Bortezomib and Pembrolizumab With or Without Pelareorep for the Treatment of Relapsed or Refractory Multiple Myeloma, AMBUSH Trial (NCT05514990)

A Phase 1b/2 Study of Standard Doses of Bortezomib and Pembrolizumab ยฑ Reovirus (Pelareorep) Combination Therapy in Patients With Relapsed Multiple Myeloma (AMBUSH Study)

๐Ÿ”ต Active, Not Recruiting Phase1 / Phase2 ๐Ÿ’Š Investigational Drug / Biologic Sponsor: University of Southern California

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

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.
