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.
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).

Change in Homeostatic Model Assessment of Insulin Resistance (UNIT) (HOMA-IR) From Baseline to Week 12
Vital signs: summary statistics for change from baseline to Week 12 Healthy Range: 1.0 (0.5-1.4) Less than 1.0 means you are insulin-sensitive which is optimal. Above 1.9 indicates early insulin resistance. Above 2.9 indicates significant insulin resistance.
Time frame: baseline, Week 12
Change in Hemoglobin A1c (HbA1c) Test for Diabetes Score From Baseline to Week 12
Vital signs: summary statistics for change from baseline to week 12 For people without diabetes, the normal range for the hemoglobin A1c level is between 4% and 5.6%. Hemoglobin A1c levels between 5.7% and 6.4% mean you have a higher chance of getting diabetes. Levels of 6.5% or higher mean you have diabetes.
