Inclusion criteria

1. Previous diagnosis of MM based on standard criteria as defined in Appendix A (Diagnostic Criteria for MM). Diagnostic studies need not be performed within 30 days of registration; 2. Patients must meet one of the disease criteria outlined in either a, b, or c: a. Patients with newly diagnosed high-risk MM achieving a partial response (PR) or better at the time of enrollment in response to systemic anti-myeloma therapy, which may include autologous hematopoietic stem cell transplant (HSCT). High risk is defined by the presence of any one of the following: i. High-risk chromosomal translocations by fluorescent in situ hybridization (FISH): t(4;14), t(14;16), t(14;20), del(17p), del(1p), amplification 1q ii. Myeloma Prognostic Risk Signature 70-Gene expression profiling (MyPRS GEP-70) high-risk signature either at diagnosis or at time of registration for the study iii. Lactate dehydrogenase (LDH) \> 300 U/L at diagnosis iv. Plasma cell leukemia v. Relapse from prior therapy within 12 months b. Patients with high-risk MM with at least 1 prior progression in PR or better in response to salvage systemic anti-myeloma therapy at the time of enrollment c. Patients with standard risk MM with 1 prior progression within 18 months from an autologous HSCT and in very good partial remission (VGPR) or better in response to salvage systemic anti-myeloma therapy at the time of enrollment. 3. Patients must have a suitable first-degree or second-degree related, Human leukocyte antigen (HLA)-haploidentical or HLA-matched stem cell donor. The donor and recipient must be identical at least one allele of each of the following genetic loci: HLA-A, HLA-B, HLA-Cw, major histocompatibility complex, class II, DR beta 1 (HLA-DRB1), and Major Histocompatibility Complex, Class II, DQ Beta 1 (HLA-DQB1). A minimum match of 5/10 is therefore required, and will be considered sufficient evidence that the donor and recipient share one HLA haplotype; 4. No previous AlloSCT (syngeneic HSCT permissible); 5. Any previous autologous HSCT must have occurred at least 3 months prior to start of conditioning; 6. Eastern Cooperative Oncology Group (ECOG) performance status of 0-2; 7. Life expectancy \> 6 months; 8. Adequate end organ function as measured by: 1. Left ventricular ejection fraction ≥ 35% or shortening fraction \> 25% 2. Bilirubin ≤ 3.0 mg/dL (unless due to Gilbert's syndrome or hemolysis), and alanine aminotransferase (ALT) and aspartate transaminase (AST) \< 5x upper limit of normal (ULN) 3. Forced expiratory volume at one second (FEV1) and forced vital capacity (FVC) \> 40% of predicted 9. Not pregnant or breast-feeding; 10. No uncontrolled infection. Note: Infection is permitted if there is evidence of response to medication; 11. The patient must be able to comprehend and have signed the informed consent.

Exclusion criteria

1. Diagnosis of any of the following cancers: 1. POEMS syndrome (plasma cell dyscrasia with polyneuropathy, organomegaly, endocrinopathy, monoclonal protein (M-protein) and skin changes) 2. Non-secretory myeloma (no measurable protein on Serum Free Lite Assay) 3. HTLV1 / HTLV2 positive 4. Diagnosis of amyloidosis 2. Failed to achieve at least a partial response (PR) to latest therapy; 3. Known history of HIV infection; 4. Systemic infection requiring treatment with antibiotics, antifungal, or antiviral agents within 7 days of registration; 5. History of malignancy other than MM within 5 years of registration, except adequately treated basal or squamous cell skin cancer; 6. History of serious allergy or reaction to any component of the MEDI-551 formulation that would prevent administration; 7. Active hepatitis B as defined by seropositivity for hepatitis B surface antigen or patients with positive hepatitis B core antibody titers. 8. Patients with hepatitis C antibody will be eligible provided that they do not have elevated liver transaminases or other evidence of active hepatitis.

Pre-assignment details

This study enrolled 1 participant, but the study was terminated before they could be assigned to the intervention, therefore, 0 participants started the study.

MEDI-551 Treatment Arm
Medi-551 maintenance therapy will be initiated on Day 60, Day 90, or Day 120 of NM-AlloSCT based on the eligibility criteria for the initiation of maintenance therapy as described in Section 3.1. MEDI-551 will be administered on 28-day cycles at a dose of 4mg/kg, as an IV infusion over 60 ±15 minutes. Infusion sets must contain a 0.2 micron in-line filter. MEDI-551 will be administered on days 1, 8, 15, and 22 of cycle 1, then 4mg/kg IV on day1 of cycles 2 through 12. Treatment may be stopped earlier if there is unacceptable toxicity, development of Grade 3 or 4 GVHD, documentation of disease progression, or patient withdrawal for other reasons.

Progression Free Survival

The progression free survival (PFS) of high-risk or relapsed multiple myeloma (MM) patients undergoing non-myeloablative bone marrow allogeneic transplantation (NM-AlloSCT) followed by maintenance therapy with MEDI-551.

Time frame: 5 years

Population: The study was terminated before any participant could start the study and receive intervention. Therefore, no data could be collected.
