A Study to Learn About the Study Medicine Called PF-07275315 in People With Moderate to Severe Chronic Obstructive Pulmonary Disease
(COPD)
What this study is about
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.
View original scientific description
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.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- 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. Key
Exclusion criteria
- 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.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
