The purpose of this study is to determine the effects of daratumumab and lenalidomide without steroids for treating patients with multiple myeloma.

This is an open label, phase 2 study consisting of daratumumab, lenalidomide and dexamethasone, given upfront in newly diagnosed, transplant ineligible patients with myeloma. Patients participating in the study will be recruited from the Wilmot Cancer Institute, University of Rochester in Rochester, New York and all University of Rochester community affiliates.

Patients will be treated with 1800 milligrams of Daratumumab subcutaneously or 16 milligrams/kilograms daratumumab intravenously (IV) weekly for 8 treatments, followed by every 2 weeks for 8 treatments, followed by every 4 weeks. Patients will be treated with 25 milligrams of Lenalidomide days 1-21 out of a 28 day cycle (dose adjustments for creatinine clearance) and 20 milligrams of Dexamethasone at least 60 minutes prior to first infusion of daratumumab. Each cycle consists of 28 days (4 weeks).

Response assessments by International Myeloma Working Group criteria for myeloma will be performed every 4 weeks while on therapy.
