DUBLIN, OH, June 15, 2020 (GLOBE NEWSWIRE) — Navidea Biopharmaceuticals, Inc. (NYSE American: NAVB) (“Navidea” or the “Company”), a company focused on the development of precision immunodiagnostic agents and immunotherapeutics, is pleased to announce full enrollment in its ongoing NAV3-31 Phase 2B study titled “Evaluation of the Precision and Sensitivity of Tilmanocept Uptake Value (TUV) on Tc99m Tilmanocept Planar Imaging”. All of the subjects have been enrolled in the three-arm trial, and the study is on track for the last patient to be screened, and evaluated by end of 2020.
The aim of this Phase 2B study is to evaluate the repeatability, reproducibility, and stability of Tc99m tilmanocept imaging in both healthy subjects (Arm 1) and in patients with active RA (Arm 2), as well as to assess the ability of Tc99m tilmanocept to provide an early indicator of efficacy of anti-tumor necrosis factor (“TNF”) alpha treatment in RA patients (Arm 3). The third arm mirrors Navidea’s Phase 3 study, which has been designed to provide data to understand the magnitude of the signal change that could potentially occur as patients receive therapy. Navidea has enrolled 38 subjects in each Arm (1 and 2), and has concluded with another 29 subjects in Arm 3. Subjects in Arm 3 will be followed up to a period of 24 weeks with regular imaging of Tc99m tilmanocept and clinical assessments at predetermined intervals from time of initiation of anti-TNF alpha. Interim results previously announced in this trial have provided supportive evidence for Navidea’s hypotheses that Tc99m tilmanocept imaging can potentially provide a robust, quantifiable imaging assessment of RA-involved joints that enable the early prediction for physicians to confirm the appropriate clinical response. Navidea remains on track to meet with the FDA to finalize the Phase 3 study design, and the Phase 2B trial will continue in parallel until completion. Michael Rosol, Chief Medical Officer for Navidea, said, “We are pleased that we were able to fully enroll the required patients in this trial and are on schedule through the current situation with COVID-19. I give full credit to everyone involved in this study for their accomplishments. The enrollment to date gives us encouragement that we will be able to hit the ground running with our planned Phase 3 study later this year.” Dr. Rosol continued, “As I have said before, we are excited that we are on track to potentially provide rheumatologists and those suffering with RA with a noninvasive, quantifiable, early indicator of whether or not an anti-TNF alpha treatment is working. This could bring enormous benefit to these patients by assisting physicians in putting them on the right course of treatment earlier than would otherwise be possible today.”Jed Latkin, Navidea’s Chief Executive Officer, said, “I am encouraged by the positive feedback we have been given by the physicians and collaborators involved in this transformational Phase 2B trial. We look forward to leveraging the momentum we have generated with NAV3-31 toward our planned NAV3-33 Phase 3 trial later this year.”RA is a chronic disease affecting over 1.3 million Americans and as much as 1% of the worldwide population1. If the product is successfully developed, Navidea would expect to play a major role in the management of RA patients worldwide.
