Based on non-compartmental PK evaluation. The AUC(0-tlast) \[Area Under the Concentration-time Curve After Single (First) Dose From Time Zero to the Last Data Point \>LLOQ (Lower Limit of Quantification)\] is a measure of systemic drug exposure from time 0 up to the time point at which the last measurable drug could be detectable, which is obtained by collecting a series of blood samples and measuring the concentrations of drug in each sample.

Time frame: Days 1-5: Pre-dose, 0.5, 1, 2, 4, 6, 8, 10, 24, 48 and 96 hours post-dose
