Sentinel Lymph Node Localisation With an Ultra-low Dose of Magtrace in Breast Cancer Patients (MagSnow2)

January 25, 2024 updated by: Roger Olofsson Bagge, Vastra Gotaland Region

Sentinel Lymph Node Localisation With an Ultra-low Dose of Superparamagnetic Iron Oxide Nanoparticles in Patients With Breast Cancer

The overall aim is to demonstrate that the use of superparamagnetic iron oxide nanoparticles (SPIO) as a tracer in an ultra-low dose (0.1 ml) is non-inferior for sentinel lymph node (SLN) detection in patients with breast cancer compared to the dual technique using Tc99m +/- blue dye, and to evaluate MRI breast artefacts and skin staining over time.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The overall aim is to demonstrate that the use of superparamagnetic iron oxide nanoparticles (SPIO) as a tracer in an ultra-low dose (0.1 ml) is non-inferior for sentinel lymph node (SLN) detection in patients with breast cancer compared to the dual technique using Tc99m +/- blue dye, and to evaluate MRI breast artefacts and skin staining over time.

This is a prospective cohort study where all research persons have SLN biopsy using both SPIO and the dual technique. Then the investigators will compare SLN detection rates between Magtrace 0.1 ml and the dual routine technique with radioactive tracer (Technetium99m, Tc99) +/- blue dye.

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

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.

Ages Eligible for Study

  • Adult
  • Older Adult

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Other: Sentinel node detection with 0.1mL SPIO and Technetium99
An intradermal injection of SPIO (MagTrace®), according to the pre-specified dose of 0.1mL, will be performed 7 days, up to the day of surgery. The injection should be in the skin over the tumour, or at the border of the areola. All patients will also receive technetium per routine.
Drug: Superparamagnetic Iron Oxide
Superparamagnetic iron oxide (SPIO) consists of an iron oxide nanoparticle core and a hydrophilic coating to make it biocompatible and colloidal stable in a suspension. In this study injected intradermally in an ultra-low dose
Other Names:
  • Magtrace
Device: Technetium99
Technetium99 +/- blue dye is injected per routine as a comparator and as back up.

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
SLN detection rate for Magtrace 0.1 ml and for dual technique (Tc99 +/- blue dye) measured as per cent of patients where a SLN is identified using either the magnetic or the dual technique.
Time Frame: During the procedure
percentage
During the procedure

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.
