Objectives: Daratumumab, a CD38-targeting human IgGκ monoclonal antibody, is approved as
monotherapy and in combination with standard-of-care regimens for the treatment of newly
diagnosed multiple myeloma (NDMM) and relapsed/refractory MM. Treatment with daratumumab
plus lenalidomide (R)/bortezomib (V)/dexamethasone (d) (D-RVd) in phase 2 GRIFFIN (NCT02874742)
significantly improved rates of stringent complete response (sCR) by end of post-transplant
consolidation therapy in patients with transplant-eligible NDMM vs RVd alone. Updated efficacy and
safety results following 12-month maintenance with R or daratumumab+R (D-R) are presented.
Methods: Patients with NDMM eligible for high-dose therapy and autologous stem cell transplant
(ASCT) were randomly assigned (1:1) to receive daratumumab±RVd induction (4 cycles), high-dose
therapy, ASCT, consolidation (2 cycles), and maintenance with daratumumab±R (24 months). During
