Primary Outcome Measures :
  1. Percentage of Participants Achieving Clinical Response as Measured by Hidradenitis Suppurativa Clinical Response (HiSCR) at Week 12 [ Time Frame: Week 12 ]
    HiSCR was defined as at least a 50 % reduction from Baseline in the total abscess and inflammatory nodule (AN) count, with no increase from Baseline in abscess or draining fistula count. Results were based on a Bayesian logistic regression model where the number of responders were assumed to follow a binomial distribution. Participants with missing data at Week 12 were considered as nonresponders in the analysis. Posterior mean response rates and 95% credible intervals in each group are presented.


Secondary Outcome Measures :
  1. Bimekizumab Plasma Concentration at Day 1 (Prior to First Dose) [ Time Frame: Day 1 (Prior to first dose) ]
    Plasma concentration of Bimekizumab was expressed in nanograms per milliliter (ng/mL). Values Below Limit of Quantification (BLQ) were replaced by value of Lower Limit of Quantification (LLOQ) divided by 2 (75 ng/mL) in calculations of Means and Coefficient of Variations (CVs).

  2. Bimekizumab Plasma Concentration at Week 2 [ Time Frame: Week 2 ]
    Plasma concentration of Bimekizumab was expressed in ng/mL. Values BLQ were replaced by value of LLOQ/2 (75 ng/mL) in calculations of Means and CVs.

  3. Bimekizumab Plasma Concentration at Week 4 [ Time Frame: Week 4 ]
    Plasma concentration of Bimekizumab was expressed in ng/mL. Values BLQ were replaced by value of LLOQ/2 (75 ng/mL) in calculations of Means and CVs.

  4. Bimekizumab Plasma Concentration at Week 8 [ Time Frame: Week 8 ]
    Plasma concentration of Bimekizumab was expressed in ng/mL. Values BLQ were replaced by value of LLOQ/2 (75 ng/mL) in calculations of Means and CVs.

  5. Bimekizumab Plasma Concentration at Week 12 [ Time Frame: Week 12 ]
    Plasma concentration of Bimekizumab was expressed in ng/mL. Values BLQ were replaced by value of LLOQ/2 (75 ng/mL) in calculations of Means and CVs.

  6. Bimekizumab Plasma Concentration at Week 30 [ Time Frame: Week 30 ]

  7. Percentage of Participants With at Least One Adverse Event During the Study [ Time Frame: From Screening to Safety Follow-Up (Week 30) ]
    An adverse event (AE) was any untoward medical occurrence in a patient or clinical investigation study participant administered a pharmaceutical product that did not necessarily have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.

  8. Percentage of Participants With at Least One Adverse Event Categorized by Maximum Severity During the Study [ Time Frame: From Screening to Safety Follow-Up (Week 30) ]
    An adverse event (AE) was any untoward medical occurrence in a patient or clinical investigation study participant administered a pharmaceutical product that did not necessarily have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. To record the intensity of an AE Investigator used the following criteria: Mild: the study participant was aware of sign or symptom (syndrome), but it did not interfere with his/her usual activities and/or was of no clinical consequence; Moderate: AE interfered with the usual activities of the study participant or it was of some clinical consequence; Severe: the study participant was unable to work normally or to carry out his/her usual activities, or the AE was of definite clinical consequence.

  9. Percentage of Participants With at Least One Serious Adverse Event During the Study [ Time Frame: From Screening to Safety Follow-Up (Week 30) ]
    A serious adverse event (SAE) was any untoward medical occurrence that at any dose: Resulted in death, was life-threatening, required in patient hospitalization or prolongation of existing hospitalisation, was a congenital anomaly or birth defect, was an infection that required treatment parenteral antibiotics, other important medical events which based on medical or scientific judgement may have jeopardised the patients, or may have required medical or surgical intervention to prevent any of the above.

  10. Percentage of Participants With at Least One Serious Adverse Event Categorized by Severity During the Study [ Time Frame: From Screening to Safety Follow-Up (Week 30) ]

To record the intensity of an AE Investigator used the following criteria: Mild: study participant was aware of sign or symptom (syndrome), but it did not interfere with his/her usual activities and/or was of no clinical consequence; Moderate: AE interfered with usual activities of study participant or it was of some clinical consequence; Severe: the study participant was unable to work normally or to carry out his/her usual activities, or the AE was of definite clinical consequence.
