Navidea Biopharmaceuticals Signs Letter of Intent with WorldCare Clinical to Partner on Navidea’s Rheumatoid Arthritis Clinical Imaging Workflow and Commercialization; Other Business Updates

Navidea Biopharmaceuticals, Inc. (NYSE American: NAVB) ("Navidea" or the "Company"), a company focused on the development of precision immunodiagnostic agents and immunotherapeutics, today announced that it has signed a letter of intent ("LOI") to partner with WorldCare Clinical, LLC for the Company’s rheumatoid arthritis ("RA") diagnostic clinical imaging workflow. Per the agreement, WorldCare would serve as Navidea’s central imaging service provider following FDA approval of Navidea’s RA diagnostic. WorldCare Clinical is the world’s leading independent contract research organization dedicated to imaging in clinical trials and brings with it over 25 years of clinical trial imaging, commercial clinical imaging, and large-scale data management experience.

WorldCare and Navidea will work in conjunction during the completion of Navidea’s ongoing and planned RA diagnostic trials. The partnership will work to develop the commercial workflow and infrastructure to support the full-scale commercialization plan for Navidea’s RA diagnostic. It is anticipated that WorldCare will be the vendor managing the imaging aspects of the upcoming Phase 2b (NAV3-32) and Phase 3 (NAV3-33) clinical trials, and will work in parallel to develop an optimized workflow in preparation for commercial launch in indications in RA.

Jed Latkin, Chief Executive Officer of Navidea, said, "We are extremely pleased to partner with a world-class imaging vendor in this necessary component of our RA diagnostic workflow. As we near the Phase 3 clinical trial, we continue discussions with commercial partners, and will provide an update on developments on that front in the near future."

Dr. Michael Rosol, Chief Medical Officer of Navidea, said, "We are excited to have this agreement in place and to select WorldCare Clinical as our imaging partner for the upcoming trials in RA. WorldCare will provide the central imaging reads that will be integral to the clinical and commercial success of Tc 99m tilmanocept in RA monitoring applications. The reach and experience that they bring to the table in managing imaging workflows in clinical trials and in the clinic has convinced us that they are the right partner for Navidea at this pivotal stage in development."

Aaron Timm, Chief Executive Officer of WorldCare Clinical, said, "We are excited to partner with the Navidea team on their upcoming RA trials as well in the use of Tc 99m tilmanocept in RA monitoring applications. We believe that our radiological, scientific, and operational expertise will contribute to Navidea’s goal of enhancing patient care by enabling better diagnostic accuracy, clinical decision-making, and targeted treatment."
