Portola Pharmaceuticals has gained US FDA approval for Bevyxxa, the first and only anticoagulant for Hospital and Extended Duration Prevention of Venous Thromboembolism (VTE) in Acutely Ill Medical Patients.

Bevyxxa, an oral, once-daily Factor Xa inhibitor, was granted a Fast Track designation and approved by the FDA under Priority Review.

It has been approved based on data from Portola’s pivotal Phase 3 APEX Study, which enrolled 7,513 patients at more than 450 clinical sites worldwide.

“Bevyxxa represents a major advance for the field of thrombosis. It is the first therapy to demonstrate a reduction in the incidence of VTE in these high-risk patients without a significant increase in major bleeding,” said C. Michael Gibson, M.D., APEX Executive Committee Member and Steering Committee Chairman, professor, Harvard Medical School and chairman of the PERFUSE Study Group.

Acutely ill medical patients are those hospitalised for serious medical conditions, including heart failure, stroke, infection and pulmonary disease. Because of their underlying disorder and immobilization, they are at increased risk of developing deep vein thrombosis (DVT) and pulmonary embolism (PE) blood clots.

In the G7 countries, an estimated 24 million acutely ill medical patients are hospitalized each year and are at risk of VTE, either while in the hospital or following discharge.

More than one million VTE events and 150,000 VTE-related deaths occur annually in acutely ill medical patients in the G7 countries, despite the standard use of injectable enoxaparin and other heparins in the hospital. More than half of VTE events occur after patients are discharged from the hospital.

No other anticoagulant, including enoxaparin or any of the marketed oral Factor Xa inhibitors, is approved for in-hospital and extended-duration VTE prophylaxis in acutely ill medical patients.

Portola expects to launch Bevyxxa between August and November 2017.
