Isatuximab, Iberdomide, Bortezomib, Dexamethasone in Transplant Ineligible/Deferred Newly Diagnosed Myeloma

This is an open-label, Phase 1b/2, multicenter study which will enroll patients with newly diagnosed multiple myeloma (NDMM), who are transplant ineligible or deferred, to induction followed by maintenance therapy. Participants will be registered in HCC CTMS OnCore before receiving any study-specific treatment, and study treatment is expected to begin within 5 days after registration. The study drugs used in this research include bortezomib, dexamethasone, isatuximab, and iberdomide (CC-220). The U.S. Food and Drug Administration (FDA) has approved bortezomib and dexamethasone for the initial treatment of multiple myeloma. The FDA has approved isatuximab for initial treatment of multiple myeloma in transplant ineligible patients and for myeloma that has returned after prior treatment. The FDA has not approved iberdomide (CC-220) for the treatment of multiple myeloma. The combination of these drugs, used as induction and maintenance therapy in this study, is considered investigational. The research study procedures include: screening for eligibility, in-clinic visits, urine tests, questionnaires, PET scans, blood tests, electrocardiograms (ECGs), bone marrow aspiration and biopsy, biobanking, and pregnancy tests for participants who are able to become pregnant. It is expected that about 88 people will take part in this study. Participants are classified and assigned treatment for induction based on baseline age 70 years status and myeloma frailty score and further assigned for maintenance based on baseline International Myeloma Working Group (IMWG)/International Myeloma Society (IMS) genomic risk classification.
