Phase 2 AMG 386 in Comb. Paclitaxel for Subjects With Advanced Recurrent Epithelial Ovarian or Primary Peritoneal Cancer

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
