Terminated due to inadequate rate of accrual.

This study will test the feasibility of combining 3 drugs, Revlimid with Doxil and Bevacizumab,and gather preliminary data on the potential activity of the combination in patients with platinum resistant/refractory ovarian cancer.

The combination of Doxil with Avastin has several aspects of interest to ovarian cancer treatment: 1) independent single-agent activity, 2) enhanced localization of Doxil is possible tumoral interstitial pressure via increased half-life (if liposomal egress is diminished) and decreased [42], 3) improved Doxil distribution, and 4) likely favorable toxicity profile since Doxil's only common problematic toxicity is to the skin (palmar-plantar erythrodysesthesia or PPE). Lenalidomide has also antiangiogenic properties, with a different mechanism of action than Avastin. Given the preliminary results of the effect of the combination of Doxil with Avastin, showing an increase in progression-free survival, we are interested in using a new thalidomide analog to maximize the angiogenic inhibition. This study will test the feasibility of combining all 3 drugs, and gather preliminary data on the potential activity of the combination in patients with platinum resistant/refractory ovarian cancer.

Inclusion Criteria:

• EOC patients must be platinum resistant/refractory (see 1.1 for definition) and be considered by the attending physician capable of being treated in this study according to GCP.
• Measurable disease by RECIST criteria or evaluable disease by GCIC criteria
• No prior anthracycline or lenalidomide use, unless the dose received was equal or less than one cycle and the patient did not progress on treatment.
• Subjects must have calculated creatinine clearance > 60ml/min by Cockcroft-Gault formula during the escalation phase.
• Subjects must have calculated creatinine clearance ≥ 30ml/min by Cockcroft-Gault formula during the expansion phase. See section below, "Dosing Regimen", regarding lenalidomide dose adjustment for calculated creatinine clearance > 30ml/min and < 60ml/min.
• Understand and voluntarily sign an informed consent form.
• All study participants must be registered into the mandatory RevAssist® program, and be willing and able to comply with the requirements of RevAssist®.
• Females of childbearing potential (FCBP)† must have a negative serum or urine pregnancy test with a sensitivity of at least 50 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.
• No contraindication to anticoagulation

Exclusion Criteria:

• Pregnant or breast feeding females. (Lactating females must agree not to breast feed while taking lenalidomide).
• Concurrent use of other anti-cancer agents or treatments.
• Known seropositive for or active viral infection with human immunodeficiency virus (HIV), hepatitis B virus (HBV) or hepatitis C virus (HCV). Patients who are seropositive because of hepatitis B virus vaccine are eligible.
• History of thromboembolic event within the last 3 months
• Known hypersensitivity to any component of Avastin
