Study Summary

This phase I/II trial studies the safety of the combination of bortezomib, dexamethasone, and pembrolizumab with or without pelareorep in treating patients with multiple myeloma that has come back (relapsed) or does not response to treatment (refractory). Chemotherapy drugs, such as bortezomib and dexamethasone, 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. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. A virus modified in the laboratory, such as pelareorep, may be able to kill cancer cells without damaging normal cells. Giving the combination of bortezomib, dexamethasone, and pembrolizumab with pelareorep may work better in treating patient with multiple myeloma.

Primary Outcome

Incidence of dose-limiting toxicities resulting from pelareorep (PELA) in combination with bortezomib-dexamethasone (BOR-D) and pembrolizumab will be assessed. Severity of Adverse Events (AEs) will be graded according to National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 5.0.
