Summary
This study is a phase 2, randomized, double-blind, placebo controlled, multi-center study to estimate the improvement in PFS (compared to control subjects) and evaluate the safety and tolerability of AMG 386 in combination with paclitaxel in the treatment of subjects with advanced recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer. Primary Outcome Measure: • Progression free survival (PFS) Secondary Outcome Measures: * Object Response Rate (ORR), duration of response (DOR). CA-125 response rate * Safety and Tolerability * Change and duration of change on blood levels of CA-125

In. Criteria -Subjects must have histologically or cytologically documented epithelial ovarian (FIGO Stage II-IV), fallopian tube or primary peritoneal cancer. (Subjects with pseudomyxoma or mesothelioma are excluded) * Radiographically documented progression per RECIST criteria with modifications or progression of CA-125 as defined by the Rustin during or subsequent to the last chemotherapy regimen. * May include measurable or non-measurable disease * All scans and x-rays used to document measurable or non-measurable disease must be done within 3 weeks (21 days) of enrollment. * No more than 3 previous regimens of anti-cancer therapy. Subjects must have received at least one platinum containing regimen * Female 18 years of age or older at the time the written informed consent is obtained * Subjects of child-bearing potential who have not undergone a bilateral salpingo-oophorectomy and are sexually active must use an accepted and effective non-hormonal method of contraception (ie, double barrier method (eg, condom plus diaphragm)) from signing the informed consent through 6 months after last dose of study drug. Laboratory * Adequate organ and hematological function as evidenced by the following laboratory studies within 2 weeks (14 days) of randomization: * Hematological function, as follows: Absolute neutrophil count (ANC) ≥ 1.5 x 109/L Platelet count ≥ 100 x 109/L and ≤ 850 x 109/L Hemoglobin ≥ 9 g/dL PTT or aPTT≤ 1.5 x ULN per institutional laboratory rand and INR ≤ 1.5 x 109/L per instiutiona laboratory range Renal function, as follows: Creatinine ≤ 2.0 mg/dL Calculated creatinine clearance \> 40 cc/min according to the Cockcroft-Gault formula -Hepatic function, as follows: Total bilirubin ≤ 2.0 x ULN SGOT (AST) and SGPT (ALT) ≤ 2.5 x ULN (≤ 5 x ULN if liver metastases are present) Nutritional * Albumin ≥ 2.8 mg/dL General * GOG Performance Status of 0 or 1 * Subject plans to begin protocol directed therapy within 7 days of randomization Ex Criteria * Subjects believed to be a higher than average risk for bowel perforation. This includes symptoms of partial or complete bowel obstruction, recent (within 6 months) history of fistula or bowel perforation, subjects requiring total parenteral nutrition and continuous hydration * Known ongoing small bowel dysfunction (ie, persistent nausea, vomiting) * Radiotherapy ≤ 14 days prior to randomization. Subjects must have recovered from all radiotherapy-related toxicities * If all sites of disease have been irradiated, documented progression must have occurred in at least one site of disease subsequent to the radiation therapy. * Previous abdominal radiotherapy * Has not yet completed a 21 day washout period for any previous anti-cancer systemic therapies (60 days for bevacizumab or any molecule of long half-life). * Enrolled in or has not yet completed at least 30 days since ending other investigational device or drug study(s), or is receiving other investigational agent(s) * Current or prior history of central nervous system metastasis * Common Terminology Criteria for Adverse Events (CTCAE) Version 3.0 peripheral neuropathy ≥grade 2 * History of arterial or venous thrombosis within 12 months prior to randomization * Concurrent or prior (within 1 week before study day 1) anticoagulation therapy, excluding aspirin and anti platelet agents. The concurrent use of low molecular weight heparin or low dose warfarin (ie, ≤ 1 mg daily) for prophylaxis against thrombosis is acceptable while on study * History of bleeding diathesis or clinically significant bleeding within 14 days of randomization * Major surgical procedure within 4 weeks (28 days) prior to Study Day 1 * Minor surgical procedure, or placement of central venous access device, within 7 days of Study Day 1 * Paracentesis and/or thoracentesis are permitted prior to and while on study at the discretion of the investigator as clinically indicated. Investigators should document the frequency of paracenteses and/or thoracentesis that occurred prior to the enrollment of the subject in this study on the appropriate eCRFs. Investigators should also document each paracentesis and/or thoracentesis that occurs while a subject is on study on the appropriate eCRFs. * Subjects with a history of prior malignancy, except: * Malignancy treated with curative intent and with no known active disease present for ≥ 3 years before enrollment and felt to be at low risk for recurrence by treating physician * Adequately treated non melanomatous skin cancer or lentigo maligna without evidence of disease * Adequately treated cervical carcinoma in situ without evidence of disease * Prior myeloablative high dose chemotherapy with allogeneic or autologous stem cell (or bone marrow) transplant * Clinically significant cardiac disease within 12 months of study enrollment, including myocardial infarction, unstable angina, grade 2 or greater peripheral vascular disease, congestive heart failure, or arrhythmias not controlled by outpatient medication, percutaneous transluminal coronary angioplasty/stent * Non-healing wound, ulcer or fracture * Ongoing or active infection * Unacceptable hypersensitivity to paclitaxel or drugs containing cremophor * Known positive test for human immunodeficiency virus (HIV), hepatitis C, or hepatitis B surface antigen * Currently or previously treated with angiopoietin inhibitors, or inhibitors of TIE-1 or TIE-2 including, but not limited to, AMG 386, XL880, XL820 * Prior therapy against vascular endothelial growth factor or the vascular endothelial growth factor receptors including, but not limited to, bevacizumab, sunitinib, sorafenib, motesanib (AMG 706) or cediranib (AZD-2171), is permitted so long as the agent does not have any known activity against angiopoietin 1 or 2, or the receptors TIE-1 or TIE-2 * Current or within 30 days of randomization treatment with immune modulators such as cyclosporine and tacrolimus
