A Phase II Study of Motexafin-Gadolinium (NSC 695238, IND #55583) and Involved Field Radiation Therapy for Intrinsic Pontine Glioma of Childhood
This phase II trial is studying how well giving motexafin gadolinium together with radiation
therapy works in treating young patients with pontine glioma. Radiation therapy uses
high-energy x-rays to kill tumor cells. Drugs, such as motexafin gadolinium, may make tumor
cells more sensitive to radiation therapy. Giving motexafin gadolinium together with
radiation therapy may kill more tumor cells.

PRIMARY OBJECTIVES:
I. Evaluate the effect of combining motexafin gadolinium with daily fractionated radiotherapy
on 1-year event-free survival of pediatric patients with intrinsic pontine glioma (brain stem
glioma).
SECONDARY OBJECTIVES:
I. Evaluate the effect of combining motexafin gadolinium with daily fractionated radiotherapy
on 1-year overall survival of these patients.
II. Determine the toxicities of motexafin gadolinium in combination with radiotherapy in
these patients.
OUTLINE: This is a multicenter study.
Patients receive motexafin gadolinium IV over 5-10 minutes once daily (prior to radiotherapy)
5 days a week for 6 weeks. Patients undergo focal cranial radiotherapy once daily 5 days a
week for 6 weeks. Treatment continues in the absence of disease progression or unacceptable
toxicity.
After completion of study treatment, patients are followed every 3 months for 3 years and
then periodically thereafter.
