Summary:

      The study is being done to compare the combination of lenalidomide and dexamethasone followed
      by autologous peripheral blood stem cell transplant (PBSCT) and lenalidomide and
      dexamethasone without PBSCT in patients with untreated multiple myeloma. This comparison will
      include how the subjects respond to each study treatment combination, and what side effects
      are caused by each combination.
