About

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.

Full 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.

• 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
