Continuous lenalidomide (LEN) therapy versus observation following nonimmunomodulatory compound-based induction therapy in newly diagnosed multiple myeloma (NDMM): MM-027 trial.

TPS8630 Background: Several recent trials have shown improvements in progression-free survival (PFS) with continuous LEN treatment (Tx) in NDMM patients (pts). PFS was 45%-59% higher using LEN therapy vs. control arm and rates of overall survival (OS) were consistently improved (Attal, NEJM 2012; Facon, ASH 2013, McCarthy, NEJM 2012; Palumbo, NEJM 2012, Palumbo ASCO 2013). Therefore an effective strategy of continuous Tx is of great importance to outcomes. Methods: This phase 3b, multicenter, randomized, open-label study will compare PFS of LEN single-agent vs. observation after non-immunomodulatory compound based induction therapy in NDMM pts (≥ 65 yrs) or 6 cycles of non-immuno...
