ABSTRACT

INTRODUCTION: Edoxaban had a positive risk-benefit ratio for the treatment of venous thromboembolism (VTE) compared to conventional therapy with warfarin. The objective of this analysis of the ongoing ETNA-VTE Europe study was to assess the real-world benefits and risks of edoxaban during the first 3 months of treatment, the highest risk period for further VTE events. METHODS: ETNA-VTE Europe is a prospective, non-interventional, post-authorization study, conducted in eight European countries. Participants had initial or recurrent acute VTE (deep vein thrombosis [DVT] and/or pulmonary embolism [PE]) that occurred ≤2 weeks prior to enrolment and received edoxaban therapy. RESULTS: The analysis set included 2672 patients (PE ± DVT, n = 1117; DVT only, n = 1555); mean age 62.9 ± 16.0 years, bodyweight 81.9 ± 17.4 kg, estimated glomerular filtration rate 95.4 ± 42.8 mL/min; 46.4% were female. Overall, 66.4% of patients (PE ± DVT, 68.5%; DVT-only, 64.8%) received heparin lead-in treatment for at least 5 days. Most patients (87.7%) received edoxaban at a dose of 60 mg once daily. Event rates at 3 months were: recurrent VTE 0.34% (n = 9), major bleeding 0.97% (n = 26), all-cause mortality 0.79% (n = 21). Rates were numerically higher in the PE ± DVT group compared with the DVT-only group (recurrent VTE, 0.45% (n = 5) versus 0.26% (n = 4); major bleeding, 1.34% (n = 15) versus 0.71% (n = 11); and all-cause mortality 1.16% (n = 13) versus 0.51% (n = 8)). CONCLUSIONS: The results support the safety and effectiveness of edoxaban in a general VTE population during the most critical time period, the first 3 months. The outcomes of this study extend the principal efficacy and safety data on edoxaban into the routine clinical practice setting.

ABSTRACT

INTRODUCTION: Edoxaban has proven its efficacy and safety in the ENGAGE AF-TIMI 48 and HOKUSAI-VTE clinical trials. Clinical practice patients, however, may differ from those enolled in clinical trials. We aimed to compare patients from the HOKUSAI-VTE clinical trial with those treated in clinical practice. MATERIALS AND METHODS: ETNA-VTE-Europe is a prospective, non-interventional post-authorisation safety study conducted in eight European countries. RESULTS: A total of 2,879 patients presenting with acute symptomatic venous thromboembolism (VTE) were enrolled at 339 sites. Of the 2,680 patients with complete data, 23.6% reported prior VTE and 2.8% had a history of bleeding. Patients in ETNA-VTE were older (65vs.57 years), more likely to be female (46.5vs.39.8%) and had a higher prevalence of chronic venous insufficiency (11.1vs.1.6%) than those in the European cohort of the HOKUSAI-VTE trial (n=1,512). Bodyweight and creatinine clearance were substantially lower in clinical practice. Edoxaban dosing was adherent to label in 90% of patients, with higher (60 mg) and lower than recommended doses (30 mg) used in 6.6% and 3.3% of the patients, respectively. Heparin lead-in was used in 84.7% of the patients overall, and was more frequently used in patients with PE than patients with DVT only (91.3% vs. 80.1%; p<0.0001). CONCLUSIONS: These data reinforce the largely appropriate use of edoxaban in routine clinical practice, where the study population differs from those in prior randomised controlled trials.

ABSTRACT

BACKGROUND: Venous thromboembolism (VTE, including deep vein thrombosis [DVT] and pulmonary embolism [PE]) has an annual incidence rate of 104-183 per 100,000 person-years. After a VTE episode, the two-year recurrence rate is about 17%. Consequently, effective and safe anticoagulation is paramount. Edoxaban is a direct oral anticoagulant (DOAC) approved VTE treatment. Current safety and efficacy data are derived from clinical trials, and information about treatment durations beyond 12 months are not available. METHODS: ETNA-VTE-Europe is an 18-month prospective, single-arm, non-interventional, multinational post-authorisation safety study. Approximately 310 sites across eight European countries (Austria, Belgium, Germany, Ireland, Italy, the Netherlands, Switzerland and the United Kingdom) will participate in the study, with the intention to represent the regional distributions of centres, healthcare settings and specialties. An estimated cohort of 2700 patients will be recruited, the only enrolment criteria being acute symptomatic VTE, no participation in an interventional study, and treating physician decision to prescribe edoxaban independently from the registry. Data from patient medical records and/or telephone interviews will be collected at baseline, 1, 3, 6, 12 and 18 months. The primary objective is to evaluate the 18-month rate of symptomatic VTE recurrence in patients with VTE treated with edoxaban outside a clinical trial. The co-primary objective is to evaluate the real-world rates of bleeding and adverse drug reactions. Secondary outcomes include rates of other patient-relevant safety events, adherence to and discontinuation of edoxaban. Furthermore, 12-month ETNA-VTE-Europe data will be considered in the context of those for patients receiving different anticoagulants in the PREFER in VTE registry and Hokusai-VTE clinical trial. CONCLUSIONS: ETNA-VTE-Europe will allow the safety and effectiveness of edoxaban to be evaluated over an extended period in acute symptomatic VTE patients encountered in routine clinical practice. Findings will be informative for European practitioners prescribing edoxaban as part of real-world VTE treatment/prevention. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02943993.

ABSTRACT

BACKGROUND: Safety of a sixth consecutive dose of acellular pertussis vaccine in adolescents was assessed in a 2-armed, randomized study. METHODS: Adolescents who had received 5 doses of acellular pertussis vaccine combined with diphtheria and tetanus toxoids (6-dose group) received 1 dose of reduced 5-component acellular pertussis vaccine combined with tetanus toxoid and reduced diphtheria toxoid (Tdap). Adolescents who had received a primary series of 3 doses of whole-cell pertussis and 1 acellular or whole-cell pertussis booster received 1 dose of Tdap vaccine (5-dose group). RESULTS: Of 214 participants, 176 (82%) reported an injection-site reaction with pain (80%), erythema (22%), and swelling (19%) most frequently reported. A systemic reaction was reported by 169 of 214 (79%) with myalgia (66%), headache (42%), malaise (39%), and fever (9%) most frequently reported. The overall rate of solicited reactions was lower in the 6-dose group than in the 5-dose group (for injection-site reactions: 76.1% vs. 89.7%; for systemic reactions 72.6% vs. 86.6%). Significant differences were observed for injection-site pain, erythema, and for grade 1 or grade 2 increases in arm circumference. Fever, myalgia, and headache were reported at a significantly lower rate in the 6-dose group. Swelling >10 cm was observed in 5 patients (2%), 4 in the 5-dose group. CONCLUSIONS: Tdap vaccine was safe when given to adolescents who had received 5 prior doses of acellular pertussis vaccine.
