Trial ID Title Status Sponsor Phase Start Date Summary
NCT00671918 ↗ Trial of Lymphoseek in Intraoperative Localization of Lymph Nodes in Breast Cancer and Melanoma Completed Navidea Biopharmaceuticals Phase 3 2008-04-01 Data from this pivotal clinical trial will be used to support a marketing application (i.e., NDA) for Navidea's Lymphoseek for use in intraoperative localization of lymph tissue (nodes) in the lymphatic pathway draining the primary site of a tumor.
NCT00911326 ↗ Evaluation of Sentinel Lymph Nodes in Head and Neck Squamous Cell Carcinoma Terminated Navidea Biopharmaceuticals Phase 3 2009-05-01 The purpose of this study is to determine the false negative rate (FNR) associated with Lymphoseek-identified sentinel lymph nodes (SLNs) relative to the pathological status of non-sentinel lymph nodes in elective neck dissection (END) in head & neck squamous cell carcinoma (HNSCC). NEO3-06 (this study) is a Phase 3 clinical trial designed to supplement NEO3-05, a completed Phase 3 clinical trial conducted in patients with breast cancer or melanoma. NEO3-05 was designed to establish Lymphoseek as an effective radio-diagnostic agent to be used in the intraoperative localization of lymph tissue (nodes) in the lymphatic pathway draining the primary site of a tumor.
NCT01106040 ↗ Breast and Melanoma Trial With Lymphoseek to Identify Lymph Nodes Completed Navidea Biopharmaceuticals Phase 3 2010-06-01 Data from this pivotal clinical trial will be used to support a marketing application (i.e., NDA) of Navidea's Lymphoseek for use in anatomical delineation of lymphoid tissue (nodes) in the lymphatic pathway draining the primary site of a tumor. Multicenter, open-label, within-patient comparative study of Lymphoseek and vital blue dye in the detection of excised lymph nodes in patients with known melanoma and breast cancer. All patients will receive a single dose of 50 µg Lymphoseek radiolabeled with 0.5 or 2.0 mCi Tc 99m and vital blue dye.
NCT01902953 ↗ Lymphoseek® as Lymphoid Tissue Targeting Agents in Colon Cancer(CNC) Completed Maimonides Medical Center Phase 2 2013-03-01 45 patients undergoing a colon (large bowel/intestine)removal operation for the diagnosis of colon cancer will be included in this study. During colon operation the affected portion of the colon is removed. In addition, lymph nodes are included in the specimen and evaluated by a pathologist. Analysis of the lymph nodes in the specimen are important because this is an important aspect of determining the stage of the cancer. Once the standard technique is used for the colon removal operation and the specimen is removed it will be injected with two drugs to help identify the lymph nodes. One is a blue dye and the other a radiotracer. The colon and ALL of the lymph nodes will then be sent for the standard pathologic evaluation. The patient themselves will never be injected with these drugs being used for research. Following the standard lymph node evaluation, an additional pathologist at an outside research facility will further examine the lymph nodes in the specimen using more in depth techniques which are above and beyond the standard of care. The results of all the pathologic tests will be conveyed to the surgeon of record to help in their decision making regarding further treatment. The study hypothesis is that radiotracer will be at least as effective as blue dye in identifying the lymph nodes most likely to harbor cancer cells (sentinel nodes). Once identified, these sentinel nodes can then undergo a more in depth review leading to improved staging of colorectal cancer and more accurate treatment.
NCT02065232 ↗ Sentinel Lymph Node Mapping Post-Injection Site Pain Completed Navidea Biopharmaceuticals 2014-03-01 This is a pain survey study that will compare the level of discomfort experienced by breast cancer patients after injection of either technetium-labeled sulfur colloid or technetium-labeled tilmanocept, both FDA-approved agents used for sentinel lymph node biopsy (SLNB). Breast cancer patients who are already scheduled for SLNB as part of their original surgical plan will be asked to participate in this study and be randomized to receive either technetium-labeled sulfur colloid or technetium-labeled tilmanocept. After injection, patients will complete pain questionnaires to measure the amount of discomfort they are feeling during and after they receive the injection. There will be no change to the patient's treatment plan other than the addition of pain questionnaires. The investigators' hypothesis is that patients will feel less discomfort after injection of tilmanocept versus sulfur colloid.

LYMPHOSEEK®: A Comprehensive Update on Clinical Trials, Market Analysis, and Projections

Introduction to LYMPHOSEEK®

LYMPHOSEEK® (technetium Tc 99m tilmanocept) is a groundbreaking radioactive diagnostic agent specifically designed for targeted lymphatic mapping and guiding sentinel lymph node biopsies (SLNB). Developed by Navidea Biopharmaceuticals and now part of Cardinal Health’s portfolio, LYMPHOSEEK® has revolutionized the field of oncology by providing accurate and precise lymph node identification in patients with solid tumors.

Clinical Efficacy and Trials

Solid Tumors: Breast Cancer and Melanoma

The clinical efficacy of LYMPHOSEEK® was demonstrated in two pivotal Phase 3 open-label, multicenter, single-arm, within-subject active-comparator trials involving patients with breast cancer or melanoma. These trials compared LYMPHOSEEK® with vital blue dye (VBD), a long-standing agent for lymphatic mapping. The results showed high concordance between LYMPHOSEEK® and VBD, with LYMPHOSEEK® identifying lymph nodes in 94-100% of patients, significantly outperforming VBD in several metrics[1][2][4].

Head and Neck Squamous Cell Carcinoma (SCC)

In a Phase 3 trial focusing on head and neck SCC, LYMPHOSEEK® demonstrated a high sensitivity for detecting cancer in lymph nodes, with a false negative rate of only 2.6%. The study involved 83 patients and showed that LYMPHOSEEK® identified at least one sentinel lymph node in 97.6% of patients, including those with challenging floor of mouth tumors[1].

Pediatric Indication

A recent clinical study has expanded the use of LYMPHOSEEK® to pediatric patients aged one month and older with solid tumors such as melanoma, rhabdomyosarcoma, and non-rhabdomyosarcoma soft tissue sarcoma. The study confirmed the safety and efficacy of LYMPHOSEEK® in this population, with minimal adverse reactions reported[3].

Mechanism of Action

LYMPHOSEEK® works by binding to a specific receptor found on the surface of dendritic cells and macrophages, which are highly concentrated in lymph nodes. This receptor-targeted property allows LYMPHOSEEK® to attach to and remain within lymph nodes, enabling precise identification during surgical procedures[2][4].
