A Translational Study for Prediction of Biomarkers and Identification of Phenotype and Endotype of COPD and Pre-COPD Outcomes in Chinese Population

Prior treatment

• COPD exacerbation, within 2 weeks prior to enrollment or during screening period.
• History of partial or total lung resection (single lobe or segmentectomy is acceptable). Surgical or endoscopic (eg, valves) lung volume reduction within the 6 months prior to enrollment. Expected need for lung volume reduction surgery during the study.
• Malignancy, current or within the past 5 years, except for adequately treated non-invasive basal cell and squamous cell carcinoma of the skin and cervical carcinoma-in-situ treated with apparent success more than one year prior to enrollment. Suspected malignancy or undefined neoplasms.
• Participants receipt marketed or investigational biologics biologics within 3 months or 5 half-lives prior to visit 1, whichever is longer.

• Clinically important pulmonary disease.
• Unstable disorders.
• Terminal disease and/or organ failure or participants otherwise considered not appropriate for the study participation.

Lab values

• Clinically significant abnormal laboratory values available vital signs, ECG, or laboratory testing at the screening assessment that, which in the opinion of the investigator, could interfere with the objectives of the study or safety of the participant. -Current diagnosis of asthma.

Other

• The participant has an altered mental status at the time of informed consent.
• Female participants who are pregnant.

• Capable of giving signed ICF
• Able to perform acceptable lung function testing for FEV1 according to American Thoracic Society and European Respiratory Society 2019 acceptability criteria.
• Able and willing to comply with the requirements of the protocol including ability to read, write, be fluent in the translated language of all participants facing questionnaires used at center.
• Participants will be allowed to enroll into other non-intervention studies while taking part in this study.
