Background Randomized, controlled trials demonstrated efficacy and safety of apremilast for moderate-to-severe plaque psoriasis and psoriatic arthritis. Objective Assess long-term safety of oral ...apremilast in psoriasis patients. Methods Safety findings are reported for 0 to ≥156 weeks from the Efficacy and Safety Trial Evaluating the Effects of Apremilast in Psoriasis (ESTEEM) 1 and 2. Results The 0 to ≥156–week apremilast-exposure period included 1184 patients treated twice daily with apremilast 30 mg (1902.2 patient-years). During 0 to ≤52 weeks, the adverse events (AEs) that occurred in ≥5% of patients included diarrhea, nausea, upper respiratory tract infection, nasopharyngitis, tension headache, and headache. From 0 to ≥156 weeks, no new AEs (affecting ≥5% of the population) were reported. AEs, serious AEs, and study drug discontinuations caused by AEs did not increase with long-term exposure. During the 0 to ≥156–week period, the rates of major cardiac events (exposure-adjusted incidence rate EAIR 0.5/100 patient-years), malignancies (EAIR 1.2/100 patient-years), depression (EAIR 1.8/100 patient-years), or suicide attempts (EAIR 0.1/100 patient-years) did not increase in comparison with the rates found during the 0 to ≤52–week period. No serious opportunistic infections, reactivation of tuberculosis, or clinically meaningful effects on laboratory measurements were reported. Limitations This study had a high dropout rate (21% of patients ongoing >156 weeks); most were unrelated to safety concerns. Conclusions Apremilast demonstrated an acceptable safety profile and was generally well tolerated for ≥156 weeks.
Summary Background Apremilast, a small-molecule inhibitor of phosphodiesterase 4, works intracellularly to modulate proinflammatory and anti-inflammatory mediator production, and doses of 20 mg twice ...daily have shown efficacy in the treatment of moderate to severe plaque psoriasis in a 12-week phase 2 study. We assessed the clinical efficacy and safety of different doses of apremilast in the treatment of patients with moderate to severe plaque psoriasis. Methods In this phase 2b, multicentre, randomised, placebo-controlled, dose-ranging study, patients (aged ≥18 years) with moderate to severe psoriasis were randomly assigned (in a 1:1:1:1 ratio) to receive oral placebo or apremilast 10, 20, or 30 mg twice daily at 35 US and Canadian sites between Sept 24, 2008, and Oct 21, 2009. At week 16, patients in the placebo group were assigned apremilast 20 or 30 mg twice daily until week 24. Randomisation was generated with a permuted-block randomisation list via interactive voice response system. For the first 16 weeks, treatment assignment was concealed from both investigators and participants. During weeks 16–24, investigators and participants all knew that treatment was active, but the dose was concealed. The primary endpoint was the proportion of patients achieving at least 75% reduction from baseline psoriasis area and severity index (PASI-75) at week 16. Analyses were by intention to treat; missing values were imputed by last-observation-carried-forward. This trial is registered with ClinicalTrials.gov , number NCT00773734. Findings 89 patients were randomly assigned apremilast 10 mg, 87 apremilast 20 mg, and 88 apremilast 30 mg twice daily; 88 were assigned placebo. At week 16, PASI-75 was achieved in five patients (6%) assigned placebo, ten (11%) assigned apremilast 10 mg, 25 (29%) assigned 20 mg, and 36 (41%) assigned 30 mg. Apremilast 10 mg did not differ significantly from placebo in achievement of the endpoint (odds ratio 2·10; 95% CI 0·69–6·42); for both apremilast 20 mg (6·69; 2·43–18·5; p<0·0001) and apremilast 30 mg (11·5; 4·24–31·2; p<0·0001), the differences from placebo were significant. Most adverse events (96%) were mild or moderate; at least 5% of patients had nausea, upper respiratory tract infection, diarrhoea, nasopharyngitis, headache, arthralgia (placebo), gastroenteritis, or dyspepsia. Eight serious adverse events occurred (three each, placebo and apremilast 20 mg; two, apremilast 30 mg); none were judged to be related to apremilast. Apremilast had no apparent effect on the results of haematological, urinalysis, immunological or inflammation, serum chemistry, or electrocardiographic tests. Interpretation Apremilast, given orally at 20 or 30 mg twice daily, seems to be efficacious, safe, and tolerable for patients with moderate to severe plaque psoriasis.

Abstract Objectives Update on rheumatic diseases and their intersection with dermatology. Results This continuing medical education conference included more than 25 presentations and interactive ...sessions from leading experts in managing rheumatic diseases, comorbid conditions and related dermatologic diseases. Multiple areas were discussed, including: treating newly diagnosed rheumatoid arthritis; comparing Biologics in rheumatoid arthritis; examining changed approaches to treating SLE, psoriasis, psoriatic arthritis, ankylosing spondylitis, gout and vasculitis. Also visited were new understandings regarding chronic pain and osteoporosis. Conclusions Multiple presentations and interactive sessions from leading experts in the management of rheumatic diseases emphasized the interconnection between rheumatology and dermatology. Practical management approaches to both specialties and their sequelae were discussed.

