Brief Summary:

A dose escalation scale consisting of 5 dosage levels is being used to determine the maximum tolerated dose (MTD) of SU101. A minimum of 3 and a maximum of 6 patients will be enrolled at each dose level. MTD is defined as the dose level immediately below that at which 2 or more patients exhibit dose limiting toxicity.

Each treatment cycle is 21 days. Patients receive a 96 hour continuous IV infusion of SU101 on days 1-4.

Condition or disease Intervention/treatment Phase
Glioma Sarcoma Drug: SU101 Phase 1

Detailed Description:
SU101 is a member of a novel class of antineoplastic agents, platelet-derived growth factor (PDGF) receptor inhibitors. Preclinical data suggests that SU101 might be an effective agent against neuroglial tumors as well as a variety of sarcomas. A pediatric phase I trial of SU101 in children with these malignancies will be conducted to find the maximum tolerated dose of SU101 and define the toxicity profile of this agent. In addition, we will define the pharmacokinetics of SU101 and its active metabolite SU0020 in pediatric patients and gather preliminary information regarding response.
