Background: In younger, medically fit patients (pts) with newly diagnosed (ND) multiple myeloma (MM), autologous stem cell transplant (SCT) remains a standard of care. Prior to SCT, induction triplets with at least one of the newer compounds are recommended. Bortezomib (V), lenalidomide (R) and dexamethasone (D; VRD) ranks amongst the most effective treatments. VRD + SCT proved superior over VRD alone in a randomized, controlled trial (RCT). We found encouraging efficacy and low toxicity with RAD (RD and adriamycin) + SCT and decided to compare RAD versus VRD induction in an RCT. Methods: The DSMM XIV study was set up according to a double 2x2-factorial design to enroll NDMM pts up to 65 years (yrs). Post-induction (PI) CR rate was the efficacy endpoint for the initial study phase. We hypothesized CR rate with RAD would be non-inferior to an estimated 20% CR with VRD. The study was powered to confirm non-inferiority of RAD at a 10% margin with a one-sided α level of .05. Minimal residual disease (MRD) was analyzed by eight-color flow cytometry (EuroFlow standards) on marrow samples. Results: 476 pts were randomized between 05/2012 and 06/2016, 469 of whom (median age 55 (range, 32–65) yrs) received at least one dose of study drug. 18.3% of pts had ISS stage III MM and 17.2%, elevated LDH. 11.3% of pts had del17p; 11.1% had t(4;14); and 4% had t(14;16). 232 pts were randomized to 3 four-week RAD cycles and 237 to 3 three-week VRD cycles, respectively. 89.7% of RAD versus 93.2% of VRD pts completed all induction cycles. PI CR rate was 11.8% (90% CI, 7.9%-16.3%) with RAD versus 13.0% (90% CI, 8.9-18.0) with VRD, (P = .697). 72/317 pts (22.7%) with paired baseline/PI samples achieved negative MRD at a median sensitivity level of 6.73x10^-6. 47 (20.3%) RAD versus 35 (14.8%) VRD pts experienced treatment-emergent SAEs (P = .144). Treatment-related induction mortality was 0% in either arm. Conclusions: To the best of our knowledge, this is the first RCT to compare two lenalidomide-based triplets prior to SCT. The endpoint was met with comparable PI CR rates for RAD and VRD, respectively. Tolerability was encouraging in both arms. Follow-up data is needed to analyze time-dependent endpoints.
