Clinical Trial Summary

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.

Description:

PRIMARY OBJECTIVES:

I. To determine the maximum tolerated dose (MTD) of bortezomib that can be added to high dose melphalan and low dose total body irradiation as part of conditioning chemotherapy for myeloma. (Phase I) II. To determine the efficacy of the bortezomib added to high dose melphalan and low dose total-body irradiation (TBI) in patients with myeloma undergoing stem cell transplantation, as defined by achievement of complete response (CR). (Phase II)

SECONDARY OBJECTIVES:

I. To examine the toxicities associated with addition of bortezomib to high dose melphalan and TBI in patients with multiple myeloma (MM).

II. To determine the progression free rate at 1 and 2 years.

TERTIARY OBJECTIVES:

I. To determine the proportion of patients achieving a minimal residual disease (MRD) negative status.

II. To assess the HevyLite assay prior to and during treatment.

OUTLINE: This is a phase I, dose-escalation study of bortezomib followed by a phase II study.

CONDITIONING REGIMEN: Patients receive bortezomib intravenously (IV) on days -5 and -2, TBI twice daily (BID) on days -5 and -2, and melphalan IV over 1 hour on days -4 and -3.

TRANSPLANT: Patients undergo autologous bone marrow or peripheral blood stem cell transplant on day 0.

After completion of study treatment, patients are followed up at 100 days and then every 90 days for up to 3 years.

• 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

• 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

• 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
