Conditions: Anaplastic Astrocytoma Glioblastoma
Keywords: Sutent
Allocation: NA | Intervention model: SINGLE_GROUP
Enrollment: 30
Healthy volunteers: no

Brief summary:
We are asked patients to take part in this study because they had recurrent (returned) (1st or 2nd) anaplastic astrocytoma (AA) or glioblastoma multiforme (GBM).

The purposes of this study are:

* To see if Sutent has any change on the patient and their cancer.
* To see if Sutent will slow or stop the growth of their tumor.
* To measure the safety of Sutent. Sutent is Food and Drug Administration (FDA) approved to treat patients with a gastrointestinal stromal tumor after the disease worsened while taking another medicine called imatinib mesylate or when imatinib mesylate cannot be taken. Sutent is also FDA approved to treat patients with advanced renal cell carcinoma. At this time, it is not known whether Sutent will improve symptoms, or help patients with this disease live longer.

Detailed description:
Trial patients received sunitinib 50 mg daily for 4 weeks without regard to meals, followed by a 2-week rest period. This 6-week regimen constituted 1 cycle. Patients were treated for up to 9 cycles \[\~ year) or until disease progression or death or if persistent toxicities occurred. Complete blood count with differential, complete metabolic profile, neurologic exam, and brain magnetic resonance imaging (MRI) with contrast were obtained after each cycle. Toxicity assessments were obtained after each cycle. Toxicity was graded according to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE), version 3.0.

Arms:
arm 1: Sutent was administered daily for 4 weeks at a dose of 50 mg followed by a 2 week study drug free break.

Interventions: intervention 1: Sunitinib Malate
Intervention descriptions: intervention 1: Initially, patients were started on sunitinib at a dose of 50 mg daily. If 50 mg daily resulted in unacceptable toxicity, 2 dose modifications were allowed (to 37.5 and to 25 mg daily, if necessary). Study patients who could not tolerate 25 mg daily of sunitinib were taken off study.
