Brief Summary:

Chemotherapy is often used to help shrink the cancer temporarily and may improve survival for patients with incurable pancreas cancer that has spread to other organs. In Canada, the gemcitabine chemotherapy is used to treat pancreas cancer that has spread. The combination of oxaliplatin with other chemotherapies, including 5-fluorouracil, leucovorin, and irinotecan has also been studied and has benefit for patients with advanced pancreas cancer. To date, there is no test that can be done on a patient's tumour to tell if chemotherapy will work in pancreatic cancer. Human equilibrative nucleoside transporter 1 (hENT1) has been shown to be a possible predictor that gemcitabine may or may not work but this needs to be proven in a randomized study where patients get treated with gemcitabine or a different kind of chemotherapy while their tumours get tested for hENT1.

This study is being done because we want to prove that hENT1 can predict if gemcitabine will work in advanced pancreas cancer and if it can, we also would like to show that a different chemotherapy combination called FOLFOX (a combination of 5-fluorouracil, leucovorin, and oxaliplatin) will be helpful for patients whose tumours don't have hENT1.

Drug: Gemcitabine
1000 mg/m2 IV weekly for 3 weeks then one week off

Cycles to be 2 weeks in length Oxaliplatin 100 mg/m2 IV day 1 Leucovorin 400 mg/m2 IV day 1 5-FUl 400 mg/m2 IV day 1 5-FU 2400 mg/m2 IV continuous infusion over 46 hours starting day 1
Drug: 5FU, leucovorin, oxaliplatin
Oxaliplatin 100 mg/m2 IV day 1 Leucovorin 400 mg/m2 IV day 1 5-FUl 400 mg/m2 IV day 1 5-FU 2400 mg/m2 IV continuous infusion over 46 hours starting day 1

Primary Outcome Measures :
  1. The difference Progression Free Survival (PFS) between Gemcitabine and FOLFOX treated patients in hENT1 high and hENT1 low pancreatic adenocarcinoma. [ Time Frame: 2 Years ]
    Progression free survival will be measured from the date of diagnosis to the date of progression or death, patients who did not progress or is alive at the last date of follow-up will be censored for the analysis. Kaplan-Meier method will be used to estimate the survival function and log-rank test will be utilized to compare the study arms. The median PFS and the corresponding 95% confidence interval will be used for reporting purpose. The hazard ratio and the corresponding 95% two-sided confidence interval using Cox-proportional hazard regression will be presented.

Secondary Outcome Measures :
  1. The difference in overall response rate (ORR) between the two treatment arms. [ Time Frame: 2 years ]
  2. The rate of disease control (DCR), defined as the sum of complete response rate (RR), partial RR, and stable disease between the two treatment arms. [ Time Frame: 2 Years ]
  3. The difference in overall survival (OS) between the two treatment arms. [ Time Frame: 2 Years ]
  4. Health-related quality of life (HRQL) parameters in patients with metastatic pancreas adenocarcinoma treated in both treatment arms. [ Time Frame: 2 Years ]

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Histologically documented metastatic pancreatic adenocarcinoma not previously treated with palliative systemic therapy
  • Metastatic disease based on the presence of clinically and/or radiologically documents Measurable disease base on RECIST.
  • Adequate tissue (core biopsy) available for IHC testing of hENT1. This may be from primary tumour or metastatic site. Fine needle aspiration biopsies will not be allowed. Histological/cytological confirmation of tissue to ensure sufficient material is available for hENT1 analysis by the Cross Cancer Institute is required prior to starting a patient on study. Biopsies from metastatic sites must be obtained ≥ 3 months after any adjuvant chemotherapy (if applicable). If a patient has had previous surgical resection of their primary tumours, that tissue can be utilized. Tissue sufficient for preparing ≥ 10 unstained slides for central storage and testing is required.
  • ECOG performance status of 0 - 1.
  • Age ≥ 18 years.
  • Life expectancy of at least 3 months based on discretion of treating oncologist.
  • Adequate hematologic function defined by the following laboratory parameters:
  • Hemoglobin ≥ 100
  • Platelet count ≥ 100
  • Absolute granulocyte count ≥ 1.5
  • Adequate hepatic and renal function defined by the following laboratory parameters:
  • AST and ALT ≤ 2.5 X upper limit of institutional normal (≤ 5 if liver metastases)
  • bilirubin ≤ upper limit of institutional normal
  • calculated creatinine clearance of ≥ 50 mL/min using the Cockcroft-Gault formula, if just below 50 mL/min based on this formula then GFR ≥ 50 mL/min as determined by 24 hr urine collection
  • Patients who have received prior chemotherapy or radiation delivered as part of initial curative therapy (i.e. neoadjuvant or adjuvant chemotherapy administered alone and/or concurrently delivered with radiation and/or surgery) are permitted as long as that treatment was completed at least 6 months prior to study start date.
  • Patients may have received prior palliative radiotherapy (unless radiation was curative therapy to pelvis or to ≥ 25% of bone marrow stores) if this radiation was ≥ 4 weeks before study entry and patients must have recovered from the toxic effects of this treatment
  • Patients may have received prior surgery if this surgery was ≥ 4 weeks before study entry and patients must have recovered from the toxic effects of this treatment.
  • Patients must have the ability to read, understand, and sign an informed consent and must be willing to comply with study treatment and follow-up.

Exclusion Criteria:

  • Patients who have received prior palliative chemotherapy for their metastatic pancreatic adenocarcinoma.
  • Radical pancreatic resections (e.g. Whipple procedure) are not allowed < 6 months prior to randomization. Exploratory laparotomy, palliative (e.g. bypass) surgery, or other procedures (e.g. stents) are not allowed < 14 days prior to randomization. In any of the above cases, patients must be adequately recovered and stable prior to randomization.
  • Prior treatment with > 6 cycles of traditional alkylating agent-based chemotherapy, > 2 cycles of carboplatin-based chemotherapy, prior treatment with irinotecan or oxaliplatin chemotherapy, or concurrent treatment with other experimental drugs or anti-cancer therapy.
