A Study to Learn About the Study Medicine Called PF-07275315 in People With Moderate to Severe Chronic Obstructive Pulmonary Disease

Brief summary (registry, in English)

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.
