What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Maximum Plasma Concentration (Cmax) |  | Pre-dose, 10, 15, 20, 30, 40, 50, 60, 70, 80, 90, 105, 120, 180, 240, 360, 480, 720 and 1440 mins (Day 1, Post-dose) | 
| Area Under the Plasma Concentration-time Curve From Administration to the Last Quantifiable Concentration at Time t (AUC0-t) |  | Pre-dose, 10, 15, 20, 30, 40, 50, 60, 70, 80, 90, 105, 120, 180, 240, 360, 480, 720 and 1440 mins (Day 1, Post-dose) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Elimination Rate Constant (Kel) |  | Pre-dose, 10, 15, 20, 30, 40, 50, 60, 70, 80, 90, 105, 120, 180, 240, 360, 480, 720 and 1440 mins (Day 1, Post-dose) | 
| AUC From Administration to Infinity (AUC0-inf) | AUC0-inf = AUC0-t + (Ct/Kel), where Ct was the last quantifiable concentration at time t. | Pre-dose, 10, 15, 20, 30, 40, 50, 60, 70, 80, 90, 105, 120, 180, 240, 360, 480, 720 and 1440 mins (Day 1, Post-dose) | 
| Ratio of AUC0-t/AUC0-inf (AUCR) |  | Pre-dose, 10, 15, 20, 30, 40, 50, 60, 70, 80, 90, 105, 120, 180, 240, 360, 480, 720 and 1440 mins (Day 1, Post-dose) | 
| Time to Cmax (Tmax) |  | Pre-dose, 10, 15, 20, 30, 40, 50, 60, 70, 80, 90, 105, 120, 180, 240, 360, 480, 720 and 1440 mins (Day 1, Post-dose) | 
| Plasma Concentration Half-life (T1/2) | Terminal elimination half-life (T1/2) = ln(2)/Kel | Pre-dose, 10, 15, 20, 30, 40, 50, 60, 70, 80, 90, 105, 120, 180, 240, 360, 480, 720 and 1440 mins (Day 1, Post-dose) | 
| Plasma Concentration at Each Planned Nominal Time-point (Cn) | Cn was derived using linear interpolation from the 2 samples taken either side of the nominal time where there was a sampling time deviation. For concentrations that were missing due to blood samples not being taken Cn was not derived. | Pre-dose, 10, 15, 20, 30, 40, 50, 60, 70, 80, 90, 105, 120, 180, 240, 360, 480, 720 and 1440 mins (Day 1, Post-dose) | 
| Number of Subjects With Adverse Events (AEs). | Intensity was determined by the Investigator. For symptomatic AEs the following definitions were applied. Mild = AE did not limit usual activities; subject may have experienced slight discomfort. Moderate = AE resulted in some limitation of usual activities; subject may have experienced significant discomfort. Severe = AE resulted in an inability to carry out usual activities; subject may have experienced intolerable discomfort/pain. Relationship to Investigational Medicinal Products (IMP) Unassessable/Unclassified = Insufficient information to be able to make an assessment. Conditional/ Unclassified = Insufficient information to make an assessment at present. Unrelated = No possibility that AE was caused by IMP. Unlikely = Slight, but remote, chance that AE was caused by IMP. Possible = Reasonable suspicion that the AE was caused by IMP. Probable = Most likely that AE was caused by IMP. Certain = AE was definitely caused by IMP. | Up to follow-up day 7 |
