Background Many studies have identified cardiovascular risk factors in patients with psoriasis. Some psoriasis therapies may increase cardiovascular disease (CVD) and others may decrease CVD. Objective We reviewed the literature to define the impact of common psoriasis therapies on cardiovascular measures and outcomes. Results Phototherapy has no major cardiovascular impact and may reduce levels of proinflammatory cytokines. Acitretin increases serum lipids and triglycerides, but has not been shown to increase cardiovascular risk. Cyclosporine A increases blood pressure, serum triglycerides, and total cholesterol. Methotrexate is associated with a decreased risk of CVD morbidity and mortality. Among the biologics, data for tumor necrosis factor inhibitors suggest an overall reduction in cardiovascular events. Most data on short-term ustekinumab use suggest no effect on major adverse cardiovascular events, however some authorities remain concerned. Nevertheless, ustekinumab use over a 4-year period shows a decrease in major adverse cardiovascular events when compared both with the general US population and with psoriatics in Great Britain. Limitations Most studies lack the power and randomization of large clinical trials and long-term follow-up periods. In addition, the increased risk of CVD associated with psoriasis itself is a confounding factor. Conclusion Some therapies for moderate to severe psoriasis, including methotrexate and tumor necrosis factor inhibitors, may reduce cardiovascular events in psoriatic patients. Ustekinumab appears to be neutral but there may be a long-term benefit. Appropriate patient counseling and selection and clinical follow-up are necessary to maximize safety with these agents. Further long-term study is necessary to quantify the benefits and risks associated with biologic therapies. © 2013 by the American Academy of Dermatology, Inc.

Biologics that neutralize specific cytokines have improved outcomes for several immune-mediated disorders but may also increase risks for particular side effects. This article postulates potential immunologic consequences of inhibiting components of the IL-23/T-helper cell 17 pathway-the target of next-generation biologics for treating psoriasis-based on clinical phenotypes of inherent or acquired deficiencies in this pathway. Generally, downstream deficiencies (e.g., IL-17A, IL-17F) are associated with fewer disorders compared with upstream deficiencies, suggesting that selectively blocking downstream targets may result in a narrower range of side effects. However, safety of these specific inhibitions must be established in long-term studies. © 2015 The Society for Investigative Dermatology.

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. Our results support continuing, longer-term studies. Funding Celgene Corporation.

BACKGROUND: Type 17 helper T cells have been suggested to play a pathological role in psoriasis. They secrete several proinflammatory cytokines, including interleukin-17A (also known as interleukin-17). We evaluated the safety and efficacy of ixekizumab (LY2439821), a humanized anti-interleukin-17 monoclonal antibody, for psoriasis treatment. METHODS: In our phase 2, double-blind, placebo-controlled trial, we randomly assigned 142 patients with chronic moderate-to-severe plaque psoriasis to receive subcutaneous injections of 10, 25, 75, or 150 mg of ixekizumab or placebo at 0, 2, 4, 8, 12, and 16 weeks. The primary end point was the proportion of patients with reduction in the psoriasis area-and-severity index (PASI) score by at least 75% at 12 weeks. Secondary end points included the proportion of patients with reduction in the PASI score by at least 90% or by 100%. RESULTS: At 12 weeks, the percentage of patients with a reduction in the PASI score by at least 75% was significantly greater with ixekizumab (except with the lowest, 10-mg dose) - 150 mg (82.1%), 75 mg (82.8%), and 25 mg (76.7%) - than with placebo (7.7%, P<0.001 for each comparison), as was the percentage of patients with a reduction in the PASI score by at least 90%: 150 mg (71.4%), 75 mg (58.6%), and 25 mg (50.0%) versus placebo (0%, P<0.001 for each comparison). Similarly, a 100% reduction in the PASI score was achieved in significantly more patients in the 150-mg group (39.3%) and the 75-mg group (37.9%) than in the placebo group (0%) (P<0.001 for both comparisons). Significant differences occurred at as early as 1 week and were sustained through 20 weeks. Adverse events occurred in 63% of patients in both the combined ixekizumab groups and in the placebo group. No serious adverse events or major cardiovascular events were observed. CONCLUSIONS: Use of a humanized anti-interleukin-17 monoclonal antibody, ixekizumab, improved the clinical symptoms of psoriasis. Further studies are needed to establish its long-term safety and efficacy in patients with psoriasis. (Funded by Eli Lilly; ClinicalTrials.gov number, NCT01107457.)

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. © 2015 American Academy of Dermatology, Inc.
