Study results outline dabigatran etexilate as potential thromboprophylaxis

therapy for patients undergoing total hip replacement surgery

RIDGEFIELD, Conn., Sept. 13 /PRNewswire/ -- Boehringer Ingelheim today announced that the September 15 issue of The Lancet will publish results from the RE-NOVATE study, which investigated dabigatran etexilate as a potential therapy for patients undergoing total hip replacement surgery(1). The results from this study demonstrate that both doses (220mg and 150mg) of the oral direct thrombin inhibitor, dabigatran etexilate, administered for a median of 33 days, were non-inferior to injectable enoxaparin in reducing the risk of venous thromboembolism (VTE) after total hip replacement surgery with similar safety.

The primary endpoint of this trial was a composite consisting of total venous thromboembolic events and all-cause mortality during treatment, which occurred in 6.0% of the 220mg group and 8.6% of the 150mg group taking dabigatran etexilate, versus 6.7% of the enoxaparin group. Importantly, a pre-specified secondary outcome of major venous thromboembolism and venous thromboembolism-related mortality was also similar between groups, occurring in 3.1% of the 220mg group and 4.3% of the 150mg group taking dabigatran etexilate, versus 3.9% of the enoxaparin group.

Anticoagulation-related bleeding is the primary safety concern during hip replacement surgery, since major bleeding into the replaced joint can have a detrimental impact on clinical outcome(2). Generally, few major bleeding events were reported, occurring at 2.0% in the 220mg group and 1.3% in the 150mg group for dabigatran etexilate, versus 1.6% in the enoxaparin group. Notably about half of all major bleeding events started after surgery and before the first dose of dabigatran etexilate. There were no major bleeding events reported after hospital discharge in the dabigatran etexilate groups.
