European Commission Approves Navidea’s Sentinel Lymph Node Detection Agent Lymphoseek®

Approval Sets the Stage for Revenue Generation through Targeted Launches in Europe

DUBLIN, Ohio--(BUSINESS WIRE)-- Navidea Biopharmaceuticals, Inc. (NYSE MKT:NAVB) has announced that the European Commission has granted marketing authorization for Lymphoseek® 250 micrograms kit for radiopharmaceutical preparation. Lymphoseek is now approved in the European Union (EU) for use in imaging and intraoperative detection of sentinel lymph nodes draining a primary tumor in adult patients with breast cancer, melanoma, or localized squamous cell carcinoma of the oral cavity.

“This is yet another important milestone achieved by Navidea in our global commercialization of Lymphoseek and reaffirms our commitment to improving the lives of oncology patients worldwide,” said Navidea CEO, Rick Gonzalez. “We are excited that Lymphoseek is the first agent centrally approved in Europe for Sentinel Lymph Node (SLN) detection. It is differentiated in its ability to reliably and accurately locate SLNs to effectively stage cancer and inform post-surgical treatment. We look forward to making Lymphoseek available throughout Europe with initial launches into certain major markets planned for later in 2015. We will be sharing more details about our commercialization plans in the coming months.”

“Lymphoseek can be a game changer in allowing more patients across Europe access to this technology which allows their cancer to be accurately staged without disfiguring and disabling surgery,” said John Buscombe, Physician in Nuclear Medicine, Addenbrooke’s Hospital, Cambridge, UK. “The availability and convenience of a receptor-targeted imaging agent such as Lymphoseek, the first synthetic and biotargeted agent for use in sentinel node localization, provides both the required diagnostic accuracy and reliability that enables a surgeon planning sentinel node biopsy to be able to operate without the concerns raised with timing from imaging to surgery found with alternate methods.”

The sentinel node detection label in Europe may now allow Lymphoseek to be used in approximately 367,000, 83,000 and 55,000 new cases of breast cancer, melanoma and oral cavity cancers diagnosed in Europe annually, respectively.

Lymphoseek is approved in the U.S. for use in lymphatic mapping to locate lymph nodes draining a primary tumor site in patients with solid tumors for which this procedure is a component of intraoperative management and for guiding Sentinel Lymph Node Biopsy (SLNB) using a handheld gamma counter in patients with node negative squamous cell carcinoma of the oral cavity, breast cancer or melanoma.

About Lymphoseek

Lymphoseek^® (technetium Tc 99m tilmanocept) injection is the first and only FDA-approved receptor-targeted lymphatic mapping agent. It is a novel, receptor-targeted, small-molecule radiopharmaceutical used in the evaluation of lymphatic basins that may have cancer involvement in patients. Lymphoseek is designed for the precise identification of lymph nodes that drain from a primary tumor, which have the highest probability of harboring cancer. Lymphoseek is approved by the U.S. Food and Drug Administration (FDA) for use in solid tumor cancers where lymphatic mapping is a component of surgical management and for guiding sentinel lymph node biopsy in patients with clinically node negative breast cancer, melanoma or squamous cell carcinoma of the oral cavity. Lymphoseek has also received European approval in imaging and intraoperative detection of sentinel lymph nodes in patients with melanoma, breast cancer or localized squamous cell carcinoma of the oral cavity.

Accurate diagnostic evaluation of cancer is critical, as it guides therapy decisions and determines patient prognosis and risk of recurrence. Overall in the U.S., solid tumor cancers may represent up to 1.2 million cases per year. The sentinel node label in the U.S. and Europe may address approximately 235,000 new cases of breast cancer, 76,000 new cases of melanoma and 45,000 new cases of head and neck/oral cancer in the U.S., and approximately 367,000 new cases of breast cancer, 83,000 new cases of melanoma and 55,000 new cases of head and neck/oral cancer diagnosed in Europe annually.

EU Lymphoseek® Indication and Important Safety Information

Radiolabelled Lymphoseek is indicated for imaging and intraoperative detection of sentinel lymph nodes draining a primary tumour in adult patients with breast cancer, melanoma, or localised squamous cell carcinoma of the oral cavity.

External imaging and intraoperative evaluation may be performed using a gamma detection device.

Important Safety Information about Lymphoseek for EU patients

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.

Any radiation-emitting product may increase the risk for cancer. Adhere to dose recommendations and ensure safe handling to minimize the risk for excessive radiation exposure to patients or health care workers.

In clinical trials, no patients experienced serious adverse reactions and the most common adverse reactions were injection site irritation and/or pain (<1%).
