• Life expectancy ≥ 12 months.
• Adequate organ function - Hepatic function, with serum Alanine Aminotransferase ≤ 2.5 times the upper limit of normal and serum direct bilirubin ≤ 2 mg/dL (34 µmol/L) within 21 days prior to initiation of therapy. Creatinine clearance (CrCl) ≥ 40 mL/minute within 21 days prior to start of therapy.

• All subjects must agree to comply with and be enrolled in Revlimid Risk Evaluation and Mitigation Strategy (REMS) program.
• Meet institutional criteria for autologous hematopoietic cell transplantation according to investigator's assessment.
• At least 30% ethnic/racial minorities will be included. If necessary, accrual will be held of non-ethnic minority patients while continuing for ethnic minorities in order to ensure at least 30% representation.
