NEW YORK, NY -- (Marketwire) -- 02/11/13 --  LifeSci Advisors, LLC, a
leading provider of investment research and investor relations
services in the healthcare sector, today announced that it has
initiated coverage of Navidea Biopharmaceuticals, Inc. (NYSE MKT:
NAVB), a biopharmaceutical company focused on precision diagnostic
radiopharmaceuticals. In 2011 and 2012, Navidea engaged in strategic
business development activities and carved out a strategic niche
effectively transforming itself into a pure-play precision
diagnostics company with 4 late-stage products. 
Navidea's lead product is Lymphoseek, which is a potential
"First-in-Class" targeted imaging agent for lymphatic mapping.
Following positive results from the two Phase 3 studies that hit on
all endpoints, NEO3-05 and NEO3-09, Navidea filed the Lymphoseek NDA
that was subsequently accepted by FDA. At the end of 2012, the
Company filed a Lymphoseek MAA with the European EMA. In the US,
Lymphoseek has an upcoming PDUFA goal date of April 30, 2013, and if
accepted, Navidea and its marketing partner Cardinal Health, plan to
launch with 80 direct sales representatives and an additional 400
technical liaisons, which should be sufficient to reach ~65% of
direct customers and achieve 90-95% overall market penetration. We
estimate Lymphoseek to have a global market potential of $643M. 
"Effectively de-risking the Company's business model, Navidea has
in-licensed two late-stage assets, NAV4694 and NAV5001, for the
diagnosis Alzheimer's and Parkinson's disease, respectively," said
Andrew I. McDonald, Ph.D., Managing Director at LifeSci Advisors.
"NAV4694, which was licensed from AstraZeneca, is a Fluorine-18
labeled 'Best-in-Class' radiopharmaceutical candidate in development
as an aid in the diagnosis of patients with Alzheimer's disease.
NAV4694 binds to β-amyloid deposits in the brain in order to
help diagnose patients with Alzheimer's by way of PET imaging.
NAV5001, licensed from Alseres, is a patented, novel, small molecule
agent that binds to the dopamine transporter (DaT) on the cell
surface of dopaminergic neurons and is a potential 'Best-in-Class'
agent to be viewed via SPECT imaging to identify various regions in
the brain associated with Parkinson's disease." 
In a 38-page Initiation Report by LifeSci Advisors, the clinical,
regulatory, and commercial aspects of Navidea's 4 late-stage
diagnostic assets are discussed. NAV4694 has strong performance
characteristics (rapid equilibrium, favorable CNS uptake, high
signal-to-noise ratios, and low white matter background binding) and
a very tight performance correlation to the benchmark amyloid imaging
agent C-PiB. We expect Navidea to initiate the Phase 3 NAV4694
program in early 2013. We believe that NAV4694 may have a market
potential of $1B or more. If successful, NAV4694 could generate
similar interest from potential partners as Avid
Radiopharmaceuticals' Amyvid, which was bought by Lilly for a
potential $800M. Additionally, NAV5001 has demonstrated a high
affinity for DaT and rapid kinetics, which should add to its ability
to produce clean images quickly. To date, over 600 Parkinson's
disease subjects have been treated with NAV5001 and a Phase 3 trial
under an amended SPA should be initiated in the first half of 2013.
We estimate that NAV5001 has a market potential of $1-1.5B.
