  1. D-Rd daratumumab plus lenalidomide/dexamethasone, Rd lenalidomide/dexamethasone, FISH fluorescence in situ hybridization.
  2. *Based on FISH/karyotyping.
  3. Patients with high cytogenetic risk had a t(4;14), t(14;16), or del17p abnormality.
  4. Safety population.
  5. §Based on reason, “patient refused to further study treatment” at “end of treatment.”
