PRIMARY outcome

Timeframe: Assessed over 48 hours post-dose

Population: Pharmacokinetic Analysis Set defined as all subjects in the Safety Analysis Set for whom the primary pharmacokinetic data were considered sufficient and interpretable. Subjects who vomited or experienced significant diarrhea between dosing and 10 hours post-dose were excluded from the pharmacokinetic descriptive statistics and statistical analysis.

Cmax is a term that refers to the maximum (or peak) concentration that a drug achieves in the body after the drug has been administrated.

Area under the plasma concentration versus time curve from time 0 to infinity. AUC can be used as a measure of drug exposure. It is derived from drug concentration and time so it gives a measure how much and how long a drug stays in a body.
