Anti-TNF dose escalation and drug sustainability in Crohn's disease : Data from the nationwide administrative database in Hungary

A significant percentage of patients receiving anti-tumor necrosis factor alpha (anti-TNFα) agents lose clinical response over time. This study aims to provide representative real-world data on anti-TNFα drug sustainability, prevalence and predictors of anti-TNFα dose escalation.In this nationwide, retrospective study, patients receiving infliximab or adalimumab therapy between 2013 and 2016 were included using the administrative claims database of the Hungarian National Health Insurance Fund. Demographic characteristics, drug sustainability, dose escalation, use of parallel medications were analyzed.476 infliximab and 397 adalimumab patients were included. Dose escalation was observed in 7%, 9% and 22% of patients receiving originator/biosimilar infliximab and adalimumab during the complete follow-up, respectively. Dose escalation was associated with shorter disease duration (OR = 1.75, p = 0.026) and corticosteroid use. Drug retention rates were 62.7%, 72.3%, 75.4% after 1 year follow-up for Remicade®, Inflectra® and Humira®, which decreased to 38.3% and 52.1% for Remicade® and Humira® at 3 years. Drug sustainability was affected by steroid use prior biologic initiation in adalimumab treated patients (HR = 2.04, p < 0.001), while in infliximab treated patients dose escalation (HR = 0.51, p = 0.02) and gender (HR = 1.39, p = 0.033) were predictors of treatment discontinuation.Dose escalation rates were lower in this real-world administrative database study for both adalimumab and infliximab compared to published data. Drug retention rates were overall satisfactory, with no apparent difference between the legacy and biosimilar infliximab

Secondary malignancies and survival of FCR‐treated patients with chronic lymphocytic leukemia in Central Europe

Abstract This is the first large‐scale cross‐country analysis of patients with chronic lymphocytic leukemia (CLL) aimed to evaluate the incidence, types, and key prognostic factors of secondary malignancies, and to assess the impact on overall survival based on retrospective claims data from three Central European countries. We analyzed 25,814 newly diagnosed CLL patients from Czechia, Hungary, and Poland; 10,312 (39.9%) patients were treated for CLL in study periods between 2004 and 2016. Out of the treated patients, 1986 (19.3%) received the FCR therapy in the first line and 779 (7.6%) received FCR in subsequent lines. We observed that 33.7% of treated patients developed secondary malignancies during the study. Based on country estimates, the probability to develop a secondary malignancy within 4 years since starting the first‐line FCR therapy ranged between 28.0% and 36.8%. We found the age at diagnosis, male gender, any malignancy prior to the CLL diagnosis, and the CLL treatment to be the key risk factors for developing secondary malignancies. Specifically, the FCR therapy was a statistically significant (p < 0.001) prognostic factor for risk increase with the hazard ratio between 1.46 and 1.60. Across the three Central European countries, we observed consistent results indicating FCR increased the risk of secondary malignancies in CLL patients. We conclude that secondary malignancies are clearly an undervalued burden for CLL patients, caregivers, and the healthcare system. When evaluating new therapies in regulatory and reimbursement decision making, the factor of secondary malignancies deserves deeper considerations
