• Diagnosis of chronic hand eczema defined as hand eczema, which has persisted for more than 3 months or returned twice or more within the last 12 months.
• Disease severity graded as mild to severe according to IGA (i.e., IGA ≥2).
• Recent history (within 1 year before the screening visit) of inadequate response to topical corticosteroid treatment or topical corticosteroid treatment being medically inadvisable.
• Diagnostic patch testing performed within 3 years prior to the screening visit.

Key Exclusion Criteria:

• Concurrent skin diseases on the hands e.g tinnea manuum.
• Active atopic dermatitis in regions other than the hands or psoriasis requiring medical treatment.
• Clinically significant infection (e.g., impetiginised hand eczema) on the hands.
• Systemic treatment with immunosuppressive drugs, immunomodulating drugs, retinoids, or corticosteroids within 4 weeks prior to baseline.
• Psoralen ultraviolet A (PUVA) or ultraviolet B (UVB) therapy on the hands within 4 weeks prior to baseline.
• Receipt of live attenuated vaccines 4 weeks prior to baseline.
• Cutaneously applied treatment with immunomodulators (e.g., phosphodiesterase-4 (PDE-4) inhibitors, pimecrolimus, tacrolimus) or topical corticosteroids on the hands within 2 weeks prior to baseline.
• Use of systemic antibiotics or cutaneously applied antibiotics on the hands within 2 weeks prior to baseline.
• Change in systemic antihistamine therapy within 2 weeks prior to baseline i.e., subjects must not start antihistamine treatment or change the current dosage regime within 2 weeks prior to baseline.
• Other cutaneously applied therapy on the hands (except for the use of subject's own emollients) within 1 week 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 1 week prior to baseline.
• Receipt of any marketed or investigational biologic agents within 6 months or 5 half-lives prior to baseline or until cells count returns to normal, whichever is longer.
• Clinically significant infection (systemic infection or serious skin infection requiring parenteral treatment) within 4 weeks prior to baseline.

• Positive hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (HBsAb), hepatitis B core antibody (HBcAb), or hepatitis C virus antibody (anti-HCV) serology at screening. Subjects with positive HBsAb may be randomised provided they are hepatitis B vaccinated and have negative HBsAg and HBcAb.
