Trial Overview

Trial Outcomes

Assessment of Duration of EXACT-PRO Events in Part B

Duration is the length of time in days from onset to recovery. It was calculated as the difference in days between day of onset and day of recovery. Onset of event was identified as either an increase in EXACT-PRO score of >=12 points above the par. current mean Baseline for 2 consecutive days, with Day 1 of the 2 days serving as Day 1 onset of the event, or an increase of >=9 points above the par. current mean Baseline for 3 consecutive days, with Day 1 of the 3 days serving as Day 1 onset of the event. Duration was 3-day rolling average was used, which was initiated on Day 1 of onset and ended on Day 1 of Recovery. Recovery was defined as the first day in which par. experienced a persistent, sustained improvement in their condition i.e. decrease in the rolling average EXACT-PRO total score >=9 point from the maximum observed value (highest rolling average EXACT-PRO total score observed the first 14 days of the event) during the first 14 days of an event that is sustained for 7 days.

Number of EXACT-PRO Exacerbations Per Year in Part B

EXACT-PRO is a 14 item patient reported outcome instrument designed to capture information on the occurrence, frequency, severity, and duration of COPD exacerbations. The total score for EXACT-PRO ranges from 0-100, higher scores indicate more severe symptoms. For par. with less than 364 days on-treatment, the annual exacerbation rate was imputed as the number of recorded on-treatment exacerbations, divided by the number of 4-week treatment period intervals for which the par. was in the study, multiplied by 13. For par. with 364 or more days on-treatment, the annual exacerbation rate was calculated as the number of recorded exacerbations between study days 1 and 364. Statistical analysis was done using a Bayesian Cox model, assuming a negative binomial distribution for the underlying exacerbation rate. The exacerbation rates and the ratio (danirixin/placebo), were estimated and 95 percent credible intervals were produced using non-informative priors. 1 par. was excluded from analysis. (NCT02130193)
Timeframe: Up to Day 392 in Part B

HCRU COPD exacerbations are defined as moderate or severe exacerbations based on requirement of new prescription antibiotics or oral corticosteroids, hospitalization or emergency room visits for management of COPD exacerbation. For par. with less than 364 days on-treatment, the annual exacerbation rate was imputed as the number of recorded on-treatment exacerbations, divided by the number of 4-week treatment period intervals for which the par. was in the study, multiplied by 13. For par. with 364 or more days on-treatment, the annual exacerbation rate was calculated as the number of recorded exacerbations between study days 1 and 364. Statistical analysis was done using a Bayesian Cox model, assuming a negative binomial distribution for the underlying exacerbation rate.
