5. Study Description

Brief Summary
This is a study with two sequential cohorts, each with three treatment periods. Single doses of PF-06649751 will be tested in this study, starting at a low dose and escalating to a dose projected to be under the current limits for drug concentration. Each cohort will aim to achieve approximately 9 completers. Primary endpoint is safety and tolerability, secondary endpoint is MDS-UPDRS part III.
