Alternate Title

Motexafin Gadolinium Plus Radiation Therapy in Treating Children With Newly Diagnosed Brain Stem Glioma

Basic Trial Information

Objectives

1. Determine the maximum tolerated dose (MTD) and schedule of motexafin gadolinium administered prior to radiotherapy in children with newly diagnosed diffuse intrinsic pontine glioma.
2. Determine the toxic effects of this drug given at the MTD in these patients.
3. Determine the intratumor and brain distribution of this drug by MRI in these patients.

Radiotherapy:

• No prior cranial radiotherapy

Surgery:

Expected Enrollment

A maximum of 24 patients will be accrued for this study within 2 years.

Outline

This is a dose-escalation study of motexafin gadolinium.

Approximately 2-5 hours before radiotherapy, patients receive motexafin gadolinium IV over 5 minutes. Patients undergo radiotherapy 5 days a week for 6 weeks.

Cohorts of 3-6 patients receive escalating doses of motexafin gadolinium until the maximum tolerated dose (MTD) is determined. The first cohort receives motexafin gadolinium 5 days a week for 3 weeks; the second cohort receives motexafin gadolinium 3 days a week for 6 weeks; and subsequent cohorts receive motexafin gadolinium 5 days a week for 6 weeks. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity.

Patients are followed every 3 months for up to 3 years.
