This is a Study of Efficacy and Safety of Two Secukinumab Dose Regimens in Subjects With Moderate to Severe Hidradenitis Suppurativa (HS).
- Registration Number
- NCT03713619
- Lead Sponsor
- Novartis Pharmaceuticals
- Brief Summary
The purpose of this study is 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 will also assess the safety and tolerability of secukinumab.
- Detailed Description
This is a multicenter, randomized, double-blind, placebo-controlled, parallel group study with two secukinumab dose regimens in approximately 541 patients with moderate to severe HS. The study consists 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 will be an optional extension study. Adult males and females with moderate to severe HS will be included, with a diagnosis of HS greater than 1 year prior to baseline. Dosing will be once every 2 weeks, or once every 4 weeks via pre-filled syringe; periodic home-dosing is included.
The primary objective is to demonstrate the efficacy of secukinumab compared to placebo with respect to HISCR after 16 weeks of treatment; primary secondary objectives are to assess difference in proportion of patients with HS flares, and proportion of patients with clinical response in HS related skin pain after 16 weeks of treatment. Key safety data will be collected, along with Patient Reported Outcomes.

- Target Recruitment
- 545
- 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.
- Total fistulae count ≥ 20 at baseline.
- Any other active skin disease or condition that may interfere with assessment of HS.
- Active ongoing inflammatory diseases other than HS that require treatment with prohibited medications.
- Use or planned use of prohibited treatment. Washout periods detailed in the protocol have to be adhered to.
- History of hypersensitivity to any of the study drug constituents.
- History of lymphoproliferative disease or any known malignancy or history of malignancy of any organ system treated or untreated within the past 5 years, regardless of whether there is evidence of local recurrence or metastases (except for skin Bowen's disease, or basal cell carcinoma or actinic keratoses that have been treated with no evidence of recurrence in the past 12 weeks; carcinoma in situ of the cervix or non-invasive malignant colon polyps that have been removed).
- Pregnant or lactating women.

- 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 Change From Baseline in AN50 Count at Week 16 Baseline, 16 weeks The HS affected areas, e.g. right and left axillary (armpit), right and left gluteal ("buttock"), right and left inguinal-femoral (groin), perineal, pubic, sternal, right and left sub-mammary (breast) and others were assessed by the physician for abscesses, inflammatory nodules, draining fistulas, total fistulas, and other lesions.
Inflammatory lesions, including abscesses, nodules, draining fistulae, total fistulae and other lesions were counted. The analysis method for percentage change from baseline in abscesses and inflammatory nodules (AN) count at Week 16 was an ANCOVA model.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 Baseline, week 16 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.
