Lapatinib, Cisplatin, Gemcitabine as First-Line Therapy in Treating Patients With Locally Advanced or Metastatic Urothelial Cancer

• Status: Completed
• Trial end date: 2012-08-01
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Lapatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as cisplatin, and gemcitabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving lapatinib together with combination chemotherapy may kill more tumor cells.

PURPOSE: This phase I trial is studying the side effects and best dose of lapatinib when given together with cisplatin and gemcitabine as first-line therapy in treating patients with locally advanced or metastatic urothelial cancer.
