Viral Therapy in Treating Patients With Relapsed or Refractory Multiple Myeloma

A Phase 1 Study of Reolysin Alone in Patients With Relapsed or Refractory Multiple Myeloma

• Status: Completed
• Phase: Phase 1
• Study type: Interventional
• Enrollment: 12 (actual)
• Sponsor: National Cancer Institute (NCI) · NIH
• Sex: All
• Age: 18 Years
• Healthy volunteers: Not accepted

Summary

This pilot phase I trial studies the side effects and the best dose of giving viral therapy to patients with relapsed or refractory multiple myeloma. Viral therapy, such as wild-type reovirus, may be able to kill cancer cells without damaging normal cells.

Detailed description

PRIMARY OBJECTIVES: I. Determine safety and tolerability of Reolysin in patients with relapsed multiple myeloma. II. Obtain evidence of Reovirus replication by immunohistochemical co-localization of Reovirus and tubulin staining in marrow clot sections obtained on cycle 1 day 8. SECONDARY OBJECTIVES: I. Obtain preliminary data on response as determined by International Myeloma Working Group criteria after infusion of Reolysin as a single agent. (Clinical) II. Obtain pilot overall and progression free survival data for all treated patients. (Clinical) III. Assess neutralizing anti-reovirus assay (NARA) results on days 1, 8, 15, and once days 22-28 during cycle 1. (Correlative) IV. Assess feasibility of staining for RAF/MEK/ERK in CD138+ cells using marrow clot sections obtained from pre-treatment specimen. (Correlative) V. Cryopreserve PBMCs for future ancillary studies focused initially on lymphocyte subset(s) and myeloid derived suppressor cell changes after Reolysin infusion during cycle 1. (Correlative) VI. Cryopreserve CD138+-selected cells at screening and after treatment for future ancillary studies of genetic and epigenetic changes focused in part on endoplasmic reticulum (ER) stress. (Correlative) OUTLINE: This is a dose-escalation study. Patients receive wild-type reovirus IV over 60 minutes on days 1-5. Treatment repeats every 28 days for up to 12 courses in the absence of disease progression or unacceptable toxicity. Patients undergo bone marrow aspirate at baseline and periodically during study for RAF/MEK/ERK expression and wild-type reovirus replication analysis by immunohistochemistry. Blood and cryopreserved CD138+ selected cell samples are also collected for future ancillary studies. After completion of study treatment, patients are followed up for 4 weeks.
