Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Proportion of participants who achieve Hidradenitis Suppurativa Clinical Response (HiSCR) [ Time Frame: Week 12 ]
    HiSCR is defined as at least a 50% reduction from baseline in the total abscess and inflammatory nodule count, with no increase from baseline in abscess or draining tunnel count.


Secondary Outcome Measures :
  1. Proportion of participants who achieve Hidradenitis Suppurativa Clinical Response 75 (HiSCR75) [ Time Frame: Week 12 ]
    HiSCR75 is defined as at least a 75% reduction from baseline in the total abscess and inflammatory nodule count, with no increase from baseline in abscess or draining tunnel count.

  2. Proportion of participants with flare [ Time Frame: 12 Weeks ]
    Participants who experience at least 1 flare over 12 weeks; flare is defined as at least a 25% increase in the total abscess and inflammatory nodule count with a minimum increase of 2 relative to baseline.

  3. Proportion of participants with a ≥ 3-point decrease in Skin Pain Numeric Rating Scale (NRS) score among participants with baseline Skin Pain NRS score ≥ 3 [ Time Frame: Week 12 ]
    Participants with a Skin Pain score of at least 3 at baseline and who experience at least a 3-point decrease in Skin Pain score at Week 12, relative to baseline. Skin Pain is an 11-point NRS, ranging from 0 (no skin pain) to 10 (worst skin pain).

  4. Proportion of participants who achieve Skin Pain NRS30 at Week 12 among participants with baseline Skin Pain NRS score ≥ 3. [ Time Frame: Week 12 ]
    Participants with a Skin Pain score of at least 3 at baseline and who achieve at Week 12 Skin Pain NRS30, defined as at least a 30% reduction and at least 1-unit reduction from baseline in the Skin Pain NRS.

  5. Proportion of participants with a ≥ 4-point increase from baseline in Functional Assessment of Chronic Illness Therapy - Fatigue (FACIT-F) score [ Time Frame: Week 12 ]
    Participants with a baseline FACIT-F score ≤ 48 and who experience at least a 4-point increase in FACIT-F score at Week 12, relative to baseline. The FACIT-F scale is a 13-item questionnaire that assesses self-reported fatigue and its impact upon daily activities and function over the past 7 days, with scores ranging from 0 (worst fatigue) to 52 (no fatigue).

  6. Mean change from baseline in Dermatology Life Quality Index (DLQI) score [ Time Frame: 54 weeks ]
    The DLQI is a skin disease specific questionnaire aimed at the evaluation of how symptoms and treatment affect participants' health-related quality of life (QoL). The DLQI total score ranges from 0 to 30, with higher scores indicating lower skin health related QoL.

  7. Mean change from baseline in abscess count [ Time Frame: 54 weeks ]
    Defined as mean change of abscess(es) count relative to baseline.

  8. Percentage change from baseline in abscess count [ Time Frame: 54 weeks ]
    Percent Change from baseline in number of abscess(es)

  9. Mean change from baseline in inflammatory nodule count [ Time Frame: 54 weeks ]
    Defined as mean change of inflammatory nodule count relative to baseline.

  10. Percentage change from baseline in inflammatory nodule count [ Time Frame: 54 weeks ]
    Defined as percent change from baseline in number of inflammatory nodule(s)

  11. Mean change from baseline in draining tunnel count [ Time Frame: 54 weeks ]
    Defined as mean change of draining tunnel count relative to baseline.

  12. Percentage change from baseline in draining tunnel count [ Time Frame: 54 weeks ]
    Defined as Percent change from baseline in number of draining tunnel(s)

  13. Extension Period: Proportion of participants who achieve HiSCR [ Time Frame: Week 24 ]
    HiSCR is defined as at least a 50% reduction from baseline in the total abscess and inflammatory nodule count, with no increase from baseline in abscess or draining tunnel count.

  14. Extension Period: Proportion of participants who achieve HiSCR75 [ Time Frame: Week 24 ]
    HiSCR75 is defined as at least a 75% reduction from baseline in the total abscess and inflammatory nodule count, with no increase from baseline in abscess or draining tunnel count.

  15. Extension Period: Proportion of participants with flare [ Time Frame: From Week 12 through Week 24 ]
    Participants who experience at least 1 flare over the period under assessment; flare is defined as at least a 25% increase in the total abscess and inflammatory nodule count with a minimum increase of 2 relative to baseline.

  16. Extension Period: Proportion of participants who achieved Skin Pain NRS30 among participants with baseline Skin Pain NRS score ≥ 3. [ Time Frame: Week 24 ]
    Skin Pain NRS30 defined as at least a 30% reduction and at least 1-unit reduction from baseline in the Skin Pain NRS.

  17. Extension Period: Proportion of participants who achieve HiSCR [ Time Frame: Week 54 ]
    HiSCR is defined as at least a 50% reduction from baseline in the total abscess and inflammatory nodule count, with no increase from baseline in abscess or draining tunnel count.

  18. Extension Period: Proportion of participants who achieve HiSCR75 [ Time Frame: Week 54 ]
    HiSCR75 is defined as at least a 75% reduction from baseline in the total abscess and inflammatory nodule count, with no increase from baseline in abscess or draining tunnel count.

  19. Extension Period: Proportion of participants with flare [ Time Frame: From Week 12 through Week 54 ]
    Participants who experience at least 1 flare over the period under assessment; flare is defined as at least a 25% increase in the total abscess and inflammatory nodule count with a minimum increase of 2 relative to baseline

  20. Extension Period: Proportion of participants who achieved Skin Pain NRS30 among participants with baseline Skin Pain NRS score ≥ 3. [ Time Frame: Week 54 ]
    Participants with a Skin Pain score of at least 3 at baseline and who achieve Skin Pain NRS30, defined as at least a 30% reduction and at least 1-unit reduction from baseline in the Skin Pain NRS.

  21. Extension Period: Proportion of participants who achieve maintenance of HiSCR or greater response at each visit [ Time Frame: From Week 12 through Week 54 ]
    Maintenance of response defined as participants who achieve HiSCR at Week 12 and maintain it or achieve greater response at each visit during the EXT period.

  22. Extension Period: Proportion of participants who achieve maintenance of HiSCR75 or greater response at each visit [ Time Frame: From Week 12 through Week 54 ]
    Maintenance of response defined as participants who achieve HiSCR75 at Week 12 and maintain it or achieve greater response at each visit during the EXT period.
