Study of Efficacy and Safety of Two Secukinumab Dose Regimens in Subjects With Moderate to Severe Hidradenitis Suppurativa (HS)

Phase 3

Completed

• Conditions: Hidradenitis Suppurativa
• Interventions: Drug: Secukinumab; Drug: Placebo

• Registration Number: NCT03713632
• Lead Sponsor: Novartis Pharmaceuticals

Brief Summary

The purpose of this study was to demonstrate superiority of secukinumab at Week 16, based on Hidradenitis Suppurativa Clinical Response (HiSCR) rates versus placebo, along with the maintenance of efficacy of secukinumab at Week 52 in subjects with moderate to severe HS. Moreover, this study assessed the safety and tolerability of secukinumab.

Detailed Description

This was a multicenter, randomized, double-blind, placebo-controlled, parallel group study with two secukinumab dose regimens in patients with moderate to severe HS. The study consisted of: screening (up to 4 weeks) treatment period 1 (16 weeks, active drug or placebo) and treatment period 2 (up to 1 year all patients on active drug); there was an optional extension study (NCT04179175). Adult males and females with moderate to severe HS were included, with a diagnosis of HS greater than 1 year prior to baseline. Dosing was once every 2 weeks, or once every 4 weeks via pre-filled syringe; periodic home-dosing is included.

In Treatment Period 1, participants were randomized to secukinumab Q2W, secukinumab Q4W, placebo Q2W or placebo Q4W in 1:1:0.5:0.5 ratio. In Treatment Period 2, at the Week 16 visit participants initially randomized to placebo were switched to one of the two active dose regimens (secukinumab Q2W or Q4W), while subjects randomized to secukinumab during Treatment Period 1 continued on the same dose.

• Target Recruitment: 545

Inclusion Criteria

• -Written informed consent must be obtained before any assessment is performed.
• Male and female patients ≥ 18 years of age.
• Diagnosis of HS ≥ 1 year prior to baseline.
• Patients with moderate to severe HS defined as:
• A total of at least 5 inflammatory lesions, i.e. abscesses and/or inflammatory nodules AND
• Inflammatory lesions should affect at least 2 distinct anatomic areas
• Patients agree to daily use of topical over-the-counter antiseptics on the areas affected by HS lesions while on study treatment.

Exclusion Criteria

• Total fistulae count ≥ 20 at baseline.
• Any other active skin disease or condition that may interfere with assessment of HS.

Arm && Interventions

Group	Intervention	Description
Secukinumab 1	Secukinumab	Secukinumab 300mg every 2 weeks
Secukinumab 2	Secukinumab	Secukinumab 300mg every 4 weeks
Placebo 1	Placebo	Placebo group to secukinumab 300mg every 2 weeks
Placebo 2	Placebo	Placebo group to secukinumab 300mg every 4 weeks

Primary Outcome Measures

Name	Time	Method
Percentage of Participants With Hidradenitis Suppurativa Clinical Response (HiSCR50)	16 weeks	HiSCR50 at Week 16 is defined as at least a 50% decrease in Abscess and inflammatory Nodule (AN) count compared to baseline with no increase in the number of abscesses and/or in the number of draining fistulas from baseline to Week 16. The baseline is defined as the last assessment (including unscheduled visits) obtained before/on the day of the first administration of the study treatment, or on the randomization date if there had been no drug administration.; This endpoint was analyzed by logistic regression.

Secondary Outcome Measures

Name	Time	Method
Percentage of Participants With Hidradenitis Suppurativa (HS) Flares	16 weeks	Percentage of participants who experience at least one flare over 16 weeks. A flare is defined as at least a 25% increase in abscesses and inflammatory nodules (AN) count with a minimum increase of 2 AN relative to baseline.; This endpoint was analyzed by logistic regression.
Percentage of Participants Achieving NRS30	16 weeks	Patients achieving Numerical Rating Scale score of 30 (NRS30) at week 16, defined as at least a 30% reduction and at least one unit reduction from baseline in the Patient's Global assessment of Skin Pain (where range 0 \[no skin pain\] to 10 \[worst skin pain\]).; This endpoint was analyzed by logistic regression.
Percentage Change From Baseline in AN Count	Baseline, 16 weeks	Percent change from baseline in abscesses and inflammatory nodules (AN) count. This endpoint was analyzed by analysis of covariance.
