Navidea Biopharmaceuticals Inc : Navidea Biopharmaceuticals Completes License for Parkinson's Disease Imaging Agent

Navidea Biopharmaceuticals, Inc. (NYSE MKT: NAVB), a biopharmaceutical company focused on precision diagnostic radiopharmaceuticals, today announced that it has entered into an agreement with Alseres Pharmaceuticals, Inc. (Alseres) to license [¹²³I]-E-IACFT Injection (CFT), an Iodine-123 radiolabeled imaging agent being developed as an aid in the diagnosis of Parkinson's disease and other movement disorders, with a potential use as a diagnostic aid in dementia.

"The diagnostic dilemma in movement disorders remains a pressing medical need that will continue to escalate as our world's population ages," said Dr. Mark Pykett, President and CEO of Navidea. "The addition of the CFT program is consistent with our growth strategy to build our precision radiopharmaceutical pipeline with later-stage, high-value diagnostics aimed at important medical needs."

"We believe that CFT has the potential to be a best-in-class imaging agent to improve diagnostic accuracy by differentiating Parkinson's disease from non-degenerative movement disorders, especially during the period soon after symptom-onset," said Dr. Thomas Tulip, Navidea' s EVP and Chief Business Officer. "This licensing agreement has afforded Navidea another strong Phase 3 diagnostic imaging asset that has great synergy with our AZD4694 imaging program, which we are developing as an aid in the diagnosis of Alzheimer's disease. These exciting programs provide us with a robust franchise in precision neuroimaging diagnostics."

"We are pleased to have completed this agreement with Navidea. With its focus, dedication, and imaging expertise, Navidea represents an ideal partner to complete the development and commercialization of this promising agent that may help millions of patients with movement disorders arrive at a more timely and accurate diagnosis," said Peter G. Savas, CEO of Alseres.

Under the terms of the license agreement, Alseres granted Navidea an exclusive, worldwide sub-license to research, develop and commercialize CFT. The final terms of the agreement call for Navidea to make a one-time sub-license execution payment to Alseres equal to (i) One Hundred Seventy-Five Thousand Dollars ($175,000) and (ii) issue Alseres 300,000 shares of NAVB common stock.

The license agreement also provides for contingent milestone payments of up to $2.9 million, $2.5 million of which will principally occur at the time of product registration or upon commercial sales, and the issuance of up to an additional 1.15 million shares of Navidea stock, 950,000 shares of which are issuable at the time of product registration or upon commercial sales. In addition, the license terms anticipate royalties on annual net sales of the approved product which are consistent with industry-standard terms and certain license extension fees, payable in cash and shares of common stock, in the event certain diligence milestones are not met. Navidea agreed to file with the Securities and Exchange Commission and use its best commercial efforts to have declared effective within 90 days a registration statement that would permit Alseres to resell the common stock issued as initial or milestone payments under the license agreement.

Management will be available to answer questions regarding the license agreement and the addition of this new radiopharmaceutical program to its pipeline during it Second Quarter Earnings conference call with the investment community on Tuesday, August 7, 2012 at 8:00 AM EDT.

About [¹²³I]-E-IACFT (CFT)

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.

About Parkinsonian Syndromes and Parkinson's Disease

Parkinsonian syndromes (PS) are neurodegenerative disorders that affect a person's ability to control movement and other muscle functions. Parkinson's Disease is the most common form of Parkinsonian Syndromes believed to be caused by loss of dopamine producing neurons in the brain and with first symptoms such as tremor, rigidity, or slow movement. Other less common Parkinsonian Syndromes include multiple system atrophy (MSA), Progressive Supranuclear Palsy (PSP), and drug-induced Parkinsonism. According to the Parkinson's Disease Foundation, approximately 60,000 Americans are diagnosed with Parkinson's disease each year, and this number does not reflect the thousands of cases that go undetected.¹
