The CASTOR Trial: DARZALEX®+ Vd After 1 Prior MM Therapy


DARZALEX® + Velcade® (bortezomib) + dexamethasone

A multicenter, open-label, active-controlled phase 3 study1,2

  • A majority (76%) of patients received prior treatment with an immunomodulatory agent
  • More than half (69%) of patients received prior treatment with a proteasome inhibitor (PI)1

Patients were refractory to prior therapies1,2*

  • 32% to the last line of treatment
  • 33% to an immunomodulatory agent only
    • 24% in the DARZALEX® + Vd arm and 33% in the Vd arm to lenalidomide
*Please note that this is not a full list of prior therapies reported at baseline and that bortezomib-refractory patients were excluded from the study.2
