“…Its use in induction and consolidation has been widely documented in studies, that evaluated the results of bortezomib, thalidomide and dexamethasone (VTD) with or without daratumumab showed an increase in Minimal Residual Disease negativity of 64% vs 44%in patients who received the quadruplet , this increase translated into a 53% decrease in the risk of progression or death as well as in PFS, with a follow-up of 44.5 months the median PFS had not been reached in the Daratumumab -VTD arm while in the VTD arm was 51.5 months, [7]. the impact was also demonstrated in other study that compared Bortezomib-Lenalidomide-Dexametasone (VRd) versus daratumumab plus VRd, the quadruplet achieve negative MRD in 51% of patients compared to 20.4% in patients in the VRd arm directly impacting PFS al 24 months (95.8 vs 89.8%) [8].…”
