Danirixin Dose Ranging Study in Participants With Chronic Obstructive Pulmonary Disease (COPD)

Danirixin (DNX) is a selective CXC chemokine receptor (CXCR2) antagonist being developed as a potential anti-inflammatory agent for the treatment of COPD. This is a Phase 2, randomized, double-blind (Sponsor Open) study. The primary objective of the study is to evaluate the clinical activity and safety of danirixin compared with placebo in participants with COPD. Following baseline assessments collected over a 7 day period participants will be randomized (1:1:1:1:1:1) to receive one of five dose strengths of danirixin (5 milligram [mg], 10 mg, 25 mg, 35 mg and 50 mg) or placebo. Study treatment will be administered orally twice daily for 24 weeks. Participants will continue with their standard of care inhaled medications (i.e. long acting bronchodilators with or without inhaled corticosteroids) while receiving study treatment. Follow up will continue up to 28 days post last dose. Approximately 700 participants will be screened with a target of 540 participants completing 24 weeks of treatment and key study assessments.

Participants were completed each question by rating their experience on a 6 point scale ranging from 0 (maximum impairment) to 5 (no impairment) with a total scoring range of 0-40; higher scores indicate worse health status. A CAT score was calculated by summing the non-missing scores on the eight items. Individual items are scored from 0 to 5 with a total score range from 0 - 40, higher scores indicate greater disease impact. Day 1 was considered as Baseline. Change from Baseline was calculated by subtracting Baseline value from the specified time point value. Posterior mean change and standard deviation has been presented.
