E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to evaluate the efficacy and safety of adding GSK2190915 100mg, GSK2190915 300mg or placebo tablets administered once daily to fluticasone propionate 100mcg inhalation administered twice daily in uncontrolled asthmatic subjects > or = 12 years of age over the course of 6 weeks treatment. |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary efficacy endpoint was trough (AM pre-dose and pre-rescue bronchodilator) forced expiratory volume in 1 second (FEV1) at the end of the 6-week treatment period. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
Secondary efficacy endpoints comprised daily trough (AM pre-dose and pre-rescue bronchodilator) peak expiratory flow (PEF), daily PM PEF, daily asthma symptom score and daily rescue salbutamol use averaged over the last 3 weeks of the 6-week treatment period, percentage of symptom-free days and nights, rescue-free days and nights, nights without awakenings due to asthma and proportion of subjects withdrawn due to lack of efficacy during the last 3 weeks of the 6-week treatment period.
Other secondary endpoints were mean change from baseline in Asthma Control Questionnaire (ACQ-6) and Asthma Quality of Life Questionnaire (AQLQ12+) scores.
Safety endpoints comprised adverse events (AEs), haematology, chemistry (including liver function tests) and urinalysis parameters, physical examination, and vital signs (pulse rate and systolic and diastolic blood pressure). |
