Navidea Biopharmaceuticals Announces 2012 Annual Meeting Results

Navidea Biopharmaceuticals, Inc. (NYSE MKT: NAVB), a biopharmaceutical company focused on precision diagnostic radiopharmaceuticals, today announced the results of voting at its 2012 Annual Meeting of Stockholders (the Annual Meeting) held August 14, 2012.

At the Annual Meeting, Navidea’s stockholders:

Following the formal business portion of the Annual Meeting, Dr. Mark Pykett, Navidea President and CEO, and other members of the Navidea executive team made a series of presentations to stockholders in attendance at the Annual Meeting on topics including program updates for Lymphoseek, 4694, CFT and RIGScan, and other pipeline expansion activities.

The presentations included highlights on the following 2011-2012 milestone achievements including

At a meeting of the Board of Directors following the Annual Meeting, the Board completed a process to re-align its members into three classes of equal size. NYSE regulations require companies with classified Boards, such as Navidea, to maintain their classes of Directors in roughly equal numbers. To comply with this regulation, Dr. Peter Drake resigned from the Class of 2014 and was immediately re-appointed to the Board’s Class of 2015.

In conclusion, Dr. Pykett said: “We have made considerable progress on the basis of strong, consistent execution in advancing Navidea’s strategic objectives during this year, as demonstrated by the numerous milestones achieved. We look forward to our stockholders’ continued support as we continue to focus on developing and commercializing precision diagnostics that deliver the right treatment to the right patients at the right time.”

Lymphoseek is a proprietary radioactive tracing agent being developed for use in connection with gamma detection devices in pre-operative lymphoscintigraphy imaging and in a surgical procedure known as Intraoperative Lymphatic Mapping (ILM). Lymphoseek works by binding to a specific receptor found on the surface of dendritic cells and macrophages, which reside in high concentration in lymph nodes. This receptor-targeted property of Lymphoseek enables it to attach to and remain within first draining lymph nodes.

Two Phase 3 multi-center clinical trials for Lymphoseek in subjects with breast cancer or melanoma have been completed (NEO3-05 and NEO3-09; trial registration numbers NCT00671918 and NCT01106040, respectively). A third Phase 3 clinical study to evaluate the efficacy of Lymphoseek as a sentinel lymph node tracing agent in subjects with head and neck squamous cell carcinoma is currently ongoing (NEO3-06; trial registration number NCT00911326).

4694 is a Fluorine-18 labeled precision radiopharmaceutical candidate for use in the imaging and evaluation of patients with signs or symptoms of cognitive impairment such as Alzheimer’s disease (AD). It binds to Beta-amyloid deposits in the brain that can then be imaged in positron emission tomography (PET) scans. Amyloid plaque pathology is a required feature of AD diagnosis and the presence of amyloid pathology is a supportive feature for diagnosis of probable AD.

CFT is a patented, novel, small molecule radiopharmaceutical used with single photon emission computed tomography (SPECT) imaging to identify the status of specific regions in the brains of patients suspected of having Parkinson’s disease. The agent binds to the dopamine transporter (DAT) on the cell surface of dopaminergic neurons in the striatum and substantia nigra regions of the brain. Loss of these neurons is a widely recognized hallmark of Parkinson’s disease. CFT has been administered to more than 600 subjects in multi-phase clinical trials to date. Results from these clinical trials have demonstrated that CFT has high affinity for DAT and rapid kinetics which enable the generation of clean diagnostic images quickly, beginning within approximately 20 minutes after injection. In addition to its potential use as an aid in the differential diagnosis of Parkinson’s disease and movement disorders, CFT may also be useful in the diagnosis of Dementia with Lewy Bodies (DLB), which after Alzheimer’s disease, is one of the most common forms of dementia.

Navidea Biopharmaceuticals, Inc. (NYSE MKT: NAVB) is a biopharmaceutical company focused on the development and commercialization of precision diagnostics and radiopharmaceutical agents. Navidea is actively developing four radiopharmaceutical agent platforms – Lymphoseek, 4694, CFT and RIGScan – to help identify the presence and status of undetected disease and enable better diagnostic accuracy, clinical decision-making and ultimately patient care. Navidea’s strategy is to deliver superior growth and shareholder return by bringing to market novel radiopharmaceutical agents and advancing the Company’s pipeline through selective acquisitions, global partnering and commercialization efforts.
