Brief summary

This is a randomized, multi-center, double-blind, placebo-controlled, global, Phase III study to determine the efficacy and safety of durvalumab + Chemoradiotherapy versus Chemoradiotherapy alone as treatment in Women With Locally Advanced Cervical Cancer

Detailed description

Women will be randomized in a 1:1 ratio to receive treatment with concurrent durvalumab + standard of care (SoC) or Placebo + Soc, followed by durvalumab/placebo maintenance for 24 months.

Interventions

BIOLOGICALDurvalumab

IV infusion every 4 weeks

DRUGCisplatin

DRUGCarboplatin

For patients enrolled under CSP v2 and prior - platinum based Standard of Care Chemotherapy administered concurrent with radiation therapy
