Clinical Trial Summary

The KOrea COpd Subgroup Study team (KOCOSS) cohort is an ongoing, longitudinal, prospective, non-interventional and observational study within the Korean COPD patients. The prevalence of early COPD (mild to moderate COPD based by 2011 GOLD(the Global Initiative for Chronic Obstructive Lung Disease) guideline) is high in Korea. However, the patients with early COPD are not underdiagnosed due to mild symptom. The purpose of this study is to investigate early COPD characteristics and disease course and to form a guideline for early detection of COPD patients and prevention of progression to severe COPD.

Description:

This study is a multicentered, observational study of the patients with COPD who were enrolled in 45 tertiary and university-affiliated hospitals from December 2012 to now.

The initial evaluation for all patients includes pulmonary function tests (PFT), 6-min walk distance (6MWD), COPD Assessment Test (CAT), modified Medical Research Council (mMRC) dyspnea scale, and the COPD-specific version of St. George's Respiratory Questionnaire (SGRQ-C), exacerbations in the previous 12 months, smoking status, patient-reported education level, medications and comorbidities.

Pulmonary function tests (PFTs) are performed every 6 months and CAT, mMRC and SGRQ-C are evaluated every 6 months and 6 min walt test is performed every years during the whole period of study.

All of the data were reported using case-report forms (CRFs) which are completed by physicians or trained nurses, and the patients are to be evaluated at regular 6-month intervals after the initial examination.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of acute exacerbation	Number of events	5 years
Secondary	Pulmonary function tests	COPD severity will be assessed based on post-bronchodilator Forced expiratory volume in one second(FEV) and FEV1/FVC(Forced vital capacity). FEV1 to forced vital capacity (FVC) :Mild - FEV1/FVC<0.7, FEV1 =80% normal Moderate - FEV1/FVC<0.7, FEV1 50-79% normal; Severe - FEV1/FVC<0.70, FEV1 30-49% normal; Very Severe - FEV1/FVC<0.70, FEV1 <30% predicted. We will measure spirometry at screening and every 6 months.	5 years
Secondary	Modified Medical Research Council [mMRC] dyspnea scale	mMRC dyspnea scale is five-point scale with higher scores indicating more severe dyspnea. We will assess mMRC at screening and every 6 months.	5 years
Secondary	COPD Assessment Test (CAT)	The CAT score was also used for evaluation of dyspnea. It consists of 8 items, each scored from 0 to 5, with higher scores indicating a more severe symptom.We will measure CAT at screening and every 6 months.	5 years
Secondary	6-min walk distance (6MWD)	The 6MWD has been used as a simple tool to assess overall exercise tolerance in COPD patients. We will measure 6 min walk distance by ATS guideline at screening and every 6 months during the follow-up period	5 years
Secondary	the COPD-specific version of St. George's Respiratory Questionnaire (SGRQ-C)	to assess the health status from the patient's perspective .The SGRQ-C is a 14-item questionnaire that can be summarized as a total score, as well as by three component scores for symptoms, activities, and impacts. We will assess SGRQ at screening and every 6 months.	5 years
Secondary	Percentage of Participants with smoking history	we will assess smoking history at screening and every 6 months	5 years
Secondary	Percentage of Participants with Other Relevant Diseases	We will examine the relevant disease which is defined as respiratory diseases, cardiovascular diseases (ischaemic heart disease, heart failure, hypertension), and other diseases (osteoporosis, GERD(gastroesophageal reflux disease), hyperlipidemia, bronchiectasis, emphysema).	5 years
Secondary	COPD Treatment	COPD treatments are defined as inhaled therapies, oral therapies and other therapies administered during the enrollment and influenza vaccination and smoking cessation therapy	Through study completion, average 5 years
