Primary Outcome Measures
NameTimeMethod
[Period 1] Percent change from baseline in abscess and inflammatory nodule (AN) count at 16 weeksWeek 16

AN count is calculated based on the sum of the abscesses and inflammatory nodules across 12 different anatomical areas

Secondary Outcome Measures
NameTimeMethod
[Period 1] Achieving HiSCR50 at Week 16Week 16

HiSCRO50 is defined as at least a 50% decrease in total abscess and inflammatory nodule (AN) count with no increase from baseline in abscess and/or draining fistula count

[Period 1] Achieving HiSCR75 at Week 16Week 16

HiSCR75 is defined as at least a 75% decreased in total abscess and inflammatory nodule (AN) count with no increase from baseline in abscess and/or draining fistula count

[Period 1] Absolute change from baseline in Dermatology Life Quality Index (DLQI) score at Week 16Week 16

The DLQI is a validated general dermatology questionnaire that consists of 10 items that assess subject health-related quality of life (daily activities, personal relationships, symptoms and feelings, leisure, work and school, and treatment). Each item uses a scale from 0 (not at all) to 3 (very much), with a total score being the sum of each question. The higher the total score the more a patient's life is affected by their skin condition.

[Period 1] Absolute change from baseline in Patient's Global Assessment of Hidradenitis Suppurativa (HS-PtGA) score at Week 16Week 16

The HS-PtGA is a single item measure that asks the individual to rate the overall impact of HS on their quality of life, capturing their comprehensive perception of disease severity and treatment response.

[Period 1] Absolute change from baseline in Skin Pain Numeric Rating Scale (NRS) at Week 16Week 16

The Skin Pain NRS is a single-item measure in which the participant rates the worst level of skin pain in the previous 24 hours on a scale from 0 (no pain) to 10 (worst pain imaginable).

[Period 1] Safety and tolerability of tibulizumabWeek 16

Assessed by the incidence of all treatment-emergent adverse events (TEAEs), as well as changes from baseline in vital signs, electrocardiogram (ECG) parameters, and laboratory results.
