Asthma is one of the most common chronic diseases of childhood. Allergen sensitization and high frequencies of comorbid allergic diseases are characteristic of severe asthma in children. Omalizumab, ...an anti-IgE mAb, is the first targeted biologic therapeutic approved for the treatment of moderate-to-severe persistent allergic asthma (AA) that remains uncontrolled despite high-dose inhaled corticosteroids plus other controller medications. Since its initial licensing for use in adults and adolescents 12 years of age and older, the clinical efficacy, safety, and tolerability of omalizumab have been demonstrated in several published clinical trials in children aged 6 to less than 12 years with moderate-to-severe AA. These studies supported the approval of the pediatric indication (use in children aged ≥6 years) by the European Medicines Agency in 2009 and the US Food and Drug Administration in 2016. After this most recent change in licensing, we review the outcomes from clinical trials in children with persistent AA receiving omalizumab therapy and observational studies from the past 7 years of clinical experience in Europe. Data sources were identified by using PubMed in 2016. Guidelines and management recommendations and materials from the recent US Food and Drug Administration's Pediatric Advisory Committee meeting are also reviewed.
Psoriasis, a chronic immune-mediated disease, is associated with an increased risk of cardiovascular events and mortality. Secukinumab selectively neutralizes IL-17A and has reported high efficacy ...with a favorable safety profile in various psoriatic disease manifestations. Subsequent to the 12-week randomized, placebo-controlled, double-blind treatment period, patients with moderate-to-severe psoriasis received secukinumab for 40 weeks. Vascular inflammation using 18F-2-fluorodeoxyglucose–positron emission tomography/computed tomography imaging and blood-based cardiometabolic was assessed at week 0, 12, and 52. The difference in change in aortic inflammation from baseline to week 12 for secukinumab (n = 46) versus placebo (n = 45) was –0.053 (95% confidence interval = –0.169 to 0.064; P= 0.37). Small increases in total cholesterol, low-density lipoprotein, and low-density lipoprotein particles, but no changes in markers of inflammation, adiposity, insulin resistance, or predictors of diabetes, were observed with secukinumab treatment compared with placebo. At week 52, reductions in TNF-α (P= 0.0063) and ferritin (P= 0.0354), and an increase in fetuin-A (P= 0.0024), were observed with secukinumab treatment compared with baseline. No significant changes in aortic inflammation or markers of advanced lipoprotein characterization, adiposity, or insulin resistance were observed with secukinumab treatment compared with baseline. Secukinumab exhibited a neutral impact on aortic vascular inflammation and biomarkers of cardiometabolic disease after 52 weeks of treatment.
Background Although specific immunotherapy is a valuable treatment option for patients with allergic asthma, the potential for systemic allergic reactions has limited its use, especially for patients ...with symptomatic disease. Objective To evaluate omalizumab's effect on the tolerability of specific immunotherapy in patients with symptomatic persistent asthma not adequately controlled with inhaled corticosteroids. Methods This multicenter, double-blind, parallel-group study randomized patients to treatment with omalizumab or placebo, after which they received specific immunotherapy to at least 1 of 3 perennial aeroallergens (cat, dog, and house dust mite) according to a 4-week, 18-injection cluster regimen, followed by 7 weeks of maintenance therapy. The primary efficacy variable, a systemic allergic reaction after immunotherapy, was analyzed by using the Cochrane-Mantel-Haenszel test. Results A total of 248 randomized patients (126 omalizumab, 122 placebo) received at least 1 dose of immunotherapy and were evaluated for efficacy. Patients receiving omalizumab experienced significantly fewer systemic allergic reactions to immunotherapy than those receiving placebo (17/126 13.5% vs 32/122 26.2%; P = .017; 95% CI, 2.91% to 22.56%) and had fewer respiratory-related (grade 3) systemic allergic reactions (6 vs 24, respectively). Grade 4 reactions were reported in 2 patients in each group. More omalizumab patients were able to reach the target maintenance immunotherapy dose (110 87.3% vs 88 72.1%, respectively; P = .004). Conclusion Use of omalizumab in patients whose asthma was symptomatic despite use of inhaled corticosteroids was associated with fewer systemic allergic reactions to specific immunotherapy and enabled more patients to achieve the target immunotherapy maintenance dose.
Adults and adolescents were included in 3 phase 3 omalizumab trials in chronic idiopathic urticaria (CIU): ASTERIA I, ASTERIA II, and GLACIAL.
To describe the baseline clinical profile of adolescent ...patients with CIU enrolled in the omalizumab trials to add to the limited literature available on CIU in this population.
