Navidea Biopharmaceuticals, Inc. (NYSE MKT: NAVB) today
announced that data and results from its Lymphoseek® (technetium Tc
99m tilmanocept) injection studies in breast cancer, melanoma or
head and neck cancer were recently presented at the European
Association of Nuclear Medicine Congress in Gothenberg, Sweden and
will be presented this week at the European Society of Surgical
Oncology-British Association of Surgical Oncology Congress from
October 29-31, 2014 in Liverpool, UK.
“Following our recent positive opinion by the Committee for
Medicinal Products for Human Use (CHMP) and the anticipated
approval by the European Commission later this year, we are pleased
to share these exciting Lymphoseek results with the European
medical community,” said Rick Gonzalez, Navidea Chief Executive
Officer. “We believe the targeted technology of Lymphoseek is an
advance in the reliable and accurate location of sentinel lymph
nodes aiding more effective cancer staging and better informing
post-surgical treatment. Taken together with this month’s U.S. FDA
approval for lymphatic mapping in all solid tumors, momentum
continues to build toward our primary goal of making Lymphoseek the
global standard of care in lymphatic mapping.”
Details of the presentations by Navidea and its collaborators
are listed below.

The presentations showed 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%).
About LymphoseekLymphoseek® (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 been recommended by CHMP for European
approval for the following indication:
- 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
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.
U.S. Lymphoseek Indication and Important Safety
InformationLymphoseek is a radioactive diagnostic agent
indicated with or without scintigraphic imaging for:
- Lymphatic mapping using a handheld
gamma counter to locate lymph nodes draining a primary tumor site
in patients with solid tumors for which this procedure is a
component of intraoperative management.
- Guiding sentinel lymph node biopsy
using a handheld gamma counter in patients with clinically node
negative squamous cell carcinoma of the oral cavity, breast cancer
or melanoma.
Important Safety InformationIn 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%).
