Résumé
Date de début de l'étude : 1 mars 2004
Date à laquelle le premier participant a commencé l'étude.OBJECTIVES: Primary * Determine the maximum tolerated dose (MTD) of safingol when administered with cisplatin in patients with locally advanced or metastatic solid tumors. Secondary * Determine the toxic effects of this regimen in these patients. * Determine the clinical pharmacokinetics of this regimen in these patients. * Determine, preliminarily, the therapeutic activity of this regimen in these patients. * Determine a safe dose (i.e., near the MTD) for phase II evaluation of this regimen in these patients. * Determine, preliminarily, the role of ceramide and S1P, relative to response and apoptosis, in patients treated with this regimen. OUTLINE: This is an open-label, non-randomized, dose-escalation study of safingol. Patients receive safingol IV over 1 hour and cisplatin IV over 1 hour on day 1. Courses repeat every 21 days\* in the absence of disease progression or unacceptable toxicity. NOTE: \*Patients receive safingol on days 1 and 8 and cisplatin on day 8 for course 1 only; course 1 is 28 days in duration. Cohorts of 3-6 patients receive escalating doses of safingol until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. Once the MTD is determined, 10 additional patients are treated at that dose level.
