Portola Pharmaceuticals Announces Betrixaban and AndexXa™ (andexanet alfa) Presentations at ACC.17

SOUTH SAN FRANCISCO, Calif., March 07, 2017 (GLOBE NEWSWIRE) -- Portola Pharmaceuticals Inc.® (Nasdaq:PTLA) today announced that new data from the pivotal Phase 3 APEX Study of the Company’s investigational drug betrixaban will be presented in a poster session at the upcoming American College of Cardiology’s (ACC) 66th Annual Scientific Session & Expo, which is taking place from March 17-19 at the Walter E. Washington Convention Center in Washington, D.C. Additionally, clinical data on betrixaban and on the Company’s investigational agent AndexXa™ (andexanet alfa) will be discussed during an oral session titled, “Challenging the Standard of Care: Emerging Concepts in VTE Treatment and Prevention.”

Betrixaban, which has Fast Track designation from the U.S. Food and Drug Administration (FDA), is an oral, once-daily Factor Xa inhibitor anticoagulant in development for the extended prophylaxis of venous thromboembolism (VTE) in acute medically ill patients with risk factors for VTE. AndexXa, a U.S. Food and Drug Administration (FDA)-designated Breakthrough Therapy, is in development for patients treated with a direct (apixaban, rivaroxaban or edoxaban) or indirect (enoxaparin) Factor Xa inhibitor when reversal of anticoagulation is needed due to life-threatening or uncontrolled bleeding.

The betrixaban poster will include additional data that is not available in the abstract, which is currently available on the ACC website.
