Опис
OBJECTIVES:
Primary
- To determine the maximum tolerated dose of high-selenium Brassica juncea (BJ-Se) and capecitabine when administered in combination with irinotecan hydrochloride in patients with advanced malignancies.
- To determine the effects of BJ-Se on the pharmacokinetics of irinotecan hydrochloride and capecitabine.
Secondary
- To determine the effect of BJ-Se on the serum selenium and protein profile.
- To correlate response and tolerance to this regimen with expression of key enzymes involved as targets or with the metabolism of the components of treatment, including thymidylate synthase and dihydropyrimidine dehydrogenase.
- To evaluate changes to potential selenium related parameters.
OUTLINE: This is a multicenter, dose-escalation study of high-selenium Brassica juncea (BJ-Se) and capecitabine. The dose of capecitabine is escalated first, followed by dose escalation of BJ-Se.
Patients receive oral BJ-Se on days -7 to 21 in course 1 and on days 1-21 in all other courses. Patients also receive irinotecan IV on days 1 and 8 and oral capecitabine twice daily on days 1-14. Treatment repeats every 21 days in the absence of unacceptable toxicity or disease progression.
After the maximum tolerated dose (MTD) of capecitabine and BJ-Se are determined, additional patients are accrued and receive treatment at the MTD. Blood is collected from these patients during course 1 for pharmacokinetic studies.
