced cervical cancer will be randomized 1:1 to standard therapy with cisplatin-based chemoradiation or nivolumab-ipilimumab induction followed by cisplatin-based chemoradiation. The primary outcome will be 3-year disease-free survival.

Description

Patients with adenocarcinoma or squamous cell carcinoma of the cervix, FIGO Stage IB2-IB3 node positive or Stage IIB-IVA will be randomized to conventional cisplatin-based chemo-radiation or to 4 cycles of induction immunotherapy with nivolumab 1mg/kg and ipilimumab 3mg/kg every 3 weeks, followed by cisplatin chemo-radiation with concurrent nivolumab 240mg every 2 weeks. Primary outcome will be 3-year progression-free survival.

• At least 1 lesion, not previously irradiated, that qualifies as a RECIST 1.1 Target Lesion at baseline.

Exclusion Criteria:
