SAN RAMON, Calif., Sept. 12, 2016 (GLOBE NEWSWIRE) -- Galena Biopharma, Inc. (NASDAQ:GALE), a biopharmaceutical company committed to the development and commercialization of hematology and oncology therapeutics that address unmet medical needs, today announced the issuance of a second Japanese Patent (JP Patent #5985719) containing composition and method of use claims for GALE-401, the Company’s controlled release version of anagrelide. The patent covers the treatment of patients suffering from myeloproliferative diseases, including myeloproliferative neoplasms (MPNs) such as essential thrombocythemia (ET) and polycythemia vera. The patent provides GALE-401 exclusivity until 2029, not including any patent term extensions.
“With our plans to initiate a Phase 3 trial next year in essential thrombocythemia, we are looking to position GALE-401 as a potential treatment option for MPN patients worldwide,” said Mark W. Schwartz, Ph.D., President and Chief Executive Officer. “This Japanese patent further expands our international intellectual property (IP) position complementing our IP estate in the United States. Branded anagrelide immediate release was approved in Japan in 2014.
GALE-401 contains the active ingredient anagrelide. The currently available immediate release formulation (Agrylin® or anagrelide IR) is approved in the U.S., Europe and Japan for the treatment of patients with thrombocythemia, secondary to myeloproliferative disorders, to reduce the elevated platelet count and the risk of thrombosis, and to ameliorate associated symptoms including thrombo-hemorrhagic events. Adverse events associated with anagrelide IR, such as nausea, diarrhea, abdominal pain, palpitations, tachycardia, and headache, may be dose and plasma concentration dependent. GALE-401 is a controlled release formulation of anagrelide, which significantly reduces the maximum plasma concentration (Cmax), and is expected to reduce side effects, but preserve efficacy. A Phase 2 pilot study with GALE-401 has been completed and Galena expects to launch a Phase 3 trial in the first half of 2017.
About Myeloproliferative Neoplasms and Essential Thrombocythemia
Myeloproliferative neoplasms (MPNs) are a closely related group of progressive blood cancers in which the bone marrow typically overproduces one of the mature blood elements. Other shared features include tendencies toward blood clotting/bleeding, organ enlargement, bone marrow scarring (fibrosis) and a possibility of transformation. The main MPNs are polycythemia vera (PV), chronic myelogenous leukemia (CML), primary myelofibrosis (PMF), and essential thrombocythemia (ET), all of which are associated with high platelet counts. The MPNs are progressive blood cancers that can strike anyone at any age, and for which there is no known cure.
Thrombocythemia is a myeloproliferative blood disorder. It is characterized by the production of too many platelets in the bone marrow. Too many platelets make normal clotting of blood difficult. It can be either reactive or primary (also termed essential and caused by a myeloproliferative disease). Primary Thrombocytosis (essential thrombocythemia or ET) is due to a failure to regulate the production of platelets (autonomous production) and is a feature of a number of myeloproliferative disorders. About a third of patients are asymptomatic at the time of diagnosis.
