About
This phase II trial studies the side-effects and anti-cancer effects of giving an autologous or syngeneic stem cell transplant followed by an allogeneic donor stem cell transplant and bortezomib. Patients treated on this trial have newly diagnosed high-risk, relapsed, or refractory multiple myeloma (MM). Giving chemotherapy before an autologous stem cell transplant slows or stops the growth of cancer cells by preventing them from dividing or killing them. Stem cells that were harvested earlier from the patient's blood and frozen are then returned to the patient to replace the blood-forming cells that were destroyed by chemotherapy. Giving chemotherapy and total-body irradiation before an allogeneic donor stem cell transplant also prevents the patient's immune system from rejecting the donor's stem cells. Undergoing an autologous or syngeneic stem cell transplantation followed by an allogeneic donor stem cell transplant and bortezomib may be overall more effective in killing cancer cells.
Full description
PRIMARY OBJECTIVES:
I. Progression-free survival (PFS) at 2 years after the autograft (=< 50% in historic controls).
SECONDARY OBJECTIVES:
I. Overall survival (OS) at 2 years after the autograft.
II. Non-relapse mortality (NRM) at 200 days and 1 year after allograft.
III. Incidence of grades II-IV acute graft-versus-host-disease (GVHD) and chronic extensive GVHD.
IV. Safety of bortezomib maintenance therapy after stem cell transplantation.
OUTLINE:
PERIPHERAL BLOOD STEM CELL (PBSC) MOBILIZATION: Patients undergo PBSC mobilization and collection using the preferred regimens at the participating institution.
CONDITIONING CHEMOTHERAPY AND AUTOLOGOUS OR SYNGENEIC HEMATOPOIETIC STEM CELL TRANSPLANTATION (HSCT): Patients receive high-dose melphalan intravenously (IV) on day -2 followed by an autologous or syngeneic HSCT on day 0.
NON-MYELOABLATIVE ALLOGENEIC HSCT: Beginning 40-180 days after autologous HSCT, patients receive 1 of the following regimens:
MAINTENANCE THERAPY: Beginning 60-120 days after allogeneic HSCT, patients receive bortezomib subcutaneously (SC) on days 1 and 4 of 14-day cycles for 9 months or for up to 18 cycles in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months for 1 year and then annually for up to 5 years.

Inclusion criteria
Newly diagnosed patients must have received induction therapy (e.g., vincristine, doxorubicin, dexamethasone [VAD], thalidomide/dexamethasone) for a minimum of 4 cycles
Must have the capacity to give informed consent
Must have an human leukocyte antigen (HLA) genotypically identical sibling or a phenotypically matched relative or, at a minimum, a high likelihood of identifying an HLA-matched unrelated donor; the determination of availability of a suitable unrelated donor may be based on a World-Book search
In addition, patients must meet at least one of the criteria A-I (A-G at time of diagnosis or pre-autograft):
DONOR: HLA genotypically identical sibling or phenotypically matched relative OR
DONOR: HLA phenotypically matched unrelated donor (according to Standard Practice HLA matching criteria, Grade #2.1)
Exclusion criteria
Recurrent or non-responsive (less than partial response [PR]) MM after at least two different lines of conventional chemotherapy
Progressive MM after a previous autograft
Life expectancy severely limited by disease other than malignancy
Seropositive for the human immunodeficiency virus (HIV)
Females who are pregnant or breastfeeding
Fertile men or women unwilling to use contraceptive techniques during and for 12 months following treatment
Patients with active non-hematological malignancies (except non-melanoma skin cancers) or those with non-hematological malignancies (except non-melanoma skin cancers) who have been rendered with no evidence of disease, but have a greater than 20% chance of having disease recurrence within 5 years; this exclusion does not apply to patients with non-hematologic malignancies that do not require therapy
Patients with fungal infection and radiological progression after receipt of amphotericin B or active triazole for greater than 1 month
Patients with the following organ dysfunction:
Patient with poorly controlled hypertension and on multiple antihypertensives
Patients with current >= grade 2 peripheral neuropathy
Patient has an active bacterial or fungal infection unresponsive to medical therapy

DONOR: Pregnancy
DONOR: Infection with HIV
DONOR: Inability to achieve adequate venous access
DONOR: Known allergy to G-CSF
DONOR: Current serious systemic illness
DONOR: Failure to meet FHCRC criteria for stem cell donation
DONOR: Age < 12 years
DONOR: A positive anti-donor cytotoxic crossmatch
DONOR: Patient and donor pairs must not be homozygous at mismatched allele
