Study of Chemoradiotherapy With or Without Pembrolizumab (MK-3475) For The Treatment of Locally Advanced Cervical Cancer (MK-3475-A18/KEYNOTE-A18/ENGOT-cx11/GOG-3047)

Trial Status: closed to accrual

The purpose of this study is to evaluate the efficacy and safety of pembrolizumab plus concurrent chemoradiotherapy compared to placebo plus concurrent chemoradiotherapy in participants with locally advanced cervical cancer. The primary hypotheses are that pembrolizumab plus concurrent chemoradiotherapy is superior to placebo plus concurrent chemoradiotherapy with respect to progression-free survival and overall survival. Once the study objectives have been met or the study has ended, participants will be discontinued from this study and will be enrolled in an extension study to continue protocol-defined assessments and treatment.
