About this study

HS is a painful, chronic skin disease characterized by recurrent inflamed nodules and abscesses, which may rupture to form fistulas and subsequent scarring. This study is an open-label extension study available to subjects who participated in a prior adalimumab study who meet all the inclusion and none of the exclusion criteria.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Subjects who previously participated in a prior Phase 3 AbbVie hidradenitis suppurativa (HS) study (M11-313 or M11-810) and:
  • Completed the study; or
  • Experienced a loss of response (LOR); or
  • Experienced worsening or absence of improvement

Exclusion criteria

  • Prior treatment with any other anti-tumour necrosis factor (anti-TNF) therapy (e.g., infliximab, etanercept), or participation in an adalimumab trial other than a prior Phase 3 AbbVie HS study.

The total Sartorius score is the sum of the 12 regional scores. Higher scores indicate greater severity of HS. A negative change indicates decrease in severity. LOCF: The last completed evaluation from the previous visit was carried forward to impute missing data at later visits.
