Brief summary
This was a Phase I, single centre, open-label, non-randomised study and was designed to be conducted in up to 2 parts. The purpose of Part 1 was to identify a MR formulation of PCS499 that would provide an optimal dosing regimen in patients. The purpose of Part 2 of the study was to generate repeat dose information for the selected MR formulation of PCS499 in order to provide additional PK information for future patient studies.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Maximum plasma concentrations (Cmax) for Part 1 | Blood samples will be drawn prior to single dose administration of study drug and at 11 other timepoints in a 24 hour period. | Serial blood sampling at specified time points for determination of plasma concentration-time profiles |
| Maximum plasma concentrations (Cmax) in Part 2 | Blood sampling will be drawn prior to the single dose administration on Days 1 & 4 and at 11 other timepoints in the following 24 hours. In addition, pre-dose trough samples will be taken on Days 2 &3. | Serial blood sampling at specified time points for determination of plasma concentration-time profiles |
