Isatuximab Combination Therapy Achieves Superior MRD Negativity Rates in Newly Diagnosed Multiple Myeloma
- The isatuximab-carfilzomib-lenalidomide-dexamethasone (Isa-KRd) combination significantly improved minimal residual disease (MRD) negativity rates compared to standard KRd therapy in newly diagnosed multiple myeloma patients.
- In the phase 3 IsKia trial, Isa-KRd achieved 77% MRD negativity at 10-5 cutoff versus 67% with KRd alone, with even greater differences at the more stringent 10-6 cutoff (67% vs 48%).
- High-risk multiple myeloma patients showed particularly strong responses, with the GMMG-CONCEPT trial demonstrating 67.7% MRD negativity in transplant-eligible patients and sustained negativity for at least one year in 62.6% of cases.
- The treatment benefits were observed across all patient subgroups, including those with very high-risk cytogenetic features, while maintaining manageable safety profiles.
