  • Performance status ECOG 0-3
  • Acceptable organ function as defined by:
• Bilirubin <2 x upper limit of normal
• ALT and AST <2.5 x upper limit of normal
• Serum creatinine <3.0 mg/dL
• ANC ≥1.0 x 109/L

• Platelet count ≥50 x 109/L

  • Non-pregnant and non-lactating
  • Life expectancy of more than six months
  • Written informed consent in accordance with federal, local and institutional guidelines
  • Females of Child Bearing Potential* (FCBP) must have a negative serum or urine pregnancy test, with a sensitivity of at least 50 mIU/mL within 10-14 days and again within 24 hours prior to prescribing lenalidomide for cycle 1 (prescription must be filled with 7 days) and must either commit to continued abstinence from heterosexual intercourse or begin TWO methods of acceptable methods of birth control, one highly effective method AND one additional effective method of birth control (contraception) AT THE SAME TIME, at least 28 days before she starts taking lenalidomide. FCBP must also agree to ongoing pregnancy Testing. (See Appendix G: Risks of Fetal Exposure, Pregnancy Testing Guidelines and Acceptable Birth Control Methods) *A female of childbearing potential is a sexually mature female who: 1) has not undergone a hysterectomy or bilateral oophorectomy; or 2) has not been naturally postmenopausal for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months).

  • All study participants must be registered into the mandatory RevAssist® program and be willing and able to comply with the requirements of RevAssist®.
  • Subjects must adhere to the study visit schedule and other protocol requirements and receive outpatient treatment and laboratory monitoring at the institute that administers the drug.
  • Subjects must agree to take enteric-coated aspirin 81-325 mg orally daily, or if history of prior thrombotic disease or allergy to aspirin, must be fully anticoagulated with warfarin (INR 2-3), Pradaxa® or be treated with full-dose, low molecular weight heparin, as if to treat deep venous thrombosis (DVT)/pulmonary embolism.
