Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Six participants initially received a single dose of AG-013736 5 mg followed by 5 mg twice daily (BID) multiple dosing. They were monitored for dose limiting toxicity (DLT) up to multiple dosing Cycle 1. Since no more than 1 of the first 6 participants had a DLT, 6 additional participants initiated AG-013736 from multiple dosing per the protocol.

Reporting Groups
  Description
AG-013736

Single dose (first 6 participants only): Single AG-013736 5 mg was administered orally.

Multiple dose (all participants): AG-013736 5 mg twice daily (BID) was administered orally in fed state, 12 hours apart at approximately the same time each day. AG-013736 dose was titrated or reduced based on the dose modification criteria: the available dose was 2, 3, 5, 7, or 10 mg at a time. One cycle length was 28 days and participants continued the study treatment until intolerable toxicity or disease progression occurred.

Measure Type Secondary
Measure Title Percent Change From Baseline in Soluble Vascular Endothelial Growth Factor Receptor 2 and 3 (s-VEGFR2 and s-VEGFR3), Vascular Endothelial Growth Factor (VEGF), Soluble Stem Cell Factor Receptor (s-KIT)
Measure Description Percent change from baseline is obtained from (observed value minus baseline value) divided by baseline value multiplied by 100 in each parameter, i.e., VEGFR2, s-VEGFR3, s-KIT, and VEGF.
Time Frame Prior to the initial dose (baseline), Day 1 of Cycle 2 and at the discontinuation
