Purpose:

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Calcitriol may increase the effectiveness of paclitaxel by making tumor cells more sensitive to the drug. PURPOSE: Phase I trial to study the effectiveness of combining calcitriol with paclitaxel in treating patients who have advanced solid tumors.


Study summary:

OBJECTIVES: - Determine the toxic effects and maximum tolerated dose of calcitriol when combined with paclitaxel in patients with advanced solid tumors. - Determine the effect of administration of calcitriol on the pharmacokinetics of paclitaxel in these patients. - Determine the effect of administration of paclitaxel on the pharmacokinetics of calcitriol in these patients. OUTLINE: This is a dose-escalation study of calcitriol. During course 1, patients receive oral calcitriol daily on days 1-3 of weeks 1-6 and paclitaxel IV over 1 hour on day 1 of week 1 and day 3 of weeks 2-6. During course 2 and subsequent courses, patients receive oral calcitriol daily on days 1-3 and paclitaxel IV over 1 hour on day 3 of weeks 1-6. Treatment continues every 8 weeks in the absence of disease progression or unacceptable toxicity. Cohorts of 3-6 patients receive escalating doses of calcitriol until the maximum tolerated dose (MTD) is determined. The MTD is defined as the highest dose giving an estimated probability of dose-limiting toxicity of no more than 0.30. PROJECTED ACCRUAL: A total of 60 patients will be accrued for this study.
