Hemoglobin > 8 g/dL
Adequate renal function: Calculated creatinine clearance ≥ 30ml/min by Cockcroft-Gault formula
Low risk myeloma is defined as the absence of the following adverse features[21]: t(4;14) by FISH or metaphase cytogenetics; t(14,16) or t(14;20) by FISH or metaphase cytogenetics; Deletion 17q13 by FISH; Deletion 13 by metaphase analysis; Aneuploidy by metaphase analysis; Î’2 microglobulin > 5.5.

Females of childbearing potential (FCBP) must have a negative serum or urine pregnancy test with a sensitivity of at least 50 milli-international units per milliliter (mIU/mL) within 10 14 days prior to and again within 24 hours of prescribing lenalidomide (prescriptions must be filled within 7 days) and must either commit to continued abstinence from heterosexual intercourse or begin TWO acceptable methods of birth control, one highly effective method and one additional effective method AT THE SAME TIME, at least 4 weeks before taking lenalidomide. FCBP must also agree to ongoing pregnancy testing. Men must agree to use a latex condom during sexual contact with a female of child bearing potential even if they have had a successful vasectomy.

Exclusion Criteria:

Uncontrolled medical problems such as diabetes mellitus, congestive heart failure, coronary artery disease, hypertension, unstable angina, arrhythmias), pulmonary, hepatic and renal diseases unless renal insufficiency is felt to be secondary to multiple myeloma.
Any serious medical condition, laboratory abnormality, or psychiatric illness that would prevent the subject from signing the informed consent form
