About this study

To learn if Pegulicianine Fluorescence-Guided Surgery (pFGS), which is part of the Lumicell Direct Visualization System, and Digital Breast Tomosynthesis (DBT) can improve the identification of tumor margins during a partial mastectomy and decrease the need for a second surgery.

Read the detailed description

Primary Objectives:

-To determine if surgeon interpretation of pFGS and DBT has a higher specificity compared to SEP, resulting in fewer excisions of additional tissue unnecessarily

Secondary Objectives:

  • To determine if surgeon evaluation of segmental mastectomy margins using pFGS and DBT is associated with better patient- and physician-reported cosmesis
  • To determine if surgeon interpretation of pFGS and DBT results in a lower rate of positive margins after BCS compared to SEP
  • To determine if surgeon interpretation of pFGS and DBT has a shorter operative time compared to SEP.
  • To determine if surgeon interpretation of pFGS and DBT results in less delays in receipt of adjuvant treatment and the reduction of targeted volume of radiation therapy or omission of radiation altogether

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

safety and adverse events (AEs). Incidence of Adverse Events, Graded According to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) Version (v) 6.0 (time frame: Through study completion; an average of 1 year.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Oct 2026.
