Brodalumab treatment resulted in significant clinical improvements in patients with moderate-to-severe psoriasis. (Funded by Amgen; AMAGINE-2 and AMAGINE-3 ClinicalTrials.gov numbers, NCT01708603 and NCT01708629.).

Efalizumab therapy resulted in significant improvements in plaque psoriasis in subjects with moderate-to-severe disease. Extending treatment from 12 to 24 weeks resulted in both maintenance and improvement of responses.

SummaryBackground The interleukin-17 cytokine family plays a central role in psoriasis pathogenesis. Objectives To evaluate the efficacy and safety of brodalumab, a human anti-interleukin-17 receptor antibody, in treating patients with moderate-to-severe plaque psoriasis. Methods In this phase III, double-blind, placebo-controlled study (NCT01708590; AMAGINE-1), adult patients in the U.S.A., Canada and Europe were randomized to brodalumab (140 or 210 mg) or placebo every 2 weeks (Q2W), with an additional dose at week 1, for a 12-week induction phase. At week 12, patients receiving brodalumab who achieved static Physician's Global Assessment 0 or 1 (sPGA success) were rerandomized to the placebo or induction dose. After week 16, patients with sPGA ≥ 3 were re-treated with the induction dose. After ≥ 12 weeks of retreatment, patients with sPGA 2 for ≥ 4 weeks or sPGA ≥ 3 were rescued with brodalumab 210 mg Q2W. At week 12, patients randomized to brodalumab with sPGA ≥ 2 or placebo received brodalumab 210 mg Q2W. Coprimary end points were the percentage of patients with ≥ 75% improvement in Psoriasis Area and Severity Index score (PASI 75) and sPGA success at week 12. Results There were 661 patients randomized: 220 placebo, 219 brodalumab 140 mg and 222 brodalumab 210 mg. At week 12, 60% (140 mg) and 83% (210 mg) vs. 3% (placebo) achieved PASI 75, and 54% (140 mg) and 76% (210 mg) vs. 1% (placebo) achieved sPGA success. The safety profile was considered acceptable. Conclusions Brodalumab therapy resulted in significant clinical benefit and an acceptable safety profile in patients with moderate-to-severe plaque psoriasis.

Summary Background Tralokinumab is a fully human monoclonal antibody that specifically neutralizes interleukin‐13, a key driver of atopic dermatitis (AD). Objectives To evaluate the efficacy and safety of tralokinumab in combination with topical corticosteroids (TCS) in patients with moderate‐to‐severe AD who were candidates for systemic therapy. Methods This was a double‐blind, placebo plus TCS controlled phase III trial. Patients were randomized 2 : 1 to subcutaneous tralokinumab 300 mg or placebo every 2 weeks (Q2W) with TCS as needed over 16 weeks. Patients who achieved an Investigator’s Global Assessment (IGA) score of 0/1 and/or 75% improvement in Eczema Area and Severity Index (EASI 75) at week 16 with tralokinumab were rerandomized 1 : 1 to tralokinumab Q2W or every 4 weeks (Q4W), with TCS as needed, for another 16 weeks. Results At week 16, more patients treated with tralokinumab than with placebo achieved IGA 0/1: 38·9% vs. 26·2% [difference (95% confidence interval): 12·4% (2·9–21·9); P = 0·015] and EASI 75: 56·0% vs. 35·7% [20·2% (9·8–30·6); P < 0·001]. Of the patients who were tralokinumab responders at week 16, 89·6% and 92·5% of those treated with tralokinumab Q2W and 77·6% and 90·8% treated with tralokinumab Q4W maintained an IGA 0/1 and EASI 75 response at week 32, respectively. Among patients who did not achieve IGA 0/1 and EASI 75 with tralokinumab Q2W at 16 weeks, 30·5% and 55·8% achieved these endpoints, respectively, at week 32. The overall incidence of adverse events was similar across treatment groups. Conclusions Tralokinumab 300 mg in combination with TCS as needed was effective and well tolerated in patients with moderate‐to‐severe AD.

Background: Ruxolitinib (RUX) cream demonstrated potent anti-inflammatory and antipruritic efficacy in a phase 2 study in adults with atopic dermatitis (AD).

BackgroundSecukinumab, a fully human monoclonal antibody that selectively neutralizes IL‐17A, has been shown to have significant efficacy and a favourable safety profile in the treatment of moderate‐to‐severe psoriasis and psoriatic arthritis.ObjectiveTo assess the efficacy and safety of secukinumab through 5 years of treatment in moderate‐to‐severe psoriasis.MethodsIn 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 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.ResultsAt 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.ConclusionSecukinumab 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 safety established in the secukinumab phase 2/3 programme was maintained through 5 years.
