Ixazomib Citrate, Lenalidomide, Dexamethasone, and Zoledronic Acid or Zoledronic Acid Alone after Radiation Therapy in Treating Patients with Solitary Plasmacytoma of Bone
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.

PRIMARY OBJECTIVES:
I. To assess whether ixazomib (ixazomib citrate), lenalidomide, dexamethasone with zoledronic acid is more promising than zoledronic acid alone in increasing the time before progression to multiple myeloma.
SECONDARY OBJECTIVES:
I. To assess changes in minimal residual disease (MRD) by flow cytometry from study entry, at the completion of treatment, and at 1 year post registration.
II. To assess whether ixazomib, lenalidomide, dexamethasone with zoledronic acid is more promising than zoledronic acid alone in extending overall survival.
III. To examine the pharmacodynamics effects of treatment on biochemical markers of bone formation (osteocalcin bone-specific alkaline phosphatase), resorption (serum CTX), and metabolism (osteoprotegerin [OPG]).
EXPLORATORY OBJECTIVES:
I. To explore the incidence of shifts in bone mineral density classification after 12 months of treatment.
CORRELATIVE SCIENCE OBJECTIVES:
I. To analyze the pathways related to bone metabolism from specimens obtained prior to or following radiation and progression to multiple myeloma.
II. To analyze MRD by sequencing based platform (Sequenta) in peripheral blood prior to the start of adjuvant treatment and completion of adjuvant treatment and compare results to MRD detection by flow cytometry in bone marrow aspirate.
OUTLINE: Patients are randomized to 1 of 2 treatment arms.
ARM I: Patients receive ixazomib citrate orally (PO) on days 1, 8, and 15, lenalidomide PO on days 1-21, dexamethasone PO on days 1, 8, 15, and 22, and zoledronic acid intravenously (IV) over 15 minutes on day 1. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.
ARM II: Patients receive zoledronic acid IV over 15 minutes on day 1. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months until disease progression and then every 6 months for up to 5 years.
