Navidea Biopharmaceuticals Forms Macrophage Therapeutics Business Unit To Explore Therapeutic Applications Of Manocept
DUBLIN, Ohio--(BUSINESS WIRE)--Navidea Biopharmaceuticals (NYSE MKT: NAVB) announced today the formation of a new business unit, Macrophage Therapeutics, to further explore therapeutic applications for the Manocept™ platform. The Manocept platform serves as the molecular backbone of Navidea’s FDA-approved, activated macrophage-targeting agent, Lymphoseek® (technetium Tc 99m tilmanocept) injection. Preclinical data being developed by the Company using tilmanocept linked to various therapeutic agents suggest that tilmanocept’s binding affinity to CD206 receptors demonstrates the potential for this technology to be useful in treating diseases linked to the over-activation of macrophages. This includes various cancers as well as autoimmune, infectious, cardiovascular, and central nervous system diseases.
“Navidea’s primary focus remains the successful commercialization of Lymphoseek for use in sentinel lymph node detection and lymphatic mapping,” said Rick Gonzalez, Chief Executive Officer of Navidea. "However, given Manocept’s potential to be applied in the treatment of multiple diseases based on its unique targeting properties, we have formed this new business unit to pursue therapeutic development. The plan is to continue preclinical research, further assess therapeutic agents that may be paired with Manocept, and evaluate optimal indications and regulatory pathways to enable the most efficient path to market.”
Navidea intends to structure Macrophage Therapeutics such that it will remain under Navidea’s control enabling existing shareholders to capture potential future value, but also allow funding of future development in a standalone, non-dilutive manner to Navidea’s existing shareholders. Current board members Michael M. Goldberg, M.D. and Eric K. Rowinsky, M.D. and Navidea’s Chief Scientific Officer, Frederick O. Cope, Ph.D. have been appointed to focus on the launch of the new unit.
"Manocept has a unique and powerful ability to seek out macrophages that are overactive in the body," said Michael Goldberg, M.D. "Linking a radioisotope to illuminate the presence of disease, such as the case with the FDA-approved Lymphoseek, is just the beginning. Manocept may also be combined with well-characterized therapeutic agents designed to destroy unwanted macrophages. Based on preclinical data, we look forward to advancing Manocept-based therapeutics into clinical development.”
About Macrophage Therapeutics
Macrophage Therapeutics seeks to leverage Navidea’s FDA-approved diagnostic applications and patented Manocept™ platform as a delivery system to target activated macrophages and develop treatments for cancer, cardiovascular, autoimmune, inflammatory, infectious, and CNS diseases. Navidea’s Manocept platform is predicated on the ability to specifically target the CD206 mannose receptor expressed on activated macrophages. Macrophages play important roles in many disease states and are an emerging target in many disorders where diagnostic uncertainty exists. This flexible and versatile platform acts as an engine for purpose-built molecules that may enhance diagnostic accuracy and delivery of therapeutic agents. The Company’s FDA-approved precision diagnostic lymphatic mapping agent, Lymphoseek® (technetium Tc-99m tilmanocept) injection, is representative of the ability to successfully exploit this mechanism to develop powerful, new diagnostic and therapeutic agents.

Lymphoseek® Indication and Important Safety Information – U.S.
Lymphoseek is a radioactive diagnostic agent indicated with or without scintigraphic imaging for:
Lymphatic mapping using a handheld gamma counter to locate lymph nodes draining a primary tumor site in patients with solid tumors for which this procedure is a component of intraoperative management.
Guiding sentinel lymph node biopsy using a handheld gamma counter in patients with clinically node negative squamous cell carcinoma of the oral cavity, breast cancer or melanoma.
Important Safety Information
In clinical trials with Lymphoseek, no serious hypersensitivity reactions were reported, however Lymphoseek may pose a risk of such reactions due to its chemical similarity to dextran. Serious hypersensitivity reactions have been associated with dextran and modified forms of dextran (such as iron dextran drugs).
Prior to the administration of Lymphoseek, patients should be asked about previous hypersensitivity reactions to drugs, in particular dextran and modified forms of dextran. Resuscitation equipment and trained personnel should be available at the time of Lymphoseek administration, and patients observed for signs or symptoms of hypersensitivity following injection.
Any radiation-emitting product may increase the risk for cancer. Adhere to dose recommendations and ensure safe handling to minimize the risk for excessive radiation exposure to patients or health care workers. In clinical trials, no patients experienced serious adverse reactions and the most common adverse reactions were injection site irritation and/or pain (<1%).
