Wild-Type Reovirus, Bortezomib, and Dexamethasone in Treating Patients With Relapsed or Refractory Multiple Myeloma

Recurrent Plasma Cell Myeloma Clinical Trial

Official title: A Phase 1b Study of REOLYSIN® (Reovirus Serotype 3 - Dearing Strain) Combined With Standard Doses of Bortezomib and Dexamethasone in Patients With Relapsed/Refractory Multiple Myeloma

Status Completed

Clinical Trial Summary

This phase Ib trial studies the safety and best dose of wild-type reovirus in combination with bortezomib and dexamethasone and to see how well they work in treating patients with multiple myeloma that has returned (relapsed) or does not respond to treatment (refractory). A virus, called wild-type reovirus, may be able to infect cancer cells and slow the cancer growth and kill cancer cells. Bortezomib and dexamethasone may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving wild-type reovirus together with bortezomib and dexamethasone may be a better treatment for multiple myeloma.

Clinical Trial Description

PRIMARY OBJECTIVES:

I. To determine the maximum tolerated dose (MTD) with the maximum REOLYSIN (wild-type reovirus) dose limited to 4.5 x 10^10 tissue culture infection dose (TCID)50 and the safety profile of REOLYSIN in combination with bortezomib and dexamethasone in patients with relapsed or refractory multiple myeloma (MM). (Phase 1b) II. To further explore the safety and tolerability of the combination and to determine the overall response rate (ORR) (complete response [CR] + partial response [PR]) to REOLYSIN in combination with bortezomib and dexamethasone in patients with relapsed or refractory MM. (Phase 1b Dose Expansion)

SECONDARY OBJECTIVES:

I. To determine ORR in the Phase 1b part to the combination at escalating doses.

II. To determine the progression-free survival (PFS) of patients with relapsed or refractory MM treated with REOLYSIN in combination with bortezomib and dexamethasone.

III. To evaluate the effect of REOLYSIN in combination with bortezomib and dexamethasone treatments on overall survival (OS).

IV. To conduct pharmacodynamic studies as described.

OUTLINE: This is a phase Ib, dose-escalation study of wild-type reovirus followed by a phase Ib expansion trial.

Patients receive dexamethasone orally (PO), intravenously (IV), or intramuscularly (IM) and bortezomib subcutaneously (SC) (preferably) or IV over 3-5 seconds on days 1, 8, and 15. Patients also receive wild-type reovirus IV over 60 minutes on days 1, 2, 8, 9, 15, and 16. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 1 month and then every 3 months thereafter. ;
