Outcome Measures

Primary Outcomes (2)

  • Incidence of treatment-emergent adverse events (TEAEs) during the study

    An adverse event (AE) is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product, which does not necessarily have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.

    From PA0012 Entry Visit until Safety Follow-Up (up to Week 212)

  • Incidence of treatment-emergent serious adverse events (SAEs) during the study

    A serious adverse event (SAE) is any untoward medical occurrence that at any dose: * Results in death * Is life-threatening * Requires in patient hospitalization or prolongation of existing hospitalization * Is a congenital anomaly or birth defect * Is an infection that requires treatment parenteral antibiotics * Other important medical events which based on medical or scientific judgement may jeopardize the patients, or may require medical or surgical intervention to prevent any of the above

    From PA0012 Entry Visit until Safety Follow-Up (up to Week 212)

Secondary Outcomes (28)

  • TEAEs leading to withdrawal from investigational medicinal product (IMP) during the study

    From PA0012 Entry Visit until Safety Follow-Up (up to Week 212)

  • American College of Rheumatology 20% improvement (ACR20) response at Week 24 in PA0012 using the Baseline of PA0010 or PA0011

    Baseline of PA0010 or PA0011, Week 24 in PA0012

  • American College of Rheumatology 20% improvement (ACR20) response at Week 52 in PA0012 using the Baseline of PA0010 or PA0011

    Baseline of PA0010 or PA0011, Week 52 in PA0012

  • American College of Rheumatology 20% improvement (ACR20) response at Week 140 in PA0012 using the Baseline of PA0010 or PA0011

    Baseline of PA0010 or PA0011, Week 140 in PA0012

  • American College of Rheumatology 50% improvement (ACR50) response at Week 24 in PA0012 using the Baseline of PA0010 or PA0011

    Baseline of PA0010 or PA0011, Week 24 in PA0012

  • +23 more secondary outcomes

Study Arms (1)

Bimekzumab dosage regimen

EXPERIMENTAL

Subjects participating in the study will receive assigned bimekizumab dosage regimen during the Treatment Period.

Drug: Bimekizumab

Eligibility Criteria

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

You may qualify if:

  • In the opinion of the Investigator, the subject is expected to benefit from participation in this Open-Label Extension study
  • Subject completed PA0010 \[NCT03895203\] or PA0011 \[NCT03896581\] without meeting any withdrawal criteria
  • Female subjects must be postmenopausal, permanently sterilized or willing to use a highly effective method of contraception

You may not qualify if:

  • Female subjects who plan to become pregnant during the study or within 20 weeks following the last dose of investigational medicinal product (IMP)
  • Subjects who meet any withdrawal criteria in PA0010 or PA0011. For any subject with an ongoing serious adverse event (SAE), or a history of serious infections (including hospitalizations) in the feeder studies, the Medical Monitor must be consulted prior to the subject's entry into PA0012, although the decision to enroll the subject remains with the Investigator
  • Subject has a positive or 2 indeterminate interferon gamma release assays (IGRAs) in one of the feeder studies, unless appropriately evaluated and treated

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.
