Elranatamab is a bispecific antibody: binding of elranatamab to CD3-expressing T-cells and BCMA-expressing multiple myeloma cells causes targeted T-cell-mediated cytotoxicity. The main purpose of the study is to evaluate if the combination of Elranatamab, Daratumumab and Lenalidomide offers superior clinical benefit compared with the combination of Daratumumab, Lenalidomide and Dexamethasone in people with multiple myeloma.
There are 2 parts to this study. Part 1 will characterize the safety and tolerability of elranatamab when administered in combination with daratumumab and lenalidomide and will identify the optimal dose(s) of the combination regimen. Part 2 of the study will evaluate the minimal residual disease (MRD) negativity rate and the progression free survival (PFS) of the combination of elranatamab, daratumumab, and lenalidomide compared with the combination of daratumumab, lenalidomide, and dexamethasone in participants with newly diagnosed transplant-ineligible multiple myeloma.
