Preliminary Analysis of the MM21 Trial: Response Adaptive Salvage Treatment with Daratumumab-Lenalidomide-Dexamethasone (DRd) for Newly Diagnosed Transplant Eligible Multiple Myeloma Patients Failing Front-Line Bortezomib-Based Induction Therapy

Abstract

Bortezomib-based induction (V-IND) approaches are used in >90% of Australian newly diagnosed transplant eligible multiple myeloma (NDTE MM) patients (pts) with a maximum of 4 cycles of V-IND therapy available via the pharmaceutical benefits scheme (PBS) prior to a planned autologous stem cell transplantation (ASCT). However, NDTE MM patients failing V-IND (defined as best response < partial response [PR]) demonstrate shortened survival and continue to represent a sub-group of MM where a clear unmet medical need persists. The ALLG MM21 was designed to evaluate the efficacy of an early response adapted approach with a switch to an intensive Daratumumab-lenalidomide-dexamethasone (DRd)-based salvage-ASCT- consolidation strategy in patients failing V-IND.
