A Study to Learn About the Study Medicine Called PF-07275315 in People With Moderate to Severe Chronic Obstructive Pulmonary Disease
AN INTERVENTIONAL PHASE 2/3, RANDOMIZED, DOUBLE-BLIND, THIRD PARTY-UNBLINDED, PLACEBO-CONTROLLED, PARALLEL-GROUP STUDY TO INVESTIGATE EFFICACY AND SAFETY OF PF-07275315 IN ADULT PARTICIPANTS WITH MODERATE-TO-SEVERE CHRONIC OBSTRUCTIVE PULMONARY DISEASE (COPD)

Summary
The purpose of this clinical trial is to learn about the effects and safety of the study medicine PF-07275315 for the potential treatment of COPD. COPD is a condition that makes it difficult to breathe, which negatively impacts the quality of life and functioning of people who are affected. This study is seeking participants who: * Are 35 to 80 years old * Have had moderate-to-severe COPD for at least 12 months * Have a documented history of at least 2 moderate or severe exacerbations within the last 12 months * Have been continuously taking their regular maintenance treatment(s) for COPD over at least 6 months at a stable dose for 3 months All participants will receive PF-07275315 or a placebo. A placebo does not have any medicine in it but looks just like the medicine being studied. PF-07275315 or placebo will be given as multiple shots in the clinic over the course of 24 weeks for the Phase 2 part and 52 weeks for the Phase 3 part. We will compare the results of people receiving PF-07275315 to those of the people who do not. This will help us determine if PF-07275315 is safe and effective. Participants who will be involved in the Phase 2 part of the study for about 40 weeks. During this time, they will have 11 visits at the study clinic. Participants who will be involved in the Phase 3 part of the study for about 68 weeks. During this time, they will have 18 visits at the study clinic.
Eligibility
Inclusion Criteria4
- Diagnosis of chronic obstructive pulmonary disease (COPD) for at least 12 months (based on Global Initiative for Chronic Obstructive Lung Disease \[GOLD\] definition).
- Spirometry values (post-bronchodilator forced expiratory volume in 1 second \[FEV1\]/forced vital capacity \[FVC\] less than \[<\] 70 percent (%) and post-bronchodilator FEV1 % predicted <70%, but greater than equal to 30%).
- Continuous treatment with standard of care triple therapy of LABA + LAMA + ICS for ≥ 6 months prior to Screening Visit 1 and at a stable dose for ≥3 months
- Documented history of at least 2 moderate or severe ECOPD within the last 12 months prior to Screening.
Exclusion Criteria4
- Significant pulmonary disease other than COPD.
- Requirement for continuous chronic treatment with oxygen at >4.0 liters / minute by nasal cannula or equivalent.
- Hypoxemia with a resting SpO2 <88% while breathing ambient air (or on the participant's usual level of oxygen supplementation).
- Clinically significant cardiovascular disease, acute and/or severe left heart failure, or heart failure partial ejection fraction, and/or cor pulmonale.
