COPD: Single Inhaler, Fixed-Dose Triple-Combination Therapy Reduced Exacerbations
MedicalResearch.com Interview from:
AstraZeneca Spokesperson
MedicalResearch.com: What is the background for this study? Would you briefly explain what is meant by COPD? How common is severe COPD?
Response: COPD, or chronic obstructive pulmonary disease, is a progressive disease associated mainly with tobacco smoking, air pollution or occupational exposure, which can cause obstruction of airflow in the lungs making it hard to breathe. In the United States, COPD is the fourth leading cause of death. Its prevalence in adults 18 years of age and older is 6.5 percent. An estimated 16 million people are currently diagnosed with COPD, and millions more are believed to have it but do not know it.
ETHOS is a randomized, double-blind, multi-center, parallel-group, 52-week trial to assess the efficacy and safety of PT010 in symptomatic patients with moderate to very severe COPD and a history of exacerbation(s) in the previous year. The trial compared two doses given twice daily of PT010 (320/14.4/9.6mcg and 160/14.4/9.6mcg) with glycopyrrolate/formoterol fumarate (14.4/9.6mcg) and PT009 (320/9.6mcg), all using AEROSPHERETM Delivery Technology in a pressurized metered-dose inhaler (pMDI). Outcomes in the ETHOS trial included, as a primary endpoint, the rate of moderate or severe exacerbations.
The Phase III ETHOS trial builds on the Phase III KRONOS data which together show PT010’s ability to reduce exacerbation risk in a broad range of patients with COPD, irrespective of whether they have had an exacerbation in the previous twelve months.
