The purpose of this study is to evaluate conversion rate to minimal residual disease (MRD) negativity following the addition of daratumumab to lenalidomide relative to lenalidomide alone, when administered as maintenance treatment to anti-cluster of differentiation 38 (CD38) treatment naive participants with newly diagnosed multiple myeloma who are MRD positive as determined by next generation sequencing (NGS) at screening, following high-dose therapy (HDT) and autologous stem cell transplant (ASCT).
