Resumen
Fecha de inicio: 1 de julio de 1998
Fecha en la que se inscribió al primer participante.OBJECTIVES: I. Determine the safety and tolerability of motexafin gadolinium in combination with radiotherapy in patients with newly diagnosed glioblastoma multiforme. II. Determine the intratumoral pharmacology and quantitative pharmacokinetics of this drug in this patient population. OUTLINE: This is a multicenter, dose-escalation study of motexafin gadolinium. Patients receive a loading dose regimen comprising motexafin gadolinium IV over 10-15 minutes on days 1-5 or days 1-5 and 8-12 (cohort 7). After the loading dose regimen, patients receive a maintenance regimen comprising motexafin gadolinium IV 3 times weekly for a maximum of 6.5 weeks. Patients also undergo radiotherapy once daily, 5 days a week, for 6.5 weeks. Cohorts of 3-6 patients receive an escalating number of doses of motexafin gadolinium until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose-limiting toxicity. Patients are followed at 4 weeks and then every 3 months thereafter. PROJECTED ACCRUAL: A maximum of 35 patients will be accrued for this study.
