A Pilot Study of Danirixin for Disease Progression in Chronic Obstructive Pulmonary Disease (COPD)

Phase 2

Terminated

• Conditions: Pulmonary Disease, Chronic Obstructive
• Interventions: Drug: Danirixin 35 mg tablets; Drug: Placebo; Device: Metered dose inhaler (MDI) sensor device; Drug: Rescue medication

• Registration Number: NCT03170232
• Lead Sponsor: GlaxoSmithKline

Brief Summary

This is a pilot study to investigate the effect of danirixin hydrobromide 35 milligram (mg) tablets on lung function and health related quality of life (HRQoL) in subjects with mild to moderate airflow obstruction and a demonstrated history of decline in forced expiratory volume in one second (FEV1). Specifically, this study aims to assess whether or not danirixin has the potential to impact disease progression in subjects with a COPD progression score indicating they are likely to decline based on 5 year data from a COPDGene study and support the conduct of a larger Phase III study for disease progression. Subjects will receive either placebo or danirixin 35 mg tablets (as hydrobromide hemihydrate salt) twice daily for 52 weeks (12months). Study subjects will continue with their standard of care inhaled medications (i.e. long acting bronchodilators with or without inhaled corticosteroids) while receiving study treatment. This study will be an ancillary study within the COPDGene study investigating the enrichment strategy for assessing disease progression. Potential subjects most likely to decline from the well established COPDGene cohort, will be based on data collected over the initial 5 year period. With the use of an enriched population, it is anticipated that one year of treatment will be sufficient to detect a trend in altering disease progression. Approximately 130 subjects will be screened to enroll 100 subjects in this study. The data from this study will provide useful information in determining whether to progress to a Phase III study to explore an indication for slowing disease progression.

Primary Outcome Measures

Name	Time	Method
Rate of Decline in Forced Expiratory Volume in One Second (FEV1)	Up to Week 52	FEV1 is a measure of lung function and is defined as the maximal amount of air that can be forcefully exhaled in one second. The effect of treatment on decline of post bronchodilator FEV1 recorded during the treatment period was analyzed using a repeated measures random coefficients model with covariates of treatment group, age, sex, smoking status, baseline FEV1, body mass index (BMI), study day and the treatment group by study day interaction. The adjusted mean and standard error for rate of decline in FEV1 have been presented.
Change From Baseline in St. George's Respiratory Questionnaire (SGRQ) Total Score (Derived From SGRQ-Chronic Obstructive Pulmonary Disease Specific Tool [SGRQ-C])	Baseline (Day 1 pre-dose), Weeks 12, 24 and 32	The SGRQ-C is a disease-specific questionnaire designed to measure the impact of respiratory disease and its treatment on a COPD participant's health-related quality of life (HRQoL). SGRQ-C total score was converted to SGRQ total score according to manual. The SGRQ Questionnaire is a well-established, self-completed tool, with 50 questions comprising three domains; Symptoms, Activity, and Impacts scores (each ranging from 0 to 100). SGRQ total score was calculated by summing weights from all positive items, divided by sum of weights for all items in SGRQ questionnaire and multiplying by 100. The SGRQ total score ranges from 0 to 100, with 0 implying the best possible health status and 100 implying worst possible health status. Baseline was defined as the score recorded prior to dosing on Day 1. Change from Baseline was calculated by subtracting Baseline value from the post dose visit value.

The CAT is an 8-item questionnaire suitable for completion by all participants diagnosed with COPD. Participants rated their experience on a 6-point scale, ranging from 0 (maximum impairment) to 5 (no impairment). A total CAT score was calculated by summing the non-missing scores of the eight items with a scoring range of 0-40. Higher scores indicated greater disease impact. Baseline was defined as the score recorded prior to dosing on Day 1. Change from Baseline was calculated by subtracting Baseline value from the post-dose visit value.

A rescue-free day was defined as a day where the total number of puffs were 0. The 4-weekly means were calculated and presented. Baseline was defined as the mean number of puffs of rescue medication per day from the latest (7 days before study treatment start date and date of Screening) to the day before study treatment start date.
