Lower leg growth rate was assessed in growth population as change in the lower leg length from start to end of each 2-week period, divided by time interval (number of days) between the two measurements, multiplied by 7.

The ACT is a validated self-completed questionnaire consisting of 5 questions that evaluate asthma control during the past 4 weeks on a 5-point categorical scale. Total scores are calculated from the sum of the scores from the 5 questions and can range from 5 to 25, with higher scores indicating better control. An ACT total score of 5 to 19 suggests that the participant's asthma is unlikely to be well controlled, whilst a score of 20 to 25 suggests that the participant's asthma is likely to be well controlled. Baseline value was the last assessment prior to randomization (Day 0). Change from Baseline was post-dose visit value minus the Baseline value. Least square mean change is presented.

Asthma symptom scores (SS) were recorded by par using ratings 0 (no symptoms) to 5-symptoms so severe that par could not perform normal activity \[morning\] or to 4-symptoms so severe that par could not sleep at all \[nightly\]. Withdrawal due to poorly-controlled(WPC) (required step-up therapy) asthma was defined as asthma worsening/exacerbation or ≧3 per week of : day symptoms on ≧ 2 days, rescue use on ≧2 days, morning PEF \<80 % of best effort on ≧ 1 day, night symptoms on ≧1 or more day, a best pre-bronchodilator forced expiratory volume in 1s (FEV1) \< 80% at clinic . Percentage of par WPC asthma at visit 6, 7, 9 and 11 (Week 10, 12, 16 and 20 respectively) were reported. Cox Proportional Hazards Model was used with covariates of Baseline FEV1, gender, age and treatment group. Analysis was descriptive only, no p -values calculated, treatment differences and associated 95% CI were produced.

Asthma symptom scores(SS) were recorded by par using ratings 0 (no symptoms) to 5-symptoms so severe that par could not perform normal activity\[morning\] or to 4-symptoms so severe that par could not sleep at all\[nightly\]. "Well-controlled asthma" was defined as having no exacerbation/asthma worsening, no night-time symptoms, a best pre-bronchodilator forced expiratory volume in 1 second ≥80% at clinic, and ≥2 per week of: daytime symptoms on ≤1 day, rescue use on ≤1 day, or morning peak expiratory flow ≥80% of the best effort value. "Well-controlled asthma" at the end of period 2 was assessed in the week prior to Visit 11 (Week 20). Percentage of participants were calculated as the number of participants with "well-controlled asthma" divided by total number participants excluding withdrawals prior to visit 11 (end of period 2) other than asthma worsening/exacerbation. A Logistic Regression Model was used with covariates of Baseline FEV1, gender, age and treatment group.

The ACT is a validated self-administered questionnaire utilizing 5 questions to assess asthma control during the past 4 weeks on a 5-point categorical scale (1 to 5).

An ACT score of \<=15 showed poorly controlled asthma; 16 to 19 showed partly controlled asthma and \>=20 showed well controlled asthma. The total score was calculated as the sum of the scores from all 5 questions. The primary efficacy analysis (PEA) Population is defined as all Intent-to-Treat (ITT) participants (that is, all participants who were randomized and received at least one prescription of study medication) who have an ACT total score of \<20 at Baseline (Day 0). The percentage of responders that is participants with an ACT total score \>=20 or an increase from Baseline of \>=3 has been presented

From the plasma concentration-time data the following PK parameters will be determined as data permits: Area Under Curve from pre-dose to infinite time (AUC)(0-inf), Area Under Curve from pre-dose to time of last quantifiable concentration (AUC)(0-t), maximum plasma concentration (Cmax)
