– Differentiated Syk/JAK Inhibitor Studied in Patients with Heavily Pre-Treated T-Cell Malignancies –             

– Also Accepted: Two Posters on Andexxa® and an Oral Session on the Burden of Hospital Readmissions Due to Venous Thromboembolism Among Cancer Patients –

SOUTH SAN FRANCISCO, Calif., Nov. 01, 2018 (GLOBE NEWSWIRE) -- Portola Pharmaceuticals, Inc.® (Nasdaq: PTLA) today announced that new interim results from the Company’s ongoing Phase 2a study of cerdulatinib in patients with relapsed/refractory peripheral T-cell lymphoma (PTCL) and cutaneous T-cell lymphoma (CTCL), will be presented during an oral session at the 2018 American Society of Hematology (ASH) Annual Meeting, December 1-4, 2018 in San Diego, California. 

The Company also will present new outcomes-based research on the burden of hospital readmissions for venous thromboembolism among patients with cancer during an oral session on Sunday, December 2, and two investigator-initiated animal studies highlighting the anticoagulant reversal agent Andexxa [coagulation Factor Xa (recombinant), inactivated-zhzo] will be presented in poster sessions.

“As shown at the American Society of Clinical Oncology and European Hematology Association meetings earlier this year, cerdulatinib has shown encouraging results across a range of B- and T-cell malignancies and we look forward to presenting new data specifically focused on patients with PTCL and CTCL,” said John Curnutte, M.D., Ph.D., head of research and development for Portola. “These data also will serve as a basis for further discussions with regulatory agencies regarding the potential regulatory path forward for cerdulatinib in certain tumor subtypes.”

Cerdulatinib is an investigational oral, dual Syk/JAK kinase inhibitor that uniquely inhibits two key cell signaling pathways that promote cancer cell growth in certain hematologic malignancies. It is being developed for the treatment of resistant or relapsed hematologic cancer.
