DUBLIN, Ohio--(BUSINESS WIRE)-- Navidea Biopharmaceuticals, Inc. (NYSE MKT: NAVB), a company focused on the development of precision immunodiagnostic agents and immunotherapeutics, today announced the execution of a non-binding letter of intent with Cerveau Technologies, Inc. (Cerveau) sublicensing the worldwide rights to conduct research using NAV4694, a beta-amyloid imaging agent being evaluated as an aid in the differential diagnosis of early-onset Alzheimer’s disease, as well as an exclusive license for the development and commercialization of NAV4694 in Australia, Canada, China, and Singapore. Cerveau is focused on enhancing access to key technologies to advance and improve brain health.

The non-binding term sheet outlines a potential agreement between the parties to sublicense NAV4694 to Cerveau in return for negotiated consideration. The letter of intent includes a provision that will lead to the dismissal of the litigation without prejudice initiated by Sinotau against Navidea if Navidea and Cerveau execute a definitive agreement.

Detailed financial terms of the agreement remain undisclosed until a definitive agreement is reached.

About NAV4694

NAV4694 is a Fluorine-18 labeled precision radiopharmaceutical candidate intended for use in Positron Emission Tomography (PET) imaging and evaluation of patients with signs or symptoms of cognitive impairment such as Alzheimer’s disease (AD). NAV4694 binds to beta-amyloid deposits in the brain that can then be imaged in scans. Beta-amyloid plaque pathology is widely used in the diagnosis of AD. The ability of NAV4694 imaging to display amyloid plaque pathology may enable earlier identification of AD and improve monitoring of disease progression and interpretation of brain scan images. There is an ongoing NAV4694 Phase 2b trial in Mild Cognitive Impairment and a Phase 3 program for NAV4694 in AD.
