Adding Daratumumab to Lenalidomide-Dexamethasone in MM

N Engl J Med; 2016 Oct 6; Dimopoulos, Oriol, et al

Adding daratumumab to lenalidomide and dexamethasone improved progression-free survival among patients with relapsed or refractory multiple myeloma, according to a phase 3 randomized trial involving 569 individuals.

Investigators randomly assigned participants—all of whom had multiple myeloma and had been given 1 or more previous lines of therapy—to receive lenalidomide and dexamethasone either alone (n=286) or combined with daratumumab (n=283). Among the results:

  • At a median follow-up of 13.5 months, disease progression or death occurred in ~2 in every 10 patients in the combination group, vs 4 in every 10 in the lenalidomide/dexamethasone-alone group.
  • Progression-free survival rate at 12 months was 83% in the combination group, vs 60% in the lenalidomide/dexamethasone-alone contingent.
  • Overall response was achieved in 93% of the combination group, vs ~three-fourths in the lenalidomide/dexamethasone-alone cohort.
  • Complete response rate or better was 43% and 19%, respectively.
  • Neutropenia occurred in ~half of patients in the combination group, vs 37% of those in the lenalidomide/dexamethasone-alone group.
