Healthy volunteers: no

Brief summary:
The purpose of this study is to find out what effects, good and/or bad, sunitinib has on patients and their tumors. At this time, no drugs are routinely used to treat meningioma, hemangioblastoma or hemangiopericytoma. Only surgery and radiation therapy are known to be useful.

Sunitinib is a drug approved for advanced kidney cancer. Sunitinib is also being studied for other tumors. It may be useful in the treatment of brain tumors because it can prevent formation of new blood vessels that allow tumor cells to survive and grow.

Detailed description:
This is a phase II study of Sunitinib in patients with recurrent or inoperable meningiomas. An exploratory study will be performed for patients with recurrent hemangiopericytoma or hemangioblastoma. There will be approximately 50 patients enrolled on this study (40 meningiomas and 10 hemangiopericytomas/hemangioblastomas). The treatment plan is to use daily SU11248 at a dose of 50 mg, using the established schedule of 4 weeks of treatment followed by two weeks of rest period, forming a six-week treatment cycle. A medical professional will see each patient at least every six weeks while on the medication for toxicity assessment and physical examination. Extent of disease evaluations will occur at baseline, two weeks, twelve weeks, 24 weeks, and every twelve weeks thereafter. These evaluations will include MRI of the brain (or CT head if a patient cannot undergo MRI) and MR perfusion.

Arms:
arm 1: Sunitinib will be administered at a dose of 50 mg orally once daily for four consecutive weeks, followed by a two-week rest period. Intra-patient dose reduction may be required depending on the type and severity of individual toxicity encountered. Imaging studies will be performed after every other cycle. Patients may continue on study as long as they are tolerating treatment and in the absence of disease progression.

Interventions: intervention 1: Sunitinib
Intervention descriptions: intervention 1: The study drug will be administered on an outpatient basis. The starting dose will be 50 mg daily for 28 days (4 consecutive weeks) followed by 14 days off for patients not on CYP3A4 inducers or inhibitors. A cycle equals 42 days.
