AMSTERDAM, June 12, 2017 /PRNewswire/ --

Norgine B.V. today announces the launch of LYMPHOSEEK^® (technetium Tc 99m tilmanocept) in Denmark, the Netherlands and the UK. LYMPHOSEEK^® is a 'next generation' radiopharmaceutical which, when used in sentinel lymph node biopsy (SLNB), represents a significant alternative to the current method of identifying sentinel lymph nodes in adult patients with breast cancer, melanoma, or localised squamous cell carcinoma of the oral cavity.

LYMPHOSEEK^® has been specifically designed to target, bind to and be retained in sentinel lymph nodes, the first lymph node (or group of nodes) to which cancer cells are most likely to spread from a primary tumour.^[1],[2],[3] LYMPHOSEEK^® has a false negative rate of 2.6% in T1-T4cN0 oral squamous cell carcinoma (OSCC).^[1] It detected sentinel lymph nodes in 98% of patients with Tis, Tx or T1-T4cN0 breast cancer and T1-T4cN0 melanoma.^[1],[4]

LYMPHOSEEK^® offers particular value in identifying lymphatic drainage from tumours in the floor of the mouth (underneath the tongue) which can prove especially difficult.^[6] Currently up to 70-80% of patients with early oral cancer receive elective neck dissection surgery, a major procedure which could be avoided by using sentinel lymph node biopsy (SLNB) for staging.^{[5],[6],[7],[8],[9],[10]} In major European markets*, 76,917 new cases of head and neck cancer were diagnosed in 2014.^[11]

"The mouth and neck areas are packed with vital structures affecting sight, hearing, taste and smell and essential functions such as breathing, swallowing and speech, all of which may be damaged during head and neck surgery," said Professor Mark McGurk, Consultant Surgeon at the Head & Neck Oncology Unit, University College Hospital London. "Adopting SLNB to stage their disease means that the majority of early stage oral cancer patients can avoid a neck dissection and, for them, unnecessary procedure."

"Using LYMPHOSEEK^® in sentinel lymph node biopsy has the potential to impact positively on patients, surgeons and use of hospital resources," commented Professor John Buscombe, Director of Nuclear Medicine, Addenbrooke's Hospital, Cambridge. "Early experience suggests LYMPHOSEEK^® can support a managed and scheduled transition of patients from imaging to surgery, lessening the amount of time both patients and surgical teams wait around as they can be confident that LYMPHOSEEK^® is retained in the lymph nodes to inform 'next day' surgery."

"Peter Martin, Chief Operating Officer, Norgine commented: "As a European multi-specialist pharma company, Norgine aims for all eligible patients to have their cancers accurately staged using sentinel lymph node biopsy with LYMPHOSEEK^®. This will result in a reduction in unnecessary surgical interventions that can optimise use of healthcare resources and improve patients' quality of life."

Norgine in-licensed LYMPHOSEEK^® from Navidea Biopharmaceuticals Inc for the commercialisation and distribution in Europe and certain other key markets. 

*Countries included were France, Germany, Italy, Spain and the United Kingdom.
