Bortezomib, Melphalan, and Total-Body Irradiation Before Stem Cell Transplant in Treating Patients With Multiple Myeloma


About this study

This phase I/II trial studies the side effects and best dose of bortezomib when given together with melphalan, and total-body irradiation before stem cell transplant and to see how well it works in treating patients with multiple myeloma. Giving chemotherapy and total-body irradiation before a stem cell transplant stops the growth of cancer cells by stopping them from dividing or killing them. The stem cells that were collected from the patient''s blood or bone marrow are returned to the patient to replace the blood-forming cells that were destroyed by the chemotherapy and total-body irradiation.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Inclusion Criteria:

  • Serum creatinine ≤ 2 mg/dL
  • Serum total bilirubin ≤ 1.5 X upper limit of normal (ULN)
  • Platelet count ≥ 30,000/μL
  • Hemoglobin ≥ 8.0 g/dL
  • Diagnosis of myeloma for which autologous stem cell transplant is being considered
  • Measurable disease of multiple myeloma at the time of baseline values for disease assessment as defined by at least one of the following:
    • Serum monoclonal protein ≥ 1.0 g/dL
    • ≥ 200 mg of monoclonal protein in the urine on 24 hour electrophoresis
    • Serum immunoglobulin free light chain ≥ 10 mg/dL AND abnormal serum immunoglobulin kappa to lambda free light chain ratio
    • Bone marrow plasma cells ≥ 30%
  • Note:
    • For patients with no relapse prior to transplant, measurable disease at the time of diagnosis
    • For patients who have had a disease relapse prior to transplant, measurable disease at the time of the most recent relapse immediately prior to transplant.
    • If the patient had treatment for the relapsed disease prior to transplant, the patient must have measurable disease at the time of relapse prior to this therapy
  • Patient is considered for autologous stem cell transplantation with full dose melphalan (200 mg/m^2)
  • Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0, 1 or 2
  • Recovered from non-hematological toxicity of previous chemotherapy (excludes grade 1 neurotoxicity)
  • Voluntary written informed consent before performance of any study-related procedure not part of normal medical care, with the understanding that consent may be withdrawn by the subject at any time without prejudice to future medical care
  • Ejection fraction ≥ 45%
  • Corrected pulmonary diffusion capacity of greater than or equal to 50%
  • Forced expiratory volume in one second (FEV1) ≥ 50%
  • Forced vital capacity (FVC) ≥ 50%
  • Negative pregnancy test performed ≤ 7 days prior to registration, for women of childbearing potential only
  • Willing to return to Mayo Clinic Rochester, for treatment and follow-up
    • 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
  • Willing to provide blood and bone marrow samples for correlative research purposes

Exclusion Criteria:

  • Prior autologous or allogeneic bone marrow/peripheral blood stem cell transplant
  • More than two prior regimens for therapy of MM
  • Myocardial infarction within 6 months prior to enrollment, or has New York Heart Association (NYHA) class III or IV heart failure, uncontrolled angina, severe uncontrolled ventricular arrhythmias, or electrocardiographic evidence of acute ischemia or active conduction system abnormalities; NOTE: prior to study entry, any electrocardiogram (ECG) abnormality at screening has to be documented by the investigator as not medically relevant
  • Seroreactivity for human immunodeficiency virus (HIV), human T-cell lymphotrophic virus (HTLV) I or II, hepatitis B virus (HBV), hepatitis C virus (HCV)
  • Other active malignancy < 2 years prior to registration; EXCEPTIONS: non-melanotic skin cancer or carcinoma-in-situ of the cervix or low-risk prostate cancer after curative therapy
    • NOTE: If there is a history of prior malignancy, they must not be receiving other specific treatment for their cancer
  • Any of the following:
    • Pregnant women or women of reproductive capability who are unwilling to use effective contraception (2 effective methods of contraception, at the same time) from the time of signing the informed consent through 30 days after the last dose of study treatment, OR unwilling to agree to completely abstain from heterosexual intercourse
    • Nursing women
    • Men who are unwilling to use a condom (even if they have undergone a prior vasectomy) while having intercourse with any woman, while taking the drug and for 30 days after stopping treatment
    • Unwilling to agree to completely abstain from heterosexual intercourse
  • Other co-morbidity, which would interfere with patient's ability to participate in the trial, e.g. uncontrolled infection, uncompensated lung disease or psychiatric illness
  • 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
  • Known allergies to any of the components of the investigational treatment regimen or required ancillary treatments
  • Patient has ≥ grade 2 peripheral neuropathy
  • Participation in clinical trials with other investigational agents not included in this trial, within 14 days of the start of this trial and throughout the duration of this trial
