Who can take part

AI summary

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for adults with hidradenitis suppurativa (HS) that is not severe but has a high risk of becoming severe. It compares adalimumab with standard care (doxycycline).

Age
Over 18 years, up to 64 years.
Sex
All sexes can join.
Disease stage
Non-severe HS with active lesions. IHS4 score < 11 and Hurley stage < 3. High risk of progressing to severe HS according to the risk algorithm.
Earlier treatment
No prior biological treatment for HS (for example Adalimumab, Anakinra, Ixekizumab, Secukinumab or Ustekinumab). Earlier whole-body HS treatment must have worn off. No current skin-applied HS treatment.
Biomarker or test result
Blood tests within set ranges. Negative for hepatitis B, hepatitis C, HIV, tuberculosis (IGRA) and ANA. Positive VZV IgG.

About the trial

What the trial wants to find out

The primary objective is to answer the following research question: In adults with non-severe hidradenitis suppurativa (HS) but a high risk of progression to severe disease, does treatment with adalimumab, compared with standard of care (SOC [doxycycline]), reduce the proportion of patients who progress to severe disease over a 104-week period?

Questions to ask the study team

  1. How often do I need to come in, and for how long each time?
  2. Are travel costs paid?
  3. Can I keep my own doctor?
  4. What happens if I want to stop?
