Consolidation and maintenance therapy with lenalidomide, bortezomib and dexamethasone (RVD) in high-risk myeloma patients

Abstract

Prior studies have shown that myeloma patients exhibiting either genetically defined high-risk disease or plasma cell leukemia have a poor outcome with a median overall survival (OS) of ≤3 years. Results of IFM 2005-01 and 02 suggest that relatively limited bortezomib-containing induction regimens did not produce a major survival benefit among these patients. However, results of recent studies suggest that combination therapy may benefit these patients when given early and again later in the treatment. We evaluated a combination maintenance/consolidation regimen (RVD) following autologous stem cell transplant (ASCT) for high-risk patients to evaluate the impact of this approach on outcome. Following initiation of RVD maintenance, 51% of patients achieved stringent complete response (sCR), with 96% achieving at least VGPR as best response. Median progression free survival (PFS) for all patients is 32 months with a 3-year OS of 93%. The regimen was well tolerated with no grade 3/4 neuropathy. Early ASCT followed by RVD maintenance is a promising strategy for high-risk myeloma patients and delivered excellent response rates, and promising PFS and OS.