Data for patient demographics, baseline clinical disease characteristics, medical history, and previous CIU medication information (not efficacy assessments) from phase 3 omalizumab trials were pooled and descriptive statistical analyses performed for adolescent (12 to <18 years old) and adult (≥18 years old) subgroups. Inferential analysis was inappropriate, partly because of small sample size in the adolescent subgroup.
The pooled population of 975 patients with CIU included 39 adolescents (4.0%). Demographics of adolescents and adults with CIU were similar, but compared with adults, fewer adolescents had positive Chronic Urticaria Index test results. Baseline clinical disease characteristics were also similar between the subgroups, with the number of previous CIU medications slightly lower in adolescents compared with adults. Medical history and existing conditions in adolescents tended to be more allergy than cardiovascular related, and fewer experienced angioedema compared with adults.
Pooled data indicate differences in baseline demographic and clinical characteristics between adult and adolescent patient subgroups. This finding helps augment our understanding of the clinical profile of CIU in adolescents, but larger-scale studies in this population are warranted.

Rationale The Epidemiology and Natural History of Asthma: Outcomes and Treatment Regimens (TENOR-I) examined patients with severe/difficult-to-treat asthma.
Methods This is a post-hoc descriptive analysis of pooled baseline data from three omalizumab trials in CIU/CSU patients who remained symptomatic despite H1-antihistamine treatment and ...H2-antihistamines and/or leukotriene receptor antagonists (LTRA) in one study.
The most common positive IgE tests for atopic patients were perennial aero-allergens: cat dander (59.7%), dog dander (53.7%) and Dermatophagoides farina dust mite (43.7%).
Asthma guidelines advocate maintaining asthma control while minimizing corticosteroid exposure.
To assess the reduction in corticosteroid burden during long-term treatment and the corresponding ...impact of this reduction on asthma control, lung function, and inflammation in patients with moderate to severe allergic asthma.
We conducted a pooled analysis (N = 1,071) of 2 similarly designed, randomized, double-blind, placebo-controlled omalizumab trials and their extension phases. Each study included a 16-week steroid-stable phase, a 12-week steroid-reduction phase, and a 24-week extension phase. Patients received subcutaneous omalizumab (minimum, 0.016 mg/kg/IU (IgE/mL) every 4 weeks) or placebo every 2 or 4 weeks. Outcomes included change from baseline in inhaled corticosteroid dose, number of oral corticosteroid bursts, and other clinical measures, including asthma exacerbations and change in asthma quality-of-life score (questionnaire), lung function, and eosinophil count.
The median reduction from baseline in inhaled corticosteroid dose (beclomethasone dipropionate equivalent dose) by the completion of the extension phase was greater for the omalizumab group than for the placebo group (-420.0 vs -252.0 μg/d; P < .001). During that time, omalizumab-treated patients required fewer oral corticosteroid bursts overall for treatment of acute exacerbations (mean, 0.2 vs 0.3; relative risk, 0.56; 95% confidence interval, 0.41 to 0.76; P < .001) and demonstrated greater improvements in measures of asthma control.
The addition of omalizumab to baseline therapy in patients 12 years or older with moderate to severe persistent allergic asthma resulted in a durable reduction in the overall steroid burden and improvement in other clinical measures of asthma control.
Moderate-to-severe scalp psoriasis has not been evaluated in prospective trials of patients without moderate-to-severe body psoriasis.
Evaluate the efficacy and safety of secukinumab in ...moderate-to-severe scalp psoriasis.
In this 24-week, double-blind, phase 3b study, 102 patients were randomized 1:1 to subcutaneous secukinumab 300 mg or placebo at baseline, weeks 1, 2, and 3, and then every 4 weeks from week 4 to 20. The primary efficacy variable was 90% improvement of Psoriasis Scalp Severity Index (PSSI 90) score from baseline to week 12.
At week 12, PSSI 90 (secukinumab 300 mg vs placebo, 52.9% vs 2.0%) and Investigator's Global Assessment modified 2011 scalp responses of 0 or 1 (secukinumab 300 mg vs placebo, 56.9% vs 5.9%) were significantly greater with secukinumab 300 mg than placebo (P < .001 for both). In addition, significantly more patients achieved complete clearance of scalp psoriasis at week 12 with secukinumab 300 mg than placebo (35.3% vs 0%; P < .001). The median time to 50% reduction in PSSI score was 3.29 weeks with secukinumab 300 mg. The safety profile of secukinumab was consistent with previous phase 3 studies.
There was no active comparator arm.
Secukinumab is efficacious and well-tolerated for patients with extensive moderate-to-severe scalp psoriasis.
