during the interim analysis, resulting in a total of 108 patients
randomized
into the study. Analyses included data from both
cross-over groups across both treatment periods for each
patient included.
All pharmacodynamic (PD) endpoints, including exercise
tolerance and spirometry endpoints, were analyzed using an
analysis of covariance mixed model with sequence, period,
baseline covariate, and treatment as a fixed effect and patient
as a random effect. Patients were included in the PD analysis
set if they completed at least one treatment period, had an
evaluable PD assessment on Day 21 of this period, and had
no major protocol deviation impacting primary PD assessment.
Treatment least-squares means (LSM), LSM difference
(NVA237–placebo), and corresponding 95% confidence
intervals (CI) were estimated.
