Summary
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.
Eligibility Criteria
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):
- A) Any abnormal karyotype by metaphase analysis except for isolated t(11,14) and constitutional cytogenetic abnormality
- B) Fluorescence in situ hybridization (FISH) translocation 4;14
- C) FISH translocation 14;16
- D) FISH deletion 17p
- E) Beta2-microglobulin > 5.5 mg/L
- F) Cytogenetic hypodiploidy
- G) Plasmablastic morphology (>= 2%)
- 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)
- Matched HLA-A, B, C, DRB1, and DQB1 alleles by high resolution typing.
- Only a single allele disparity will be allowed for HLA-A, B, or C as defined by high resolution typing
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

- 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:
- Symptomatic coronary artery disease or ejection fraction 3 mg/dL; and symptomatic biliary disease;
- Karnofsky score = grade 2 peripheral neuropathy
- Patient has an active bacterial or fungal infection unresponsive to medical therapy
- DONOR: Identical twin
- DONOR: Donors unwilling to donate PBSC
- 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
