Cisplatin, Gemcitabine and Bevacizumab in Combination for Metastatic Transitional Cell Cancer

Bladder Cancer Clinical Trial

Official title: A Phase II Trial of Cisplatin, Gemcitabine and Bevacizumab in Combination for Metastatic Transitional Cell Cancer: Hoosier Oncology Group GU04-75

Status Completed

Clinical Trial Summary

Cisplatin is a very important agent for the treatment of TCC as it has a single agent response rate of approximately 15%. However, it has been most important as a part of combination chemotherapy, MVAC initially and now in combination with gemcitabine. Single agent gemcitabine has demonstrated an overall response rate (ORR) of approximately 25%, including some complete responses (CR), with minimal toxicity in patients with advanced bladder cancer. Bevacizumab, a murine anti-human VEGF monoclonal antibody, has been advanced for use in combination with cytotoxic chemotherapy to delay time to disease progression in patients with metastatic solid tumors.

This trial is designed to further assess the efficacy, safety and tolerability of this regimen in this patient population.

Clinical Trial Description

OUTLINE: This is a multi-center study.

• Cisplatin 70 mg/m2 Day 1

• Gemcitabine 1250 mg/m2 Day 1 and 8

• Bevacizumab 15 mg/kg Day 1

Review toxicity every cycle (every 3 weeks) Review for radiographic response every 2 cycles (every six weeks)

Progressive disease = off protocol therapy

Patients will be treated for up to a maximum of 8 cycles of cisplatin and gemcitabine (24 weeks of therapy). If a patient has not progressed by the end of 24 weeks (completion of cisplatin and gemcitabine), then patient will be treated with bevacizumab at 15 mg/kg every three weeks for a maximum of 12 months of bevacizumab therapy (since study entry).

If at any time patient has undue toxicity or progressive disease, patient will be removed from the study and followed until progression and for survival.

If the patient has Grade 3 or 4 neurotoxicity and/or the creatinine rises above 2.0, then the cisplatin will be discontinued and the patient continued on study and treated with gemcitabine and bevacizumab at the same dose and schedule.
