Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Comparison of Observed and Predicted Trough Dabigatran Plasma Concentrations at Steady State (C Trough,ss) at Week 1
Time Frame: Week 1
|
Comparisons between dabigatran trough plasma levels as predicted by simulations to those observed in the study are performed to validate the dosing algorithm for Dabigatran Etexilate (DE) . Despite the primary endpoint only being assessed in patients who received dabigatran etexilate, Warfarin was included as a comparator treatment in this study in order to facilitate informal comparisons of outcome events, and to look for efficacy signals in this previously unexplored population. |
Week 1
|
Comparison of Observed and Predicted Trough Dabigatran Plasma Concentrations (C Trough,ss) at Week 2
Time Frame: Week 2
|
Comparisons between dabigatran trough plasma levels as predicted by simulations to those observed in the study are performed to validate the dosing algorithm for Dabigatran Etexilate (DE). Despite the primary endpoint only being assessed in patients who received dabigatran etexilate, Warfarin was included as a comparator treatment in this study in order to facilitate informal comparisons of outcome events, and to look for efficacy signals in this previously unexplored population. |
Week 2
|
Comparison of Observed and Predicted Trough Dabigatran Plasma Concentrations (C Trough,ss) at Week 4
Time Frame: Week 4
|
Comparisons between dabigatran trough plasma levels as predicted by simulations to those observed in the study are performed to validate the dosing algorithm for Dabigatran Etexilate (DE). Despite the primary endpoint only being assessed in patients who received dabigatran etexilate, Warfarin was included as a comparator treatment in this study in order to facilitate informal comparisons of outcome events, and to look for efficacy signals in this previously unexplored population. |
Week 4
|
Comparison of Observed and Predicted Trough Dabigatran Plasma Concentrations (C Trough,ss) at End of Trial (EoT) at Week 12
Time Frame: Week 12
|
Comparisons between dabigatran trough plasma levels as predicted by simulations to those observed in the study are performed to validate the dosing algorithm for Dabigatran Etexilate (DE). (As the trial was stopped prematurely, EOT may not be 12 weeks after randomisation for most of the patients) Despite the primary endpoint only being assessed in patients who received dabigatran etexilate, Warfarin was included as a comparator treatment in this study in order to facilitate informal comparisons of outcome events, and to look for efficacy signals in this previously unexplored population. |
