Primary Outcome Measures:
  • Percentage of Participants Achieving Hidradenitis Suppurativa Clinical Response (HiSCR) at Week 12 [ Time Frame: Baseline (Week 0) up to Week 12 ] [ Designated as safety issue: No ]
    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.


Secondary Outcome Measures:
  • Percentage of Participants With Baseline Hurley Stage II Who Achieved Abscess and Inflammatory Nodule (AN) Count of 0, 1, or 2 at Week 12 [ Time Frame: Baseline (Week 0) up to Week 12 ] [ Designated as safety issue: No ]
    The percentage of participants with AN counts lowered to 0, 1, or 2 at Week 12 among participants with Hurley Stage II at Baseline. NRI: Participants with missing data were considered non-responders.

  • 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 [ Time Frame: Baseline (Week 0) up to Week 12 ] [ Designated as safety issue: No ]
    The Patient's Global Assessment of Skin Pain Numeric Rating Scale (NRS) was used to assess the worst skin pain and the average skin pain due to HS. Ratings for the 2 items range from 0 (no skin pain) to 10 (skin pain as bad as you can imagine). The assessments were completed on a daily diary by participants before they went to bed and responded to the items based on a recall period of the "last 24 hours." The percentage of participants who achieved at least 30% reduction and at least 1 unit reduction from Baseline in the Patient's Global Assessment of Skin Pain (NRS30) - at worst at Week 12 among participants with Baseline NRS ≥ 3 are presented. Weekly averages of daily assessments were analyzed. NRI: Participants with missing data were considered non-responders.

  • Change From Baseline to Week 12 in Modified Sartorius Score [ Time Frame: Baseline (Week 0) and Week 12 ] [ Designated as safety issue: No ]
    The Sartorius Scale is used to quantify the severity of HS. Points are awarded for 12 body areas (left and right axillae, left and right sub/inframammary areas, intermammary area, left and right buttocks, left and right inguino-crural folds, perianal area, perineal area, and other): points were awarded for nodules (2 points for each); abscesses (4 points); fistulas (4 points); scars (1 point); other findings (1 point); and longest distance between two lesions (2-6 points, 0 if no lesions); and if lesions are separated by normal skin (yes-0 points; No-6 points). The total Sartorius score is the sum of the 12 regional scores. Last Observation Carried Forward (LOCF): The last completed evaluation from the previous visit within the particular period for efficacy measures was carried forward to impute missing data at later visits in the same period. Baseline efficacy evaluations were not carried forward.

Detailed Description:
The clinical trial identifier is PIONEER I. The purpose of this study is to evaluate the safety of adalimumab and to determine how well it works in the treatment of adults with moderate to severe HS. HS is a chronic skin disease that creates red, swollen, painful bumps which can break open to combine and form tunnels in the skin and scars. Sometimes these bumps can heal themselves quickly and sometimes they will become much worse and create sores that heal with multiple combined scars, or areas that do not heal. In this study, approximately 300 adults will be enrolled at treatment centers worldwide. Subject participation in this study will be up to 50 weeks. There will be a screening period, which will last from 7 to 30 days, and a study treatment period of up to 36 weeks. Study visits occur at Screening, Baseline, and Weeks 2, 4, 8, 12, 14, 16, 20, 24, 28, 32 and 36 (or sooner if subject leaves the study before Week 36). The study is divided into two treatment periods. The first period (Period A) will last 12 weeks and the second period (Period B) will last up to 24 weeks.

Exclusion Criteria:

  • 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.
