Targeted Investigation of Microbiome 2 Treat Atopic Dermatitis (TIME-2)
United States86 participantsStarted 2025-04-10
Plain-language summary
This is a Phase 1b, randomized, placebo/vehicle-controlled, double-blinded, multi-center trial. It is designed to assess the safety and efficacy of S. hominis A9 (ShA9) topical application as a treatment for atopic dermatitis (AD). The trial will enroll adults and pediatric participants with atopic dermatitis.
The primary safety objective of this study is to compare the safety profile of ShA9 to placebo (vehicle) over 14 weeks of application, which includes an initial two-week period of co-treatment with topical corticosteroids (TCS). The primary efficacy objective of this study is to assess the ability of ShA9, compared to placebo (vehicle), to prolong the period of atopic dermatitis control over 12 weeks after conclusion of an initial two-week period of co-treatment with TCS.

Inclusion criteria
. Participant and/or parent/legal guardian must be able to understand and provide informed consent and assent (if applicable).
. Male or female participant 6 years of age or older.
. Meet ADRN Standard Diagnostic Criteria for active AD.
. Have at least 7 cm2 of lesional skin within the upper extremities, lower extremities, and/or trunk. Lesions on the face, neck, hands, feet, and intertriginous areas do not count toward the required area, as samples may not be taken from these areas. The required area may be one contiguous area or may be comprised of multiple areas with a compliant total area.
. Have at least 3% body surface area of AD involvement as indicated by derived total area of involvement score during SCORAD assessment.
. Have an IGA score of two or greater.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
