NCT06977581

Brief Summary

The purpose of this clinical trial is to learn about the safety and effects of the study medicine (called PF-07275315) for the potential treatment of moderate-to-severe asthma. Asthma is a condition that makes it challenging to breathe, which negatively impacts the quality of life and functioning of people who are affected. This study is seeking participants who:

  • Are 18 to 70 years old
  • Have had moderate-to-severe asthma for at least 12 months that is not well controlled
  • Have been taking their regular maintenance treatment(s) for asthma over the last 12 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 12 weeks. We will compare the experiences 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 will be involved in this study for about 7.5 months. During this time, they will have 9 visits at the study clinic.

  • Clinically significant, treatment-related laboratory abnormalities

    Incidence of clinically significant changes in laboratory tests

    Baseline through Week 24

  • Clinically significant, treatment-related abnormalities in vital signs
