What was measured

The apparent volume of distribution after oral administration (Vz/F) calculated as the dose divided by AUCinf times ƒz, where ƒz was the first-order terminal rate constant estimated via linear regression of the terminal log-linear phase. PK samples obtained on the following schedule: Phase 1b Continuous Dosing, Cycles 1 and 2: Day 1: pre-dose, post-dose at 15 and 30 minutes, 1, 2, 4, 6, and 8 hours post-dose plus pre-dose on Day 2 Phase 1b Step-up Dosing, Day 1: pre-dose, post-dose at 15 and 30 minutes, 1, 2, 4, 6, and 7 hours post-dose plus pre-dose on Day 2 Phase 2, Day 1: pre-dose, post-dose at 15 and 30 minutes, 1, 2, 4, 6, and 7 hours post-dose plus pre-dose on Day 2
