I. Determine the response rate in patients with recurrent, locoregionally advanced, or metastatic transitional cell carcinoma of the urothelium treated with VEGF Trap.
II. Determine the time to progression in patients treated with this drug. III. Determine overall survival of patients treated with this drug. IV. Determine the tolerability and safety of this drug in these patients.
OUTLINE: This is a multicenter study.
Patients receive VEGF Trap IV over 1 hour on day 1. Treatment repeats every 14 days in the absence of disease progression or unacceptable toxicity.
Patients undergo blood collection periodically during study for pharmacokinetic/pharmacodynamic correlative studies.
After completion of study treatment, patients are followed periodically.

|Official Title:||A Phase II Study of VEGF Trap (NSC 724770) in Patients With Recurrent or Metastatic Transitional Carcinoma of the Urothelium|
|Study Start Date :||November 2006|
|Actual Primary Completion Date :||April 2010|
|Actual Study Completion Date :||April 2014|
Experimental: Treatment (ziv-aflibercept)
Patients receive 4 mg/kg VEGF Trap IV over 1 hour on day 1. Treatment repeats every 14 days in the absence of disease progression or unacceptable toxicity.
Other: pharmacological study
- Tumor Response Rate [ Time Frame: From the start of the treatment until disease progression or recurrence, assessed up to 4 years ]
Response rate (RR) and progression free survival (PFS) were assessed in a 2-stage accrual design (22+18). A maximum of 40 patients were to be accrued to rule out a null hypothesized RR of 4% and PFS of 3 months versus alternative of 15% RR and 5.4 months PFS (corresponding to 4 month PFS of 40% vs 60%) with α=0.12 and β=0.19. If no more than 1 objective response (no more than 4.5%), and no more than 10 instances of 4-month PFS (no more than 45%), were observed among the initial 22 patients, the study would be terminated early and declared negative. Tumor response was evaluated by CT or MRI using RECIST v1.0 criteria.
Responders were confirmed partial or complete responses to treatment.
- Progression-free Survival (PFS) [ Time Frame: From start of treatment to time of progression, assessed up to 4 months ]Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions PFS using the product-limit method of Kaplan and Meier.
