Outcome Measures
Primary Outcomes (1)
Percentage of Participants Achieving Hidradenitis Suppurativa Clinical Response (HiSCR) at Week 12
HiSCR was defined as at least a 50% reduction in abscess and inflammatory nodule (AN) count with no increase in abscess count and no increase in draining fistula count at Week 12 relative to Baseline. Data are presented for all participants and by baseline Hurley Stage (Stage 1: Abscess formation, single or multiple, without sinus tracts and scarring; Stage II: One or more widely separated recurrent abscesses with tract formation and scars. A participant with at least 1 anatomic region with Hurley Stage II disease and with no anatomic regions with Hurley Stage III disease was classified as Hurley Stage II; and Stage III: Multiple interconnected tracts and abscesses across the entire area, with diffuse or near diffuse involvement. A participant with at least 1 anatomic region with Hurley Stage III disease was classified as Hurley Stage III). Non-responder imputation (NRI): Participants with missing data were considered non-responders.
Baseline (Week 0) up to Week 12
Secondary Outcomes (3)
Percentage of Participants With Baseline Hurley Stage II Who Achieved Abscess and Inflammatory Nodule (AN) Count of 0, 1, or 2 at Week 12
Baseline (Week 0) up to Week 12
Percentage of Participants Achieving At Least 30% Reduction and At Least 1 Unit Reduction From Baseline in Patient's Global Assessment of Skin Pain (NRS30) - At Worst at Week 12 Among Participants With Baseline Skin Pain NRS ≥ 3
Baseline (Week 0) up to Week 12
Change From Baseline to Week 12 in Modified Sartorius Score
Baseline (Week 0) and Week 12
Study Arms (6)
Placebo
PLACEBO COMPARATORPlacebo for 12 weeks.
Adalimumab Every Week (EW)
EXPERIMENTALAdalimumab ew for 12 weeks (160 mg at Week 0; 80 mg at Week 2; and 40 mg ew from Week 4 to Week 12).
Placebo/Adalimumab Every Week (EW)
EXPERIMENTALParticipants randomized to receive placebo in Period 1 received adalimumab 160 mg at Week 12, 80 mg at Week 14, and 40 mg ew from Week 16 to Week 35 in Period 2 (up to 24 weeks).
Adalimumab Every Week (EW)/Placebo
EXPERIMENTALParticipants randomized to receive adalimumab ew in Period 1 were re-randomized to receive placebo ew from Week 12 to Week 35 in Period 2 (up to 24 weeks).
Adalimumab Every Week (EW)/ Adalimumab Every Other Week (EOW)
EXPERIMENTALParticipants randomized to receive adalimumab ew in Period 1 were re-randomized to receive adalimumab 40 mg eow from Week 12 to Week 35 in Period 2; placebo injections were administered eow from Week 13 to Week 35 (up to 24 weeks).
Adalimumab Every Week (EW)/Adalimumab Every Week (EW)
EXPERIMENTALParticipants randomized to receive adalimumab ew in Period 1 were re-randomized to receive 40 mg adalimumab ew from Week 12 to Week 35 in Period 2 (up to 24 weeks).
Interventions
Adalimumab pre-filled syringe, administered by subcutaneous injection
Placebo pre-filled syringe, administered by subcutaneous injection
Eligibility Criteria
You may qualify if:
- Adults must have a diagnosis of HS for at least 1 year prior to Baseline.
- HS lesions must be present in at least two distinct anatomical areas, one of which must be at least Hurley Stage II or Hurley Stage III.
- Subject must have stable HS for at least 60 days prior to Screening visit and at Baseline visit.
- Subject must have experienced an inadequate response to at least a 90-day treatment of oral antibiotics for treatment of HS.
- Subject must have a total AN count of greater than or equal to 3 at baseline.
You may not qualify if:
- Subject was previously treated with adalimumab or another anti-tumor necrosis factor (anti-TNF) therapy (e.g., infliximab or etanercept).
- Subject received any oral antibiotic treatment for HS within 28 days prior to Baseline.
- Subject received oral concomitant analgesics (including opioids) for HS-related pain within 14 days prior to Baseline visit.
- If entering the study on concomitant oral analgesics for non-HS related pain:
- Subject on opioid analgesics within 14 days prior to Baseline visit;
- Subject not on a stable dose of non-opioid oral analgesics for at least 14 days prior to the Baseline visit ("as needed" is not considered a stable dose).
