A Phase II Single-arm Study of AMG 386 in Combination With Docetaxel for Advanced Urothelial Carcinoma After Failure of a Platinum-containing Regimen

This study plans to learn more about the combination of AMG 386 and docetaxel for the
treatment of advanced urothelial cancer. Subjects are being asked to be in this research
study because they have advanced urothelial cancer which has progressed after treatment with
a platinum-based therapy.

The hypothesis is that AMG 386 will increase the historical response rate of docetaxel as a
single agent.

AMG 386 is a medication made to stop the growth of blood vessels in cancer tissues. Cancer
relies on new blood vessels to bring it oxygen and nutrients to grow. Docetaxel is
currently approved by the FDA for advanced urothelial, hormone-refractory prostate, breast,
non-small cell lung, gastric, and squamous cell carcinoma of the head and neck.

Inclusion Criteria:

1. Subjects must have a histologically confirmed urothelial carcinoma. At least 50% of
the tumor must demonstrate transitional cell histology.

2. Measurable disease as defined by Response Evaluation Criteria in Solid Tumors
(RECIST) 1.1 criteria

3. CT or MRI of the chest, abdomen, and pelvis, with or without contrast, within 28 days
of registration. A whole body bone scan may be performed at the discretion of the
treating physician.

4. Only if clinically indicated, a CT or MRI (MRI preferred) scan of the brain within 28
days of registration.

5. Progressive disease after a platinum-containing regimen (cisplatin or carboplatin) or
intolerance to platinum-based therapy for urothelial carcinoma. Subjects who
received adjuvant cisplatin or carboplatin-based chemotherapy for urothelial
carcinoma and currently have recurrent or progressive disease are eligible.

6. Men or women > 18 years old

7. Generally well-controlled blood pressure with systolic blood pressure ≤ 140 mmHg AND
diastolic blood pressure ≤ 90 mmHg prior to enrolment or randomization. The use of
anti-hypertensive medications to control hypertension is permitted

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

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

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.

4. History of arterial or venous thrombosis, including transient ischemic attack (TIA),
within 12 months prior to 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
