DUBLIN, Ohio–(BUSINESS WIRE)–Navidea Biopharmaceuticals, Inc. (NYSE American: NAVB) (�Navidea” or the “Company”), a company focused on the development of precision immunodiagnostic agents and immunotherapeutics, today announced the regulatory approval of Lymphoaim (“Lymphoseek” in the rest of the world; Tc99m tilmanocept) by the Central Drugs Standard Control Organisation, India.

Tc99m tilmanocept is approved for imaging and intraoperative detection of sentinel lymph nodes draining a primary tumor in adult patients with breast cancer, melanoma, or localized squamous cell carcinoma of the oral cavity. External imaging and intraoperative evaluation may be performed using a gamma detection device.

Dr. Michael Rosol, Chief Medical Officer for Navidea, said, “We are delighted that Lymphoaim has received regulatory approval in India and will be available to patients in need.” Dr. Rosol continued, “This will also bring a new revenue stream to the Company to help us advance other pipeline products.”

Mr. Shukrit Sudhir Chimote, Chief Executive Officer for Sayre, said, “Lymphoaim, a radioactive diagnostic agent, would benefit surgeons in guiding sentinel lymph node biopsies. This product fits well with Sayre’s mission of providing novel treatment solutions, and will certainly help boost our presence in the surgical oncology segment.”
