History of underlying medical diseases or problems including but not limited to the following: •\tSubject has been a previous recipient of a solid organ transplant that requires continuous immunosuppression. •\tRecent (within past 6 months) cerebrovascular accident or myocardial infarction •\tEvidence of a current or previous disease, medical condition (including chronic alcohol or drug abuse) other than psoriasis, surgical procedure (i.e., organ transplant), medical examination finding (including vital signs and ECG), or laboratory value at the screening visit outside the given range that, in the opinion of the investigator, is clinically significant and would make the study participant unreliable to adhere to the protocol or to complete the trial, compromise the safety of the patient, or compromise the quality of the data. •\tNo major surgery performed within 12 weeks prior to randomization or planned to be performed during the conduct of the trial (e.g., hip replacement, aneurysm removal, stomach ligation) as assessed by the Investigator. •\tHistory of suicidal ideation or attempts in the past 6 months."}
• {"criterion_text":"- 2. Presence of any concurrent illness, which in the opinion of the investigator, would place the patient at unnecessary safety risk during the trial or interfere with completion of the trial."}

• {"criterion_text":"- 4. Active skin disease other than psoriasis that could interfere with the assessment of psoriasis."}
• {"criterion_text":"- 5. Any active infections including HIV, viral hepatitis (hepatitis B, hepatitis C), and/ or active tuberculosis. Subjects with a positive QuantiFERON®-TB /PPD test result may participate in the study if further work up (according to local practice/guidelines) establishes conclusively that the subject has no evidence of active tuberculosis. If the presence of latent tuberculosis is confirmed, then tuberculosis prophylaxis treatment must have been initiated and maintained according to local country guidelines. The patient will not be eligible for randomization if latent tuberculosis is present and is untreated as per local guidelines."}
• {"criterion_text":"- 6. Treatment with topical medications for psoriasis in the past 2 weeks."}
• {"criterion_text":"- 7. For arm 2: Treatment with oral systemic classic medications (including phototherapy) for psoriasis in the past 4 weeks or 5 times of half-lives (whichever is longer)."}
• {"criterion_text":"- 8. Received a live vaccine within 6 weeks of start of RZB treatment."}
• {"criterion_text":"- 9. Participation in any other interventional clinical trial."}

Primary endpoints

• {"endpoint_text":"- The change in the number of epidermal and dermal CD8+CD103+ TRM cells at week 16 (compared to baseline lesional levels) in moderate to severe psoriasis patients treated with per label doses of risankizumab in early versus late treatment.","definition_or_measurement_approach":"Change measured as the difference in number of epidermal and dermal CD8+CD103+ TRM cells at week 16 compared to baseline lesional levels in patients treated with per-label risankizumab (early vs late treatment)."}

Secondary endpoints
