Psoriasis Clinical Trial
Biomarkers in Participants With Hidradenitis Suppurativa Receiving Guselkumab.
Summary
Hidradenitis Suppurativa (HS) is a severe, chronic debilitating disease with a variable and incomplete response to current treatments. Existing immunological studies have found dysregulation in the TH17:Treg axis with an increase in inflammatory mediators including TNFalpha, IL-17 IL-23 (amongst others) in lesional skin. Multiple cell typesincluding CD4+ cells, dendritic cells and macrophages infiltrate active lesions of HS and produce this major contribution from the Th17 axis.
One of the main barriers to the development of novel and effective treatments for HS is the lack of biomarker(s) of disease activity, as well as our incomplete understanding of the pathogenesis of this disease. Given the pronounced contribution of Th17 pathway (including interleukin-23) in the inflammation in HS, further investigation into the role of this axis in the pathogenicity of HS is essential. Guselkumab is a fully human interluekin-23 antagonist, FDA approved for the treatment of moderate to severe psoriasis in participants 18 years and over. Guselkumab is a novel potential therapy.
Full Description
Hidradenitis Suppurativa (HS) is a severe, chronic debilitating disease with a variable and incomplete response to current treatments.

Multiple cell typesincluding CD4+ cells, dendritic cells and macrophages infiltrate active lesions of HS and produce this major contribution from the Th17 axis.
One of the main barriers to the development of novel and effective treatments for HS is the lack of biomarker(s) of disease activity, as well as our incomplete understanding of the pathogenesis of this disease. Markers such as C- Reactive Protein, IL-6, soluble IL-2 receptor, S100A8/9, lipocalin-2 and the neutrophil/lymphocyte rati7 have been proposed as potential biomarkers but lack high specificity and correlation with disease severity. Given the pronounced contribution of Th17 pathway (including interleukin-23) in the inflammation in HS, further investigation into the role of this axis in the pathogenicity of HS is essential. Guselkumab is a fully human interluekin-23 antagonist, FDA approved for the treatment of moderate to severe psoriasis in participants 18 years and over. Guselkumab is a novel potential therapy.
Eligibility Criteria
Inclusion Criteria:
Have moderate to severe Hidradenitis Suppurativa (HS) for at least 1 year (365 days) prior to the baseline visit as determined by the investigator through participant interview and/or review of medical history
Have HS lesions present in at least 2 distinct anatomical areas
Had an inadequate response to an adequate course of appropriate oral antibiotics for treatment of HS (or demonstrated intolerance to, or had contraindications to oral antibiotic treatment of their HS
Have a total abscess and inflammatory nodule (AN) count greater than or equal to 3 at the screening and baseline visit
Must agree with daily use (throughout the study of one of the following over the counter treatments to body areas affected with HS lesions: either soap and water, a topical antiseptic was containing chlorhexidine gluconate, triclosan or benzoyl peroxide, or a dilute bleach bath.
Exclusion Criteria:
HIV Positive
Active Hepatitis B or C Infection
Pregnant or Breastfeeding
No concurrent use of any systemic antibiotics/retinoids/immunosuppressants (require washout period of 5 half lives)
Any medical, psychological or social condition that, in the opinion of the investigator would jeopardize the health or well being of the participant during any study procedures or integrity of the data
Has a draining fistula count greater than 20 at baseline visit Any other active skin disease (bacterial fungal or viral infection) that could have interfered with the assessment of HS
