8. Adequate organ and hematological function as evidenced by the following laboratory studies:

   a. Hematological function, as follows: i. Absolute neutrophil count (ANC) ≥ 1.5 x 109/L ii. Platelet count ≥ 100 x 109/L iii. Hemoglobin ≥= 9 g/dL b. Hepatic function, as follows: i. Aspartate aminotransferase (AST) ≤ 2.5 x upper limit of normal (ULN), ii. Alanine aminotransferase (ALT) ≤ 2.5 x ULN iii. Alkaline phosphatase ≤ 2.0 x ULN iv. Total bilirubin within normal limits (WNL) c. Hemostatic function, as follows: i. International normalized ratio (INR) ≤ 1.5 ii. Activated Partial thromboplastin time (aPTT) ≤ 1.5 x ULN d. Renal function, as follows: i. Calculated creatinine clearance ≥ 40 cc/min according to the Cockcroft-Gault formula: Creatinine Clearance calculator (CrCl) (mL/min) = (140-age) x actual body weight (kg) (x 0.85 for females) 72 x serum creatinine (mg/dL) ii. Urinary protein quantitative value of ≤ 30 mg in urinalysis or ≤ 1+ on dipstick, unless quantitative protein is ≤ 1000 mg in a 24 hour urine sample e. Cardiac function, as follows (only in those with a known history of cardiac dysfunction or in those with symptoms indicative or cardiac dysfunction): i. Normal sinus rhythm or clinically stable arrhythmia well controlled on outpatient medication.

   ii. Left ventricular ejection fraction ≥ lower limit of normal (LLN) per institutional laboratory range, as determined by echocardiogram or multi gated acquisition scan (MUGA) scan within 28 days prior to enrollment. If no clear institutional standard, then the ejection fraction must be ≥ 50%.
9. All baseline laboratory results must be from within 14 days of registration
10. Competent to comprehend, sign, and date an institutional review board (IRB) - approved informed consent form
11. Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1 or 2.
12. Subject plans to begin protocol-directed therapy within 7 days of registration
13. All patients will be offered enrollment in the correlative biomarkers study

Exclusion Criteria:

1. Three or more previous systemic therapies or combination regimens for urothelial carcinoma (e.g. cisplatin given with gemcitabine is considered one regimen) in the recurrent or metastatic setting.
2. Grade 2 or greater neuropathy
3. Known history of central nervous system metastases. An MRI or CT scan of the brain will be performed within 28 days of study enrollment.

5. History of clinically significant bleeding within 6 months of study enrollment
6. Anticoagulation is allowed as long as the initiating thrombotic event was at least 12 months before enrollment. The use of aspirin and anti-platelet agents are also acceptable for any duration prior to enrollment. The concurrent use of low molecular weight heparin, heparinoids, or low dose warfarin (ie, 1 mg daily) for prophylaxis against thrombosis is acceptable while on study.
7. Subjects with pleural effusions or ascites.
8. Focal radiation therapy for palliation of pain from bony metastases within 21 days of study enrollment. Subjects who received radiation therapy must have recovered from all radiation induced toxicities prior to study enrollment
9. Currently or previously treated with AMG 386, or other molecules that inhibit the angiopoietins or Tie2 receptor including but not limited to, AZD-5180, XL-820, CEP 11981/SSR-106462, BSF-466,895, CGI-1842, LOC-590, XL-184, or CP- 8681596. (Previous treatment with bevacizumab is permitted.)
10. Current or previous treatment with docetaxel. (Previous treatment with paclitaxel is permitted.)
11. Treatment within 30 days prior to enrollment with strong immune modulators including but not limited to systemic cyclosporine, tacrolimus, sirolimus, mycophenolate mofetil, methotrexate, azathioprine, rapamycin, thalidomide, lenalidomide.
12. Clinically significant cardiovascular disease within 12 months prior to enrollment, including myocardial infarction, unstable angina, grade 2 or greater peripheral vascular disease, cerebrovascular accident, transient ischemic attack, congestive heart failure, or arrhythmias not controlled by outpatient medication
