A Randomized Phase III Trial Of Gemcitabine Plus Bevacizumab (NSC#704865 IND#7621) Versus Gemcitabine Plus Placebo In Patients With Advanced Pancreatic Cancer

new search

Trial Conditions
  • Pancreatic Cancer
What is the purpose of this trial?

RATIONALE: Drugs used in chemotherapy, such as gemcitabine, work in different ways to stop tumor cells from dividing so they stop growing or die. Monoclonal antibodies such as bevacizumab can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Bevacizumab may also stop the growth of tumor cells by stopping blood flow to the tumor. Combining gemcitabine with bevacizumab may kill more tumor cells. It is not yet known whether gemcitabine is more effective with or without bevacizumab in treating pancreatic cancer. PURPOSE: This randomized phase III trial is studying gemcitabine and bevacizumab to see how well they work compared to gemcitabine alone in treating patients with locally advanced or metastatic pancreatic cancer.
