Summary
Brief summary (as posted)
This phase I trial is studying the side effects and best dose of 3-AP when given together with radiation therapy in treating patients with stage III pancreatic cancer that cannot be removed by surgery. 3-AP may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Radiation therapy uses high-energy x-rays to kill tumor cells. 3-AP may make tumor cells more sensitive to radiation therapy. Giving 3-AP together with radiation therapy may kill more tumor cells.

- type
- EXPERIMENTAL
- label
- Treatment (triapine, radiation therapy)
- description
- Patients undergo radiotherapy once daily, 5 days a week, for approximately 5.5 weeks (a total of 28 fractions). Patients also receive 3-AP (Triapine) IV over 2 hours 3 days a week every other week for 5.5 weeks. Treatment continues in the absence of disease progression or unacceptable toxicity. Cohorts of 3-6 patients receive escalating doses of 3-AP (Triapine) until the maximum tolerated dose (MTD) is determined.

- Drug: Triapine
Primary outcomes (1)
- measure
- MTD as assessed by the number of patients with dose-limiting toxicity (DLT)
- timeFrame
- Observed clinically for 3-4 hours after each 3-AP infusion during the first week of treatment
- description
- MTD will be the dose at which 1 or fewer patients (less than or equal to 1/6) experiences a DLT during the treatment cycle with the next higher dose having at least 2/3 or 2/6 patients experiencing DLT. DLT will be defined as greater than or equal to Grade 3 non-hematologic or greater than or equal to Grade 4 hematologic adverse event with the following exceptions: greater than or equal to Grade 3 nausea and greater than or equal to Grade 3 vomiting that improves with antiemetic therapy greater than or equal to Grade 3 diarrhea that improves with Lomotil.
