Measurable residual disease (MRD) is a major prognostic factor in newly diagnosed multiple myeloma. An assessment of an MRD-guided consolidation strategy in patients who are eligible for autologous stem-cell transplantation (ASCT) may be useful.
Methods: In this phase 3 trial, we randomly assigned transplantation-eligible patients with newly diagnosed myeloma who had completed induction therapy with isatuximab, carfilzomib, lenalidomide, and dexamethasone (Isa-KRd) to receive consolidation therapy according to their MRD status. Patients who were MRD-negative at 10-5 sensitivity (i.e., <1 cancer cell per 100,000 normal cells, as assessed by next-generation sequencing were assigned to undergo ASCT and receive Isa-KRd for two cycles (ASCT group) or to receive Isa-KRd for six cycles (Isa-KRd group). Patients who were MRD-positive at 10-5 sensitivity were assigned to undergo tandem ASCT (two ASCTs within a short period; tandem ASCT group) or to undergo ASCT and receive Isa-KRd for two cycles (single ASCT group). The primary end point was an MRD-negative status at 10-6 sensitivity before maintenance therapy.
