Outcome Measures
Primary Outcome Measures
- Change from baseline in pre-bronchodilator FEV1 at Week 16 [up to Week 16]
FEV1 is the Forced expiratory volume in one second at study site
Secondary Outcome Measures
- Change from baseline in Chronic Obstructive Pulmonary Disease assessment tool (CAT) score [up to Week 16]
Chronic Obstructive Pulmonary Disease assessment tool (CAT) score ranges from 0 to 40, a higher score indicating a higher impact on health status.
- Change from baseline in St. George's Respiratory Questionnaire (SGRQ) total score [up to Week 16]
St. George's Respiratory Questionnaire (SGRQ) is a questionnaire designed to measure and quantify health-related health status in adult patients with chronic airflow limitation. A global score ranges from 0 to 100. Lower score indicates better quality of life.
- Percentage of participants with a decrease in SGRQ total score of ≥ 4 points from baseline to Week 16 [up to Week 16]
St. George's Respiratory Questionnaire (SGRQ) is a questionnaire designed to measure and quantify health-related health status in adult patients with chronic airflow limitation. A global score ranges from 0 to 100. Lower score indicates better quality of life.
- Annualized rate of moderate to severe COPD exacerbations in participants [up to Week 16]
Moderate or severe COPD exacerbation is defined by symptomatic worsening of COPD. Moderate：Use of systemic corticosteroids; and/or use of antibiotics; Severe：An inpatient hospitalization due to COPD
- Time to first Moderate or severe COPD exacerbation [up to Week 16]
Moderate or severe COPD exacerbation is defined by symptomatic worsening of COPD. Moderate：Use of systemic corticosteroids; and/or use of antibiotics; Severe：An inpatient hospitalization due to COPD
- Adverse events (AEs), measurement of vital signs，physical examination，electrocardiogram and laboratory tests at each visit. [Up to 24 Weeks]
The incidence and severity of treatment emergent adverse event (TEAE), including Serious Adverse Event (SAE), as well as clinical symptoms, and any abnormalities of vital signs, physical examinations，electrocardiogram，laboratory tests and, etc.
- 611 Concentration in Serum [Up to 24 Weeks]
The concentration of 611 in Serum
- Percentage of Participants with Anti-drug Antibodies and Neutralizing Antibodies [Up to 24 Weeks]
Immunogenicity assessment will be based on Anti-drug Antibodies (ADAs) response and development of Neutralizing Antibodies (NABs). Percentage is calculated based on the number of evaluable participants and was calculated by number of participants with treatment-emergent positive anti-drug antibodies / number of evaluable participants * 100%.
- Change in serum concentrations of PD variables [Up to 24 Weeks]
PD variables included Pulmonary and activation-regulated chemokine (PARC)，IgE，blood eosinophil counts and fibrinogen
