This randomized phase I/II trial studies the side effects and best dose of pomalidomide and ixazomib when given together with dexamethasone and to see how well pomalidomide and dexamethasone with or without ixazomib works in treating patients with multiple myeloma that does not respond to treatment. Biological therapies, such as pomalidomide and dexamethasone, may stimulate the immune system in different ways and stop cancer cells from growing. Ixazomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. It is not yet known whether pomalidomide and dexamethasone are more effective with or without ixazomib in treating multiple myeloma.
This phase III trial studies how well lenalidomide and dexamethasone works with or without daratumumab in treating patients with high-risk smoldering myeloma. Drugs used in chemotherapy, such as lenalidomide and dexamethasone, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as daratumumab, may induce changes in the body's immune system and may interfere with the ability of tumor cells to grow and spread. Giving lenalidomide and dexamethasone with daratumumab may work better in treating patients with smoldering myeloma.
This phase III trial compares the effect of usual treatment (lenalidomide) to using daratumumab / rHuPH20 plus the usual treatment after stem cell transplantation. This drug combination may help patients live longer after their stem cell transplant. Another purpose of this study is to learn if the presence and amount of minimal residual disease (MRD) can help doctors predict when a patient’s multiple myeloma will get worse. MRD is the name for the small number of cancer cells that remain in the patient even after their multiple myeloma has been treated and they have no symptoms of the disease. Drugs used in chemotherapy, such as lenalidomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with daratumumab / rHuPH20, may induce changes in body’s immune system and may interfere with the ability of tumor cells to grow and spread. Giving lenalidomide and daratumumab / rHuPH20 may work better in treating patients with multiple myeloma compared to lenalidomide alone.
