Navidea’s Lymphoseek(R) Recommended by CHMP for European Approval in Sentinel Lymph Node Detection for Melanoma, Breast and Certain Head and Neck CancersFollowing European Commission authorization, Lymphoseek (technetium Tc 99m tilmanocept) Injection will be the first approved Sentinel Lymph Node detection agent in the EU
DUBLIN, Ohio--(Healthcare Sales & Marketing Network)--Navidea Biopharmaceuticals, Inc. (NYSE MKT: NAVB) has announced that that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has adopted a positive opinion recommending the granting of marketing authorization for Lymphoseek® 250 micrograms kit for radiopharmaceutical preparation (tilmanocept) in the European Union (EU). The recommendation is for Lymphoseek use in imaging and intraoperative detection of sentinel lymph nodes draining a primary tumor in adult patients with breast cancer, melanoma, or head and neck oral cavity squamous cell carcinoma.
The CHMP's positive recommendation will be reviewed by the European Commission, which has the authority to approve medicinal products for use in the 28 countries of the European Union and generally follows the recommendations of the CHMP. Navidea expects the European Commission to issue its final decision on the marketing authorization for Lymphoseek later this year.
"This positive CHMP opinion moves Lymphoseek closer to becoming the first and only sentinel lymph node detection agent approved in all 28 member countries of European Union,” said Michael Goldberg, M.D., Interim CEO of Navidea. "We believe Lymphoseek is differentiated in its ability to reliably and accurately locate sentinel lymph nodes draining a tumor, to help more effectively stage cancer and inform post-surgical treatment, and to decrease patient morbidity. We are increasingly excited by the global opportunity for Lymphoseek as we build upon our approval in the U.S. and prepare to make the product available next year to physicians in Europe looking to provide the best care for their patients.”
“Current medical practices for Head and Neck Cancers call for removal of large numbers of lymph nodes, lymph node dissection, even in patients without proven lymph node metastasis,” said Professor Remco de Bree, M.D., Ph.D., Department of Otolaryngology-Head and Neck Surgery, VU University Medical Center, Amsterdam, The Netherlands. “Using the common practice of elective treatment of the neck, large numbers of patients undergo unnecessary extensive surgical procedures, which are associated with the risk of decreased shoulder function, decreased quality of life and increased costs. The practice of Sentinel Lymph Node Biopsy (SLNB) may offer a less invasive and equally predictive alternative for patient staging and directing adequate treatment of the neck. We welcome the addition of Lymphoseek in Europe as an approved sentinel lymph node detection agent with the potential to offer surgeons the ability to reliably and accurately guide SLNB procedures.”
The opinion of the CHMP was based on positive and consistent results from Lymphoseek’s three pivotal prospective Phase 3 studies in melanoma, breast cancer, and certain Head and Neck Cancers and included associated analysis of the combined data from more than 500 subjects. All three studies showed positive diagnostic performance of Lymphoseek across the solid tumor types studied. 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%).
Lymphoseek is approved in the U.S. by the U.S. Food and Drug Administration (FDA) for use in lymphatic mapping to assist in the detection of tumor-draining lymph nodes in patients with breast cancer or melanoma and for use in guiding sentinel lymph node biopsy in certain oral cancer patients. Lymphoseek is also the subject of a supplemental New Drug Application (sNDA) currently under review by the FDA, related to broader and more flexible utilization in lymphatic mapping procedures.
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 with breast cancer, melanoma and Head and Neck Cancer patients with oral cavity carcinoma. 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 lymphatic mapping to assist in the localization of lymph nodes draining a primary tumor in patients with breast cancer or melanoma and for use in guiding sentinel lymph node biopsy in Head and Neck Cancer patients with squamous cell carcinoma of the oral cavity. The Company anticipates continuing development of Lymphoseek into other solid tumor areas.
Accurate diagnostic evaluation of cancer is critical, as it guides therapy decisions and determines patient prognosis and risk of recurrence. According to publicly available information, 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 are expected to be diagnosed in the United States in 2014, 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.
Lymphoseek Indication and Important Safety Information in the United States
Lymphoseek (technetium Tc 99m tilmanocept) Injection is indicated, using a hand-held gamma counter, for:
- Lymphatic mapping to assist in the localization of lymph nodes draining a primary tumor site in patients with breast cancer or melanoma;
- Guiding sentinel lymph node biopsy, in patients with clinically node negative squamous cell carcinoma (SCC) of the oral cavity.
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%).
