Navidea Biopharmaceuticals Announces Acceptance of Abstract for Presentation at the Tumor Myeloid-Directed Therapies Summit Annual Meeting

Navidea Biopharmaceuticals, Inc. (NYSE American: NAVB) ("Navidea" or the "Company"), a company focused on the development of precision immunodiagnostic agents and immunotherapeutics, today announced acceptance of its abstract titled, "CD206 Targeted Delivery of Bisphosphonate Payloads Alter Human Macrophage Phenotypes Towards M1-like" for presentation of a poster at this year's Tumor Myeloid-Directed Therapies Summit.

The 2nd annual Tumor Myeloid-Directed Therapies Summit meeting will be held June 14-16, 2022 in Boston, MA. The presentation will take place Tuesday, June 14. Meeting information can be found on the conference website (https://tumor-myeloid-therapeutics.com).

The poster will present information related to the synthesis of two novel bisphosphonate drugs that have been attached to Navidea's CD206-targeted drug delivery platform molecule, Manocept. These constructs use a novel degradable linker to release the therapy only once they have been internalized into a CD206-expressing cell, such as a tumor associated macrophage. The new therapeutic constructs were evaluated in human macrophage cell culture assays to compare the ability of the new constructs with unbound free therapy to shift the phenotype of macrophages toward a proinflammatory gene expression pattern. The new drug delivery constructs successfully shifted the phenotypes of human macrophages towards a proinflammatory state and compared favorably to the unbound free therapy. The new drug constructs also induced a highly significant reduction in macrophage expression of signal regulatory protein alpha ("SIRP?"), the receptor for the "don't eat me" signal that, when activated, suppresses the ability of macrophages to attack and phagocytize disease associated cells such as cancer cells. The ability to induce this type of phenotypic change in macrophages could have far-reaching applications in cancer immunotherapy.

Dr. Michael Rosol, Chief Medical Officer for Navidea, said, "These new therapeutic constructs demonstrate the power of our adaptable platform technology to deliver a wide array of small molecule payloads in a targeted fashion to macrophages involved in the propagation of a variety of severe illnesses including cancer."
