简要总结

This 24-month study will assess the long-term safety and efficacy of liquid abrocitinib oral suspension with or without topical medications in children 2 years of age or older with moderate-to-severe atopic dermatitis. The study will enroll two groups: participants who have completed other abrocitinib studies and participants who have never participated in abrocitinib studies.

详细描述

Phase 3, open-label study to assess the long-term safety and efficacy of liquid abrocitinib oral suspension with or without topical medications in children ≥2 years of age with moderate-to-severe atopic dermatitis (AD). This study will enroll participants in two cohorts: an extension cohort of participants who previously completed prior abrocitinib studies, and a de novo cohort of participants (6 to <12 years of age) who have not participated in previous abrocitinib studies. Study duration will be up to 2 years (or commercial availability, whichever occurs earlier). The study will enroll a maximum of approximately 500 participants with moderate-to-severe Atopic Dermatitis from study sites globally (extension cohort will enroll up to 320 participants; de novo cohort will enroll approximately 180 participants). All participants will receive the study intervention abrocitinib oral suspension.

Female participants must not be pregnant or breastfeeding and, if the participant is of child-bearing potential, must use a highly effective form of contraception (i.e., abstinence) during the study intervention period and for at least 28 days after the last dose of study intervention.
  • •Inclusion Criteria for the De Novo Cohort:
  • •Children aged 6 to <12 years at the time of informed consent/assent.
  • •No contraception methods are required for male participants.
  • •Disease Characteristics:
  • •Participants who meet all of the following AD criteria:
  • •A documented diagnosis of chronic AD for at least 6 months prior to screening and confirmed at screening and baseline visits according to the Hanifin and Rajka criteria; and
  • •A diagnosis of moderate-to-severe AD at the baseline visit (must fulfill all of the following criteria: BSA ≥10%, vIGA ≥3, EASI ≥16, and WI-NRS ≥4); and
  • •Documented history (within 6 months of the screening visit) of inadequate response to treatment with topical medical therapy for AD (eg, TCS and TCI), for at least 4 weeks and are candidates for systemic therapy.

排除标准

  • •for the Extension Cohort:
  • •Medical Conditions:
  • •Any medical or psychiatric condition including any active suicidal ideation in the past year or suicidal behavior in the past 5 years or laboratory abnormality that may increase the risk of study participation or, in the investigator's judgment, make the participant inappropriate for the study.
  • •If the participant has SDQ total score ≥17, the investigator should exclude the child or refer them to a pediatric MHP to determine if it is safe to participate in the study. A copy or summary of the evaluation should be placed in the site source documents.
  • •Prior/Concomitant Therapy:
  • •Required use of any prohibited concomitant treatments outlined in Section 6.9.3 and Appendix 9 of study protocol.
  • •Required vaccination with live attenuated vaccines during study treatment and for 6 weeks after discontinuing study treatment.
  • •Diagnostic Assessments:
  • •Ongoing adverse event in the parent studies which in the opinion of the investigator, or sponsor, is an ongoing safety concern OR the participant is currently triggering safety monitoring criteria.
  • •Discontinued from treatment early in the parent studies OR triggered a discontinuation criterion at any point during the parent studies OR meets exclusion criteria from the parent studies which in the opinion of the investigator, or sponsor, is an ongoing safety concern.
  • •Exclusion Criteria for the De Novo Cohort
