Primary Outcome Measures
NameTimeMethod
Mean Change From Baseline in Abscess and Inflammatory Nodule (AN) Count at Week 16Baseline; Week 16

Change from Baseline was calculated as the post-Baseline value minus the Baseline value. The mixed model repeated measure (MMRM) included the fixed effects of treatment group (placebo and INCB054707 15, 45, and 75 mg), stratification factors (disease severity \[Hurley Stage I, II, and III\] and geographical region \[North America and outside of North America\]), visit (Weeks 2, 4, 6, 8, 12, and 16), treatment by visit interaction, and covariates of Baseline measurement and Baseline measurement by visit interaction. The variance-covariance matrix of the within-participant errors in MMRM are modeled as unstructured.

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants Who Achieved a Hidradenitis Suppurativa Clinical Response (HiSCR) at Week 16Baseline; Week 16

HiSCR, the key secondary endpoint, was defined as at least a 50% decrease from Baseline in AN count with no increase in the number of abscesses or draining fistulas.

Percentage of Participants Who Achieved a HiSCR at Weeks 2 Through 12Baseline; Weeks 2, 4, 6, 8, and 12

HiSCR was defined as at least a 50% decrease from Baseline in AN count with no increase in the number of abscesses or draining fistulas.

Percentage of Participants Who Achieved AN50, AN75, AN90, and AN100 From Weeks 2 to 16Baseline; Weeks 2, 4, 6, 8, 12, and 16

AN50, AN75, AN90, and AN100 were defined as at least a 50%, 75%, 90%, and 100% decrease, respectively, from Baseline in AN count.

Mean Change From Baseline in AN Count at Weeks 2 to 12Baseline; Weeks 2, 4, 6, 8, and 12

Change from Baseline was calculated as the post-Baseline value minus the Baseline value. MMRM included the fixed effects of treatment group (placebo and INCB054707 15, 45, and 75 mg), stratification factors (disease severity \[Hurley Stage I, II, and III\] and geographical region \[North America and outside of North America\]), visit (Weeks 2, 4, 6, 8, 12, and 16), treatment by visit interaction, and covariates of Baseline measurement and Baseline measurement by visit interaction. The variance-covariance matrix of the within-participant errors in MMRM are modeled as unstructured.

Percentage of Participants Who Achieved HiSCR75 From Weeks 2 to 16Baseline; Weeks 2, 4, 6, 8, 12, and 16

HiSCR75 was defined as at least a 75% decrease from Baseline in AN count with no increase in the number of abscesses or draining fistulas.

Mean Change From Baseline in Draining Fistula Count From Weeks 2 to 16Baseline; Weeks 2, 4, 6, 8, 12, and 16

Change from Baseline was calculated as the post-Baseline value minus the Baseline value.

Mean Change From Baseline in Abscess, Inflammatory Nodule (IN), and Draining Fistula (DF) (ANF) Count From Weeks 2 to 16Baseline; Weeks 2, 4, 6, 8, 12, and 16

Change from Baseline was calculated as the post-Baseline value minus the Baseline value. MMRM included the fixed effects of treatment group (placebo and INCB054707 15, 45, and 75 mg), stratification factors (disease severity \[Hurley Stage I, II, and III\] and geographical region \[North America and outside of North America\]), visit (Weeks 2, 4, 6, 8, 12, and 16), treatment by visit interaction, and covariates of Baseline measurement and Baseline measurement by visit interaction. The variance-covariance matrix of the within-participant errors in MMRM are modeled as unstructured.

Mean Change From Baseline in the Severity of the Disease, as Assessed by the International Hidradenitis Suppurativa Severity Score System (IHS4) Score, From Weeks 2 to 16Baseline; Weeks 2, 4, 6, 8, 12, and 16

Change from Baseline was calculated as the post-Baseline value minus the Baseline value. The IHS4 is a composite, dynamic score and validated tool used to determine Hidradenitis Suppurativa severity. It employs a weighted scale using the number of inflammatory nodules, the number of abscesses, and the number of draining tunnels (fistulas or sinuses), with respective weight factors of 1, 2, and 4. Scores: mild=0-3; moderate=4-10; severe ≥11. MMRM included the fixed effects of treatment group (placebo and INCB054707 15, 45, and 75 mg), stratification factors (disease severity \[Hurley Stage I, II, and III\] and geographical region \[North America and outside of North America\]), visit (Weeks 2, 4, 6, 8, 12, and 16), treatment by visit interaction, and covariates of Baseline measurement and Baseline measurement by visit interaction. The variance-covariance matrix of the within-participant errors in MMRM are modeled as unstructured.

Percentage of Participants With a Total AN Count of 0 to 2 From Weeks 2 to 16Weeks 2, 4, 6, 8, 12, and 16

Total AN count was assessed throughout the study.

Number of Participants With Treatment-emergent Adverse Events (TEAEs)up to Week 16

An adverse event (AE) was defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug-related. An AE could have been any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of study treatment. A TEAE was defined as any AE either reported for the first time or the worsening of a pre-existing event after the first dose of study drug until the end of the safety follow-up.
