Trading between perceived risks and benefits related to biosimilar biological treatment in Crohn’s disease; discrete choice experiment among gastroenterologists

Objective: The objective of the study is to explore preferences of gastroenterologists for biosimilar drugs in Crohn’s Disease and reveal trade-offs between the perceived risks and benefits related to biosimilar drugs. Method: Discrete choice experiment was carried out involving 51 Hungarian gastroenterologists in May, 2014. The following attributes were used to describe hypothetical choice sets: 1) type of the treatment (biosimilar/originator) 2) severity of disease 3) availability of continuous medicine supply 4) frequency of the efficacy check-ups. Multinomial logit model was used to differentiate between three attitude types: 1) always opting for the originator 2) willing to consider biosimilar for biological-naïve patients only 3) willing to consider biosimilar treatment for both types of patients. Conditional logit model was used to estimate the probabilities of choosing a given profile. Results: Men, senior consultants, working in IBD center and treating more patients are more likely to willing to consider biosimilar for biological-naïve patients only. Treatment type (originator/biosimilar) was the most important determinant of choice for patients already treated with biologicals, and the availability of continuous medicine supply in the case biological-naïve patients. The probabilities of choosing the biosimilar with all the benefits offered over the originator under current reimbursement conditions are 89% vs 11% for new patients, and 44% vs 56% for patients already treated with biological. Conclusions: Gastroenterologists were willing to trade between perceived risks and benefits of biosimilars. The continuous medical supply would be one of the major benefits of biosimilars. However, benefits offered in the scenarios do not compensate for the change from the originator to the biosimilar treatment of patients already treated with biologicals

Comparison of the efficacy and safety of commercially available fixed ratio combinations of insulin degludec/liraglutide (IDegLira) and insulin glargine/lixisenatide (iGlarLixi) - a network meta-analysis

AIMS: To compare the efficacy and safety of commercially available fixed ratio combinations (FRC) of glucagon-like peptide 1 receptor agonists (GLP-1RA) and basal insulins by a network meta-analysis (NMA) of randomised controlled trials (RCT) of type 2 diabetes patients. METHODS: We report a systematic review and network meta-analyses of RCTs of type 2 diabetes patients randomized to FRCs or to their components for ≥24-weeks reported in PubMed or ClinicalTrials.gov until 28/FEB/2022. Primary outcome was attained HbA1c. Secondary outcomes included fasting plasma glucose, change in body weight, and incident hypoglycaemia. Treatment effects were estimated as mean differences and standard errors (MD; [SE]) or odds ratios (OR) with 95% confidence intervals (95%CI) using iGlarLixi as reference. RESULTS: We included 29 RCTs of the 1404 papers identified. No direct comparison between FRCs were found. After excluding some insulin capped trials to reach model consistency, both FRCs were more efficacious regarding HbA1c than their components, however no difference between FRCs were found (MD: -0.10 [SE: 0.10]%). The effect of IDegLira (-0.47 [0.24] mmol/l) and basal insulins was similar to that of iGlarLixi (ref.) on fasting glucose, while GLP-1RA had lower efficacy than iGlarLixi. Weight gain was lower with GLP-1RAs and IDegLira (-0.72 [0.32] kg) than iGlarLixi (ref.) and higher with basal insulins. Incident hypoglycemia (based on different definitions) was least frequent with GLP-1RAs followed by IDegLira (OR 0.78 95%CI 0.39-1.57), iGlarLixi (ref.) and basal insulins. CONCLUSIONS: Regarding HbA1c, both FRCs were more efficacious over their individual components with similar efficacies of the two FRCs

The burden of Clostridium difficile infection between 2010 and 2013: trends and outcomes from an academic center in Eastern Europe

Modeling is now an essential ingredient in business process management and information systems development. The general usefulness of models in these areas is therefore generally accepted. It is also undisputed that the quality of the models has a significant impact on their usefulness. In the literature we can find any number of quality metrics, but hardly any study that investigates their relation with (perceived) usefulness and none that considers their relative impact on usefulness. We take a look at some of the most frequent quality dimensions and their relative impact on the perceived usefulness of models

Efficacy and safety of the biosimilar infliximab CT-P13 treatment in inflammatory bowel diseases: a prospective, multicentre, nationwide cohort

