Each patient must meet all of the following inclusion criteria to begin IRD Consolidation:

• Between the ages of 18 and 70 years of age (inclusive) at time of enrollment
• Voluntary written consent must be given before performance of any study-related procedure not part of standard medical care, with the understanding that consent may be withdrawn by the patient at any time without prejudice to future medical care

• Women of childbearing potential must follow pregnancy testing requirements as outlined in the Revlimid REMS program material. This is defined as either committing to continued abstinence from heterosexual intercourse or beginning TWO acceptable methods of contraception (one highly effective method and one additional effective method AT THE SAME TIME) at least 28 days prior to the start of lenalidomide, for the duration of study participation, and for 28 days following the last dose of lenalidomide.
