Study of Lenalidomide in Combination With RICE With Lenalidomide Maintenance Post-Auto Transplant for DLBCL

Inclusion Criteria

• •1. Age 18 years at the time of signing the informed consent form.
• •2. Able to adhere to the study visit schedule and other protocol requirements.
• •3. Histologically confirmed diffuse large B cell lymphoma
• •4. Relapsed or refractory after one prior therapeutic treatment for DLBCL. Refractory is defined as patients received adequate prior treatment and did not respond during treatment or progressed within 90 days of last treatment.
• •5. Measurable disease with at least on bidimensional lymph node or tumor mass \>1.5 cm in the longest diameter that can be followed for response as a target lesion as measured by PET or CT
• •6. Histologically confirmed involvement of the bone marrow by DLBCL on the bone marrow biopsy without other measurable disease
• •7. Eligible for autologous stem cell transplant
• •8. All previous cancer therapy, including radiation, hormonal therapy and surgery, must have been discontinued at least two weeks prior to treatment in this study.
• •9. Eastern Cooperative Oncology Group (ECOG) performance status of 2 at study entry (see Appendix B).
• •10. Laboratory test results within these ranges:
• •* Absolute neutrophil count \>1000 /mm³
• •* Platelet count \> 50,000/mm³ (unless bone marrow is heavily infiltrated with underlying disease (50% or more) Calculated creatinine clearance of ≥ 60 mL/min by Cockroft-Gault formula (Appendix E) for patients enrolled into the phase I portion of the study (Stage I). Calculated creatinine clearance of ≥ 30 mL/min by Cockroft-Gault formula for patients enrolled into the phase II portion of the study (Stage II). See Section 5.4.2 for lenalidomide dose adjustment for calculated creatinine clearance \> 30ml/min and \< 60ml/min.
• •* Total bilirubin \< 1.5 x Upper Limit of Normal (ULN).
• •* Aspartate Aminotransferase (SGOT) and Alanine Aminotransferase (SGPT) \< 3 x ULN.
• •11. Disease free of prior malignancies for \> 5 years with exception of currently treated basal cell, squamous cell carcinoma of the skin, or carcinoma "insitu" of the cervix or breast.
• •12. All study participants must be registered into the mandatory RevAssist® program, and be willing and able to comply with the requirements of RevAssist®.
• •13. Females of childbearing potential (FCBP)† must have a negative serum or urine pregnancy test with a sensitivity of at least 50 milli-International unit (mIU)/mL within 10 - 14 days prior to and again within 24 hours of starting lenalidomide 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 28 days before she starts taking lenalidomide. FCBP must also agree to ongoing pregnancy testing. Men must agree to use a latex condom during sexual contact with a FCBP even if they have had a successful vasectomy. All patients must be counseled at a minimum of every 28 days about pregnancy precautions and risks of fetal exposure. See Appendix A: Risks of Fetal Exposure, Pregnancy Testing Guidelines and Acceptable Birth Control Methods.
• •14. Able to take aspirin (81 or 325 mg) daily as prophylactic anticoagulation (patients intolerant to acetylsalicylic acid (ASA) may use warfarin or low molecular weight heparin).
• •\-
