Brief summary: This phase I/II trial studies the side effects and best dose of vaccine therapy when given with or without cyclophosphamide and to see how well they work in treating patients with multiple myeloma that has come back (recurrent) or has not responded to previous treatment (refractory). Vaccines made from a gene-modified virus may help the body build an effective immune response to kill cancer cells. Drugs used in chemotherapy, such as cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving vaccine therapy together with cyclophosphamide may be a better treatment for multiple myeloma.

Detailed description: PRIMARY OBJECTIVES:

I. To determine the maximum tolerated dose (MTD) of oncolytic measles virus encoding thyroidal sodium iodide symporter (MV-NIS) when administered with or without cyclophosphamide in patients with relapsed or refractory multiple myeloma. (Phase I) II. To evaluate the confirmed response rate of MV-NIS alone in patients with relapsed or refractory multiple myeloma who have exhausted all therapeutic options. (Phase II, Cohort A) III. To evaluate the confirmed response rate of MV-NIS alone in patients who are relapsing from very good partial response (VGPR) or complete response (CR) and have not received myeloma directed therapy for at least 12 weeks. (Phase II, Cohort B)

SECONDARY OBJECTIVES:

I. To determine the safety and toxicity of the intravenous administration of an Edmonston vaccine strain measles virus engineered to express the thyroidal sodium iodide symporter (MV-NIS) when administered with or without cyclophosphamide in patients with relapsed or refractory multiple myeloma. (Phase I) II. To evaluate the confirmed response rate of MV-NIS in patients with relapsed or refractory multiple myeloma. (Phase I) III. To further evaluate the adverse event profile of MV-NIS in patients with relapsed or refractory multiple myeloma. (Phase II) IV. To evaluate overall survival, failure-free survival and progression-free survival. (Phase II)

TERTIARY OBJECTIVES:

I. To determine the time course of viral gene expression and virus elimination, and the biodistribution of virally infected cells at various times points after infection with MV-NIS (when administered with or without cyclophosphamide) using 99m-technetium (Tc) gamma camera imaging. (Phase I and II) II. To assess virus replication, viremia, viral shedding in urine and respiratory secretions, and virus persistence after systemic administration of MV-NIS (when administered with or without cyclophosphamide). (Phase I and II) III. To monitor humoral responses to the injected virus. (Phase I and II) IV. To explore the anti-myeloma efficacy (i.e. clinical response rate, time to progression, progression free survival, duration of response) of the virus using standard myeloma response criteria as well as immunoglobulin free light chain measurements. (Phase I and II)

OUTLINE: This is a phase I, dose-escalation study of MV-NIS followed by a phase II study. Patients are assigned to 1 of 2 treatment arms (Stage 1 or Stage 2) in phase I and assigned to Stage 1 in phase II.

STAGE 1 (MV-NIS ALONE, closed to accrual on 12/17/2009 and reopened 10/13/2011): Patients receive MV-NIS intravenously (IV) over 1 hour on day 1.

STAGE 2 (MV-NIS AND CYCLOPHOSPHAMIDE, temporarily closed to accrual on 10/13/11): Patients receive cyclophosphamide IV over 30 minutes and then MV-NIS IV over 1 hour 2 days later.

After completion of study treatment, patients are followed up at 6 weeks, 12 weeks, and then every 3 months for 1 year.
