Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
The New York Heart Association’s four classes of how much heart failure limits physical activity.
Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.

Annualized rate of moderate or severe COPD Exacerbations
Moderate exacerbations are defined as clinically significant exacerbations that require treatment with oral/systemic corticosteroids and/or antibiotics. Severe exacerbations are defined as clinically significant exacerbations that require in-patient hospitalization (that is greater than or equal to \[\>=\] 24 hours) or result in death.
Time frame: Up to Week 78
Change from Baseline in St. George's respiratory questionnaire (SGRQ) total score
SGRQ total score will be measured using the SGRQ for COPD (SGRQ-C). The SGRQ-C is a 14-item participant questionnaire, designed to measure health impairment by addressing the frequency of respiratory symptoms (questions 1-7) and the participant's current state (questions 8-14). The total score will be calculated on 0-100 rating scale and scores expressed as a percentage of overall impairment. Higher scores indicate greater impairment of health
Time frame: Baseline (Day 1) and up to Week 52
Change from Baseline in pre-Bronchodilator Forced expiratory volume in 1 second (FEV1)
FEV1 is defined as the volume of air exhaled from the lungs in the first second of a forced expiration as measured by spirometry.
Time frame: Baseline (Day 1) and at Week 52
Annualized rate of COPD exacerbations requiring emergency department (ED) visit or hospitalization
Annualized rate of COPD exacerbations requiring ED visit or hospitalization (For pooled analysis across studies 300629 and 300631) will be assessed.
Time frame: Up to Week 78
Annualized rate of moderate/severe COPD exacerbations among participants with elevated screening blood eosinophil counts (BEC)
Annualized rate of moderate/severe COPD exacerbations among participants with elevated screening BEC (For pooled analysis across studies 300629 and 300631) will be assessed.
Time frame: Up to Week 78
Time to first moderate or severe COPD exacerbation
Time to first moderate or severe exacerbation (For pooled analysis across studies 300629 and 300631) will be assessed.
Time frame: Up to Week 78
