Outcome Measures

Primary Outcomes (1)

  • Percentage of Participants Achieving Clinical Response as Measured by Hidradenitis Suppurativa Clinical Response 50 (HiSCR50) at Week 16

    HiSCR50 was defined as at least a 50 percent (%) reduction from Baseline in the total abscess and inflammatory nodule (AN) count, with no increase from Baseline in abscess or draining tunnel count. Intermittent missing data are imputed using multiple imputation with Markov Chain Monte Carlo (MCMC) method followed by monotone regression for monotone missing data. Lesion counts were imputed and then dichotomized to obtain the response status. Participants who experienced an intercurrent event were treated as nonresponders following the intercurrent event. An intercurrent event was defined as receipt of systemic antibiotic rescue medication or discontinuation of study treatment due to an adverse event (AE) or lack of efficacy. Percentages of participants shown do not account for model effects using the logistic regression model.

    Week 16

Secondary Outcomes (8)

  • Percentage of Participants Achieving Clinical Response as Measured by Hidradenitis Suppurativa Clinical Response 75 (HiSCR75) at Week 16

  • Study participant must have moderate to severe HS defined as a total of ≥5 inflammatory lesions (ie, number of abscesses plus number of inflammatory nodules) at both the Screening and Baseline visits
  • Study participant must have had an inadequate response to a course of a systemic antibiotic for treatment of HS as assessed by the Investigator through study participant interview and review of medical history

You may not qualify if:

  • Draining tunnel count of \>20 at the Baseline Visit
  • Any other active skin disease or condition (eg, bacterial cellulitis, candida intertrigo, extensive condyloma) that may, in the opinion of the Investigator, interfere with the assessment of hidradenitis suppurativa (HS)

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.
