Lymphoseek as Lymphoid Tissue Targeting Agent in Patients With Cancer of the Endometrium

October 10, 2018 updated by: Michael McHale, University of California, San Diego

A Phase I, Prospective, Open-Label, Comparison Study of Lymphoseek® and Vital Blue Dye as Lymphoid Tissue Targeting Agents in Patients With Known Cancer of the the Endometrium Who Are Undergoing Lymph Node Dissection

Part of standard treatment for endometrial cancer is to remove one or more groups of lymph nodes (lymph node dissection). Lymph nodes are small, bean-shaped organs located within the body throughout the lymphatic system (the tissues and organs involved in immunity, which aids in the fight against infection and cancer).

The purpose of this study is to compare the safety and ability of Lymphoseek and a Vital Blue Dye (tracing agent) to find lymph nodes that may carry cancer from the tumor through the lymphatic system. Lymphoseek will be injected into the tumor on the day before surgery to remove lymph nodes. Vital Blue Dye will be administered during surgery to trace the cancer as well. The surgeon will remove the lymph nodes as part of routine surgery and will keep track of which lymph nodes are identified by Lymphoseek and Vital Blue Dye. These nodes will be sent to another doctor to view them under a microscope and see if the nodes contain cancer cells.

The hypothesis is that Lymphoseek can be used safely and will be at least as effective as blue dye in identifying the lymph nodes that may have cancer cells.

Detailed Description

This is an open-label, single center, intra-patient safety and comparison study of Lymphoseek (Technetium Tc 99m Tilmanocept) and vital blue dye for the detection of lymph nodes in patients with endometrial cancer that are undergoing a lymph node dissection as part of their standard medical care.

The day before surgery, patients will have their tumor injected with 50 µg Lymphoseek radiolabeled with 75 megabecquerel (MBq) Tc 99m. Vital signs will be monitored for thirty minutes and then patients will undergo a whole body scan and single photon emission computed tomography/ x-ray computed tomography (SPECT/CT) one to two hours after Lymphoseek injection.

Fourteen to twenty hours after injection of Lymphoseek, patients will have a physical exam and clinical laboratory tests assessed prior to undergoing surgery. Sentinel lymph node identification begins with injection of Vital Blue Dye. Surgical access will be made to the lymphatic basins where nodes are expected to be. Sentinel lymph nodes will be identified by a hand-held gamma counter and/or blue appearance. The threshold criterion for positive "hot" nodes based on radioactivity is a count greater than the quantity of 3 square roots of the mean background count (i.e., standard deviation) added to the mean background count (referred to as the "3σ rule"). Once a lymph node has been identified, in vivo counts should be taken prior to excision. In vivo counts will consist of a set of three 1-second counts over the lymph node. A positive finding (i.e., localization) is a designated "hot" node (described above). Any lymph node count not meeting this threshold criterion will be considered a negative (non-localized) finding. To confirm the in vivo procedure, a set of three 1-second counts will be recorded for the excised lymph nodes. The count of the ex vivo lymph nodes will be compared to the room background counts, and the threshold criterion used to determine a positive finding for the in vivo nodes will be applied to the ex vivo specimens.

A thorough evaluation of the remaining lymphatic basin will be complete when all selected node counts are negative by use of the threshold criterion. The surgeon will continue with visualization and palpation according to local practice to ensure that no grossly positive lymph nodes remain at the site of resection. After identifying the sentinel lymph nodes, standard lymph node dissection will be performed. All removed lymph nodes are sent to pathology for further evaluation. All removed lymph nodes will be sent to pathology and will be confirmed for radioactive status (due to Lymphoseek) and blue appearance (due to vital blue dye. The pathological evaluation of lymph node(s) will include serial sectioning with H&E staining as well as immuno-histochemistry (IHC) stain according to institutional practice.

Patients will return for a routine post-operative follow-up visit 7-14 days after surgery for assessment of adverse events.

The primary objective is safety of Lymphoseek as measured by the incidence of adverse events, changes in laboratory values, vital signs and physical exam findings, and the radiation absorbed dose. Secondary evaluations include (1) the number of lymph nodes detected as "hot" by preoperative imaging (whole body scan and SPECT/CT) and intraoperative gamma detection, and (2) the rate of concordance between Lymphoseek and Vital Blue Dye in the in vivo detection of excised lymph nodes.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
