The purpose of this study is to determine whether S-1 is effective in slowing tumor activity in patients with locally advanced or metastatic pancreatic cancer who have not had chemotherapy. The study is also looking at the safety of S-1.

1: Experimental
All patients will receive S-1 orally at a dose of 30 mg/m2 twice daily (BID) for 14 days followed by a 1-week recovery period, repeated every 3 weeks.

Drug: S-1
All patients will receive S-1 orally at a dose of 30 mg/m2 twice daily (BID) for 14 days followed by a 1-week recovery period, repeated every 3 weeks. The trial will proceed to the second stage only if sufficient efficacy is demonstrated in Stage 1.

Locally advanced or metastatic pancreatic cancer is relatively unresponsive to chemotherapy. This is true for the nucleoside analogue gemcitabine, with a response rate of approximately 10%, as well as for 5-fluorouracil (5-FU). Even when gemcitabine is combined with other chemotherapeutic drugs or biological agents, the overall tumor response rate remains basically unchanged. S-1 is a new generation oral fluoropyrimidine that combines Tegafur (5-fluoro-1-(tetrahydro-2-furanyl)-2,4(1H,3H)-pyrimidinedione [FT]), an oral prodrug of 5-FU, with two modulators, Gimeracil (5-chloro-2,4-dihydroxypyridine [CDHP]), which inhibits 5-FU degradation by dihydropyrimidine dehydrogenase (DPD) inhibition, and Oteracil potassium (Oxo), which inhibits 5-FU phosphorylation in the digestive tract. This combination of 3 compounds is designed to achieve enhanced antitumor activity while decreasing gastrointestinal toxicity.
Ages Eligible for Study: | 18 Years and older |
Genders Eligible for Study: | Both |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
1. Has provided written informed consent. 2. Has histologically or cytologically confirmed locally advanced, unresectable or metastatic adenocarcinoma of the pancreas not amenable to curative radiotherapy or surgery.
3. Has measurable disease as defined by Response Evaluation Criteria in Solid Tumors (RECIST) criteria (ie, lesions that can be accurately measured in at least one dimension with the longest diameter ≥ 20 mm using conventional techniques or ≥ 10 mm using spiral computed tomography [CT] scan).
4. Is able to take medications orally. 5. Is 18 years of age or older. 6. Has a Karnofsky Performance Status (KPS) ≥ 70% (see Appendix A). 7. Has a life expectancy of ≥ 12 weeks. 8. Has adequate organ function as defined by the following criteria:
Calculated creatinine clearance ≥ 60 mL/min (based on serum creatinine) (Cockcroft-Gault85 formula) 9. Is willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures.
Exclusion Criteria:
1. Has had treatment with any of the following within the specified time frame prior to study drug administration:
Current enrollment in another clinical study with an investigational agent. Patients participating in surveys or observational studies are eligible to participate in this study.
2. Major surgery within the previous 3 weeks. 3. Symptomatic brain metastasis not controlled by corticosteroids. 4. Leptomeningeal metastasis. 5. Previous or concurrent malignancy other than pancreatic cancer except adequately treated carcinoma in-situ of the cervix or non-melanoma skin cancer. 6. Uncontrolled ascites requiring drainage at least twice a week. 7. Other serious illness or medical condition(s) including, but not limited to, the following:
Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or study drug administration, or may interfere with the interpretation of study results, and in the judgment of the Investigator would make the patient inappropriate for entry into this study.
8. 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:
Flucytosine, a fluorinated pyrimidine antifungal agent (may enhance S-1 and flucytosine activity).
9. Is a pregnant or lactating female. 10. Has known sensitivity to 5-FU. 11. Is a patient with reproductive potential who refuses to use an adequate means of contraception (including male patients).
