Navidea Announces Data Presentations at 2013 Annual Meeting of the Society of Nuclear Medicine and Molecular Imaging (SNMMI)

Fourteen presentations highlight results from Lymphoseek®and NAV4694 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 and NAV4694 studies are being presented at the 2013 Annual Meeting of the Society of Nuclear Medicine and Molecular Imaging (SNMMI) to be held June 8-12, 2013 in Vancouver, Canada. In addition to the ten oral and poster presentations highlighting both the comparative performance of Lymphoseek against commonly-used non-receptor targeted colloidal materials as well as the results demonstrating the efficacy of lymphatic mapping in breast, melanoma and head and neck cancers, there will also be four oral and poster presentations focused on Navidea's β-amyloid PET imaging agent, NAV4694, that will reveal performance and comparative results from clinical studies in Alzheimer's disease.


"We are honored to have these data showcased at the world's premier educational and networking event for molecular imaging and nuclear medicine. These peer-reviewed presentations represent the growing body of clinical experience supporting both our recently launched lymphatic mapping agent, Lymphoseek, and the potential of NAV4694 as a diagnostic aid in Alzheimer's disease and cognitive impairment," said Dr. Mark Pykett, CEO of Navidea. "We are proud to have what we believe is the deepest late-stage radiopharmaceutical pipeline in the industry and remain committed to developing precision diagnostics that help identify the presence and status of disease enabling better diagnostic accuracy, clinical decision-making and ultimately patient care."

Notable data from Navidea and its collaborators being presented at SNMMI 2013 include:

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.

About NAV4694

NAV4694 is a Fluorine-18 labeled precision radiopharmaceutical candidate intended for use in Positron Emission Tomography (PET) imaging and evaluation of patients with signs or symptoms of cognitive impairment such as Alzheimer's disease (AD). NAV4694 binds to β-Amyloid deposits in the brain that can then be imaged in scans. β-Amyloid plaque pathology is widely used in the diagnosis of AD. The ability of NAV4694 imaging to display amyloid plaque pathology may enable earlier identification of AD and improve monitoring of disease progression and interpretation of brain scan images. Navidea plans for a Phase 3 trial of NAV4694 to begin in 2013.

AD is a progressive and fatal neurodegenerative disease. β-Amyloid imaging has the potential to play an increasingly important role in clinical practice as revised criteria for the diagnosis of probable AD allow for earlier diagnosis and therapeutic intervention. Alzheimer's Disease International estimated in 2010 that there were 36 million people living with all forms of dementia including AD.
