Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Area Under Plasma Concentration-time at Time t (AUC0-t)	AUC0-t defines Area under the plasma concentration-time curve (AUC) from administration to the last quantifiable concentration at time t.	Pre-dose and at 15 mins, 30 mins, 45 mins, 1 hour, 1 hour 15 mins, 1 hour 30 mins, 1 hour 45 mins, 2 hours, 2 hours 30 mins, 3, 4, 6, 9, 15 (Day 1), 24, 36 (Day 2), 48 (Day 3) and 72 (Day 4) hours post-dose
Primary	Maximum Plasma Concentration (Cmax)		Pre-dose and at 15 mins, 30 mins, 45 mins, 1 hour, 1 hour 15 mins, 1 hour 30 mins, 1 hour 45 mins, 2 hours, 2 hours 30 mins, 3, 4, 6, 9, 15 (Day 1), 24, 36 (Day 2), 48 (Day 3) and 72 (Day 4) hours post-dose
Secondary	Elimination Rate Constant (Kel)	Elimination Rate Constant (Kel) was calculated as the absolute value of the log-linear regression slope of the elimination phase (logged) over time (linear) using the post Cmax concentrations [at least 3 non-below the limit of quantification (BLQ)] that maximised the adjusted R2.	Pre-dose and at 15 mins, 30 mins, 45 mins, 1 hour, 1 hour 15 mins, 1 hour 30 mins, 1 hour 45 mins, 2 hours, 2 hours 30 mins, 3, 4, 6, 9, 15 (Day 1), 24, 36 (Day 2), 48 (Day 3) and 72 (Day 4) hours post-dose
Secondary	Area Under the Plasma Concentration Curve From Administration to Infinity (AUC0-inf)	Area under the plasma concentration curve from administration to infinity (AUC0-inf) was calculated as AUC0-t + (Ct/Kel) where Ct was the last quantifiable concentration at time t	Pre-dose and at 15 mins, 30 mins, 45 mins, 1 hour, 1 hour 15 mins, 1 hour 30 mins, 1 hour 45 mins, 2 hours, 2 hours 30 mins, 3, 4, 6, 9, 15 (Day 1), 24, 36 (Day 2), 48 (Day 3) and 72 (Day 4) hours post-dose
Secondary	Residual Area (AUC%Extrap)	AUC%extrap represents the percentage of the AUC0-inf obtained by extrapolation, calculated as (1 - [AUC0-last/AUC0-inf]) multiplied by 100.	Pre-dose and at 15 mins, 30 mins, 45 mins, 1 hour, 1 hour 15 mins, 1 hour 30 mins, 1 hour 45 mins, 2 hours, 2 hours 30 mins, 3, 4, 6, 9, 15 (Day 1), 24, 36 (Day 2), 48 (Day 3) and 72 (Day 4) hours post-dose

Secondary	Plasma Concentration (Elimination) Half-life (T1/2)		Pre-dose and at 15 mins, 30 mins, 45 mins, 1 hour, 1 hour 15 mins, 1 hour 30 mins, 1 hour 45 mins, 2 hours, 2 hours 30 mins, 3, 4, 6, 9, 15 (Day 1), 24, 36 (Day 2), 48 (Day 3) and 72 (Day 4) hours post-dose
Secondary	Plasma Concentration at Each Planned Nominal Time-point (Cn)		Pre-dose and at 15 mins, 30 mins, 45 mins, 1 hour, 1 hour 15 mins, 1 hour 30 mins, 1 hour 45 mins, 2 hours, 2 hours 30 mins, 3, 4, 6, 9, 15 (Day 1), 24, 36 (Day 2), 48 (Day 3) and 72 (Day 4) hours post-dose
Secondary	Occurrence of Adverse Events (AEs)	Intensity was determined by the Investigator; Mild = AE does not limit usual activities; subject may experience slight discomfort.; Moderate = AE results in some limitation of usual activities; subject may experience significant discomfort.; Severe = AE results in an inability to carry out usual activities; subject may experience intolerable discomfort or pain.; Relationship to Investigational Medicinal Products (IMP); Certain = AE was definitely caused by IMP. Probable = Most likely that the AE was caused by IMP. Possible = Reasonable suspicion that the AE was caused by IMP Unlikely = Slight, but remote, chance that the AE was caused by IMP but the balance of judgment is that it was most likely not due to the IMP.; Unrelated = No possibility that the AE was caused by IMP Un-assessable/Unclassified = Insufficient information to be able to make an assessment.; Conditional/Unclassified = Insufficient information to make an assessment at present.	Up to follow-up day 7
