Percentage of Participants With Anti-bimekizumab Antibody (AbAb) Detection Prior to Investigational Medicinal Product (IMP) Administration
Anti-bimekizumab antibody (AbAb) detection prior to IMP administration. Anti-bimekizumab antibodies was measured using 3-tiered assay approach: screening assay, confirmatory assay, and titration assay. Antidrug antibody (ADAb) positive status: any sample that is positive screen and positive immunodepletion (regardless of availability of a titer value). ADAb negative status: any sample that is either negative screen, or positive screen and negative immunodepletion, and where the bimekizumab concentration is less than or equal to the drug tolerance limit of the validated ADAb assay. ADAb missing status: any sample that is either negative screen or positive screen and negative immunodepletion and where the bimekizumab concentration exceeds the validated ADAb assay drug tolerance limit.

Overall ADAb negative is defined as having all samples reported as negative, or has only one missing/inconclusive sample, following the 1st dose of IMP to SFU. Overall ADAb missing if the study participant has more than one missing ADAb sample for any reason and all other available ADAb samples are negative. The data was rounded to one decimal place.
Measured: From Baseline (Week 0, post-first dose) to Safety Follow-Up (Week 140)
Change From Baseline in Children's Dermatology Life Quality Index (CDLQI) Response at Week 16
The CDLQI is a questionnaire designed to measure the impact of skin diseases on the lives of children. The questionnaire consists of 10 questions that are based on the experiences of children with skin disease. The instrument asks participants about symptoms and feelings, leisure, school or holidays, personal relationships, sleep, and treatment. The questions relate to the impact of the skin disease on the child over the last week, (ie, over the last 7 days). The CDLQI total score ranges from 0 to 30 with higher scores indicating higher impact of skin disease on quality of life (Qol).
Measured: Baseline, Week 16

- Yes: Data from this trial may be requested by qualified researchers six months after product approval in the US and/or Europe, or global development is discontinued, and 18 months after trial completion. Investigators may request access to anonymized individual patient-level data and redacted trial documents which may include: analysis-ready datasets, study protocol, annotated case report form, statistical analysis plan, dataset specifications, and clinical study report. Prior to use of the data, proposals need to be approved by an independent review panel at www.Vivli.org and a signed data sharing agreement will need to be executed. All documents are available in English only, for a prespecified time, typically 12 months, on a password protected portal. This plan may change if the risk of re-identifying trial participants is determined to be too high after the trial is completed; in this case and to protect participants, individual patient-level data would not be made available.

- Individual participant dataSharing planned: Yes. Data from this trial may be requested by qualified researchers six months after product approval in the US and/or Europe, or global development is discontinued, and 18 months after trial completion. Investigators may request access to anonymized individual patient-level data and redacted trial documents which may include: analysis-ready datasets, study protocol, annotated case report form, statistical analysis plan, dataset specifications, and clinical study report. Prior to use of the data, proposals need to be approved by an independent review panel at www.Vivli.org and a signed data sharing agreement will need to be executed. All documents are available in English only, for a prespecified time, typically 12 months, on a password protected portal. This plan may change if the risk of re-identifying trial participants is determined to be too high after the trial is completed; in this case and to protect participants, individual patient-level data would not be made available.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing bimekizumab in people with Moderate to Severe Plaque Psoriasis, run by UCB Biopharma SRL at 11 sites in 4 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 11 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 3 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 11 sites in Poland, United States, Canada, Germany. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 18 May 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Plasma Concentration of Bimekizumab at Week 0 (time frame: Baseline (Week 0)). The study lists 13 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Aug 2026; AzTrials last refreshed its copy on 7 Nov 2026.
