Efficacy and Safety of Delgocitinib Cream in Adolescents 12-17 Years of Age With Moderate to Severe Chronic Hand Eczema

Prior treatment

• Concurrent skin diseases on the hands, e.g. tinea manuum.
• Systemic treatment with immunosuppressive drugs (e.g. methotrexate, cyclosporine, azathioprine), immunomodulating drugs, retinoids (e.g. alitretinoin), or corticosteroids within 28 days prior to baseline (steroid eyedrops and inhaled or intranasal steroids corresponding to up to 1 mg prednisolone for allergic conjunctivitis, asthma, or rhinitis are allowed).
• Use of tanning beds, phototherapy (e.g. ultraviolet B (UVB), ultraviolet A1 (UVA1), psoralen ultraviolet A (PUVA)), or bleach baths on the hands within 28 days prior to baseline.
• Previous or current treatment with JAK inhibitors (including delgocitinib/LEO 124249), systemic or topical.
• Cutaneously applied treatment with immunomodulators (e.g. PDE-4 inhibitors, pimecrolimus, tacrolimus) or TCS on the hands within 14 days prior to baseline.
• Use of systemic antibiotics or cutaneously applied antibiotics on the hands within 14 days prior to baseline.
• Other cutaneously applied therapy on the hands (except for the use of subject's own emollients) within 7 days prior to baseline.
• Cutaneously applied treatments in regions other than the hands, which could interfere with clinical trial evaluations or pose a safety concern within 7 days prior to baseline.

Other illness

• Clinically significant infection (e.g. impetiginised hand eczema) on the hands.
• Any disorder which is not stable and could:
  • Affect the safety of the subject throughout the trial.
  • Impede the subject's ability to complete the trial. Examples include but are not limited to cardiovascular, gastrointestinal, hepatic, renal, neurological, musculoskeletal, infectious, endocrine, metabolic, haematological, immunological, and psychiatric disorders, and major physical impairment.

• Age 12 to 17 years at screening and baseline.
• Diagnosis of CHE, defined as hand eczema that has persisted for more than 3 months or returned twice or more within the last 12 months.
• Disease severity graded as moderate to severe at screening and baseline according to IGA CHE (i.e. an IGA-CHE score of 3 or 4).
• Subjects who have a documented recent history of inadequate response to treatment with topical corticosteroids (TCS) (at any time within 1 year before the screening visit) or for whom TCS are documented to be otherwise medically inadvisable (e.g. due to important side effects or safety risks).
  • Inadequate response is defined as a history of failure to achieve and maintain a low disease activity state (comparable to an IGA-CHE score of ≤2) despite treatment with a daily regimen of TCS of class III-IV (potent to very potent) for Europe and Australia and class IV-I (medium potency to very/ultra-high potency) for Canada, applied for at least 28 days or for the maximum duration recommended by the product prescribing information, whichever is shorter.
  • Important side effects or safety risks are those that outweigh the potential treatment benefits and include intolerance to treatment, hypersensitivity reactions, and significant skin atrophy as assessed by the physician.
