The Treatment of Hidradenitis Suppurativa Evaluation Study (THESEUS)
The THESEUS team includes people with hidradenitis suppurativa, dermatologists, GPs, surgeons and research experts.
Hidradenitis suppurativa is a long term, painful skin condition that affects approximately 1% of adults. It involves boils in areas such as the armpits and groins. The THESEUS study was developed to inform the design of future hidradenitis suppurativa trials and to help understand how hidradenitis suppurativa treatments are currently used. The study was developed with the support of the UK Dermatology Clinical Trials Network
Key information
What did THESEUS involve?
THESEUS investigated five treatments: two medicines (doxycycline, clindamycin & rifampicin), two types of surgery (deroofing and excision), and laser treatment. Further details about what each of these treatment choices entails can be found in the treatment decision grid.
The choice of treatment was decided by the participant and their doctor, and depended upon what treatment is available locally and severity of disease.
For further details, please see the patient information leaflet.
Who took part in the study?
Participants were
- 18 years of age or older
- Had a diagnosis of active hidradenitis suppurativa not controlled by current treatment.
