Testing the Investigational Agent Combination of Daratumumab, Bortezomib, and Dexamethasone Compared to the Usual Treatment of Cyclophosphamide, Bortezomib, and Dexamethasone in Newly Diagnosed Multiple Myeloma Patients With Kidney Failure

This study is being done to answer the following question: Can the addition of daratumumab-hyaluronidase to the usual treatment of bortezomib and dexamethasone improve kidney function in patients who are newly diagnosed with multiple myeloma and have kidney failure? This study is being done because the investigators want to find out if this approach is better or worse than the usual approach for the participant's newly diagnosed multiple myeloma. The usual approach is defined as care most people get for multiple myeloma. If the participant decides to take part in this study, they will either get the study medications daratumumab-hyaluronidase, bortezomib, and dexamethasone for four months (4 cycles), or the typical medications used to treat your cancer (cyclophosphamide, bortezomib, and dexamethasone) for 4 months (4 cycles). After the participant finishes their study treatment, their doctor will continue to follow their condition for 10 years to watch them for side effects and monitor their disease status. Their doctor will follow up with them every 3 months for years 1 and 2 and then every 6 months for years 3 through 10.
