Outcome Measures

Primary Outcomes (1)

  • Percentage of participants with treatment-emergent adverse events (TEAEs) during the study

    An adverse event (AE) is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of investigational medicinal product (IMP), whether or not considered related to the IMP. NOTE: An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of IMP.

    From Baseline (Day 1) until end of Safety Follow-Up (up to Week 196)

Secondary Outcomes (7)

  • Percentage of participants with treatment-emergent serious adverse events (SAEs) during the study

    From Baseline (Day 1) until end of Safety Follow-Up (up to Week 196)

  • Percentage of participants with treatment-emergent adverse events (TEAEs) leading to withdrawal from the study

    From Baseline (Day 1) until end of Safety Follow-Up (up to Week 196)

  • Percentage of participants achieving clinical response as measured by Hidradenitis Suppurativa Clinical Response 50 (HiSCR50)

    Week 0, Week 16, Week 32, Week 48, Week 76, Week 92, Week 100, Week 116, Week 132, Week 148, Week 164, and Week 180

  • Percentage of participants achieving clinical response as measured by Hidradenitis Suppurativa Clinical Response 75 (HiSCR75)

    Week 0, Week 16, Week 32, Week 48, Week 76, Week 92, Week 100, Week 116, Week 132, Week 148, Week 164, and Week 180

  • Percentage of participants with Flare

    Week 0, Week 16, Week 32, Week 48, Week 76, Week 92, Week 100, Week 116, Week 132, Week 148, Week 164, and Week 180

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Study participant has completed the Maintenance Treatment Period through Week 48 in HS0003 (NCT04242446) or HS0004 (NCT04242498), was eligible to receive bimekizumab at the time of completing the feeder study, and did not meet any withdrawal criteria of the feeder study
  • Study participant is considered reliable and capable of adhering to the protocol (eg, able to understand and complete questionnaires), visit schedule, and medication intake according to the judgement of the Investigator
  • A female study participant is eligible to participate if she is not pregnant, not breastfeeding, and at least one of the following conditions applies:
  • Not a woman of childbearing potential (WOCBP) OR
  • A WOCBP who agrees to follow the contraceptive guidance during the open-label extension period and for at least 20 weeks after the final dose of investigational medicinal product (IMP)

You may not qualify if:

  • Female study participant who is breastfeeding, pregnant, or plans to become pregnant during the study or within 20 weeks following the final dose of investigational medicinal product (IMP)
  • Study participant has any medical or psychiatric condition that, in the opinion of the Investigator, could jeopardize or would compromise the participant's ability to participate in this study as determined by the Investigator based on protocol required assessments Note: For any study participant with an ongoing serious adverse event (SAE) from HS0003 (NCT04242446) or HS0004 (NCT04242498), or any current sign or symptom that may indicate a medically significant active infection (except for the common cold) or has had an infection requiring systemic antibiotics within 2 weeks of study entry or a history of serious infections in HS0003 or HS0004, the Medical Monitor must be consulted prior to the study participant's entry into HS0005, although the decision on whether to enroll the participant remains with the Investigator.
  • Study participant has a positive or indeterminate interferon-gamma release assay (IGRA) in a feeder study, unless appropriately evaluated and treated
  • Study participant has ongoing or planned use of prohibited hidradenitis suppurativa (HS) or non-HS treatment
  • Study participant plans to participate in another study of a medicinal product or device under investigation during this study

Data Sharing

IPD Sharing
Will share

Data from this trial may be requested by qualified researchers six months after product approval in the US and/or Europe, or global development is discontinued, and 18 months after trial completion. Investigators may request access to anonymized individual patient-level data and redacted trial documents which may include: analysis-ready datasets, study protocol, annotated case report form, statistical analysis plan, dataset specifications, and clinical study report. Prior to use of the data, proposals need to be approved by an independent review panel at www.Vivli.org and a signed data sharing agreement will need to be executed. All documents are available in English only, for a prespecified time, typically 12 months, on a password protected portal. This plan may change if the risk of re-identifying trial participants is determined to be too high after the trial is completed; in this case and to protect participants, individual patient-level data would not be made available.
