Improving MRD Negativity Rates in Newly Diagnosed Multiple Myeloma Patients: a Response-adaptive Approach of Consolidation With One or Two Bispecific T-cell Engagers Against GPRC5D or BCMA

Summary

Multiple myeloma is characterized by a pattern of recurrent relapse and remains an incurable malignancy. Participants with minimal residual disease (MRD) after front line therapy with induction with or without transplant have worse prognosis than those with MRD negative disease. Bispecific T-cell-based immunotherapies have the potential to promote further reduction of malignant plasma cells thus improving rates of MRD negativity and improve patient outcomes. In this study, participants who are MRD positive after front line therapy will receive consolidation with GPRC5D-targeted bispecific talquetamab. We will test MRD negative conversion and if MRD negativity was not achieved, the participant will switch to a different target using the B-cell maturation antigen TCE, teclistamab. Consolidation will be continued for up to 1 year in participants who have achieved MRD negativity.
