MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Data from more than 20,000 patients with non-valvular atrial fibrillation (NVAF) were included in this study and the results demonstrate that Pradaxa® (dabigatran etexilate mesylate) was associated with a lower risk of stroke and major bleeding compared to warfarin. The study analyzed 7,245 PRADAXA patients and 14,490 warfarin patients with NVAF who had no prior use of an oral anticoagulant (OAC), using data from an administrative claims database from October 1, 2010, to April 30, 2014.

Compared to warfarin, PRADAXA was associated with a 26 percent reduced risk of stroke (HR, 0.74; 95% Cl, 0.58-0.94) and a 20 percent reduced risk of major bleeding (HR, 0.80; 95% Cl, 0.69-0.92). PRADAXA was associated with a lower risk for serious secondary outcomes, including a 68 percent reduced risk of hemorrhagic stroke (HR, 0.32; 95% Cl, 0.14-0.76), an 18 percent reduced risk of major extracranial bleeding (HR, 0.82; 95% Cl, 0.70-0.96), a 48 percent reduced risk of venous thromboembolism (HR, 0.52; 95% Cl, 0.38-0.70), and a 27 percent reduced risk of death (HR, 0.73; 95% Cl, 0.61-0.88).

MedicalResearch.com: What should readers take away from your report?
Response: These results support the benefits of PRADAXA therapy for patients with NVAF and are consistent with those of previous studies evaluating PRADAXA and warfarin. Through a robust clinical trial, Pradaxa was proven superior to warfarin in reducing the risk of stroke in patients with NVAF.

MedicalResearch.com: What recommendations do you have for future research as a result of this study?

Response: Real-world data are critical for improving our understanding of treatment for patients with chronic conditions such as NVAF. We believe by working with diverse stakeholders to continue to study PRADAXA in the real world, we can help the community better understand gaps in treatment, identify opportunities to improve care and increase patient and physician assurance in treatment decisions.

MedicalResearch.com: Is there anything else you would like to add?

Response: Pradaxa has the longest real-world experience of any available NOAC. This research includes seven clinical trials with more than 32,000 patients and real-world experience through 11 studies and assessments, including more than 120,000 PRADAXA patients with NVAF.
