What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: Up to Week 78
Secondary outcomes (5)
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.
Measured: 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.
Measured: 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.
Measured: 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.
Measured: 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.
Measured: Up to Week 78

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing GSK5784283 in people with Pulmonary Disease, Chronic Obstructive, run by GlaxoSmithKline at 7 sites in 2 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 5 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 7 sites in United States, Japan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact US GSK Clinical Trials Call Center (877-379-3718, GSKClinicalSupportHD@gsk.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Annualized rate of moderate or severe COPD Exacerbations (time frame: Up to Week 78). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Nov 2026.
