Gemcitabine Hydrochloride With or Without Bevacizumab in Treating Patients Who Are Undergoing Surgery for Pancreatic Cancer
Phase II Randomized Study of Surgical Resection and Adjuvant Gemcitabine Hydrochloride With Versus Without Bevacizumab in Patients With Adenocarcinoma of the Pancreas

RATIONALE: Drugs used in chemotherapy, such as gemcitabine hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells an help kill them or carry tumor-killing substances to them. Bevacizumab may also stop the growth of pancreatic cancer by blocking blood flow to the tumor. Giving gemcitabine hydrochloride together with bevacizumab after surgery may kill any remaining tumor cells.

PURPOSE: This phase II trial is studying gemcitabine hydrochloride and bevacizumab to see how well they work compared to gemcitabine hydrochloride alone in treating patients who are undergoing surgery for pancreatic cancer.

OBJECTIVES:

Primary

  • Compare the disease-free interval in patients with adenocarcinoma of the pancreas treated with surgical resection followed by adjuvant gemcitabine hydrochloride with vs without bevacizumab.

Secondary

  • Compare overall survival in patients treated with these regimens.
  • Evaluate tumor gene expression profiles and levels of tumor angiogenesis markers to establish prognostic indicators for response in patients treated with these regimens.

OUTLINE: This is a randomized, controlled study.

All patients undergo surgical resection for the pancreatic tumor. Within 4-8 weeks after surgery, patients are stratified according to projected 2-year survival (≤ 5% vs > 5% and ≤ 33% vs > 33%). Patients are randomized to 1 of 2 treatment arms.

  • Arm I: Patients receive gemcitabine hydrochloride IV over 100 minutes on days 1, 8, and 15, and bevacizumab IV over 30-90 minutes on days 1 and 15. Treatment repeats every 28 days for 6 courses. Patients then receive bevacizumab IV alone every 2 weeks for up to 2 years in the absence of disease progression or unacceptable toxicity.
  • Arm II: Patients receive gemcitabine hydrochloride IV over 100 minutes on days 1, 8, and 15. Treatment repeats every 28 days for 6 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed periodically.

PROJECTED ACCRUAL: A total of 130 patients will be accrued for this study.
