ListOutcomeTime frameDescription
PrimaryThe Primary Efficacy Variable Was the AAC for Daily EXACT Scores During the 12-week Treatment Period.12 weeks
The primary variable (endpoint) of this study is the difference in the Area Above the Curve (AAC) for the daily EXACT score from baseline to Week 12 between subjects treated with AQX-1125 and placebo.The EXACT questionnaire is a patient reported outcome (PRO) measure designed to standardise the method for evaluating the frequency, severity and duration of acute exacerbations of COPD. The EXACT is a 14-item daily questionnaire where each item is assessed on a 5 or 6 point ordinal scale. Participants completed the EXACT questionnaire on a daily basis via an electronic diary from Day 1 (pre-dose) to Day 84 (week 12). Higher scores on the daily EXACT questionnaire indicate a more severe health state. When the post-treatment EXACT scores are lower (i.e. improved symptoms) than baseline EXACT, the AACs are positive.
SecondaryChange From Baseline in COPD Assessment Tool (CAT) Score12 weeks
The secondary objective is to evaluate the treatment effect of once daily administrations of AQX-1125 compared to placebo over 12 weeks on the COPD Assessment Tool (CAT) score.The CAT questionnaire measures the impact of COPD on wellbeing and daily life. Participants answer 8 questions on a scale from 0 (best) to 5 (worst). The total score ranges from 0 to 40 with higher scores indicating more impact. A negative change from baseline indicates improvement. The change in total CAT score from Day 1, before taking study drug (baseline), to end of the 12 week treatment period was compared between the two treatments using an ANOVA model adjusting for treatment and region and including the baseline score as a covariate.
SecondaryAnalysis of the Number of COPD Exacerbations (Medically Treated Event (MTE))12 weeks
The secondary objective is to evaluate the treatment effect of once daily administrations of AQX-1125 compared to placebo over 12 weeks on the number of COPD exacerbations (MTE). COPD exacerbations were referred to as Medically Treated Exacerbations (MTEs) and identified as a change in symptoms and/or signs of COPD requiring prescription of one or both of: (1) Course of oral corticosteroids or (2) Antibiotic(s).
SecondaryTime to First COPD Exacerbation12 weeks
The secondary objective is to evaluate the treatment effect of once daily administrations of AQX-1125 compared to placebo over 12 weeks on the time to first exacerbation requiring medical intervention of oral corticosteroids and/or antibiotics.
SecondaryThe Number of Subjects With at Least One COPD Exacerbation.12 weeksThe number of subjects that presented with a COPD exacerbation during the 12 week treatment period.
SecondaryChange From Baseline in FEV112 weeks
The secondary objective is to evaluate the treatment effect of once daily administrations of AQX-1125 compared to placebo over 12 weeks on forced expiratory volume in 1 second \[FEV1\]. FEV1 was determined from post-bronchodilator spirometry testing done at clinic visits.
SecondaryAQX-1125 Concentrations in Plasma (Trough Values)12 weeksThe secondary objectives are to evaluate the pharmacokinetics (PK) of AQX-1125 in plasma.
