Inclusion criteria
. Participants voluntarily agree to comply with all study procedures and scheduled follow-up assessments, and to cooperate with the collection of lesion photographs and other protocol-specified requirements;
. Diagnosis of plaque psoriasis, with or without PsA, established for at least 26 weeks prior to the first administration of study intervention. If previously diagnosed with psoriasis, participants must have a documented history of psoriasis for at least 26 weeks and must be confirmed by the investigator during screening to have plaque psoriasis;
. At screening and baseline, participants must be confirmed by the investigator to have stable moderate-to-severe plaque psoriasis, as defined by meeting all of the following four criteria:
Exclusion criteria
. Known allergy, hypersensitivity, or intolerance to biologics, study drugs, or their excipients.
. Non-plaque psoriasis (e.g., guttate, erythrodermic, pustular, or drug-induced psoriasis) at screening or randomization.
. Other skin lesions or systemic autoimmune diseases (e.g., systemic lupus erythematosus, Sjögren's syndrome, scleroderma) that may affect the safety and efficacy assessment of the study drug.
. Other skin lesions or systemic autoimmune diseases (e.g., systemic lupus erythematosus, Sjögren's syndrome, scleroderma) that may affect the safety and efficacy assessment of the study drug.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Proportion of participants achieving PASI 75 (≥75% improvement from baseline in PASI) at Week 16
. Severe, progressive, or poorly controlled renal, hepatic, cardiac, vascular, pulmonary, gastrointestinal, endocrine, neurological, hematologic, rheumatologic, psychiatric, or metabolic disorders; or current signs or symptoms related to these conditions.
. History of malignancy within 5 years before screening (except for adequately treated skin basal cell carcinoma, in situ skin cancer, or in situ cervical cancer with no recurrence for at least 12 weeks before the first dose).
. History of lymphoproliferative disorders (e.g., lymphoma), unexplained monoclonal gammopathy, or signs and symptoms suggestive of lymphoproliferative disorders (e.g., splenomegaly or severe lymphadenopathy).
. Any other condition deemed by the investigator as unsuitable for participation in the clinical study.
