About Portola Pharmaceuticals, Inc. [PTLA]: Portola is a biopharmaceutical company focused on the development and commercialization of novel therapeutics in the areas of thrombosis (blood clots), other hematologic disorders for patients who currently have limited or no approved treatment options. Portola's current development-stage portfolio consists of three compounds discovered through its internal research efforts and one discovered by Portola scientists during their time at a prior company.
Portola's two lead programs address significant unmet medical needs in the area of thrombosis.Portola's lead compound, betrixaban, is an investigational, novel, oral, once-daily inhibitor of Factor Xa in Phase 3 development for extended duration prophylaxis (preventive treatment) of a form of thrombosis known as venous thromboembolism (VTE) in acute medically ill patients. Currently, there is no anticoagulant approved for extended duration VTE prophylaxis in this population. Portola's second lead development candidate, andexanet alfa, is a recombinant protein designed to reverse the anticoagulant activity in patients treated with a Factor Xa inhibitor who suffer an uncontrolled bleeding episode or require emergency surgery. Portola has entered into collaboration agreements with Bristol-Myers Squibb Company and Pfizer Inc., with Bayer Pharma AG and Janssen Pharmaceuticals, Inc., and with Daiichi Sankyo to study andexanet alfa with Eliquis® (apixaban), XARELTO® (rivaroxaban) and edoxaban, respectively, in Portola's Phase 2 studies. Portola retains full, worldwide commercial rights with respect to andexanet alfa. Portola's third product candidate, PRT2070, is an orally available kinase inhibitor being developed for hematologic (blood) cancers and inflammatory disorders. PRT2070 inhibits spleen tyrosine kinase (Syk) and janus kinases (JAK), enzymes that regulate important signaling pathways. Portola plans to file an Investigational New Drug (IND) application in the third quarter of 2013and initiate a Phase 1/2 clinical study of PRT2070 in 2013 in patients with B-cell hematologic cancers who have failed or relapsed on existing marketed therapies or products in development, including patients with identified mutations. Portola's fourth program, PRT2607 and other highly selective Syk inhibitors, is partnered with Biogen Idec Inc.
