Gemcitabine and Imatinib Mesylate as First-Line Therapy in Patients With Locally Adv. or Metastatic Pancreatic Cancer

• Status: Completed
• Trial end date: 2010-10-01
• Target enrollment: 0
• Participant gender: All

Summary

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

PURPOSE: This phase II trial is studying how well giving gemcitabine together with imatinib mesylate works as first-line therapy in treating patients with locally advanced or metastatic pancreatic cancer.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No
