3 Clinical Trials for Various Conditions
This study is being done to evaluate whether the combination of immune therapy and radiation therapy to plasmacytoma that can stimulate the immune system to attack and eliminate the abnormal cells in the bone marrow and perhaps delay or prevent the cancer from worsening. This study will evaluate whether the immune system responds to the combination of radiation with immunotherapy. It is possible that that the combination of immune therapy and radiation may not make any difference in whether or not the patient will develop multiple myeloma in the future.
This randomized phase III trial compares ixazomib citrate, lenalidomide, dexamethasone and zoledronic acid with zoledronic acid alone to see how well they work when given after radiation therapy in treating patients with solitary plasmacytoma of bone. Ixazomib citrate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Lenalidomide may help the immune system kill abnormal blood cells or cancer cells. Dexamethasone is a drug used in chemotherapy that may cause tumor cells to die. Zoledronic acid may prevent bone fractures and reduce bone pain, and may also improve survival. Standard treatment for this cancer is radiation therapy alone. It is not yet known whether ixazomib citrate, lenalidomide, dexamethasone and zoledronic acid or zoledronic acid alone is more effective, and whether adding these treatments after radiation therapy is more effective than radiation therapy alone in treating patients with solitary plasmacytoma of bone.
RATIONALE: Diagnostic procedures, such as magnetic resonance imaging (MRI) and fludeoxyglucose F 18 positron emission tomography (\^18FDG-PET) may help diagnose solitary plasmacytoma. PURPOSE: This clinical trial is studying MRI and \^18FDG-PET to see how well they work in diagnosing patients with solitary plasmacytoma.
