  • Age ≥ 70 and ≤ 85 years.
  • ECOG performance status ≤2.
  • Subject must have serum monoclonal paraprotein (M-protein) level ≥0.5 g/dL or urine M-protein level ≥200 mg/24 hours, or serum immunoglobulin involved free light chain ≥10 mg/dL and abnormal serum immunoglobulin kappa lambda free light chain ratio.
  • LVEF ≥40% as determined by a MUGA scan or ECHO.
  • Adequate hepatic function characterized by the following:

oTotal bilirubin ≤1.5 x ULN. oAST ≤2.5 x ULN oALT ≤2.5 x ULN.

  • Estimated creatinine clearance ≥30 mL/min (according to the Cockcroft Gault formula, by 24-hour urine collection for creatinine clearance, or per the local institutional standard method).

  • Adequate BM function characterized by the following:

    • Absolute neutrophil count ≥1.0 × 109/L (use of granulocyte-colony stimulating factors is permitted if completed at least 7 days prior to planned start of dosing).
    • Platelet count ≥50 × 109/L (transfusion support is not permitted).
    • Hemoglobin ≥8 g/dL (transfusion support is permitted).
  • Non-vasectomized male patients agree to practice appropriate methods of birth control

Exclusion Criteria
  • Previous exposure to chemotherapy (i.e. melphalan, high-dose melphalan and/or cyclophosphamide) with the exception of patients who have received an autologous stem cell transplantion with a progression free survival of at least 36 month.

  • Plasma cell leukemia.

  • Systemic amyloid light chain amyloidosis.

  • POEMS Syndrome.
