Fixed Duration vs Continuous Anti-CD38 Antibody Therapy Among Transplant Ineligible Older Adults With Newly-Diagnosed Multiple Myeloma

Currently, daratumumab or isatuximab are given continuously (non-stop), along side lenalidomide, and dexamethasone as part of multiple myeloma treatment. are given continuously (non-stop). Recent observations suggest that stopping daratumumab or isatuximb after about a year and a half of treatment may work just as well as giving them continuously with lenalidomide and dexamethasone. Sometimes, bortezomib is also given. This study is being done to answer the question: is less daratumumab or isatuximab treatment as good as more?
