Navidea Biopharmaceuticals, Inc. (NYSE MKT: NAVB), a biopharmaceutical company focused on precision diagnostic radiopharmaceuticals, today announced that it recently participated in a focused panel session at the 6th International Symposium on Metastasis in Head and Neck Cancer held in Marburg, Germany. Lymphoseek ® (technetium Tc 99m tilmanocept) Injection and initial clinical experience data from one site participating in the Lymphoseek head and neck cancer clinical trial, NEO3-06, were discussed during a satellite symposium focused on Sentinel Lymph Node (SLN) biopsy in Head and Neck Cancer. In this session, presentations were made by a panel of head and neck specialists which included Lymphoseek-related presentations from Navidea’s Chief Medical Officer, Cornelia Reininger, MD, PhD and Francisco J. Civantos, MD, FACS, Head & Neck / Skull Base Surgery, University of Miami. Lymphoseek is a receptor-targeted, small-molecule, investigational radiopharmaceutical used in lymphatic mapping procedures.
“It was enlightening for the delegates to understand more about sentinel node localization and the specific function of Lymphoseek. Following significant panel and expert discussion, it was agreed that sentinel node localization has a vital role in head and neck cancers and should be applied in routine clinical care,” Prof. John Buscombe, Head of the Department of Nuclear Medicine at Cambridge University Hospitals, Cambridge, UK commented. “However, current radioactive colloids often display variable performance and the limitation of being of human or animal origin. These data appear to indicate that lymphatic mapping procedures can be improved using an agent such as Lymphoseek which shows more accurate localization of the sentinel node or nodes and will lead to less aggressive surgery, more accurate staging of disease and fewer side effects.”
Professsor Buscombe acted as moderator for the session and described the history and technique of sentinel node localization and demonstrated that the technique was safe for the surgeons, their assistants and the pathologists. Dr. Reininger provided a summary of Lymphoseek’s performance advantages in lymphatic mapping of solid tumor cancers. Data demonstrated Lymphoseek’s rapid clearance from the injection site but stability in the sentinel node for up to 24 hours and reinforced its ability to accurately identify and map SLNs that can facilitate accurate staging and may potentially decrease some patients’ extent of surgery, thus reducing possible serious morbidity. Professor Civantos spoke of the University of Miami’s initial clinical experience with Lymphoseek. Results to date have demonstrated its utility, diagnostic predictive value and safety in patients, both preoperatively in lymphoscintigraphy and for intraoperative localization.
