A Safety Study in Healthy Volunteers to Evaluate Safety, How Fast the Drug is Absorbed, and the Side Effects of the Drug in Humans

The purpose of this study is to characterize more fully the safety, tolerability and pharmacokinetics of single and repeat oral doses of pazopanib at lower doses than those previously studied. The first part of the study is designed as an open-label, non-randomized, single session, parallel-group, sequential dose-rising to investigate pharmacokinetics of single oral doses in healthy adult subjects. In the second part of the study, healthy elderly subjects will participate in one 14 day repeat-dose session, randomized to receive either pazopanib or placebo. Dose escalation within Part 2, is based upon emerging safety and PK data from each preceding repeat dosing cohort from at least 7 days of safety data as well as emerging safety and PK data from single dose. The elderly population chosen for the second part of the study will more closely reflect the target population for the AMD indication. The results from the current study will assist in the dose selection of the subsequently planned study in patients with AMD.
