Study Endpoints
Primary Endpoints
Maximum Plasma Concentration (Cmax)
Study Day 1 and Day 28 at 20, 40, and 60 min and at 1.5, 2, 2.5, 3, 4, 6, 8, 10 and 12 h post-dose

Blood draws will be done to evaluate levels of PTI-125 in the plasma using non-compartmental methods in WinNonlin.

Time to Maximum Plasma Concentration (Tmax)
Study Day 1 and Day 28 at 20, 40, and 60 min and at 1.5, 2, 2.5, 3, 4, 6, 8, 10 and 12 h post-dose

Levels of PTI-125 will be assessed to determine how long it takes to reach the Cmax

Last Quantifiable Plasma Concentration (Clast)
Study Day 1 and Day 28 at 20, 40, and 60 min and at 1.5, 2, 2.5, 3, 4, 6, 8, 10 and 12 h post-dose

Levels of PTI-125 will be assessed to determine the last time point where PTI-125 can be detected.

Time to Last Quantifiable Plasma Concentration (Tlast)
Study Day 1 and Day 28 at 20, 40, and 60 min and at 1.5, 2, 2.5, 3, 4, 6, 8, 10 and 12 h post-dose

Levels of PTI-125 will be assessed to determine the elapsed time to where PTI-125 can last be detected in the plasma.

Area Under the Curve (AUClast)
Study Day 1 and Day 28 at 20, 40, and 60 min and at 1.5, 2, 2.5, 3, 4, 6, 8, 10 and 12 h post-dose

AUC for PTI-125 plasma concentration from time zero to the last quantifiable plasma concentration.

Plasma Half-life (T1/2)
Study Day 1 and Day 28 at 20, 40, and 60 min and at 1.5, 2, 2.5, 3, 4, 6, 8, 10 and 12 h post-dose

Assessment of the half-life in plasma of PTI-125
