Trial Information

Phase II Study of Proton Radiation Therapy for Low Grade Gliomas

Proton radiation will be delivered daily for approximately 6 weeks. Subjects will be
assessed weekly for side effects. Each visit will take about 15 minutes.

Subjects will have follow-up visits at 3, 6, 12, 24, 36, 48, 60, 72, and 84 months after
their last proton radiation treatment. They will receive a physical exam, have blood tests
(about 4 teaspoons) and answer questionnaires regarding medical history, quality of life,
and emotional well-being. Subjects will also receive a neurocognitive exam (a limited exam
at 6 months, and full exam annually).

Inclusion Criteria:

- Histologically confirmed low-grade gliomas

- Subject must be indicated for radiation therapy

- Life expectancy greater than 5 years

- Willing to participate in rigorous neurocognitive evaluations at baseline and
serially following treatment

- Able to speak and comprehend English

- Recovered from adverse events due to agents administered more than 4 weeks before
entering study

- Able to undergo MRI scans

Exclusion Criteria:

- Prior cranial radiation therapy

- Baseline neurocognitive or emotional disorders

- Uncontrolled intercurrent illness

- History of a different malignancy unless disease-free for at least 5 years

- HIV positive on antiretroviral therapy
