Delgocitinib Cream for the Treatment of Moderate to Severe Atopic Dermatitis During 8 Weeks in Adults, Adolescents, and Children

A Phase 1 Open-label, Multi-centre, Single-arm Trial to Evaluate the Safety and Pharmacokinetics (Including MUsT) of Twice Daily Topical Application of Delgocitinib Cream for 8 Weeks in Adults, Adolescents, and Children With Moderate to Severe Atopic Dermatitis

This is a multi-center, open-label trial to evaluate safety and pharmacokinetics of topical delgocitinib cream applied to pediatric subjects (2-17 years) and adult subjects (18 years and above) with atopic dermatitis.

A phase 1 open-label, multi-centre, single-arm trial to evaluate the safety and pharmacokinetics (including MUsT) of twice daily topical application of delgocitinib cream for 8 weeks in adults, adolescents, and children with moderate to severe atopic dermatitis

Key Inclusion criteria (Part 1: adults and adolescents; 12 years and above)

• Moderate to severe AD (Validated Investigator Global Assessment scale for Atopic Dermatitis [vIGA-AD] score of at least 3) at screening and at baseline

Key Inclusion criteria (Part 2: children; 2-11 years)

• Diagnosis of AD as defined by the Hanifin and Rajka (1980) criteria for AD
• Age 2-11 years at baseline
• History of AD for at least 3 months (children aged 2-5 years), and at least 12 months (children aged 6-11 years)
• AD involvement of ≥35% treatable BSA at screening and at baseline
• Moderate to severe AD (vIGA-AD score of at least 3) at screening and at baseline

Key Exclusion criteria (Part 1 and 2: subjects aged 2 years and above)

• Active dermatologic conditions that may interfere with the diagnosis of AD
• Use of tanning beds or phototherapy within 4 weeks prior to baseline
• Systemic treatment with immunosuppressive/modulating drugs or corticosteroids within 4 weeks prior to baseline or 3 or more bleach baths any week within 4 weeks prior to baseline
