Brief summary

We will combine an oral investigational vascular endothelial growth factor (VEGF inhibitor) called pazopanib which is being studied in kidney cancer will be combined with standard chemotherapy called taxol in patients with relapsed recurrent urothelial cancer.

Detailed description

Based on the results from the Phase 1 study of pazopanib combined with paclitaxel and the activity of paclitaxel in urothelial cancer, testing this regimen in a disease where there is an unmet need appears appropriate.

Inclusion criteria

First recurrence after treatment with a maximum of two chemotherapeutic regimens. 3. Subjects must provide written informed consent prior to performance of study-specific procedures or assessments, and must be willing to comply with treatment and follow up. Procedures conducted as part of the subject's routine clinical management (eg, blood count, imaging study) and obtained prior to signing of informed consent may be utilized for screening or baseline purposes provided these procedures are conducted as specified in the protocol. 4. Age ≥ 18 years 5. Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1 6. Measurable disease criteria by RECIST criteria 7. Adequate organ system function as defined below 1.

Design outcomes

Primary

MeasureTime frameDescription
Objective Tumor ResponseEvery 8 weeksThe tumor response rate was assessed per the Response Evaluation Criteria In Solid Tumors (RECIST). RECIST criteria are a set of published rules that define when cancer patients improve (respond); stay the same (stable); or worsen (progression) during treatments. RECIST criteria offer a simplified and conservative extraction of imaging data suitable for wide application in clinical trials. The criteria presume that linear measures are an adequate substitute for 2-dimensional (2D) methods and includes 4 response categories: * Complete response (CR) = Disappearance of all target lesions * Partial response (PR) = 30% decrease in the sum of the longest diameter of target lesions * Progressive disease (PD) = 20% increase in the sum of the longest diameter of target lesions * Stable disease (SD) = Small changes that do not meet above criteria Objective tumor response means those with response better than stable disease, ie, complete response (CR) + partial response (PR).

The Bellmunt prognostic risk factor score is a tool that is often used to predict treatment outcomes before initiating a secondline treatment regimen. The risk factors used to calculate the Bellmunt score include: * Eastern Cooperative Oncology Group (ECOG) performance status less than or equal to 1 * Presence of liver metastases * Presence of visceral involvement (defined as liver, lung, bone or any non-lymph node) * Lymph node-only involvement * Hemoglobin concentration \< 10 g/dL The score is calculated based on the presence of 0; 1; 2; or 3 of the above prognostic factors. This outcome reports median overall survival based on whether the participant had 0; 1; 2; or 3 prognostic factors.
