详细描述
This is an open-label, single-arm, multi-center phase III study. The purpose of this study is to evaluate the long-term safety and efficacy of AK101 injection in subjects with moderate-to-severe plaque psoriasis.

- •Subjects can continue to participate in this study based on assessment of investigator.
- •Subjects voluntarily participate in this study.
- •Subjects who are women of childbearing potential must be practicing an adequate, medically acceptable method of birth control during the treatment period and for at least 6 months after the last study drug administration.
- •Applicable for subjects newly enrolled:
- •Male or female subjects aged ≥ 18 years old.

排除标准
- •Applicable for subjects who have completed the previous Akeso trial (AK101-302) with AK101 injection:
- •Subjects who have severe AE or SAE occurred in an Akeso trial with AK101 injection.
- •Subjects who used prohibited drugs in an Akeso trial with AK101 injection.
- •Subjects performed poor compliance in an Akeso trial with AK101 injection, based on the assessment of investigator.
- •Subjects with any other disease, abnormal physical examination or abnormal laboratory examination leading to inapplicable for participating this study, based on the assessment of investigator.
- •Applicable for subjects newly enrolled:
- •Forms of psoriasis other than chronic plaque-type psoriasis.
- •History or evidence of active TB. Patients with evidence of latent tuberculosis may enter the trial after sufficient treatment had initiated and maintained according to protocol.

- •History of malignant tumour within 5 years before screening.
- •Any medical or psychiatric condition, laboratory, or ECG parameter which, in the opinion of the Investigator would place the subject at risk, interfere with participation or interpretation of the study.