Psoriasis is a lifelong, chronic disease that affects all ages. For some, psoriasis begins in childhood, and education of both pediatric patients and their parents is essential to successful and safe ...disease management. Systemic treatment of children is challenging as no evidence-based guidelines have been developed to date. When treating women with psoriasis, clinicians should also consider psychosocial effects. In patients of childbearing age, treatment options depend on the patients' choices regarding pregnancy.
Summary Background Dupilumab (an anti-interleukin-4-receptor-α monoclonal antibody) blocks signalling of interleukin 4 and interleukin 13, type 2/Th2 cytokines implicated in numerous allergic ...diseases ranging from asthma to atopic dermatitis. Previous 16-week monotherapy studies showed that dupilumab substantially improved signs and symptoms of moderate-to-severe atopic dermatitis with acceptable safety, validating the crucial role of interleukin 4 and interleukin 13 in atopic dermatitis pathogenesis. We aimed to evaluate the long-term efficacy and safety of dupilumab with medium-potency topical corticosteroids versus placebo with topical corticosteroids in adults with moderate-to-severe atopic dermatitis. Methods In this 1-year, randomised, double-blinded, placebo-controlled, phase 3 study (LIBERTY AD CHRONOS), adults with moderate-to-severe atopic dermatitis and inadequate response to topical corticosteroids were enrolled at 161 hospitals, clinics, and academic institutions in 14 countries in Europe, Asia-Pacific, and North America. Patients were randomly assigned (3:1:3) to subcutaneous dupilumab 300 mg once weekly (qw), dupilumab 300 mg every 2 weeks (q2w), or placebo via a central interactive voice/web response system, stratified by severity and global region. All three groups were given concomitant topical corticosteroids with or without topical calcineurin inhibitors where inadvisable for topical corticosteroids. Topical corticosteroids could be tapered, stopped, or restarted on the basis of disease activity. Coprimary endpoints were patients (%) achieving Investigator's Global Assessment (IGA) 0/1 and 2-point or higher improvement from baseline, and Eczema Area and Severity Index 75% improvement from baseline (EASI-75) at week 16. Week 16 efficacy and week 52 safety analyses included all randomised patients; week 52 efficacy included patients who completed treatment by US regulatory submission cutoff. This study is registered with ClinicalTrials.gov , NCT02260986. Findings Between Oct 3, 2014, and July 31, 2015, 740 patients were enrolled: 319 were randomly assigned to dupilumab qw plus topical corticosteroids, 106 to dupilumab q2w plus topical corticosteroids, and 315 to placebo plus topical corticosteroids. 623 (270, 89, and 264, respectively) were evaluable for week 52 efficacy. At week 16, more patients who received dupilumab plus topical corticosteroids achieved the coprimary endpoints of IGA 0/1 (39% 125 patients who received dupilumab plus topical corticosteroids qw and 39% 41 patients who received dupilumab q2w plus topical corticosteroids vs 12% 39 patients who received placebo plus topical corticosteroids; p<0·0001) and EASI-75 (64% 204 and 69% 73 vs 23% 73; p<0·0001). Week 52 results were similar. Adverse events were reported in 261 (83%) patients who received dupilumab qw plus topical corticosteroids, 97 (88%) patients who received dupilumab q2w, and 266 (84%) patients who received placebo, and serious adverse events in nine (3%), four (4%), and 16 (5%) patients, respectively. No significant dupilumab-induced laboratory abnormalities were noted. Injection-site reactions and conjunctivitis were more common in patients treated with dupilumab plus topical corticosteroids-treated patients than in patients treated with placebo plus topical corticosteroids. Interpretation Dupilumab added to standard topical corticosteroid treatment for 1 year improved atopic dermatitis signs and symptoms, with acceptable safety.

Clinical trials for systemic psoriasis therapy typically enroll healthy patients and exclude patients with cardiovascular disease, latent tuberculosis, liver disease, histories of malignancies, viral ...infections, children, and pregnant or breast-feeding women. Physicians often require guidance for optimum management of severe psoriasis in patients that have a combination of underlying disease states. To provide treatment recommendations for complex psoriasis scenarios, a consensus panel comprising 15 experts in psoriatic disease convened to review and discuss available evidence-based data and to arrive at a consensus for treatment options of difficult cases. An application of the Delphi Method was used to select case scenarios, provide medical treatment options, present the case study with existing medical evidence, and anonymously vote on treatment options. The top 10 treatment options were ranked and statistically analyzed to compare the differences between treatments. The final rankings and analysis provide guidance for practical, safe, and efficacious treatment options in a number of complex psoriasis scenarios.
