Vaccine Therapy With or Without Cyclophosphamide in Treating Patients With Recurrent or Refractory Multiple Myeloma

Mayo Clinic48 enrolled

Overview

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.

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.

Outcomes

Primary Outcomes

Number of Phase I Participants With Dose-Limiting Toxicity Events (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 number of patients reporting a dose-limiting event are reported.

Time frame: 6 weeks

Maximum Tolerated Dose (MTD) (Phase I)

Time frame: 6 weeks

Proportion of Confirmed Response, Defined as a Partial Response (PR) or Better (Phase II)

Confirmed response will be evaluated using all cycles. The proportion of successes will be estimated by the number of successes divided by the total number of evaluable patients. Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR

Time frame: Up to 1 year

Time frame: At 1 year

Progression-free Survival (Phase II)

2-year progression-free survival (PFS2). Evidence of local recurrence, distant metastasis, or death from any cause within 2 years counted as events in the time-to-event Kaplan-Meier analysis of progression-free survival.

Time frame: At 2 years

Progression-free Survival (Phase II)

Progression free survival (PFS) is defined as the time from the date of randomization to the date of disease progression or death resulting from any cause, whichever comes first. Progression is defined according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. The median and 95% confidence intervals are estimated using the Kaplan-Meier estimator. Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions

Time frame: Up to 5 years
