- To evaluate the effect of AZD4831 as compared to placebo on the time to first COPD Composite Exacerbation (CompEx) event. [ Time Frame: From baseline to up to 24 weeks ]All participants randomised to either active or placebo arm.
- To assess the pharmacokinetics (PK) of AZD4831 in participants with moderate to severe COPD. [ Time Frame: Baseline and week 12 (or at early discontinuation visit due to rash) ]Measurement of Maximum Plasma Concentration (Cmax) at pre-randomisation (baseline visit) and week 12 (or at early discontinuation visit due to rash).
- To assess the PK of AZD4831 in participants with moderate to severe COPD [ Time Frame: Baseline and week 12 (or at early discontinuation visit due to rash) ]Measurement of Time to Reach Maximum Plasma Concentration (Tmax) at pre-randomisation (baseline visit) and week 12 (or at early discontinuation visit due to rash).
- To evaluate the effect of AZD4831 as compared to placebo on the time to first moderate or severe exacerbation. [ Time Frame: From baseline to up to week 24 ]All participants randomised to either active or placebo arms.
- To assess the effects of AZD4831 as compared to placebo on post-bronchodilator (BD) forced expiratory volume in the first second (FEV1) in participants with moderate to severe COPD. [ Time Frame: From baseline to week 12 ]All participants randomised to either active or placebo arms. Change in post-BD FEV1.
- To assess the effect of AZD4831 compared to placebo on respiratory symptoms in participants with moderate to severe COPD. [ Time Frame: From baseline to week 12 and week 24 ]All participants randomised to either active or placebo arms. Change from baseline in EXAcerbations of Chronic Pulmonary Disease Tool (EXACT) which is a 14-item ePRO instrument developed to assess the frequency, severity and duration of COPD exacerbations.
- To assess the effect of AZD4831 compared to placebo on respiratory symptoms in participants with moderate to severe COPD. [ Time Frame: From baseline to week 12 and week 24 ]All participants randomised to either active or placebo arms. Change from baseline in Breathlessness, Cough and Sputum Score (BCSS) with the 5-point Likert scale ranging from 0 (no symptoms) to 4 (severe symptoms).
- To assess the effect of AZD4831 compared to placebo on respiratory symptoms in participants with moderate to severe COPD. [ Time Frame: From baseline to week 12 and week 24 ]All participants randomised to either active or placebo arms. Change from baseline in cough Visual Analogue Scale (cough VAS) with the 100-point linear scale ranging from 0 (no cough) to 100 (worst cough).
- To assess the effect of AZD4831 compared to placebo in disease impact in participants with moderate to severe COPD. [ Time Frame: From baseline to Week 12 ]All participants randomised to either active or placebo arms. Change from baseline in total COPD Assessment Test (CAT) with the 5-point Likert scale ranging from 0 (no symptoms/no impact) to 5 (severe symptoms/impact).

Ages Eligible for Study: | 40 Years to 80 Years (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Provision of informed consent.
- Participants must be deemed as high risk of exacerbations as defined by: >= 1 moderate or severe exacerbation in the previous 24 months; or frequent productive cough; or post-bronchodilator (BD) forced expiratory volume in the first second (FEV1) < 50% predicted.
- Participants must be 40-80 years of age inclusive, at the time of signing informed consent form (ICF).
- Participants who have a confirmed primary diagnosis of moderate to severe COPD.
- Participants who are current or ex-smokers with a tobacco history of ≥ 10 pack-years.
-
Participants who have a documented stable regimen of triple therapy or dual therapy for
≥ 3 months prior to enrolment.
- Body mass index within the range 18 to 40 kg/m2 (inclusive).
Exclusion Criteria:
- Participants with a significant Coronavirus Disease 2019 (COVID-19) illness within 6 months of enrolment.
- As judged by the investigator, any evidence of any active medical or psychiatric condition or other reason (at SV1 [screening] and SV3 [pre-dose]) which in the investigator's opinion makes it undesirable for the participant to participate in the study.
- Current diagnosis of asthma or past diagnosis of asthma which persisted beyond the age of 25 years.
- Clinically important pulmonary disease other than COPD.
- Any other clinically relevant abnormal findings on physical examination, laboratory testing including haematology, coagulation, serum chemistry, or urinalysis; or chest CT scan at screening or randomisation, which in the opinion of the investigator or medical monitor may compromise the safety of the participant in the study or interfere with evaluation of the study intervention or reduce the participant's ability to participate in the study.
- History of a clinically significant infection (viral, bacterial, or fungal; defined as requiring systemic antibiotics, antiviral, or antifungal medication for > 7 days) within 4 weeks prior to SV3 (Day 1) (including unexplained diarrhoea) or clinical suspicion of infection at time of dosing.
