SU5416 in Treating Patients With Recurrent Astrocytoma or Mixed Glioma That Has Not Responded to Radiation Therapy
RATIONALE: SU5416 may stop the growth of astrocytoma or glioma by stopping blood flow to the tumor.
PURPOSE: Phase I/II trial to study the effectiveness of SU5416 in treating patients who have recurrent astrocytoma or mixed glioma that has not responded to previous radiation therapy.

|Study Design:||Primary Purpose: Treatment|
|Official Title:||A Phase I/II Trial of SU5416 in Patients With Recurrent High Grade Astrocytomas or Mixed Gliomas|
|Study Start Date:||February 2000|
OBJECTIVES: Phase I:
- Determine the maximum tolerated dose of SU5416 in patients with recurrent malignant glioma who are, as well as those who are not, taking enzyme-inducing antiepileptic drugs.
- Determine the toxic effects (safety profile) of this drug in this patient population.
- Characterize the pharmacokinetics of this drug in these patients.
- Develop exploratory data relative to surrogate endpoints of angiogenic activity in vivo, including functional imaging and in vitro assays of endothelial cell inhibition and serum angiogenic peptides.
- Determine the efficacy of SU5416, in terms of 6-month progression-free survival, in patients with recurrent high-grade glioma.
- Determine, further, the safety profile of the phase II dose of this drug in this patient population.
- Develop exploratory data relative to surrogate endpoints of angiogenic activity in vivo including functional imaging and in vitro assays of endothelial cell inhibition and serum angiogenic peptides.
OUTLINE: This is a dose-escalation, multicenter study. Patients are stratified according to concurrent enzyme-inducing antiepileptic drugs (no vs yes).
Patients receive SU5416 IV on days 1 and 4 weekly for 4 weeks. Courses repeat every 4 weeks in the absence of unacceptable toxicity or disease progression.
Cohorts of 3-6 patients receive escalating doses of SU5416 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 has been determined, additional patients are accrued to the phase II portion of the study. These patients receive SU5416 IV, as in the phase I portion, at the appropriate MTD established in phase I.
Patients are followed for survival.
PROJECTED ACCRUAL: At least 30 patients will be accrued for the phase I dose-escalation portion of this study within 10 months. An additional 48 patients (32 with glioblastoma multiforme and 16 with anaplastic glioma) will be accrued for the phase II portion of this study within 6-8 months.
