Long-term health benefits of stroke prevention with apixaban versus vitamin K antagonist warfarin in patients with non-valvular atrial fibrillation in Germany: a population-based modelling study

The societal impact of obinutuzumab in the first-line treatment of patients with follicular lymphoma in Germany

In this study, we assessed the productivity gains associated with the use of obinutuzumab in combination with chemoimmunotherapy (G-chemo) in first-line treatment among follicular lymphoma patients. Health benefits, measured as an increase in progression-free survival, were translated into productivity gains in both paid and unpaid work using gross value added as productivity measure. From 2017 to 2030, 11,870 overall progression-free years can be gained by utilizing obinutuzumab. These progression-free years correspond to undiscounted productivity gains of about €187.9 million in paid work and about €535.9 million in unpaid work. Our study shows that the benefits of the use of obinutuzumab in the first-line treatment of follicular lymphoma extend beyond clinical advantages.

Safety and Efficacy of Oral Anticoagulants Therapies in Patients With Atrial Fibrillation Undergoing Percutaneous Coronary Intervention: A Network Meta-Analysis

Background:

Different antithrombotic treatments, from vitamin K antagonists to direct oral anticoagulants (DOACs), are available to reduce ischemic risks in patients with atrial fibrillation (AF) after percutaneous coronary intervention (PCI). Objective: To synthetize evidence about the benefit–risk ratio of antithrombotic treatments and their combinations in patients with AF and PCI.

Methods:

A network meta-analysis and a stochastic multicriteria acceptability analysis (SMAA) were performed including randomized controlled trials (RCT) that evaluate antithrombotic treatments in adults with AF and PCI. Searches were conducted in PubMed and Scopus (updated November-2019). Outcomes compared included bleeding, stroke, and death (Prospero registration: CRD42019146813).

Results:

Five RCTs were included (11 532 patients). Vitamin K antagonists + dual antiplatelet therapy was associated with major bleeding (odds ratio: 0.52 [95% CI: 0.32-0.86]) compared to DOAC + P2Y12. No statistical differences were found among DOAC regimens for the main outcomes, including bleeding, stroke, and death. Surface under the cumulative ranking curve analysis (SUCRA) and SMAA demonstrated edoxaban 60 mg + P2Y12 inhibitor as the worst option (28%). Apixaban 5 mg + P2Y12 inhibitor was the safest alternative (63%) in all scenarios.

Conclusions:

Insufficient evidence on the clinical superiority among anticoagulant regimens exists, although apixaban slightly stands out. Edoxaban was associated with more adverse events. To strength this evidence, well-designed, low risk of bias clinical trials are needed. Cost-minimization analyses are required to provide further information for clinical decision-making.

Patient characteristics and stroke and bleeding events in nonvalvular atrial fibrillation patients treated with apixaban and vitamin K antagonists: a Spanish real-world study

Aim: To compare the risk of stroke, systemic thromboembolism and bleeding, in patients initiating apixaban or acenocoumarol for the treatment of nonvalvular atrial fibrillation. Methods: An observational, retrospective study was performed using medical records of patients who initiated apixaban or acenocoumarol between 2015 and 2017. Propensity score matching was used to match patients; stroke, systemic thromboembolism, major and minor bleeding events were compared between the matched patients. Results: Patients who were prescribed apixaban had a lower rate of systemic embolism/stroke (hazard ratio [HR] = 0.54; 95% CI: 0.38–0.78; p = 0.001), minor bleeding (HR = 0.64; 95% CI: 0.52–0.79; p < 0.001) and major bleeding (HR = 0.51; 95% CI: 0.37–0.72; p < 0.001). Conclusion: Patients prescribed apixaban for the treatment of nonvalvular atrial fibrillation had lower rates of thromboembolic events and minor/major bleeding than patients on acenocoumarol.
