About this study
Official title: A Two Part, Phase IIa, Randomized, Placebo-controlled Study To Investigate The Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Clinical Efficacy of Oral Danirixin (GSK1325756) in Symptomatic COPD Subjects With Mild to Moderate Airflow Limitation at Risk for Exacerbations
The aim of this First Time in Patient study is to obtain initial information on the safety, tolerability, pharmacokinetics, pharmacodynamics and clinical efficacy of repeat daily administration of danirixin in subjects with symptomatic chronic obstructive pulmonary disease (COPD) having mild to moderate airflow limitation and are at high risk for future COPD exacerbations.
The study will be conducted in two parts. Part A will be a two week open label, single arm study in patients with COPD to obtain pharmacokinetic data and safety information of repeat dosing of danirixin in the population of interest. Approximately 10 subjects will be enrolled in Part A of the study. Progression to and dose selection for Part B will occur following review of the data collected in Part A. Part B will be a 52-week, randomized, double-blind (sponsor unblind), placebo-controlled on top of standard of care, parallel group study. Part B will evaluate several clinical efficacy assessments related to exacerbations and respiratory symptoms. Approximately 100 subjects will be enrolled with a target of 80 subjects completing 52 weeks of danirixin administration.

Number of Health Care Resource Utilization (HCRU) Defined COPD Exacerbations Per Year 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. The exacerbation rates along with the ratio (danirixin/placebo), were estimated and corresponding 95 percent credible intervals were produced using non-informative priors. 1 par. was excluded from the analysis.

Measured: Up to Day 392 in Part B
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.
Measured: Up to Day 392 in Part B
Assessment of Severity of EXACT-PRO Events in Part B
EXACT-PRO tool was used to measure severity of COPD exacerbations in participants. Severity was indicated by the maximum EXACT-PRO total score during the course of event (from day of onset to day of recovery).
Measured: Up to Day 392 in Part B
Monthly Weighted Means of EXACT-RS Domain Scores in Part B
EXACT-RS is a tool which consists of 11 items from the 14 item EXACT-PRO instrument, intended to capture information related to the respiratory symptoms of COPD. EXACT-RS domains included breathlessness, cough and chest symptoms. The EXACT-RS has a scoring range of 0-40, higher scores indicate more severe symptoms. A par. had at least 10 days of diary data in any month to contribute a non-missing weighted mean AUC of daily values; otherwise the weighted mean for that month were considered missing. A mixed effects model in a Bayesian framework with repeated measures were performed. The posterior mean and corresponding 95 percent credible interval were calculated. Only those participants with data available at the specified time points were analyzed (represented by n=X, X in the category titles).
Measured: Up to Day 392 in Part B
Change From Baseline for COPD Assessment Test (CAT) at the Indicated Time Points in Part B
The CAT is a validated, 8 item questionnaire which has been developed designed to measure overall COPD-related health status for the initial assessment and longitudinal follow up of par. with COPD. Participants completed each question by rating their experience on a 6 point scale ranging from 0 (no impairment) to 5 (maximum impairment) with a total scoring range of 0 - 40. CAT was assessed at Baseline (Day 1), Day 28, Day 112, Day 168, Day 280 and Day 364 where Baseline was considered as score on Day 1. The change from Baseline was calculated by subtracting the Baseline values from the individual post-randomization values. Only those participants with data available at the specified time points were analyzed (represented by n=X, X in the category titles).
Measured: Up to Day 392 in Part B
Number of Participants With Physician's Global Assessment (PGA) Readings in Part B
The PGA is a single item clinician reported outcome measure assessing the overall severity of COPD. Physicians rated disease severity on a four point scale ranging from 1-4 (1=mild, 2=moderate, 3=severe, 4=very severe) at Week 0, 4, 8, 16, 24, 40 and 52. Baseline was considered as score on Day 1. A categorical summary of PGA is presented by treatment and visit.Only those participants with data available at the specified time points were analyzed (represented by n=X, X in the category titles).
Measured: Up to Day 392 in Part B
Number of Participants With Patient Global Rating of Severity (PGRS) Score in Part B
PGRS is a single global question and was asked to participants to rate their COPD severity on a four point scale ranging from 1-4 (1=mild, 2=moderate, 3=severe, 4=very severe). Participants completed PGRS at Week 0, 4, 8, 16, 24, 40 and 52. Baseline was considered as score on Day 1. A categorical summary of PGRS is presented by treatment and visit.Only those participants with data available at the specified time points were analyzed (represented by n=X, X in the category titles).
Measured: Up to Day 392 in Part B
Number of Participants With Patient Global Impression of Change (PGIC)Score in Part B
Participants completed a PGIC questions at Week 4, 8, 16, 24, 40 and 52. Response options were on a 7 point Likert scale ranging from much better to much worse. PGIC was re-coded from a categorical to numerical value prior to analysis as: much worse = -3, worse = -2, slightly worse = -1, no change = 0, slightly better = 1, better = 2, much better = 3.A categorical summary of PGIC is presented by treatment and visit.Only those participants with data available at the specified time points were analyzed (represented by n=X, X in the category titles).

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The aim of this First Time in Patient study is to obtain initial information on the safety, tolerability, pharmacokinetics, pharmacodynamics and clinical efficacy of repeat daily administration of danirixin in subjects with symptomatic chronic obstructive pulmonary disease (COPD) having mild to moderate airflow limitation and are at high risk for future COPD exacerbations.
The study will be conducted in two parts. Part A will be a two week open label, single arm study in patients with COPD to obtain pharmacokinetic data and safety information of repeat dosing of danirixin in the population of interest. Approximately 10 subjects will be enrolled in Part A of the study. Progression to and dose selection for Part B will occur following review of the data collected in Part A. Part B will be a 52-week, randomized, double-blind (sponsor unblind), placebo-controlled on top of standard of care, parallel group study. Part B will evaluate several clinical efficacy assessments related to exacerbations and respiratory symptoms. Approximately 100 subjects will be enrolled with a target of 80 subjects completing 52 weeks of danirixin administration.

PK analysis of danirixin was conducted by non-compartmental methods. A Bayesian random effects model was performed adjusting for the trial as a random effect. A non-informative normal prior distribution was used. Point estimates and corresponding 90 percent credible intervals were constructed.
Number of Health Care Resource Utilization (HCRU) Defined COPD Exacerbations Per Year in Part B
Time frame: 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. The exacerbation rates along with the ratio (danirixin/placebo), were estimated and corresponding 95 percent credible intervals were produced using non-informative priors. 1 par. was excluded from the analysis.
Monthly Weighted Means of Exacerbations of Chronic Pulmonary Disease Tool-respiratory Symptoms (EXACT-RS) Total Score in Part B
Time frame: Up to Day 392 in Part B
EXACT-RS is a tool which consists of 11 items from the 14 item EXACT- patient reported outcomes (EXACT-PRO) instrument, intended to capture information related to the respiratory symptoms of COPD, i.e. breathlessness, cough, sputum production, chest congestion and chest tightness. The EXACT-RS has a scoring range of 0-40, higher scores indicate more severe symptoms. A par. had at least 10 days of diary data in any month to contribute a non-missing weighted mean AUC of daily values; otherwise the weighted mean for that month were considered missing. A mixed effects model in a Bayesian framework with repeated measures were performed on the EXACT-RS monthly weighted mean AUC data. The posterior mean and corresponding 95 percent credible interval were calculated. Only those participants with data available at the specified time points were analyzed (represented by n=X, X in the category titles).
