NEW YORK, Jan. 22, 2013 (GLOBE NEWSWIRE) -- NeoStem, Inc. (NYSE MKT:NBS) today announced the expansion of intellectual property protection around its lead product candidate, AMR-001, with the grant of U.S. patent number 8,343,485 entitled "Compositions and methods of Vascular Injury Repair." This is the third U.S. granted patent for AMR-001, protecting further expansion of its CD34+ chemotactic stem cell product composition claim as well as method of sourcing and administration of cells claims. Dr. Andrew L. Pecora, Chief Medical Officer of NeoStem, commented, "NeoStem's intellectual property portfolio around its phase 2 stem cell compound continues to expand in critical ways. With the grants of its last three U.S. patents, AMR-001 now enjoys greater protection in terms of its CD34 cell content and the indications for its use, which include treating any vascular injury caused by vascular insufficiency, covering CD34 stem cells sourced from bone marrow or peripheral blood and administered parenterally into an artery, vein or muscle." "This successful expansion of NeoStem's intellectual property improves our ability to protect our most mature clinical asset," said Dr. Robin L. Smith, Chairman and CEO of NeoStem. "We believe the IP around AMR-001, our stem cell therapy, is strong and broad and we continue to pursue incremental protection with no fewer than 30 additional patents pending around the world."
