Summary

RATIONALE: Lapatinib ditosylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether lapatinib ditosylate is more effective than a placebo in killing tumor cells. PURPOSE: This randomized phase II/III trial is studying how well lapatinib ditosylate works compared to a placebo in treating patients with stage IV bladder cancer.

Detailed description

OBJECTIVES: Primary * Compare progression-free survival in patients with HER1- and/or HER2-overexpressing stage IV bladder cancer who have been randomized to maintenance therapy with lapatinib ditosylate or placebo following first-line chemotherapy. Secondary * Compare overall survival between these patient groups. * Evaluate the safety and tolerability of the regimens in these patients. * Assess and compare quality of life between these patient groups. OUTLINE: This is a multicenter study. Patients are stratified according to ECOG performance status and response to first line chemotherapy (complete or partial response vs stable disease). Patients are randomized to 1 of 2 treatment arms. * Arm I: Patients receive oral lapatinib ditosylate once daily in the absence of disease progression or unacceptable toxicity. * Arm II: Patients receive oral placebo once daily in the absence of disease progression or unacceptable toxicity. Patients undergo quality of life assessment by EORTC QLQ-C30 at baseline and every 4 weeks during study treatment. After completion of study treatment, patients are followed up periodically for up to 5 years.
