July 14, 2020 updated by: Kettering Health Network

A Randomized, Double-Blinded Trial Comparing Lymphoseek and 99mTc-Sulfur Colloid With Regard to Pre-op Imaging and Imaging Drug Kinetics and Intra-op Lymphatic Mapping and Sentinel Lymph Node Biopsy Findings in Patients With Breast Cancer

To compare the kinetics and efficacy of two functionally different diagnostic agents, Lymphoseek (CD206 receptor targeted) and 99mTc-Sulfur Colloid (SC) (Sulfur Colloid non-specific mapping agent) in intraoperative lymphatic mapping (ILM) and Sentinel Lymph Node Biopsy (SLNB).

Active Comparator: Lymphoseek
Lymphoseek (technetium Tc 99m tilmanocept) Injection is indicated for lymphatic mapping with a hand-held gamma counter to assist in the localization of lymph nodes draining a primary tumor site in patients with breast cancer or melanoma and guiding sentinel lymph node biopsy using a hand-held gamma counter in patients with clinically node negative squamous cell carcinoma of the oral cavity.
Drug: Lymphoseek
Subjects will receive a single intradermal injection of Lymphoseek followed by SPECT imaging conducted in two phases: initial sequential planar imaging at 30 to 60 second intervals for the first 60 minutes and repeated at 90 minutes and 120 minutes, as indicated, for identification of the SLN followed by SPECT/CT for higher resolution imaging in transaxial, coronal, and sagittal planes. Subjects will then proceed to surgery for lymphatic mapping. Lymphoseek positivity will be based upon radioactivity counts derived from the application of the handheld gamma probe ex vivo. Tumor resection or mastectomy will be performed according to standard procedures.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Injection Site Clearance for Lymphoseek and 99mTc-Sulfur Colloid (SC).
Time Frame: 2 hours
The rate of injection site clearance is the time from radiotracer injection to peak SLN radioactive level. Injection clearance rates will be determined by planar SPECT imaging and by SPECT/CT. Subjects will undergo standard sequential planar imaging at 30 to 60 seconds intervals until the sentinel lymph node is seen. Once a sentinel node is located, a SPECT/CT will be performed for higher resolution imaging in transaxial, coronal, and sagittal planes.
2 hours
Sentinel Lymph Node Uptake Rate
Time Frame: 2 hours
SLN uptake rates will be determined by planar SPECT (single-photon emission computerized tomography) imaging and by SPECT/CT (CT-computed tomography). Gamma counts will be obtained at the injection site by standard sequential planar imaging at 30 to 60 seconds intervals until the sentinel lymph node is seen. Once a sentinel node is located, a SPECT/CT will be performed for higher resolution imaging in transaxial, coronal, and sagittal planes. Figures showing the percent of peak activity in the node versus time will be constructed for each radiopharmaceutical. The average uptake rate for each radiopharmaceutical will be computed and the following test will be conducted using a two-sample t-test at a two-sided α=0.05 (one-sided α=0.025) level of significance: H0 (null hypothesis): µLS ≤ µSC vs. HA (alternative hypothesis): µLS > µSC, (µLS is the average SLN uptake rate of Lymphoseek) (µSC is the average SLN uptake rate of 99mTc Sulfur Colloid).
2 hours

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Intraoperatively Detected Sentinel Lymph Nodes (SLNs) Identified
Time Frame: 24 hours
To compare the number of intraoperatively detected SLNs identified by Lymphoseek and 99mTc-SC on an agent cohort basis
24 hours
Ratio of Intraoperative Gamma Counts
Time Frame: 24 hours
To compare differences in the ratio of intraoperative counts for Lymphoseek vs 99mTc-SC for the hottest harvested axillary Sentinel Lymph Node (SLN) relative to the primary intradermal injection site.
24 hours
Patient Pain Tolerance
Time Frame: 24 hours
To compare patient pain tolerance (i.e., patient's perceived level of discomfort) at the injection site for Lymphoseek vs 99mTc-SC using Wong-Baker pain rating scale of 0-10, where the higher the score, the higher the pain level.
24 hours
Pathologic Assessment of the Excised Lymph Node(s)
Time Frame: 24 hours
To compare pathologic assessment of the excised lymph node(s) to confirm the presence/absence of tumor metastases for Lymphoseek vs 99mTc-SC.
