“Clinicians often struggle with diagnosing neurodegenerative diseases such as Parkinsonian syndromes,” said Cornelia Reininger, MD, PhD, Navidea Senior Vice President and Chief Medical Officer. “The differential diagnoses of movement disorders and tremor are extensive, and the disorders often exhibit similarities, especially early in the initial clinical presentation. The data accumulated to date from NAV5001 clinical trials suggests that it may be an effective, well-tolerated imaging agent with high affinity for DAT and rapid kinetics which enable faster generation of clear images, and may assist physicians in reaching an accurate diagnosis. We are excited to begin this registration program focused on patients with emerging symptoms where diagnostic uncertainty and unmet need are highest. We believe that NAV5001 has the promise to address the needs of a rapidly growing market and will provide another option to the currently marketed diagnostic products and methods.”About NAV5001 Iodine-123 labeled NAV5001 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 and other forms of Parkinsonism. NAV5001 has been administered to more than 600 subjects in multi-phase clinical trials to date. Results from these clinical trials have demonstrated that NAV5001 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 Parkinsonian syndromes and movement disorders, NAV5001 may also be useful in the diagnosis of Dementia with Lewy Bodies (DLB), which is the second most common cause of progressive dementia after Alzheimer's disease.
About Parkinsonian Syndromes, Parkinson’s Disease and other movement disordersParkinsonian syndromes and movement disorders such as Essential Tremor represent a class of neurodegenerative diseases with important diagnostic needs. Parkinsonian syndromes (PS) are neurodegenerative disorders that affect a person’s ability to control movement and other muscle functions . Parkinson's Disease (PD) 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. The Parkinson’s Disease Foundation (PDF) estimates that up to 10 million people worldwide are living with PD, including 1 million people in the U.S. Approximately 60,000 new cases of PD are diagnosed in the U.S. each year. 1 The International Essential Tremor Foundation estimates that as many as 10 million people in the United States are afflicted by essential tremor. PD is commonly misdiagnosed or completely missed in clinical evaluations as symptoms are often attributed to the normal aging process. Essential tremor and the other similar conditions are also common sources of confusion in PD diagnosis. Collectively, there are over 25 million people in the U.S. and Europe with some type of movement disorder, comprising a large differential diagnosis population. About Navidea Biopharmaceuticals Inc. 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® (technetium 99m tilmanocept) Injection, NAV4694, NAV5001 and RIGScan TM – to help identify the sites and pathways of undetected disease and enable better diagnostic accuracy, clinical decision-making and, ultimately, patient care.
