The purpose of this pivotal study is to provide prospective evidence that the SentiMag®/SiennaXP® is safe and non-inferior to the current standard of care for lymph node localization in patients with breast cancer as part of a sentinel lymph node biopsy (SLNB) procedure and to summarize measures of product safety and performance.
This is a pivotal, prospective, open label, multicenter, paired comparison of the SentiMag® and SiennaXP® magnetic sentinel node localization system with the standard of care (radioisotope with blue dye) for lymph node localization in the detection of lymph nodes in patients with breast cancer undergoing a sentinel lymph node biopsy. The trial is designed to provide powered evidence that the lymph node detection rate of the SentiMag® and SiennaXP® system is non-inferior to the standard of care in patients with breast cancer.

Device SiennaXP

Sub-cutaneous injection of SiennaXP magnetic marker, followed by lymph node localization using the SentiMag handheld magnetic probe

Drug Technetium Tc99m Sulfur Colloid

Injection of a single dose of radioisotope (Technetium Tc99m Sulfur Colloid)

  • Other names: Radioisotope

Drug Isosulfan blue dye

Injection of a single dose of isosulfan blue dye

  • Other names: Blue dye

SiennaXP injection Experimental

Single injection of SiennaXP in addition to comparator single dose of radioisotope (Technetium Tc99m Sulfur Colloid) and single dose of isosulfan blue dye. Lymph node localization using the SentiMag handheld intraoperative localization system in addition to localization with standard of care handheld gamma probe.
