Curative Strategy (GEM-CESAR) for High-Risk Smoldering Myeloma (SMM): Carfilzomib, Lenalidomide and Dexamethasone (KRd) As Induction Followed By HDT-ASCT, Consolidation with Krd and Maintenance with Rd
Introduction: SMM is an asymptomatic and heterogeneous plasma cell disorder. Both Spanish Myeloma and ECOG Groups have demonstrated that pts at high risk of progression to active MM benefit from early treatment with R-based regimens. Our next step was to design this phase 2, single arm trial, focusing on the same population, but with the potential goal of cure, defined by sustained minimal residual disease negativity (MRD-ve) at 5 years after HDT-ASCT.
Conclusions: The primary end point of the trial was met, and 56% of the pts who completed induction and HDT-ASCT achieved MRD-ve. This “curative strategy for high risk SMM” continues being encouraging and 93% of pts remain alive and progression-free at 30 months and 98% of pts alive.
