PAZIT Study for Children and Young Adults With Relapsed or Refractory Sarcoma

Pazopanib will be administered orally as a tablet according to an assigned dose level per protocol. A cycle will be defined as 21 days. Drug dosing for the tablet formulation will be determined using a study-specific nomogram.

"Patients will be given irinotecan at a dose of 25 mg/m2/dose IV on days 1-5 of a 21-day cycle during Cycle 1. In subsequent cycles, irinotecan may be given intravenously at a dose of 25 to 37.5 mg/m2/dose or orally at a dose of 45 to 67.5 mg/m2/dose on days 1-5 of a 21-day cycle.~Note that some patients enrolled on an earlier protocol version received 50 mg/m2/dose IV on days 1-5 of the first 21-day cycle and then either 50 mg/m2/dose IV or 90 mg/m2/dose orally for subsequent 21-day cycles. This higher dose level is no longer being given to newly enrolled subjects."

Temozolomide will be given at a dose of 100 mg/m2/dose orally on days 1-5 of each 21-day cycle.
