Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In Part A1, eligible participants were randomized at Baseline at a ratio of 4:1, stratified by weight and prior exposure to tumor necrosis factor antagonists to receive double-blind (DB) risankizumab 150 mg or placebo at Weeks 0 and 4. In Part A2, participants randomized at Baseline to receive DB placebo then received risankizumab 150 mg at Weeks 16 (Part A2) and at Week 28 and every 12 weeks up to 88 weeks (Part B); participants randomized to risankizumab 150 mg continued to receive risankizumab 150 mg at Week 16. Participants who received risankizumab in Part A and were nonresponders (sPGA \>2) at Week 28 received risankizumab 150 mg at Week 28 and every 12 weeks up to 88 weeks (Part B). In Part B, participants who received risankizumab in Part A and were responders (sPGA ≤2) at Week 28, were rerandomized at a ratio of 1:2 to receive DB risankizumab 150 mg or placebo at Week 28 and every 12 weeks up to 88 weeks (Part B). Starting at Week 32, rerandomized participants who reached relapse (defined as sPGA ≥3) were switched to risankizumab 150 mg every 12 weeks.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Male or female participants. Woman of childbearing potential must be ready and willing to use highly effective methods of birth control per ICH M3 (R2) that result in a low failure rate of less than 1 percent per year when used consistently and correctly.
* Age ≥18 years at screening
* Have a diagnosis of chronic plaque psoriasis (with or without psoriatic arthritis) at least 6 months before the first administration of study drug. Duration of diagnosis may be reported by the participant.
* Have stable moderate to severe chronic plaque psoriasis with or without psoriatic arthritis at both Screening and Baseline (Randomization); Have an involved body surface area (BSA) ≥ 10% and Have a Psoriasis Area and Severity Index (PASI) ≥ 12 and Have a static Physician Global Assessment (sPGA) score of ≥ 3.
* Must be a candidate for systemic therapy or phototherapy for psoriasis treatment, as assessed by the investigator
* Signed and dated written informed consent prior to admission to the study and performance of any study procedures in accordance with Good Clinical Practice (GCP) and local legislation

Exclusion Criteria

* Participants with nonplaque forms of psoriasis (including guttate, erythrodermic, or pustular); current drug-induced psoriasis (including a new onset of psoriasis or an exacerbation of psoriasis from beta blockers, calcium channel blockers, or lithium); active ongoing inflammatory diseases other than psoriasis and psoriatic arthritis that might confound trial evaluations according to the investigators judgment.
* Previous exposure to ABBV-066
* Currently enrolled in another investigational study or less than 30 days (from screening) since completing another investigational study
* Use of any restricted medication as noted or any drug considered likely to interfere with the safe conduct of the study.
* Major surgery performed within 12 weeks prior to randomization or planned within 12 months after screening (e.g., hip replacement, removal aneurysm, stomach ligation).
* Known chronic or relevant acute infections such as active tuberculosis, human immunodeficiency virus (HIV), or viral hepatitis
* Any documented active or suspected malignancy or history of malignancy within 5 years prior to screening, except appropriately treated basal cell carcinoma or squamous cell carcinoma of the skin or in situ carcinoma of uterine cervix
* Evidence of a current or previous disease (including chronic alcohol or drug abuse), medical condition other than psoriasis, surgical procedure (i.e., organ transplant), medical examination finding (including vital signs and electrocardiogram \[ECG\]), or laboratory value at the screening visit outside the reference range that in the opinion of the Investigator, is clinically significant and would make the study participant unable to adhere to the protocol or to complete the trial, compromise the safety of the patient, or compromise the quality of the data.
* History of allergy/hypersensitivity to a systemically administered biologic agent or its excipients
* Women who are pregnant, nursing, or who plan to become pregnant while in the trial
* Previous enrolment in this trial
