Comparison of Elranatamab and Lenalidomide Versus Daratumumab and Lenalidomide as Post-transplant Maintenance Therapy in Patients With Newly Diagnosed Myeloma (ElMMA)

Summary

Lenalidomide is a standard of care for maintenance therapy after autologous stem cell transplantation in newly diagnosed myeloma patients. Recently, two large phase 3 randomized trials demonstrated a progression free survival benefit with daratumumab maintenance post autologous stem cell transplantation. Bispecific antibodies targeting B-Cell Maturation Antigen are approved for the treatment of relapsed refractory myeloma patients after 3 prior lines of therapy including proteasome inhibitor, immunomodulator IMiD and anti CD38 monoclonal antibody. In the cohort A of the MAGNETISMM-3 phase 2 study (n=123), elranatamab single-agent demonstrated strong efficacy with favorable safety profile in patients with advanced multiple myeloma (median of 5 prior lines, 96% of patients with triple class refractory disease). Lenalidomide has been shown to promote cytotoxic activity of CD3 bispecific antibodies. 7We propose a phase 2 randomized study comparing elranatamab plus lenalidomide versus daratumumab plus lenalidomide for 2 years as post-transplant maintenance in patients with newly diagnosed multiple myeloma. The primary objective is minimal residual disease rate after one year of maintenance. Secondary objectives include Progression-Free Survival, safety, quality of life, return to work and overall survival.
