E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to assess the safety and efficacy of risankizumab dose 1 and dose 2 versus placebo for the treatment of signs and symptoms of moderate to severe HS in adult subjects diagnosed for at least one year before the Baseline visit. |
|
E.2.2 | Secondary objectives of the trial |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
• Subjects must be ≥ 18 years old at Screening with a clinical diagnosis of moderate to severe HS (defined as a total AN count of ≥ 5 at Baseline, presence of HS lesions in at least 2 distinct anatomic areas, and draining fistula count of ≤ 20 at Baseline) for at least 1 year prior to Baseline, as determined by the investigator (i.e., through medical history, interview of subject). • Subjects must have a history of inadequate response or intolerance to an adequate trial of oral antibiotics for treatment of HS. • Prior exposure to anti-IL12/23/17 (overall, no more than 10% of the study population) • Prior exposure to anti-TNF (overall, no more than 15% of the study population) |
|
E.4 | Principal exclusion criteria |
No history of active skin disease other than HS that could interfere with the assessment of HS. No active TB or concurrent treatment for latent TB and no evidence of HBV, HCV or HIV. No documented active or suspected malignancy or history of any malignancy within the last 5 years. No history of organ transplantation. No exposure to other immunomodulatory biologic therapies, including anti-IL-1 within 3 months or 5 half-lives, whichever is longer, prior to Baseline. No previous treatment with any cell-depleting therapies including but not limited to anti-CD20 within 12 months prior to Baseline or until B cell count returns to normal level. |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint is the proportion of subjects achieving Hidradenitis Suppurativa Clinical Response (HiSCR) at Week 16. HiSCR is defined as at least a 50% reduction in the total inflammatory nodule [AN] count with no increase in abscess count and no increase in draining fistula count relative to Baseline. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
Proportion of subjects achieving at least 30% reduction and at least 1 unit reduction from Baseline in NRS30 in PGA Skin Pain at Week 8 among subjects with Baseline Numerical Rating Scale (NRS) ≥ 3. Proportion of subjects achieving NRS30 in PGA Skin Pain at Week 16 among subjects with Baseline NRS ≥ 3. Proportion of subjects who experience at least 25% increase in AN counts with a minimum increase of 2 relative to Baseline during Period A. Change from Baseline in DLQI at Week 16. Change from Baseline in HS-related swelling – assessed based on the HSSA at Week 16. Change from Baseline in HS-related odor – assessed based on the HSSA at Week 16. Change from Baseline in HS-related worst drainage – assessed based on the HSSA at Week 16. |
