Background: Biologics are used to treat moderate-to-severe psoriasis, and persistence to biologics may reflect clinical effectiveness. Limited information describing how biologics are used in patients with moderate-to-severe psoriasis in Asian countries is available. We conducted a population-based, retrospective, new user cohort study using the National Health Insurance Research Database (NHIRD) in Taiwan to assess treatment persistence and adherence to biologics.Methods: Adults with a diagnosis of psoriasis between 01 January 2015 and 31 December 2017 were identified in the NHIRD (ICD-9-CM 696.1; ICD-10 L40.0). New users were patients who initiated treatment with etanercept, adalimumab, ustekinumab or secukinumab between 01 January 2015 and 31 December 2017. All eligible patients were followed until 31 December 2018, death or disenrollment. Kaplan-Meier analysis was conducted to estimate persistence of treatment for index biologics. A Cox-proportional hazard regression model was used to compare risks of biologic discontinuation between biologic groups. Adjustments for potential confounding factors (age, gender and Charlson comorbidity index score) were made in the Cox model.Results: There were 1,397 new biologic users with psoriasis during the study period. The ratio men:women was approximately 4:1. Mean age of patients ranged from 44.6 to 47.7 years across exposure groups. The 1-year/2-years persistence rates were 94.2%/84.9% for ustekinumab, 96.2%/not calculated (due to too few patients at year 2) for secukinumab, 66.0%/29.9% for etanercept, and 59.8%/40.3% for adalimumab. The risk of discontinuation was significantly lower in patients initiating ustekinumab compared with adalimumab (hazard ratio adjusted for age, sex and co-morbidities 0.289, 95%CI 0.247–0.339, p < 0.0001). Drug survival was significantly higher for ustekinumab compared with adalimumab and etanercept (log-rank test p < 0.0001). The proportions of patients with 1-year/2-years medication possession ratios of ≥80% were 95.3%/92.0% for ustekinumab, 98.1%/not calculated for secukinumab, 89.4%/83.1% for etanercept, and 70.8%/59.4% for adalimumab.Limitations: Clinical improvement and response to treatment data were not available.Conclusion: There was relatively high persistence amongst biologic users with psoriasis in Taiwan. There is a trend towards greater persistence of ustekinumab compared to other biologics, the magnitude of which depends on the treatment gap used for its calculation. This study provides real-world evidence that may facilitate optimal treatment choice.

Background To ascertain the efficacy, safety, and immunogenicity from existing evidence via conducting a meta-analysis of randomized controlled trials between biosimilar and originator insulins. Methods The PubMed, Cochrane Library, EMBASE, and ClinicalTrails.gov were searched to identify head-to-head randomized controlled trials (RCTs) that directly compare the efficacy and safety of biosimilar insulin and its originator. Efficacy was assessed by change of HbA1C, fasting plasma glucose (laboratory or self-monitoring of blood glucose (SMBG)), and change all mean of 7 points- or 8 points- SMBG. Safety was assessed by change in proportion hypoglycemia and serious hypoglycemia. The occurrence of anti-insulin antibodies (AIAs) was also evaluated. Results Fourteen RCTs with 6188 patients from different countries were included. Data were pooled using a random-effects model and were expressed as the mean difference (MD), odds ratio (OR), and 95% confidence interval (CI). In efficacy, Insulin biosimilar products showed similar in change of HbA1C at weeks 26 and 52, the MD were 0.03 (95% CI − 0.02 to 0.07, p = 0.28), and 0.05 (95% CI − 0.05 to 0.15, p = 0.36), respectively. The proportion of HbA1C less than 7% at endpoint, the OR were 1.04 (95% CI 0.89 to 1.20, p = 0.64). The change of fasting plasma glucose (laboratory or SMBG) mmol/L in 24–52 weeks and change all mean of 7 points−/8 points- SMBG mmol/L in 24–52 weeks, the MD were 0.02 (95% CI − 0.20 to 0.24, p = 0.87) and − 0.34 (95% CI − 1.35 to 0.67, p = 0.51), respectively. In occurrence of hypoglycemia (≥ 1 events) and severe hypoglycemia, the OR were 0.96 (95% CI 0.85 to 1.09, p = 0.52) and 1.06 (95% CI 0.85 to 1.31, p = 0.62). The AIA was 1.02 (95% CI 0.90 to 1.16, p = 0.76). Analysis stratified by type of diabetes and duration of insulin. There was no significant difference between the biosimilar and their reference group in a different type of diabetes and different duration of insulin. Conclusions Insulin biosimilar showed comparable characteristics with the reference drug in terms of efficacy, safety, immunogenicity, through comprehensive and specific conventional meta-analysis.

BackgroundTo date, there has been no large-scale, real-world study of the health-related quality of life outcomes for patients using tumor treating fields (TTFields) therapy for glioblastoma (GBM) treatment.MethodsA survey was mailed to 2,815 patients actively using TTFields for treatment of GBM in the USA (n = 2,182) and Europe (n = 633). The survey included patient-reported demographic and clinical information, as well as EuroQol’s EQ-5D-5L and visual analogue scale (EQ-VAS) overall health score.ResultsA total of 1,106 applicable patients responded to the survey (USA = 782 and Europe = 324), with a mean age of 58.6 years (SD = 12.3). The average time since diagnosis and time using TTFields were 21.5 months (SD = 25.1) and 13.5 months (SD = 13.2), respectively. Over 61% of patients had been diagnosed at least 1 year prior and 28.4% at least 2 years prior; 45 patients (4.2%) had been diagnosed at least 5 years prior. Progressed disease was reported in 307 patients, while 690 reported non-progressed disease. Regression analyses showed that GBM disease progression and older age had predictable negative associations (p p p p p p p p p p p p p p p p ConclusionThis is the largest real-world study of patient-reported quality of life in GBM and TTFields treatment to date. It shows unsurprising negative associations between quality of life and disease progression and older age, as well as more novel, positive associations between quality of life and longer time since diagnosis and time using TTFields therapy.
