This is a multicenter, open-label, Phase 1/2 study to determine the recommended dose and regimen of durvalumab in combination with lenalidomide (LEN) with or without dexamethasone (dex) in subjects with Newly diagnosed multiple myeloma (NDMM). The study will consist of a dose-finding phase as well as a parallel dose-expansion phase to determine the optimal regimen.

Study Start Date: April 2016

Estimated Completion Date: August 2024
