Navidea Biopharmaceuticals Announces the Presentation of Lymphoseek® Data at Joint International Oncology Congress (JIOC)

Six presentations and sponsored lymphatic mapping symposium highlight results from Lymphoseek® clinical trials

DUBLIN, Ohio--(BUSINESS WIRE)-- Navidea Biopharmaceuticals, Inc. (NYSE MKT: NAVB), a biopharmaceutical company focused on precision diagnostic radiopharmaceuticals, today announced that data from its Lymphoseek® (technetium Tc 99m tilmanocept) Injection studies in patients with breast cancer, melanoma or head and neck cancer are being presented at the Joint International Oncology Congress (JIOC) from May 27-29, 2013 in San Francisco, CA. In addition to six oral and poster presentations focusing on important Lymphoseek technical and comparative performance characteristics, Navidea is sponsoring an educational symposium during the conference entitled, “Charting the Course: New Advances in Lymphatic Mapping” featuring presentations by five highly-respected key opinion leaders in the area of lymphatic mapping.

“We are honored by the opportunity to showcase our many peer-reviewed presentations at JIOC given its renowned international faculty of leading experts in the field of lymphatic mapping and oncology,” said Dr. Thomas Tulip, President and Chief Business Officer of Navidea. “These activities are part of our strategy to build global awareness for Lymphoseek following the recent U.S. approval and launch as we gain commercial momentum domestically and anticipate approval of the Marketing Authorization Application by the European Medicines Agency later this year. We continue our efforts to broaden and expedite access to Lymphoseek in other parts of the world, and having advanced to letters of intent with potential partners in substantial international markets, we hope to announce the execution of new commercialization agreements in the near future.”

“The presentations and posters at JIOC by Navidea and our collaborators provide notable insights into key attributes of the Lymphoseek product and franchise. The data presented demonstrate the comparative performance of Lymphoseek to non-receptor targeted colloidal materials used in lymphatic mapping in the U.S. and Europe, and the excellent localization of Lymphoseek in tumor-positive sentinel nodes in intraoral squamous cell carcinoma,” said Dr. Mark Pykett, CEO of Navidea. "We believe these data enhance the understanding and scope of Lymphoseek utilization as we continue to drive the science and value of this important agent, and may afford new opportunities to capitalize on its unique mechanism of action."

Details of the symposium, oral and poster presentations are listed below.

Presentation & Poster Title:

About Lymphoseek®

Lymphoseek® (technetium Tc 99m tilmanocept) Injection is a novel, receptor-targeted, small-molecule radiopharmaceutical used in lymphatic mapping procedures that are performed to help in the diagnostic evaluation of potential cancer spread for patients with breast cancer and melanoma. Lymphoseek is designed to identify the lymph nodes that drain from a primary tumor, which have the highest probability of harboring cancer. Lymphoseek was approved by the U.S. Food and Drug Administration in March, 2013 for use in lymphatic mapping to assist in the localization of lymph nodes draining a primary tumor in patients with breast cancer or melanoma. The Company anticipates continuing development of Lymphoseek into other solid tumor areas that may include head and neck cancers, prostate cancer, thyroid cancer, lung/bronchus cancers, colorectal cancer and others.

Accurate diagnostic evaluation of cancer is critical, as it guides therapy decisions and determines patient prognosis and risk of recurrence. According to the American Cancer Society, approximately 232,000 new cases of breast cancer, 77,000 new cases of melanoma and 67,000 new cases of head and neck/oral cancer are expected to be diagnosed in the United States in 2013.
