Daratumumab (DARA) (HuMax-CD38), a human IgG1? monoclonal antibody effectively mediates destruction of CD38-expressing malignant plasma cells. In the first-in-human dose-escalation study, 42% of heavily pretreated patients with relapsed or relapsed, refractory (RR) multiple myeloma (MM) treated with DARA alone (?4mg/kg) achieved partial response (PR) and 25% had minimal response (MR) (modified IMWG guidelines). In preclinical studies, DARA + lenalidomide (LEN) enhanced killing of MM cells in vitro.We evaluated safety, pharmacokinetics (PK) and efficacy of DARA + LEN + dexamethasone (DEX) in patients with relapsed or RR MM.
