Investigation of Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Clinical Efficacy of Oral Danirixin in Symptomatic COPD Subjects With Mild to Moderate Airflow Limitation at Risk for Exacerbations

Summary

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.
