Navidea Biopharmaceuticals, Inc. (NYSE MKT: NAVB), a biopharmaceutical company focused on precision diagnostic radiopharmaceuticals, today announced that it has entered into an agreement with Nordion (Canada) Inc. to produce and supply I-labeled NAV5001 for Navidea’s late-phase clinical trials.

The agreement focuses on Nordion’s cGMP manufacturing and supply of NAV5001 clinical trial material to be produced at Nordion’s Vancouver, British Columbia, facility. Accordingly, Nordion will radiolabel Navidea’s precursor drug product with Iodine-123 to form [I]NAV5001, manage the logistics and make arrangements for shipment of NAV5001 to third-party clinical trial sites on behalf of Navidea. The agreement may serve as a predecessor to a commercial supply arrangement in the future.

“This manufacturing and supply agreement with Nordion moves us closer to commencing our critical NAV5001 clinical programs in the differential diagnosis of Parkinsonian Syndromes and Dementia with Lewy Bodies,” stated Thomas Tulip, PhD, Navidea’s President and Chief Business Officer. “Nordion has extensive expertise in high quality production of I radiopharmaceuticals and a world class distribution system to reliably manage logistics to ensure that radiolabeled NAV5001 reaches clinical trial site destinations according to rigorous standards.”

“We are proud that Navidea has chosen Nordion manufacturing and distribution services for one of its important neurological radiopharmaceuticals,” said Tom Burnett, General Manager, Medical Isotopes, Nordion. “We offer a strong base of technical expertise, production and distribution services that we expect will enable Navidea to efficiently provide their investigational product candidate to doctors and medical centers involved in NAV5001 clinical trials throughout North America.”

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 DLB, which after Alzheimer’s disease, is one of the most common forms of dementia.
