SFY17915 Enrolling

Vaccine Response Trial for Atopic Dermatitis (36 Weeks)

Treatment: Injection Age: 18 Years

Recruiting adults (18 years of age) for this atopic dermatitis (AD) research study.

Individuals must have:

      • AD for 1 year or longer at baseline
      • documented history within 6 months prior to the screening visit, of either poor response or inadvisability of topical treatments
      • moderate to severe disease at baseline
      • involvement of 10% or more body surface area (BSA) at baseline
      • a body weight ≥40 kg and ≤150 kg

Participants will receive investigational treatment (active study drug) or placebo via subcutaneous injection, concurrently administered with 2 non-live vaccines.  Study treatment and study-related assessments will be provided at no cost.  Reimbursement for study-related expenses may be provided.

Study participation will last about 36 weeks and involve about 7 visits to the study centre.

Official Title

A Randomized, Double-blind, Placebo-controlled Phase 2 Study to Evaluate the Effect of Amlitelimab on Vaccine Antibody Responses in Adult Participants With Moderate to Severe Atopic Dermatitis ID




Study Description

  • Brief Summary:

    This is a Phase 2, multicenter, randomized, double-blind placebo controlled, 2-arm study to evaluate the effect of amlitelimab on vaccine antibody responses, and the safety of amlitelimab concurrently administered with non-live vaccines in adult participants with moderate-to-severe atopic dermatitis (AD). The purpose of this study is to compare the immune responses to concomitantly administered Boostrix (tetanus, diphtheria, and acellular pertussis [Tdap]) and Pneumovax 23 (PPSV) vaccines in adult participants with moderate-to-severe AD treated with amlitelimab versus placebo. The study will evaluate the percentage of participants achieving a positive anti-tetanus response at Week 16 (primary endpoint) and a positive anti-pneumococcal response at Week 16 (primary endpoint). Study details include: The study duration will be up to 36 weeks (for participants not entering the LTS17367 [RIVER-AD]). The screening period will be 2 to 4 weeks. The treatment duration will be up to 16 weeks. The post-treatment safety follow-up period will be16 weeks. The number of visits will be up to 7 (or 6 for those entering LTS17367 [RIVER-AD]).

Validated Investigator Global Assessment scale for atopic dermatitis (vIGA-AD) of 3 or 4 at baseline visit
Eczema area and severity index (EASI) score of 12 or higher at baseline
AD involvement of 10% or more of body surface area (BSA) at baseline

Participants for whom administration of the pneumococcal vaccine provided in this study is contraindicated or medically inadvisable, according to local label of the vaccine
Participants for whom administration of the tetanus, diphtheria, and pertussis vaccine provided in this study is contraindicated or medically inadvisable, according to local label of the vaccine
Having received any of the specified therapy within the specified timeframe(s) prior to the baseline visit
Known history of or suspected significant current immunosuppression
Any malignancies or history of malignancies prior to baseline (excluding in situ excised and cured cervical carcinoma, non-melanoma skin cancer excised and cured >3 years prior to baseline)
History of solid organ or stem cell transplant
Any active or chronic infection including helminthic infection requiring systemic treatment within 2 weeks prior baseline
