4. Patients are required to meet the following requirements at screening and baseline:

* Psoriasis involving 2%-20% BSA (excluding the scalp, palms, and soles);

5. Females of childbearing potential (FOCBP) must have a negative serum pregnancy test at Screening and a negative urine pregnancy test at Baseline. FOCBP must agree to take at least one reliable form of birth control, including oral/implantable/injectable/transdermal contraceptive, intrauterine device, bilateral tubal ligation/occlusion, partner's vasectomy, and barrier contraception (used correctly throughout sexual intercourse), from 4 weeks before the first dose of the IMP until 2 months after the last dose. If the subject is routinely abstinent, the subject may use this form of contraception, but should choose a reliable form of contraception as mentioned above if the subject is no longer abstinent. Male subjects will be required to have no plans to have children, no plans to donate sperm, and agree to use highly effective contraception. from the first dose of the investigational medicinal product until 4 months after the last dose.

Note: FOCBP are defined as female subjects who have experienced menarche, have not reached a postmenopausal state (amenorrhea for at least 12 consecutive months, with no clear cause other than menopause and confirmd by FSH), and have no surgical (i.e., bilateral oophorectomy and/or bilateral salpingectomy and/or hysterectomy) or investigator-determined causes of permanent infertility (e.g., mullerian agenesis, etc.).
6. Subjects were assessed by the investigator to be free of other medical conditions that would interfere with the assessment of safety and efficacy based on medical history, physical examination, routine blood, blood biochemistry, urine, and other laboratory tests.

Exclusion Criteria

1. Non-plaque psoriasis (e.g., guttate psoriasis, pustular psoriasis, erythrodermic psoriasis, and arthropathic psoriasis) or drug-induced psoriasis.

3. Prior use of etanercept within 4 weeks before the first dose of this study, or use of adalimumab and/or infliximab within 8 weeks before the first dose of this study, or prior use of another biologic within 12 weeks before the first dose of this study (or within 5 half-lives of the biologic at the time of the first dose of this study, whichever is longer).
4. Prior use of systemic drugs for psoriasis treatment or any other agents which may impact efficacy assessment of psoriasis, including but not limited to oral or intravenous glucocorticoids, retinoic acids, methotrexate, cyclosporine, and other systemic immunosuppressive agents or a class of drugs (including Chinese herbal formulas, herbs, proprietary Chinese medicines, etc.) containing Chinese medicinal ingredients within 4 weeks of the first dose of this study.
5. Prior use of topical agents for psoriasis treatment or any other agents which may impact efficacy assessment of psoriasis, including but not limited to topical glucocorticoids, vitamin D analogues, benvitimod and prescription emollients or emollients containing additives (e.g., ceramides, hyaluronic acid, urea, or filamentous proteolytic products) or antipruritic ingredients (e.g., menthol, polyhydroxyethanol, pramoxine, lidocaine, prilocaine, capsaicin, naltrexone, N-palmitoylethanolamine, etc.) or a class of drugs (including Chinese herbal formulas, herbs, proprietary Chinese medicines, etc.) containing Chinese medicinal ingredients for topical use (Note: for the treatment of diseases other than psoriasis, except in cases where the use of such medicines is deemed necessary in the medical judgment of the investigator and/or the specialist and would not interfere with the assessment of the study), etc. within 2 weeks.
6. Prior use of psoralen plus ultraviolet A (PUVA) or ultraviolet B (UVB) phototherapy within 4 weeks before the first dose of this study.
7. Prior use of ZORYVE® cream or foam; prior use of oral roflumilast or other phosphodiesterase-4 (PDE4) inhibitors (apremilast, etc.) within 4 weeks prior to the first dose of this study.
