Navidea Biopharmaceuticals, Inc. (NYSE MKT: NAVB), a biopharmaceutical company focused on precision diagnostic radiopharmaceuticals, announced today that it has submitted a Supplemental New Drug Application (sNDA) with the U.S. Food and Drug Administration (FDA) seeking approval for the marketing and sale of Lymphoseek
(technetium 99m tilmanocept) Injection for sentinel lymph node (SLN) detection in patients with head and neck cancer, an indication for which Lymphoseek was also granted Fast Track designation earlier this month. Lymphoseek is currently approved for use in lymphatic mapping procedures that are performed to aid in the diagnostic evaluation of potential cancer spread for patients with breast cancer and melanoma.
"Our sNDA submission for Lymphoseek is an important step toward Navidea’s goal of helping this patient population who generally face extensive surgery to properly stage their cancer," said Mark Pykett, VMD, PhD, Navidea CEO. "The filing follows the FDA approval and US launch of Lymphoseek for use in lymphatic mapping procedures that are performed to aid in the diagnostic evaluation of potential cancer spread in patients with breast cancer and melanoma. If this sNDA is approved, Lymphoseek will be the only approved agent for SLN detection in this patient population, and representing another step forward in Navidea’s efforts to develop precision diagnostics that improve the accuracy of diagnosis."
“Identification of sentinel lymph nodes in selected patients with head and neck cancer represents an important unmet need. Today, many patients may undergo unnecessary full regional lymph node dissection, which removes an entire chain of lymph nodes, in order to see if cancer has spread from the primary tumor into the lymphatic system. These surgeries are lengthy, costly and may often be associated with considerable morbidity and potential long-term side effects for the patient,” commented Dr. Stephen Y. Lai, MD, PhD, FACS, Associate Professor, Department of Head and Neck Surgery, The University of Texas MD Anderson Cancer Center and a lead investigator on the NEO3-06 Head and Neck Phase 3 clinical trial. “Unfortunately, there are no approved imaging agents available today to minimize this surgery and its morbidity, while identifying and removing only the key predictive lymph nodes. The ability of Lymphoseek to accurately identify sentinel lymph nodes in these patients, such as demonstrated in the NEO3-06 Phase 3 study, may not only improve diagnostic accuracy, but also make the procedure more efficient and minimize the morbidity and side effects associated with more extensive regional dissections.”
