PRIMARY outcome

Timeframe: 4 Months

Timeframe: 4 Months

PFS is defined as the time from D1 of treatment until progression or death as a result of any cause. Progressive Disease (PD), 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

SECONDARY outcome

Timeframe: 4 Months

Estimate response rate (RR) in patients with metastatic UC who have progressed after first-line chemotherapy. Response rate will be the number of patients with complete response and/or partial response. Response will be based on Response Evaluation Criteria in Solid Tumors (RECIST) 1.1. Radiographic response will be measured by RECIST, Response Evaluation Criteria In Solid Tumors Criteria, indicating if subject experienced a Complete Response (CR), disappearance of all target lesions; Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions; Stable Disease (SD), no response or less response than Partial or Progressive; or Progressive Disease (PD), 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.

SECONDARY outcome

Timeframe: 30 Days

Characterize the safety profile of palbociclib in patients with metastatic UC after first-line chemotherapy. The NCI Common Terminology Criteria for Adverse Events is a descriptive terminology which can be utilized for Adverse Event (AE) reporting. A grading (severity) scale is provided for each AE term. Grade 1 Mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated. Grade 2 Moderate; minimal, local or noninvasive intervention indicated; limiting age-appropriate instrumental Activities of Daily Living (ADL). Grade 3 Severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self care ADL. Grade 4 Life-threatening consequences; urgent intervention indicated. Grade 5 Death related to AE.
