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.
Protocol ADRN-14 TIME-2 is a Phase 1b, randomized, placebo/vehicle-controlled, double-blinded, multi-center trial designed to assess the safety and efficacy of ShA9 topical application as a treatment for AD. This study will aim to enroll approximately 86 participants; participants must be 6 years of age or older and have AD. An individual participant's involvement in this study will take approximately 20 weeks to complete, including approximately 2 weeks of screening, 14 weeks of treatment, and 4 weeks of safety follow-up. An initial screening visit will be conducted to evaluate eligibility…
Inclusion Criteria: Each individual must meet all of the following criteria at Screening to be eligible for enrollment as a study participant: 1. Participant and/or parent/legal guardian must be able to understand and provide informed consent and assent (if applicable). 2. Male or female participant 6 years of age or older. 3. Meet ADRN Standard Diagnostic Criteria for active AD. Each individual must meet all of the following criteria at Baseline to be eligible for enrollment as a study participant: 4. Have at least 7 cm2 of lesional skin within the upper extremities, lower extremities,…
The ShA9 topical gel contains phosphate-buffered saline solution (PBS), Glycerol, and hydroxyethylcellulose containing lyophilized ShA9 bacteria. The ShA9 bacteria is derived from a healthy donor-derived (allogeneic) commensal Staph species. The gel is manufactured and packaged by University of California San Diego (UCSD). It is applied twice daily to all areas identified as actively lesional during the Baseline Visit, regardless of ongoing lesional status, until the Week 14 Visit. If new lesions arise during this time, these areas will also be treated, regardless of ongoing lesional status, until the Week 14 Visit.
Participants of all ages will apply hydrocortisone ointment 2.5% alongside the study product in sensitive body areas (e.g., face, neck, intertriginous regions) for the first two weeks of the trial. It is applied twice daily to all areas identified as actively lesional during the Baseline Visit, regardless of ongoing lesional status, until the Week 2 Visit. If new lesions arise during this time, these areas will also be treated, regardless of ongoing lesional status, until the Week 2 Visit.
Participants 12 years of age and older will apply clobetasol ointment 0.05% alongside the study product in non-sensitive body areas (e.g., arms, legs, torso) for the first two weeks of the trial. It will be applied twice daily to lesional skin and selected sampling areas from Baseline to Week 2. It is applied twice daily to all areas identified as actively lesional during the Baseline Visit, regardless of ongoing lesional status, until the Week 2 Visit. If new lesions arise during this time, these areas will also be treated, regardless of ongoing lesional status, until the Week 2 Visit.
Participants 12 years of age and older with a past intolerance to clobetasol or who become too sensitive to clobetasol in the initial two-week cotreatment period will apply fluocinonide ointment 0.05% as an alternative. In these cases, fluocinonide ointment 0.05% will be applied alongside the study product in non-sensitive body areas (e.g., arms, legs, torso) for the first two weeks of the trial. It is applied twice daily to all areas identified as actively lesional during the Baseline Visit, regardless of ongoing lesional status, until the Week 2 Visit. If new lesions arise during this time, these areas will also be treated, regardless of ongoing lesional status, until the Week 2 Visit.
The placebo (vehicle) topical gel contains phosphate-buffered saline solution (PBS), Glycerol, and hydroxyethylcellulose. The gel is manufactured and packaged by University of California San Diego (UCSD). It is applied twice daily to all areas identified as actively lesional during the Baseline Visit, regardless of ongoing lesional status, until the Week 14 Visit. If new lesions arise during this time, these areas will also be treated, regardless of ongoing lesional status, until the Week 14 Visit.
Participants 6 to 11 years of age will apply triamcinolone ointment 0.025% alongside the study product in non-sensitive body areas (e.g., arms, legs, torso) for the first two weeks of the trial. It is applied twice daily to all areas identified as actively lesional during the Baseline Visit, regardless of ongoing lesional status, until the Week 2 Visit. If new lesions arise during this time, these areas will also be treated, regardless of ongoing lesional status, until the Week 2 Visit.
