Study Summary

This trial will use a new fluorescence imaging agent, LS301, to help surgeons more accurately remove all cancer cells during surgery for breast cancer.

Who is the study for?
This trial is for adults over 18 with newly diagnosed Stage I-II breast cancer, planning to have breast-conserving therapy and SLN biopsy. They must understand and sign consent. Excluded are breastfeeding or pregnant women, those unfit for surgery, on other trials, with lung disease or allergies to study agents like ICG.Check my eligibility
What is being tested?
The trial tests Cancer Vision Goggles (CVG) combined with LS301 dye during surgery to see if they can better identify cancer cells and reduce positive margins in breast cancer surgeries. Phase 1 checks safety/dose of LS301; Phase 2 assesses its ability to detect cancer at surgical margins.See study design
What are the potential side effects?
Potential side effects may include allergic reactions similar to those seen with iodine-based dyes or seafood allergies due to the use of LS301 dye in the procedure. However, since LS301 isn't radioactive nor contains iodinated ions, fewer adverse reactions are expected.

Treatment Details

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
Ability of LS301 to predict presence of positive margins around partial mastectomy (Phase II)
Optimal imaging dose of LS301 (Phase I)
Safety of LS301 in breast as measured by related adverse events (Phase I)
Secondary outcome measures
Toxicity of LS301 in breast as measured by related adverse events (Phase II)

Trial Design

5Treatment groups
Experimental Treatment
Group I: Phase II: LS301Experimental Treatment3 Interventions
Patient will undergo surgery 4-24 hours after administration of LS301 (dose to be determined in Phase I portion) Excised tissue will be examined for the presence of LS301 fluorescence using the Cancer Vision Goggles (CVG) to determine if LS301 accumulated in the breast cancer. The investigators will quantify fluorescence intensity in the cancer to establish the feasibility of observing LS301 fluorescence with the imaging system. FDA-approved fluorescence imaging systems may be used to benchmark CVG data.
Group II: Phase I Dose Level 3: LS301Experimental Treatment3 Interventions
Patient will undergo surgery 4-24 hours after administration of LS301 (0.1 mg/kg) Excised tissue will be examined for the presence of LS301 fluorescence using the Cancer Vision Goggles (CVG) to determine if LS301 accumulated in the breast cancer. The investigators will quantify fluorescence intensity in the cancer to establish the feasibility of observing LS301 fluorescence with the imaging system. FDA-approved fluorescence imaging systems may be used to benchmark CVG data.
Group III: Phase I Dose Level 2: LS301Experimental Treatment3 Interventions
Patient will undergo surgery 4-24 hours after administration of LS301 (0.075 mg/kg) Excised tissue will be examined for the presence of LS301 fluorescence using the Cancer Vision Goggles (CVG) to determine if LS301 accumulated in the breast cancer. The investigators will quantify fluorescence intensity in the cancer to establish the feasibility of observing LS301 fluorescence with the imaging system. FDA-approved fluorescence imaging systems may be used to benchmark CVG data.
Group IV: Phase I Dose Level 1: LS301Experimental Treatment3 Interventions
Patient will undergo surgery 4-24 hours after administration of LS301 (0.05 mg/kg) Excised tissue will be examined for the presence of LS301 fluorescence using the Cancer Vision Goggles (CVG) to determine if LS301 accumulated in the breast cancer. The investigators will quantify fluorescence intensity in the cancer to establish the feasibility of observing LS301 fluorescence with the imaging system. FDA-approved fluorescence imaging systems may be used to benchmark CVG data.
Group V: Phase I Dose Expansion: LS301Experimental Treatment3 Interventions
Patient will undergo surgery 4-24 hours after administration of LS301 (dose to be determined in Phase I dose escalation portion) 9 patients will be enrolled (6 invasive ductal carcinoma and 3 DCIS) Excised tissue will be examined for the presence of LS301 fluorescence using the Cancer Vision Goggles (CVG) to determine if LS301 accumulated in the breast cancer. The investigators will quantify fluorescence intensity in the cancer to establish the feasibility of observing LS301 fluorescence with the imaging system. FDA-approved fluorescence imaging systems may be used to benchmark CVG data.
