Atopic Dermatitis Clinical Trials in Peoria, AZ

The purpose of this study is to learn about the safety and effects of 2 study medicines (PF-07275315 and PF-07264660) for the treatment of atopic dermatitis (AD). AD is a long- lasting itchy red rash, caused by a skin reaction. This study is seeking participants who: * are 18 years of age or more. * Were confirmed to have AD at least 6 months ago. * Are not having an effective treatment result from medicines that are applied on skin for AD. * Are considered by their doctors to have moderate to severe AD. In Stage 1 of the study, participants will receive either PF-07275315 or PF-07264660 or placebo. Stage 1 is complete. In Stage 2 of the study participants will receive either PF-07275315 or placebo. In Stage 3 of the study participants who have received anti-inflammatory proteins, will receive either PF-07275315 or placebo. A placebo does not have any medicine in it but looks just like the medicines being studied. PF-07275315 or PF-07264660 or placebo will be given as multiple shots in the clinic over the course of 12 weeks. Stage 1 participants will receive shots at the study clinic on Day 1, Week 1, Week 2, Week 4, Week 6, Week 8, Week 10 and Week 12. Stage 2 participants will receive shots at the study clinic on Day 1, Week 4, Week 8 and Week 12. Stage 3 participants will receive shots at the study clinic on Day 1, Week 4, Week 8, Week 12, Week 16, Week 20, Week 24 and Week 28. The experiences of people receiving PF-07275315 or PF-07264660 will be compared to people who do not. This will help determine if PF-07275315 and PF-07264660 are safe and effective. Participants in Stage 1 and 2 will be involved in this study for up to 40 weeks (10 months). During this time, Stage 1 participants will have 13 visits at the study clinic, and Stage 2 participants will have 9 visits at the study clinic. Participants in Stage 3 will be involved in this study for up to 52 weeks (13 months); and will have 13 visits at the study clinic. Read Less
