A Study to Evaluate the Effect of Bimekizumab on Gene Expression Biomarkers in Study Participants With Moderate to Severe Plaque Psoriasis

Running, not enrolling · Phase 3

Conditions studied: Moderate to Severe Plaque Psoriasis, Psoriatic Arthritis

In brief

The purpose of this study is to evaluate the effect of bimekizumab on gene expression biomarkers at Week 48 in a subset of study participants with moderate to severe plaque psoriasis (PSO) and moderate to severe plaque PSO with concomitant active psoriatic arthritis (PsA) who have provided skin biopsies for reverse transcription-polymerase chain reaction (RT-PCR).

• Study participant has body weight <120 kg
• A female study participant is eligible to participate if they are not pregnant, not breastfeeding, and at least 1 of the following conditions applies:
• Not a woman of childbearing potential (WOCBP) OR A WOCBP who agrees to follow the contraceptive guidance during the Run In Treatment Period, the Randomized Treatment Extension Period, theTreatment Extension Period, the Escape Treatment Period, and for 17 weeks after the final dose of investigational medicinal product (IMP)

You may not qualify if…

• Cohort A and Cohort B
• Study participant has a form of PSO other than plaque type (eg, pustular, erythrodermic and guttate PSO, or drug induced PSO)
• Study participant has an active infection or history of infection(s) as follows:
• Any active systemic infection within 14 days prior to Baseline
• A serious infection, defined as requiring hospitalization or intravenous anti-infective(s) within 2 months prior to the Baseline Visit
• A history of opportunistic, recurrent, or chronic infections that, in the opinion of the investigator, might cause this study to be detrimental to the study participant
• At investigator's discretion, study participant with chronic (medically controlled) viral hepatitis B or C or human immunodeficiency virus (HIV) infection, or history of hepatitis B.
• Study participant has any of the following:
• Known active tuberculosis (TB) disease.
• History of active TB involving any organ system unless adequately treated
• High risk of acquiring TB infection
• Study participant has a verified diagnosis of inflammatory conditions other than PSO or PsA, including but not limited to rheumatoid arthritis (RA), sarcoidosis, inflammatory bowel diseases (IBD), or systemic lupus erythematosus. Note: Study participants with a diagnosis of IBD are allowed if they have no active symptomatic disease at Screening or Baseline
• Study participant has any active malignancy or history of malignancy within 5 years prior to the Screening Visit EXCEPT treated and considered cured cutaneous squamous or basal cell carcinoma, or in situ cervical cancer

• Study participant has a history of primary failure to any biologic (ie, no response within the first 12 weeks of treatment)
• Study participant has laboratory abnormalities at Screening

• Control Cohort
• Study participant has any systemic disease (eg, cardiovascular, neurological, renal, liver, metabolic, gastrointestinal, hematological, coagulation disorders, immunological) considered by the investigator to be uncontrolled, unstable, or likely to progress to a clinically significant degree during the course of the study
