Gemcitabine With or Without Erlotinib in Treating Patients With Unresectable Locally Advanced or Metastatic Pancreatic Cancer

Basic Trial Information

Phase	Type	Status	Age	Sponsor	Protocol IDs
Phase III	Treatment	Closed	18 and over	Pharmaceutical / Industry	CAN-NCIC-PA3 OSI-CAN-NCIC-PA3, NCT00026338, PA3

Objectives

1. Compare the overall survival rate in patients with unresectable locally advanced or metastatic pancreatic cancer treated with gemcitabine with or without erlotinib.
2. Compare the progression-free survival rate in patients treated with these regimens.
3. Compare the quality of life of patients treated with these regimens.
4. Compare the response rate and response duration in patients treated with these regimens.
5. Compare the nature, severity, and frequency of toxic effects of these regimens in these patients.
6. Correlate the expression of tissue epidermal growth factor receptor levels at diagnosis with outcome and response in patients treated with these regimens.
7. Determine the pharmacokinetics of erlotinib in these patients.

Entry Criteria

Disease Characteristics:

Endocrine therapy:

• Not specified

Radiotherapy:

• See Chemotherapy

  • Uncontrolled diarrhea that results in weight loss and vitamin deficiency

    OR

  • Requires IV hyperalimentation

• No significant ophthalmologic abnormalities, including the following:
  • Severe dry eye syndrome
  • Sjogren's syndrome
  • Keratoconjunctivitis sicca
  • Severe exposure keratopathy
  • Disorders that would increase the risk for epithelium-related complications (e.g., bullous keratopathy, aniridia, severe chemical burns, or neutrophilic keratitis)

Other:

• Not pregnant or nursing
• Negative pregnancy test
• Fertile patients must use effective contraception
• HIV negative
• No serious active infection

• No other prior malignancy within the past 5 years except cancer in situ or basal cell or squamous cell skin cancer

Expected Enrollment

A total of 800 patients (400 per treatment arm) will be accrued for this study within 11 months.

Outline

This is a randomized, double-blind, placebo-controlled, multicenter study. Patients are stratified according to participating center, extent of disease (locally advanced vs metastatic), and ECOG performance status (0-1 vs 2). Patients are randomized to one of two treatment arms.

• Arm I: Patients receive gemcitabine IV over 30 minutes on days 1, 8, 15, 22, 29, 36, and 43 of course 1 only, which lasts 8 weeks, and on days 1, 8, and 15 of all subsequent courses, which last 4 weeks each. Patients also receive 1 of 2 doses of oral erlotinib once daily.



• Arm II: Patients receive gemcitabine as in arm I and 1 of 2 doses of oral placebo once daily.

Treatment continues in both arms in the absence of disease progression or unacceptable toxicity.

Quality of life is assessed at baseline, on day 29 of course 1, on day 1 of all subsequent courses, at 4 weeks after study, and then every 12 weeks until disease progression.

Patients are followed at 4 weeks and then every 12 weeks thereafter.
