Study to Explore the Effect of Secukinumab, Compared to Placebo, on Fat Tissue and Skin in Plaque Psoriasis Patients — ObePso-S  

Plaque Psoriasis Clinical Trial

Official title: A Randomized, Double-blind, Placebo-controlled, Parallel-group, Multicenter Study to Explore Changes in Subcutaneous Adipose Tissue and Modulation of Skin Inflammation After 12 Weeks of Treatment With Secukinumab, Compared to Placebo, and up to 52 Weeks of Treatment With Secukinumab in Adult Patients With Moderate to Severe Plaque Psoriasis

Status Completed

Clinical Trial Summary

This study provided a comparison of secukinumab to placebo with respect to skin inflammation as measured by skin exams in comparison to skin biopsies, adipose tissue and blood sample analyses.

Clinical Trial Description

This was a randomized, double-blind, placebo-controlled, multicenter design. Patients with moderate to severe plaque psoriasis received secukinumab 300 mg or placebo, with randomization stratified by body weight (< 90 kg, ≥ 90 kg). There were 5 periods to the study: Screening (1 to 4 weeks), Double-blind Treatment Period (12 weeks), Double-blind Induction Period (4 weeks), Open-label Treatment Period (36 weeks), and Follow-up Period (1 week).

During the Double-blind Treatment Period, all patients attended study visits at Baseline, Weeks 1, 2, 3, 4, 8, and 12, and all doses of study treatment were self-administered at the study site. Patients underwent lesional (LS) and non-lesional (NL) skin biopsies at Baseline and Week 12. Assessments for the primary efficacy variable were performed at Week 12 before patients received their Week 12 dose. During the Double-blind Induction Period, patients randomized to placebo were switched to secukinumab 300 mg for the remainder of the study.

K16 and skin histology/biomarkers were assessed from skin biopsies. The Psoriasis Assessment and Severity Index (PASI) and the Investigator's Global Assessment modified 2011 scale (IGA mod 2011) were performed at specified study visits. Safety was monitored by vital signs, weight, waist circumference, body mass index (BMI), and clinical laboratory tests (serum chemistry, hematology, highsensitivity C-reactive protein (hs-CRP), hemoglobin A1c (HbA1c), homeostatic assessment of insulin resistance (HOMA-IR), viral serology, serum and urine pregnancy). ;
