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.

Maximum Tolerated Dose (MTD) (Phase I)

The Maximum Tolerated Dose (MTD) is defined as the dose level below the lowest dose that induces dose-limiting toxicity (DLT) in at least one-third of patients graded according to NCI Common Terminology Criteria for Adverse Events (CTCAE) version 3.0. Dose-limiting toxicities include non-hematologic events graded 3 or higher and deemed at least possibly related to treatment. A total of 6 patients treated at the MTD will be sufficient to identify common toxicities at the MTD. The MTD is reported below.

Time frame: 6 weeks

Population: Only phase I stage 1 patients who completed the study are included in this analysis. Dose levels 1-6 of Phase I Stage 1 patients were combined in this analysis to determine the MTD as defined above.

Biodistribution and Kinetics of Virus Spread

Will be correlated with tumor distribution. Descriptive statistics and scatterplots will form the basis of presentation of these variables. Correlations between the laboratory values and other outcome measures will be carried out by standard parametric and non-parametric tests (e.g. Pearson's and Spearman's rho).

Time frame: Up to 6 weeks

NIS Gene Expression in Vivo

Will be correlated with tumor distribution. Descriptive statistics and scatterplots will form the basis of presentation of these variables. Correlations between the laboratory values and other outcome measures will be carried out by standard parametric and non-parametric tests (e.g. Pearson's and Spearman's rho).

Time frame: Up to 6 weeks

Other Pre-specified

Radiation Dose

The radiation dose that could be delivered to the bone marrow as well as critical organs such as the liver, lungs and kidneys if iodine-131 were to be administered using MIRDOSE 3 program will be estimated. Where patterns of correlation are indicated, ordinary and partial correlation coefficients (controlling for dose levels) will be calculated. Inferential testing for significant shifts in the correlative laboratory data results across dose levels will be carried out only as a hypothesis generating exercise.

Time frame: Up to 6 weeks

Other Pre-specified

Time Until Any Treatment Related Toxicity (Phase I)

Tolerability will be explored in an ancillary manner through time-related variables, including time until any treatment related toxicity. Simple summary statistics will be supplemented with Kaplan-Meier survival estimates and related confidence intervals. The effect of dose and ancillary dichotomized covariates such as age will be explored using log-rank testing involving one covariate at a time.

Time frame: Up to 1 year

Other Pre-specified

Time Until Hematologic Nadirs (White Blood Cells, ANC, Platelets) (Phase I)

Tolerability will be explored in an ancillary manner through time-related variables, including time until hematologic nadirs. Simple summary statistics will be supplemented with Kaplan-Meier survival estimates and related confidence intervals. The effect of dose and ancillary dichotomized covariates such as age will be explored using log-rank testing involving one covariate at a time.

Time frame: Up to 1 year

Other Pre-specified

Time Until Treatment Related Grade 3+ Toxicity (Phase I)

Tolerability will be explored in an ancillary manner through time-related variables, including time until treatment related grade 3+ toxicity. Simple summary statistics will be supplemented with Kaplan-Meier survival estimates and related confidence intervals. The effect of dose and ancillary dichotomized covariates such as age will be explored using log-rank testing involving one covariate at a time.

Time frame: Up to 1 year

Other Pre-specified

Viral Replication

Descriptive statistics and scatterplots will form the basis of presentation of these variables. Correlations between the laboratory values and other outcome measures will be carried out by standard parametric and non-parametric tests (e.g. Pearson's and Spearman's rho).

Time frame: Up to 6 weeks

Other Pre-specified

Viral Shedding

Descriptive statistics and scatterplots will form the basis of presentation of these variables. Correlations between the laboratory values and other outcome measures will be carried out by standard parametric and non-parametric tests (e.g. Pearson's and Spearman's rho).
