- No plan of pregnancy and being willing to use effective contraceptive measures for patients (including partners) from signature of informed consent to 6 months after administration of investigational product, see Appendix 7 for the specific contraceptive measures.
- Exclusion criteria:
- Prior biologic therapy (Secukinumab or Ixekizumab) that directly targets il-17 monoclonal antibody or IL-17 receptor at any time;
- Use of a therapeutic biologic within 12 weeks prior to screening, or random administration of the drug during the elimination phase (5 half-lives), whichever is longer;
- Participated in any other clinical study with investigational drug intervention within 12 weeks prior to screening, or the investigational drug was in the elimination phase (5 half-lives) at the time of randomization, whichever is longer;
- Have received live vaccine within 12 weeks prior to screening, or plan to receive live vaccine within 12 weeks after administration of the last experimental drug;
- Any infection requiring hospitalization, antiviral or antibiotic treatment within 30 days prior to screening (such as pneumonia, cellulitis, bone and joint infection, etc., and the investigator determined that the patient had low immune function and participation in this study might lead to unacceptable risks);
- Received systemic treatment of Chinese herbal medicine for psoriasis within 30 days or external medication for psoriasis within 14 days prior to screening;
- Have received systemic treatment for psoriasis within 30 days prior to screening or were using a prohibited treatment at the time of screening.As UV exposure is one of the contraindication treatments, patients who do not wish to limit their UV exposure (e.g., sunbathing and/or using tanning devices) during the study period will be excluded;
- Non-chronic plaque psoriasis (e.g. Pustular psoriasis, erythrodermic psoriasis and intravenous psoriasis) at the time of screening;
- Drug psoriasis (new or aggravated psoriasis caused by beta blockers, calcium channel inhibitors or lithium) at the time of screening;

- Patients with serum creatinine above the upper limit of normal at screening time.Platelet \& LT during screening;100 x109/L, neutrophils \<1.5x109 /L, or hemoglobin \<85g/L, ALT or AST level increased ≥ 2 times the upper limit of normal value;
- Abnormal electrocardiogram during screening was considered clinically significant by the investigator, and participation in the study may bring unacceptable risks to the patients;
- At the time of screening, HBV DNA copy number was detected in persons who were positive for human immunodeficiency virus antibody (ANTI-HIV), hepatitis C virus antibody (anti-HCV), hepatitis B surface antigen (HBsAg) or HBcAb (upper limit of reference value of each hospital for quantitative test line);
- Known to suffer from moderate to severe allergic diseases or hypersensitivity reactions;
