Trial Description

Summary

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 cetuximab, can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. It is not yet known whether gemcitabine is more effective with or without cetuximab in treating pancreatic cancer.

PURPOSE: This randomized phase III trial is studying giving gemcitabine together with cetuximab to see how well it works compared to giving gemcitabine alone as first-line therapy in treating patients with locally advanced unresectable or metastatic adenocarcinoma of the pancreas.

Further Study Information

OBJECTIVES:

  • Compare the overall survival of patients with locally advanced unresectable or metastatic adenocarcinoma of the pancreas treated with gemcitabine and cetuximab vs gemcitabine alone.
  • Compare the time to treatment failure in patients treated with these regimens.
  • Estimate the percentage of patients with epidermal growth factor receptor (EGFR) tumor expression in patients treated with these regimens.
  • Compare the overall survival of patients in the EGFR-positive subset treated with these regimens.
  • Compare the toxicity of these regimens in these patients.
  • Compare the total response rate (confirmed and unconfirmed complete and partial response) in patients with measurable disease treated with these regimens.
  • Compare the patient report of pain and quality of life of patients treated with these regimens.

OUTLINE: This is an open-label, randomized, multicenter study. Patients are stratified according to disease status (locally advanced unresectable vs metastatic), Zubrod performance status (0 or 1 vs 2), and prior pancreatectomy (yes vs no). Patients are randomized to 1 of 2 treatment arms.

  • Arm I: Patients receive cetuximab IV over 1-2 hours on days 1, 8, 15, and 22 and gemcitabine IV over 30 minutes on days 1, 8, 15, and 22 for course 1 and days 1, 8, and 15 for all subsequent courses.
  • Arm II: Patients receive gemcitabine as in arm I. In both arms, courses repeat every 4 weeks in the absence of disease progression or unacceptable toxicity.

Quality of life is assessed at baseline, before each course, and at the end of study therapy.

Patients are followed every 6 months for 2 years and then annually for 1 year.

PROJECTED ACCRUAL: A total of 704 patients (352 per treatment arm) will be accrued for this study within 5 years.
