The approval of Lymphoseek is based on data from more than 540 subjects receiving Lymphoseek. In pivotal Phase 3 studies that were conducted in 332 patients with either breast cancer or melanoma, Lymphoseek, on average, was present in 97% (range 94-100%) of resected, histology-confirmed lymph nodes. To date, no clinically significant drug-related adverse reactions have been reported. Lymphoseek has no contraindications and the most common adverse reactions were injection site irritation and/or pain (<1%).“We believe today’s approval of Lymphoseek validates our ability to advance the field of precision diagnostics,” said Mark J. Pykett, V.M.D., Ph.D., President and CEO of Navidea. “Our vision is to improve diagnostic accuracy, clinical decision-making and patient care. We are gratified that our scientific achievements may benefit thousands of patients diagnosed with breast cancer and melanoma each year. We look forward to continuing the development of Lymphoseek into additional indications and to progressing our oncology and neurology pipeline.” Lymphoseek will be sold and distributed in the U.S. on an exclusive basis by Cardinal Health, Inc. As part of the distribution agreement, Cardinal Health’s Nuclear Pharmacy Services business will be responsible for commercializing and dispensing Lymphoseek to health care professionals who are involved in lymphatic mapping. Navidea is also working to identify and partner with distributors in other markets outside of the U.S. Navidea will play an ongoing role in commercial activities through focused deployment of medical science liaison and medical education activities. This is consistent with Navidea’s overall strategy to remain involved in market-based activities with its products while leveraging the extensive capabilities and infrastructure of partners around the world. Conference Call for Investors Navidea Biopharmaceuticals will host a conference call for investors, today at 4:00 p.m. EDT to discuss FDA’s approval of Lymphoseek. Conference call dial-in details will be announced this afternoon. About Lymphoseek ® Lymphoseek ® (technetium Tc 99m tilmanocept) Injection is a novel, receptor-targeted, small-molecule radiopharmaceutical used in lymphatic mapping procedures that are performed to help stage breast cancer and melanoma. Lymphoseek is designed to identify the lymph nodes that drain from a primary tumor, which have the highest probability of harboring cancer, in patients with breast cancer or melanoma. Lymphatic mapping is a procedure in which lymph nodes that may contain tumor metastases are identified and biopsied to determine if cancer has spread beyond the primary tumor. Accurate staging of cancer is critical, as it guides therapy decisions and determines patient prognosis and risk of recurrence. Lymphoseek was approved for use by the FDA on March 13, 2013. According to the American Cancer Society, approximately 232,000 new cases of breast cancer and 77,000 new cases of melanoma are expected to be diagnosed in the United States in 2013.
About Lymphatic MappingLymphatic mapping is a procedure designed to guide lymph node dissection and biopsy procedures. It consists of Intraoperative Lymphatic Mapping (ILM) often accompanied by lymphoscintigraphy. Lymphoscintigraphy is an imaging procedure routinely performed pre-operatively to provide guidance on the location of lymph nodes to be biopsied. ILM is a surgical procedure in which lymph nodes draining the area around a tumor are identified and biopsied to determine if cancer has spread to the lymph nodes. These nodes, commonly referred to as “Sentinel Lymph Nodes,” are removed and analyzed for the presence of malignant cells. Lymphatic Mapping provides an accurate staging procedure that can help ensure optimal surgical and therapeutic choices, including the avoidance of the morbidity of a complete lymph node dissection for patients in whom the Sentinel Lymph Nodes were found to be free of cancer. Indication and Important Safety Information About Lymphoseek Indication Lymphoseek (technetium Tc 99m tilmanocept) Injection is indicated for lymphatic mapping with a hand-held gamma counter to assist in the localization of lymph nodes draining a primary tumor site in patients with breast cancer or melanoma. Important Safety Information In clinical trials with Lymphoseek, no serious hypersensitivity reactions were reported, however Lymphoseek may pose a risk of such reactions due to its chemical similarity to dextran. Serious hypersensitivity reactions have been associated with dextran and modified forms of dextran (such as iron dextran drugs). Prior to the administration of Lymphoseek, patients should be asked about previous hypersensitivity reactions to drugs, in particular dextran and modified forms of dextran. Resuscitation equipment and trained personnel should be available at the time of Lymphoseek administration, and patients observed for signs or symptoms of hypersensitivity following injection. The most common adverse reactions are injection site irritation and/or pain (<1%). FULL LYMPHOSEEK PRESCRIBING INFORMATION CAN BE FOUND AT: WWW.LYMPHOSEEK.COM About Navidea Biopharmaceuticals, Inc.
