title: Novel therapies in myeloma.
abstract: OBJECTIVE
  Several novel therapies have been licensed for the treatment of myeloma in recent years. We summarize some of the trials leading to their approval and the current evidence for their clinical use. A number of promising agents undergoing phase I/II trial evaluation are also discussed.
  
  
  RESULTS
  The immunomodulatory drugs, thalidomide and lenalidomide, and the proteasome inhibitor, bortezomib, have been shown to be effective agents, both alone and as part of combination regimens, for the treatment of myeloma. Studies are now focusing on the optimal sequencing of these drugs throughout the disease course, with a view to maximizing antitumor efficacy and minimizing overlapping toxicities. New protocols are increasingly based on preclinical evidence of synergy. The incorporation of these agents into transplant-based treatment protocols has improved outcomes. Other examples of novel agents undergoing assessment at present include arsenic trioxide, hsp90 inhibitors and histone deacetylase inhibitors. Future developments are likely to include individualized treatment plans based on patient-specific parameters including cytogenetic analysis and gene expression profiling.
  
  
  CONCLUSIONS
  Thalidomide, lenalidomide and bortezomib can now be considered as standard options both as first-line agents and beyond for the treatment of myeloma, with respective combinations also emerging as valid choices for all stages of the disease.
