| Main Objective: The primary objective is to compare the relative dose potency of HFA vs CFC pMDI budesonide on airway responsiveness to methacholine.; Secondary Objective: Secondary objectives include assessment of the effect of the two treatments on · airway responsiveness to methacholine, · spirometry, · exhaled nitric oxide , · asthma symptoms, · PEF and the · ratio of overnight urinary cortisol to creatinine. Assessment of safety will include reports of serious adverse events and discontinuations due to adverse event. ; Primary end point(s): The primary efficacy endpoint is the methacholine airway responsiveness measured as PC20. This is recorded at first baseline (the end of the run-in; prior to Treatment 1), during treatment period 1 (i.e., after the first 2 weeks on 200 µg and after the second 2 weeks on 800 µg), at second baseline (the end of the washout; prior to Treatment 2) and during treatment period 2 (i.e., after the first 2 weeks on 200 µg and after the second 2 weeks on 800 µg). Following a log2 transformation, the change in PC20 from pooled baseline will be compared between treatments at each dose using an Analysis of Variance (ANOVA), with patient, period and treatment in the model. The HFA and CFC formulations will be compared at each dose level. Other efficacy measures will be analysed using the same model, but without log2 transformation (with the exception for eNO), and 95% confidence intervals for the differences between doses at each level will be calculated. For diary variables, pooled baselines will not be used in the analyses (i.e. these variables will not be expressed as changes from pooled baseline). Cortisol values will be log-transformed prior to analysis and analysed using the same model as above. For PC20, the primar | — |
