Trial Information

Phase I Brachytherapy Dose Escalating Study Using the Proxima Therapeutics, Inc. GliaSite RTS in Patients With Recurrent Malignant Gliomas


OBJECTIVES:

- Determine the maximum tolerated dose of brachytherapy using an intracavitary applicator
and liquid iodine I 125 in patients with recurrent malignant glioma.

- Determine the acute and chronic toxicity of this therapy in these patients.

OUTLINE: This is a dose-escalation, multicenter study.

Within 3-21 days after surgical resection, patients receive brachytherapy using an
intracavity balloon application (GliaSite) with iodine I 125 solution for a total of 5-7
days.

Cohorts of 5-10 patients receive escalating doses of brachytherapy until the maximum
tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which
at least 2 of 10 patients experience dose-limiting toxicity.

Patients are followed at 4 weeks and then every 2 months for 1 year.

PROJECTED ACCRUAL: Approximately 20-30 patients will be accrued for this study.
