  • Patient has been previously diagnosed with MM based on standard International Myeloma Working Group (IMWG) criteria and currently requires treatment.
  • Patient must have received at least one previous line of therapy for multiple myeloma including bortezomib
  • Patient must have demonstrated disease progression on or within 60 days of completion of the last therapy. Patient has measurable disease defined as at least one of the following:
  • Serum M protein ≥ 0.5 g/dL (≥5 g/L)
  • Urine M protein ≥200 mg/24 hours
  • Serum free light chain (FLC) assay: Involved FLC assay ≥10 mg/dL (≥100 mg/L) and an abnormal serum FLC ratio (<0.26 or >1.65)
  • Eastern Cooperative Oncology Group (ECOG) performance status ≤2
  • Negative serum or urine pregnancy test for women of child-bearing potential
  • Screening Laboratory parameters:
  • Absolute neutrophil count (ANC) ≥ 1,500 cells/dL (1.5 x 10^9/L). Granulocyte colony-stimulating factor (GCSF) is not permitted during screening to meet eligibility criteria and within 14 days of initiation of therapy
  • Platelet count ≥ 70,000 cells/dL (70 x 10^9/L) Platelet transfusion is not permitted during screening to meet eligibility criteria and within 14 days of initiation of therapy
  • Hemoglobin ≥ 8.0 g/dl ( red blood cell (RBC) transfusions are permitted during the screening period)
  • Total Bilirubin ≤ 1.5 X upper limit of normal (ULN) ; Aspartate transaminase (AST, or SGOT) and alanine transaminase (ALT, or SGPT) ≤ 2.5x ULN Estimated creatinine clearance by Cockcroft-Gault formula ≥ 50 mL/min

Exclusion criteria

  • Diagnosed or treated for another malignancy within 3 years prior to enrollment, with the exception of complete resection of basal cell carcinoma or squamous cell carcinoma of the skin, an in situ malignancy, or low risk prostate cancer after curative therapy.
  • Received any investigational drug within 14 days or 5 half-lives of the investigational drug, whichever is longer.
  • Prior anti-cancer therapy within 14 days.
  • Patient has any Grade 3 or > unresolved peripheral neuropathy from previous treatment.
  • Patient is human immunodeficiency virus (HIV) positive,.
  • Patient is Hepatitis B Surface antigen-positive or HBV-DNA copies > 10^3/ml
  • Patient has active hepatitis C infection.
  • Hypersensitivity to any of the required concomitant drugs or supportive treatments, including hypersensitivity to antiviral drugs
  • Known history of allergy to 2 or > drugs or any component of regimen
  • Any clinically significant, uncontrolled medical conditions that, in the treating Investigator's opinion, would impose excessive risk to the patient or may interfere with compliance or interpretation of the study results. Uncontrolled intercurrent illness may include, but is not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, clinically significant cardiac arrhythmia, or psychiatric illness/social situations as determined by treating investigator that would limit compliance with study requirements.
