Brief Summary:

The purpose of this study is to explore the combination of Elotuzumab in combination with autologous stem cell transplantation and lenalidomide maintenance to see what side effects it may have and how well it works for the treatment of symptomatic multiple myeloma diagnosed and treated with induction therapy in the past year.

Induction therapy is the first phase of treatment for multiple myeloma. The goal of induction therapy for multiple myeloma is to reduce the number of plasma cells in the bone marrow and the proteins that the plasma cells produce. Induction therapy is usually given for 3-4 weeks.

An autologous peripheral blood stem cell transplant is a procedure in which immature "stem cells" are collected and stored for future use. A high dose of chemotherapy is given to the patient to destroy myeloma cells, and the patient's stem cells are replaced.

The investigational drug in this program is elotuzumab. Elotuzumab is known as BMS-901608. Elotuzumab is a manufactured protein directed against a target found on multiple myeloma cells. Lenalidomide is currently approved for patients with multiple myeloma. Melphalan and cyclophosphamide, the drugs used during stem cell collection and transplant, are also approved by the U.S. FDA. Melphalan is an FDA-approved chemotherapy for multiple myeloma and is used as high-dose treatment prior to stem cell transplantation. Cyclophosphamide is an FDA-approved chemotherapy that may be used, either alone, or in combination with other drugs to treat multiple myeloma.


Condition or disease Intervention/treatment Phase
Multiple Myeloma Drug: Elotuzumab Drug: Lenalidomide Other: autologous PBMC reconstitution Other: ASCT Phase 1

Detailed Description:

This is a Phase 1b, open-label, trial investigating elotuzumab and autologous PBMC reconstitution with auto-SCT consolidation therapy and lenalidomide maintenance. Fifteen patients will be enrolled in this study.

This study is based on the hypothesis that the addition of Elotuzumab and autologous PBMC reconstitution to standard-of-care auto-SCT and lenalidomide maintenance will be safe and feasible. Furthermore, we hypothesize that Elotuzumab and PBMC reconstitution will target residual myeloma cells, enhance NK cell activation and ADCC, and promote tumor-specific humoral and cellular immune responses against myeloma cells, resulting in long-term maintenance of the minimal residual disease state.

Drug: Elotuzumab

The following must also be administered before any elotuzumab:

Dexamethasone 8 mg IV (on the day of elotuzumab infusion 45-90 mins prior to the start of infusion), the following 30 - 90 minutes prior to start of infusion: H1 blocker: diphenhydramine (25 - 50 mg po or IV) or equivalent, H2 blocker: ranitidine (50 mg IV) or equivalent (adjusted for renal failure as indicated), acetaminophen (650 - 1000 mg po).

Other: autologous PBMC reconstitution
Autologous peripheral blood mononuclear cell collection and reconstitution. PBMC will be collected from patients by standard apheresis procedures. Up to 25 ml of autologous plasma will also be recovered for dilution of cryopreserved products (if necessary). For reconstitution, Patients will be pre-medicated as per each institution's standard protocols prior to reinfusion of PBMC products. Patient ID will be checked and verified by nursing staff and the products will be re-infused by continuous intravenous infusion pump. Patient vital signs will be monitored every 15 minutes for the duration of the procedure as per standard reinfusion protocol.

Other: ASCT
Autologous peripheral blood stem cell transplantation. (stem cells from the patient's own marrow are "harvested," stored and then returned to the body (engrafted). To be done as part of standard of care.
Other Name: auto-SCT consolidation therapy
