Brief Summary:
Hidradenitis suppurativa is a disease involving skin folds, causing swelling of the skin and surrounding tissues, pain, and foul-smelling discharges. Effective treatment options are lacking. Recently, clinical trials conducted in our lab found Brodalumab was an effective drug for this disease. Weekly dosing achieved superior therapeutic outcomes compared to a dosing given once in every other week. Brodalumab was safe in both regimens, but blood and tissue studies to better understand this response are still needed. By performing this small pilot study and collecting blood and tissue samples from participants treated with Brodalumab once weekly we would like to better characterize the molecular response to this treatment, identify blood and tissue markers reflecting disease severity, and better understand disease mechanisms.

Drug Information available for: Brodalumab

Arm Intervention/treatment
Experimental: Brodalumab treated moderate-to-severe HS patients
Weekly Brodalumab treatment 210mg/1.5ml, given subcutaneously for 12 weeks.
Drug: Brodalumab
Subcutaneously Brodalumab/Siliq, 210mg/1.5ml once a week
Other Name: Siliq

Primary Outcome Measures :
  1. Interleukin-17 receptor A (IL-17RA) saturation during brodalumab administration at week 12 vs baseline [ Time Frame: 12 weeks ]
    Percentage change in saturation

Secondary Outcome Measures :
  1. Change in levels of IL-17A, IL-17C, IL-17, CXCL1, and CXCL8 [ Time Frame: 12 weeks ]
    In Brodalumab treated participants at week 12 compared with baseline

  2. Correlate IL-17R saturation (measured by the frequencies of immune cells positive to IL-17RA by flow cytometry) with clinical measures, such as pain or the Hidradenitis Suppurativa Severity Score System (IHS4) [ Time Frame: 12 weeks ]
    In Brodalumab treated participants at week 12 compared with baseline
