Purpose
This phase I/II trial is studying the side effects and best dose of vorinostat and to see how well it works when given together with radiation therapy followed by maintenance therapy with vorinostat in treating younger patients with newly diagnosed pontine gliomas. Vorinostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving vorinostat together with radiation therapy may kill more tumor cells

Experimental: Arm I
Patients receive vorinostat orally or IV on days 1-5, 8-12, 15-19, 22-26, 29-33, and 36-40. Patients undergo 3D-conformal or intensity-modulated radiotherapy 5 days per week for 6 weeks. Patients then receive maintenance therapy comprising oral vorinostat on days 1-28. Treatment repeats every 28 days for 12 courses in the absence of disease progression or unacceptable toxicity.

Detailed Description:
PRIMARY OBJECTIVES:
l. To estimate the maximum-tolerated dose (MTD) or recommend a phase II dose of vorinostat given concurrently with radiotherapy in pediatric patients with newly diagnosed intrinsic pontine gliomas.
II. To define and describe the toxicities of vorinostat given concurrently with radiotherapy in these patients.
III. To determine, in the context of a this phase I/II trial, the antitumor activity of combining vorinostat with radiotherapy followed by maintenance vorinostat for 12 courses in these patients, as measured by 12-month event-free survival and overall survival.
IV. To determine the toxicities of vorinostat for 12 additional courses after completion of concurrent vorinostat and radiotherapy.
SECONDARY OBJECTIVES:
I. To measure non-homologous end-joining (NHEJ) activity in peripheral blood mononuclear cells (PBMCs) before treatment, at 2 weeks after starting vorinostat and radiotherapy, and at the end of radiotherapy.
II. To measure HDAC2 levels and assess histone acetylation in PBMCs before treatment, at 2 weeks after starting vorinostat and radiotherapy, and at the end of radiotherapy.
III. To quantify DNA repair proteins from the NHEJ and homologous recombination repair pathways in tumors by either Western analysis or IHC, if paraffin-embedded tumor is available.
OUTLINE: This is a multicenter, phase I, dose-escalation study of vorinostat followed by a phase II study.
Patients receive vorinostat orally or IV on days 1-5, 8-12, 15-19, 22-26, 29-33, and 36-40. Patients undergo 3D-conformal or intensity-modulated radiotherapy 5 days per week for 6 weeks. Patients then receive maintenance therapy comprising oral vorinostat on days 1-28. Treatment repeats every 28 days for 12 courses in the absence of disease progression or unacceptable toxicity.
Blood and tumor samples may be collected periodically for correlative studies.
After completion of study treatment, patients are followed up for up to 5 years.
