简要总结
This is a randomized, double-blind, placebo-controlled multicenter clinical study to evaluate the efficacy, safety, and pharmacokinetics of SIM0278 in adult patients (18-75 years) with moderate to severe AD suitable for systemic therapy.
Approximately 184 subjects with moderate to severe AD are planned to be randomized in a 1: 1: 1: 1 ratio to SIM0278 low dose, SIM0278 medium dose, SIM0278 high dose, or placebo. Subjects were stratified at randomization by baseline disease severity (moderate [IGA = 3] VS severe [IGA = 4]).
The study consisted of 4 phases: screening, double-blind induction, open-label maintenance, and safety follow-up.

入选标准
- •Atopic dermatitis was diagnosed at screening (according to the American Academy of Dermatology consensus criteria for atopic dermatitis, 2014);
- •Use of a stable dose of emollients at least twice daily at sites of AD involvement starting at least 7 days prior to baseline;Alternatively, if the subject is using a prescribed emollients or moisturizers containing ceramide, urea, filaggrin degradation products, or hyaluronic acid prior to the Screening Visit, they may continue in the study but require a stable dose at least twice daily at the AD affected site starting at least 7 days prior to baseline;
- •Female and male subjects are willing to use protocol-required contraception from the Screening Visit until at least 90 days after the last dose and do not plan to become pregnant or donate sperm/eggs during this period.
排除标准
- •The subject was in an acute exacerbation of AD at baseline (e.g., the subject had a tendency to rapidly develop erythroderma or erythroderma in a short period of time, whichever was judged by the investigator);
- •Previous drug therapy with IL-2 or IL-2 analogues (including clinical studies);
- •Use of other immunomodulatory biologics within 3 months prior to baseline or within 5 drug half-lives, whichever is longer, including, but not limited to, anti-IL-23 (e.g., guselkumab), anti-IL-12/23 (e.g., ustekinumab), anti-IL-17 (e.g., secukinumab), or anti-IgE (e.g., omalizumab);
- •Use of cell depleting agents (e.g. rituximab) within 6 months prior to baseline;
- •Use of topical drugs for the treatment of AD or that may affect the assessment of the condition of AD within 2 weeks prior to baseline, including but not limited to TCS, TCI, phosphodiesterase-4 (PDE-4) inhibitors, Janus kinase (JAK) inhibitors, aromatic hydrocarbon receptor agonists, or Chinese herbal or herbal treatments, etc.;
- •≥ 2 bleaching baths per week within 2 weeks prior to baseline;
- •Systemic treatment (except glucocorticoid inhalers and nasal sprays) with glucocorticoids or other immunosuppressive/immunomodulatory drugs (e.g., cyclosporine, mycophenolate mofetil, azathioprine, methotrexate, or oral JAK inhibitors) within 8 weeks prior to baseline;
- •Use of systemic Chinese herbal medicine within 4 weeks prior to baseline ;
- •Phototherapy (narrow-band ultraviolet B (NBUVB), ultraviolet B (UVB), ultraviolet A (UVA), psoralen + ultraviolet A (PUVA)) tanning beds or any other phototherapy within 4 weeks prior to baseline;
- •Use of any investigational drug/therapy within 3 months or 5 drug half-lives (whichever is longer) prior to baseline;
