BACKGROUND: Secukinumab, a fully human anti-interleukin-17A monoclonal antibody, has shown superior efficacy to etanercept with similar safety in moderate to severe plaque psoriasis (FIXTURE study).
OBJECTIVE: We sought to directly compare efficacy and safety of secukinumab versus ustekinumab.
METHODS: In this 52-week, double-blind study (NCT02074982), 676 subjects were randomized 1:1 to subcutaneous injection of secukinumab 300 mg or ustekinumab per label. Primary end point was 90% or more improvement from baseline Psoriasis Area and Severity Index (PASI) score (PASI 90) at week 16.
RESULTS: Secukinumab (79.0%) was superior to ustekinumab (57.6%) as assessed by PASI 90 response at week 16 (P < .0001). The 100% improvement from baseline PASI score at week 16 was also significantly greater with secukinumab (44.3%) than ustekinumab (28.4%) (P < .0001). The 75% or more improvement from baseline PASI score at week 4 was superior for secukinumab (50.0%) versus ustekinumab (20.6%) (P < .0001). Percentage of subjects with the Dermatology Life Quality Index score 0/1 (week 16) was significantly higher with secukinumab (71.9%) than ustekinumab (57.4%) (P < .0001). The safety profile of secukinumab was comparable with ustekinumab and consistent with pivotal phase III secukinumab studies.
LIMITATIONS: The study was not placebo-controlled and of short-term duration.
CONCLUSIONS: Secukinumab is superior to ustekinumab in clearing skin of subjects with moderate to severe psoriasis and improving health-related quality of life with a comparable safety profile over 16 weeks.
Secukinumab is a fully human monoclonal antibody that selectively neutralizes interleukin 17A, a key cytokine involved in the development of psoriasis. Secukinumab has shown long-lasting efficacy and safety in the complete spectrum of psoriatic disease, including disease localized to nails, scalp, palms and soles, and joints (peripheral and axial arthritis). Given the chronic and relapsing nature of psoriasis, long-term data might help to fully characterize the efficacy and safety profile of secukinumab as well as its impact on quality of life.
Background: In a phase 3 clinical study, patients from Germany with moderate to severe psoriasis who were naïve to systemic treatment and received risankizumab had greater and more rapid disease improvements compared with those who received fumaric acid esters (FAEs).
Objective: To evaluate patient-reported outcomes (PROs) in patients treated with risankizumab compared with FAEs.
Methods: Adult patients were randomized 1:1 to receive either risankizumab 150 mg subcutaneous injections at weeks 0, 4 and 16 or FAEs (Fumaderm®) provided according to the prescribing label. PRO secondary endpoints assessed were Psoriasis Symptom Scale (PSS), Dermatology Life Quality Index (DLQI), 36-Item Short Form Health Survey, version 2 (SF-36v2), Patient Benefit Index (PBI), Hospital Anxiety and Depression Scale (HADS), Patient Global Assessment (PtGA) and European Quality of Life 5 Dimensions 5 Level (EQ-5D-5L). PROs were assessed at weeks 0, 16 and 24.
Results: Sixty patients each were randomized to receive risankizumab or FAEs. A significant PSS improvement was observed with risankizumab vs. FAEs at weeks 16 and 24 for total and psoriasis-associated redness, itching and burning scores (P < 0.001). DLQI scores were significantly lower (reflecting better health-related quality of life) with risankizumab vs. FAEs, with least squares (LS) mean differences of −7.4 and −7.6 at weeks 16 and 24, respectively (both P < 0.001). Patients randomized to risankizumab also had larger improvements in SF-36 Physical and Mental Component Summary scores, HADS anxiety and depression scores, PtGA, and EQ-5D-5L index and visual analogue scale scores (all P ≤ 0.002) at weeks 16 and 24 compared with FAEs. PBI was significantly higher, indicating greater benefit, with risankizumab vs. FAEs, with an LS mean difference of 1.1 and 1.3 at weeks 16 and 24, respectively (both P < 0.001).
Conclusions: Risankizumab provides significant benefits over FAEs in improving PROs across several dimensions in patients with moderate to severe psoriasis.
Background: Fumaric acid esters (FAEs; Fumaderm®) are the most frequently prescribed first-line systemic treatment for moderate-to-severe plaque psoriasis in Germany. Risankizumab (Skyrizi®) is a humanized IgG1 monoclonal antibody that specifically binds to the p19 subunit of interleukin 23. Objectives: To compare risankizumab treatment to FAEs in patients with psoriasis. Methods: This phase III randomized, active-controlled, open-label study with blinded assessment of efficacy was conducted in Germany. Patients were randomized (1 : 1) to subcutaneous risankizumab 150 mg (weeks 0, 4 and 16) or oral FAEs at increasing doses from 30 mg daily (week 0) up to 720 mg daily (weeks 8–24). Enrolled patients were adults naïve to and candidates for systemic therapy, with chronic moderate-to-severe plaque psoriasis. Phototherapy was not allowed within 14 days before or during the study. Results: Key efficacy endpoints were met at week 24 for risankizumab (n = 60) vs. FAEs (n = 60) (P < 0·001): achievement of a ≥ 90% improvement in Psoriasis Area and Severity Index (PASI; primary endpoint 83·3% vs. 10·0%), ≥ 100% improvement in PASI (50·0% vs. 5·0%), ≥ 75% improvement in PASI (98·3% vs. 33·3%), ≥ 50% improvement in PASI (100% vs. 53·3%) and a Static Physician’s Global Assessment of clear/almost clear (93·3% vs. 38·3%). The rates of gastrointestinal disorders, flushing, lymphopenia and headache were higher in the FAE group. One patient receiving risankizumab reported a serious infection (influenza, which required hospitalization). There were no malignancies, tuberculosis or opportunistic infections in either treatment arm. Conclusions: Risankizumab was found to be superior to FAEs, providing earlier and greater improvement in psoriasis outcomes that persisted with continued treatment, and more favourable safety results, which is consistent with the known safety profile. No new safety signals for risankizumab or FAEs were observed.
