Tinoridine hydrochloride Methods In the core SCULPTURE study, Psoriasis Area and Severity Index (PASI) 75 responders at Week 12 continued receiving subcutaneous secukinumab until Year 1. Thereafter, patients entered the extension phase and continued treatment as per the core trial. Treatment was double\blinded until the end Tinoridine hydrochloride of Year 3 and open\label from Year 4. Here, we focus on the 300?mg fixed\interval (every 4?weeks) treatment, the recommended per label dose. Efficacy data are primarily reported as observed, but multiple imputation (MI) and last observation carried forward (LOCF) techniques were also undertaken as supportive analyses. Results At Year 1, 168 patients entered the extension study and at the end of Year 5, 126 patients completed 300?mg (every 4?weeks) treatment. PASI 75/90/100 responses at Year 1 (88.9%, 68.5% and 43.8%, respectively) were sustained to Year 5 (88.5%, 66.4% and 41%). PASI responses were consistent regardless of the analysis undertaken (as observed, MI, or LOCF). The average improvement in mean PASI was approximately 90% through 5?years compared with core study baseline. DLQI (dermatology life quality index) 0/1 response also sustained through 5?years (72.7% at Year 1 and 65.5% at Year 5). The safety profile of secukinumab remained favourable, with no cumulative or unexpected safety concerns identified. Conclusion Secukinumab 300?mg treatment delivered high and sustained levels of skin clearance and improved quality of life through 5?years in patients with moderate\to\severe psoriasis. Favourable IL4R safety established in the secukinumab phase 2/3 Tinoridine hydrochloride programme was maintained through 5?years. Introduction Psoriasis is a chronic immune\mediated skin disease characterized by scaly erythematous plaques that potentially requires lifelong disease management. Secukinumab, a fully human monoclonal antibody that selectively neutralizes IL\17A, has been shown to have significant efficacy in the treatment of moderate\to\severe psoriasis and psoriatic arthritis, demonstrating high levels of efficacy with a favourable safety profile.1, 2, 3, 4, 5 The recommended (per label) dose of secukinumab is 300?mg subcutaneous. As psoriasis is a condition requiring long\term treatment, longitudinal data establishing the efficacy and safety of approved therapies are important for physicians and patients. Having previously demonstrated the sustained efficacy and favourable safety of secukinumab through 3?years of treatment in moderate\to\severe psoriasis patients;6 here, we present data through 5?years. Materials and methods Study design In the core SCULPTURE study, Psoriasis Area and Severity Index (PASI) 75 responders (75% improvement from baseline PASI score) at Tinoridine hydrochloride Week 12 were randomized to fixed\interval (FI; 150?mg or 300?mg), or retreatment\as\needed (RAN; 150?mg or 300?mg) regimens, as described previously in Mrowietz (%)118 (70.2)Race\Caucasian, (%)132 (78.6)Bodyweight, kg (Mean??SD)85.5??21.3BMI, kg/m2 (Mean??SD)28.7??6.2Time since first psoriasis diagnosis, years (Mean??SD)19.1??13.4PASI (Mean??SD)23.5??8.8BSA affected, % (Mean??SD)33.1??18.9DLQI (Mean??SD)13.1??7.4Psoriatic arthritis present, (%)33 (19.6)Previous systemic treatment, (%)Any120 (71.4)Biologic56 (33.3) Open in a separate window BMI, body mass index; BSA, body surface area; DLQI, Dermatology Life Quality Index; FI, fixed\interval; (IR)(IR)(IR)(IR)(IR)infectionsVulvovaginal candidiasis3 (1.8)3 (1.9)1 (0.7)0 (0.0)0 (0)Oral candidiasis0 (0.0)1 (0.6)0 (0.0)1 (0.7)0 (0.0)Neutropenia0 (0.0)0 (0.0)0 (0.0)0 (0.0)0 (0.0)MACE0 (0.0)0 (0.0)0 (0.0)1 (0.7)1 (0.7)b Inflammatory bowel diseaseCrohn’s disease0 (0.0)0 (0.0)0 (0.0)0 (0.0)0 (0.0)Ulcerative colitis0 (0.0)2 (1.2)c 1 (0.7)0 (0.0)0 (0.0)Malignant or unspecified tumours (excl.
