The purpose of this study is to learn if the study medicine (PF-08049820) is safe and effective for the treatment of atopic dermatitis (AD), also known as eczema, or atopic eczema. People with this condition may have severe itching and rashes on the skin. The study is seeking participants who: 1. Are 18 to 64 years of age; 2. Were confirmed to have AD at least 6 months ago; 3. Do not have a suitable prescribed medicine for AD; 4. Are considered by their doctors to have moderate to severe AD. The study has two stages (Stage 1 and Stage 2). In both stages, eligible participants will take either PF-08049820 or placebo as tablets by mouth daily for 12 weeks. A placebo does not have any medicine in it but looks just like the medicine being studied. Participants will visit the clinic on Day 1, Weeks 1, 2, 4, 6, 8 and 12. They will have a follow-up visit at Week 16. During this time, the participant's health and skin condition will be checked. They will have blood and urine tests. They will also have to answer questions about their health, skin condition, and how much their skin condition affects their lives. The experiences of participants receiving the study medicine will be compared to those receiving placebo. This will help to understand if PF-08049820 is safe and effective.
Phase 2 trials begin testing efficacy in a larger patient group (100–300). This is often where biotech binary events occur — positive Phase 2 data can significantly advance a company's pipeline narrative, while failures can be terminal for a program.
Currently recruiting: the trial is enrolling patients. A data readout is not expected until after enrollment closes and the follow-up period is complete.
Pfizer Inc (PFE) is the sponsoring company for this trial. BiotechSign currently grades this company C (52/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
