Skin lesions can be used if the area is >= 2 cm in at least one diameter and measured with a ruler

• Negative pregnancy test done =< 7 days prior to registration, for women of childbearing potential only
• Willing to return to consenting Mayo Clinic institution for follow-up during the Active Monitoring Phase of the study; Note: during the Active Monitoring Phase of a study (i.e., active treatment and observation), participants must be willing to return to the consenting institution for follow-up
• Recovered (i.e., < grade 1 toxicity) from the reversible effects of prior antineoplastic therapy
• Arms A - D only: Patients should be proteasome inhibitor naive (including bortezomib and carfilzomib) OR have received less than 6 cycles of therapy with a bortezomib or carfilzomib containing regimen and were not refractory to the bortezomib or carfilzomib based regimen (less than a PR or progression on or within 60 days of discontinuation)
• Arm E only: Negative hepatitis B test (defined by a negative test for hepatitis B surface antigen [HBsAg], or antibodies to hepatitis B surface and/or core antigens [antiHBs or antiHBc]) (added as of addendum 9); Note: patients with serologic findings suggestive of hepatitis B virus (HBV) vaccination (antiHBs positivity as the only serologic marker) AND a known history of prior HBV vaccination do not need to be tested for HBV deoxyribonucleic acid (DNA) by polymerase chain reaction (PCR); those who are PCR positive will be excluded

Exclusion Criteria:

  • Anthracyclines =< 14 days prior to registration
  • High dose corticosteroids, immune modulatory drugs (thalidomide or lenalidomide) =< 7 days prior to registration
• Prior therapy with any proteasome inhibitor other than bortezomib, carfilzomib, or ixazomib
• Concomitant high dose corticosteroids other than what is part of treatment protocol (concurrent use of corticosteroids); EXCEPTION: patients may be on chronic steroids (maximum dose 20 mg/day prednisone equivalent) if they are being given for disorders other than myeloma, i.e., adrenal insufficiency, rheumatoid arthritis, etc
• Diagnosed or treated for another malignancy within 2 years before study enrollment or previously diagnosed with another malignancy and have any evidence of residual disease; patients with nonmelanoma skin cancer or carcinoma in situ of any type are not excluded if they have undergone complete resection

• Other co-morbidity which would interfere with patient's ability to participate in trial, e.g. uncontrolled infection, uncompensated heart or lung disease
• Other concurrent chemotherapy, radiotherapy, or any ancillary therapy considered investigational; NOTE: bisphosphonates are considered to be supportive care rather than therapy, and are thus allowed while on protocol treatment
• Patient has >= grade 3 peripheral neuropathy, or grade 2 with pain on clinical examination during the screening period
• Major surgery within 14 days before study registration
• Systemic treatment with strong inhibitors of cytochrome P450, family 1, subfamily A (CYP3A) inducers (rifampin, rifapentine, rifabutin, carbamazepine, phenytoin, phenobarbital), or use of Ginkgo biloba or St. John's wort within 14 days before the first dose of study treatment
• Evidence of current uncontrolled cardiovascular conditions, including cardiac arrhythmias, congestive heart failure, angina, or myocardial infarction within the past 6 months; Note: prior to study entry, any electrocardiogram (ECG) abnormality at screening must be documented by the investigator as not medically relevant
