This multicenter phase II trial will evaluate palbociclib (PD-0332991) in patients with metastatic urothelial carcinoma (UC) with cyclin-dependent kinase inhibitor 2A (CDKN2A) (also referred to as p16) loss and positive Retinoblastoma (Rb) expression after failure of first-line chemotherapy.

This multicenter phase II trial will evaluate palbociclib (PD-0332991) in patients with metastatic urothelial carcinoma (UC) with cyclin-dependent kinase inhibitor 2A (CDKN2A) (also referred to as p16) loss and positive Retinoblastoma (Rb) expression after failure of first-line chemotherapy. The study will enroll up to 40 patients to identify 36 evaluable patients, using a Simon's two-stage design, with a primary endpoint of progression free survival (PFS) at 4 months (PFS4). Secondary objectives include estimating median PFS, overall survival (OS), response rate (RR) and exploratory objectives include an evaluation of molecular predictors of response and resistance.

Phase II Trial of Palbociclib in Patients With Metastatic Urothelial Cancer After Failure of First-Line Chemotherapy

Phase II Trial of Palbociclib (PD-0332991) in Patients With Metastatic Urothelial Cancer (UC) After Failure of First-Line Chemotherapy

Estimate progression free survival (PFS) at 4 months in patients with metastatic urothelial cancer (UC) who have progressed after first-line chemotherapy. PFS is defined as the percent of patients who are alive and free from progression at 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

Overall survival is defined as the time from day 1 of treatment until death as a result of any cause.

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.

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.