Background and Aims: Biosimilar infliximab CT-P13 is approved for all indications of the originator product in Europe. Prospective data on its efficacy, safety, and immunogenicity in inflammatory bowel diseases are lacking. Methods: A prospective, nationwide, multicentre, observational cohort was designed to examine the efficacy, safety, and immunogenicity of CT-P13 infliximab biosimilar in the induction treatment of Crohn’s disease [CD] and ulcerative colitis [UC]. Demographic data were collected and a harmonised monitoring strategy was applied. Early clinical remission, response, and early biochemical response were evaluated at Week 14, steroid-free clinical remission was evaluated at Week 30. Therapeutic drug level was monitored using a conventional enzyme-linked immunosorbent assay. Results: In all, 210 consecutive inflammatory bowel disease [126 CD and 84 UC] patients were included in the present cohort. At Week 14, 81.4% of CD and 77.6% of UC patients showed clinical response and 53.6% of CD and 58.6% of UC patients were in clinical remission. Clinical remission rates at Week 14 were significantly higher in CD and UC patients who were infliximab naïve, compared with those with previous exposure to the originator compound [ p < 0.05]. Until Week 30, adverse events were experienced in 17.1% of all patients. Infusion reactions and infectious adverse events occurred in 6.6% and 5.7% of all patients, respectively. Conclusions: This prospective multicentre cohort shows that CT-P13 is safe and effective in the induction of clinical remission and response in both CD and UC. Patients with previous infliximab exposure exhibited decreased response rates and were more likely to develop allergic reactions

Autoregressive cross-lagged models of IMPACT-III and Pediatric Crohn's Disease Activity Indexes during one year infliximab therapy in pediatric patients with Crohn's disease.

BACKGROUND Quality of life (QoL) is an important outcome measure in the evaluation of therapies for inflammatory bowel disease. The primary aim of this study was to determine the effect of one year infliximab treatment on QoL and clinical parameters in pediatric patients with Crohn's diseases (CD). METHODS Our prospective study involved 51 children with conventional therapy resistant, severe CD (mean age: 15.25years, range: 11-18years). Infliximab was given according to the protocol (5mg/kg, at weeks 0, 2, 6 and every 8weeks). During the infliximab courses QoL of patients was evaluated by IMPACT-III questionnaire at weeks 0, 6, 30 and 53. At the same time, the Pediatric Crohn's Disease Activity Index (PCDAI) score was calculated. Moreover, serum C-reactive protein (CRP), serum platelets and serum albumin were followed up. Auto-regressive, cross-lagged models were used to assess relation between QoL and the clinical parameters. RESULTS The initial IMPACT-III scores [median, percentile 25-75 (pc 25-75) at week 0: 115, 102.5-130.25] increased significantly (p<0.001) following infliximab therapy at week 54 (median: 141.5, 124.5-153.75). Clinical and laboratory parameters also improved significantly (p<0.001). Auto-regressive regression coefficients (β value) were significant between each variable over time. The strongest cross-lagged relations were observed between IMPACT-III and serum albumin, IMPACT-III and platelets. Reliability test of IMPACT-III revealed an excellent level of internal consistency (Cronbach's alpha=0.931). CONCLUSION Infliximab treatment has beneficial clinical effect which is confirmed by decrease of PCDAI and increase of IMPACT-III. Autoregressive regression analysis showed regression relation between IMPACT-III and PCDAI and laboratory parameters

Decreasing trends in hospitalizations during anti-TNF therapy are associated with time to anti-TNF therapy: Results from two referral centres

The purpose of this study is to give an insight into how school children in year six, in Sweden, value and view grades. In Sweden, currently there are many debates on whether schools should have grading systems and if so, in which school year they should be introduced. In the present study seven children (3 boys and 4 girls), attending year six, were divided into two focus groups; that were simultaneously conducted. In the focus groups, the children discussed their views, values and their experiences in regard to grades. The results discerned from the two focus groups were that the seven participating school children felt that there was value and merit in receiving grades because they gained a better understanding of their own academic performance based on the grades they received. Additionally, however, the children acknowledged that they also do experience negative emotional effects from receiving grades, such as stress and the de-evaluation of their capabilities in comparison to their schoolmates. Nevertheless, the participating children perceived that grades were necessary and believed that the grading system should begin to be enforced in either year four, or year five, for the most optimal effect
