  Purpose

RATIONALE: Studying samples of tumor tissue and blood from patients with cancer in the laboratory may help doctors learn more about changes that may occur in DNA and identify biomarkers related to cancer. It may also help doctors predict a patient's response to treatment and help plan the best treatment.

PURPOSE: This phase II trial is studying gene expression in predicting treatment response in patients receiving gemcitabine and S-1 for locally advanced unresectable or metastatic pancreatic cancer.

Primary Outcome Measures:
  • • To correlate intratumoral expression level of ribonucleotide reductase subunit 1 (RRM1) with response to gemcitabine in patients with advanced pancreatic cancer. [ Time Frame: 2 years after the last patient is enrolled ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • To correlate intratumoral expression levels of other genes, including deoxycytidine kinase (dCK), equilibrative nucleoside transporter 1 (ENT1) and concentrative nucleoside transporters 1 and 3 (CNT1 and CNT3), with response to gemcitabine. [ Time Frame: 2 years after the last patient is enrolled ] [ Designated as safety issue: No ]
  • • To correlate intratumoral expression levels of thymidylate synthase (TS), thymidine phosphorylase (TP), dihydropyrimidine dehydrogenase (DPD), orotate phosphoribosyltransferase (ORPT) with response to the combination of gemcitabine/S-1. [ Time Frame: 2 years after the last patient is enrolled ] [ Designated as safety issue: No ]
  • • To estimate median survival using the therapeutic strategy outlined herein, entailing sequential addition of agents and decision-making based on early CA19-9 biomarker response. [ Time Frame: 2 years after the last patient is enrolled ] [ Designated as safety issue: No ]
  • To determine the safety of this approach. [ Time Frame: 8 weeks after 6th patient is enrolled ] [ Designated as safety issue: Yes ]
  • • To determine the percentage of patients classified as potential biomarker responders (during the initial gemcitabine monotherapy phase). [ Time Frame: 2 years afetr the last patient is enrolled ] [ Designated as safety issue: No ]
  • • To calculate the time to progression on each successive line of treatment. [ Time Frame: 2 years after the last patient is enrolled ] [ Designated as safety issue: No ]
  • • To calculate the proportion of patients with at least 25% decline in CA 19-9 biomarker (= "biomarker response") on each successive line of treatment. [ Time Frame: 2 years after the last patient is enrolled ] [ Designated as safety issue: No ]

Enrollment: 21
Study Start Date: January 2007
Study Completion Date: October 2010
Primary Completion Date: October 2010 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: S-1
    S-1 is given as follows: 25 mg/m2 bid on days 1-7 and 15-21 of the cycle (28 days)
    Drug: gemcitabine hydrochloride
    Patients will receive gemcitabine at a dose of 1,000 mg/m2 i.v. at a fixed-dose rate (FDR) infusion of 10 mg/m2/minute (100 minutes), once a week for 3 consecutive weeks, followed by one week rest. Each 4 week period is referred to as a treatment cycle

Criteria

Inclusion criteria

  • Adenocarcinoma of the pancreas that is already or will be histologically or cytologically proven.
  • Patients must have either locally advanced (unresectable) or metastatic disease.
  • Radiographically measurable disease is not required.
  • No prior therapy for advanced pancreatic cancer. Treatment given in the adjuvant setting (radiation and/or chemotherapy, given either concurrently or systemically) does not count as prior therapy as long as progressive disease occurs > 6 months following completion of treatment.
  • Greater than or equal to 18 years of age.
  • ECOG performance status of 0 or 1 (See Appendix D).
  • Laboratory criteria:
  • ANC > 1500/µL
  • Platelet count > 100,000/µL
  • Hemoglobin > 9 g/dL (may be transfused or receive epoetin alfa to maintain or exceed this level)
  • INR < 1.5 (except those subjects who are receiving full-dose warfarin
  • Total bilirubin < 2.0 mg/dL
  • AST or ALT < 5 times upper limit of normal for subjects with documented liver metastases; < 2.5 times the upper limit of normal for subjects without evidence of liver metastases
  • Serum creatinine < 2.0 mg/dL
  • Serum CA19-9 > 2X upper limits of normal.
  • All patients must be informed of the investigational nature of this study and must sign and give written informed consent in accordance with institutional and federal guidelines.
  • Women or men of reproductive potential must agree to use an effective contraceptive method during treatment and for 6 months afterwards.

Exclusion criteria

  • Inability to comply with study and/or follow-up procedures
  • Disease determined to be not amenable to biopsy upon review of radiographs by the oncologist and/or interventional radiologist.
  • Clearly resectable disease in a patient who is an appropriate operative candidate.
  • History of other disease, metabolic dysfunction, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a disease or condition that contraindicates the use of an investigational drug or that might affect the interpretation of the results of the study or render the subject at high risk from treatment complications
  • Prior systemic therapy for advanced pancreatic cancer
  • Pregnant (positive pregnancy test) or lactating
  • Use of anti-neoplastic or anti-tumor agents not part of the study therapy, including chemotherapy, radiation therapy, immunotherapy, and hormonal anticancer therapy, is not permitted while participating in this study.
  • Use of concurrent investigational agents is not permitted.

S-1 Specific Exclusion Criteria

  • Is receiving a concomitant treatment with drugs interacting with S-1. The following drugs are prohibited because there may be an interaction with S-1:
  • Sorivudine, brivudine, uracil, dipyridamole, cimetidine, and folinic acid (may enhance S-1 activity).
  • Allopurinol (may diminish S-1 activity).
  • Phenytoin (S-1 may enhance phenytoin activity).
  • Flucytosine, a fluorinated pyrimidine antifungal agent (may enhance S-1 and flucytosine activity).
  • Pilocarpine (may inhibit cytochrome P-450 enzyme 2A6 activity).
