What the 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.

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.

Being studied: PF-07275315 dose 1; PF-07275315-dose 2; Placebo; PF-07275315-dose 3

  • 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
