      - Leukocytes > 3,000/microlitre (mcL).

      - Platelets > 75,000/mcL

      - Aspartate aminotransferase (AST (SGOT))/alanine transaminase (ALT (SGPT)) < 2.5 X
      institutional upper limit of normal

      - Creatinine ≤ 1.5 mg/dL or creatinine clearance > 60 mL/min/1.73 m2 for subjects
      with creatinine levels above institutional normal.

   - Subjects with Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.

Exclusion Criteria:

   - Subjects who have been diagnosed with bilateral breast cancer and are undergoing
   bilateral resection procedure

   - Subjects who are pregnant. Breastfeeding should be discontinued if the mothers is
   treated with Pegulicianine (LUM015)

   - Subjects who are sexually active and not willing/able to use 2 medically acceptable
   forms of contraception (hormonal or barrier method of birth control, abstinence) upon
   entering the study and for 60 days after injection of LUM015.

   - Subjects who have taken an investigational drug within 30 days of enrollment.

   - Subjects who will have administration of methylene blue or any dye for sentinel lymph
   node mapping on the day of the surgery prior to imaging the lumpectomy cavity with the
   LUM Imaging Device.

   - Subjects who have not recovered from adverse events due to other pharmaceutical or
   diagnostic agents.

   - Subjects with uncontrolled hypertension defined as persistent systolic blood pressure
   > 180 mm Hg, or diastolic blood pressure > 110 mm Hg; those subjects with known
   hypertension (HTN) should be stable with controlled HTN while under pharmaceutical
   therapy.

   - History of allergic reaction to any oral or intravenous contrast agents.

   - Uncontrolled intercurrent illness including, but not limited to ongoing or active
   infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac
   arrhythmia, chronic obstructive pulmonary disease (COPD) or asthma requiring
   hospitalization within the past 12 months, or psychiatric illness/social situations
   that would limit compliance with study requirements.

   - HIV-positive individuals on combination antiretroviral therapy are ineligible.

   - Any subject for whom the investigator feels participation is not in the best interest
   of the subject.

   - Subjects undergoing a second lumpectomy procedure because of positive margins in a
   previous surgery prior to entering this study

   - Subjects with post-biopsy hematomas greater or equal to 2 cm that are visible on
   physical exam or detected during pre-operative observations.

   - Subjects with prior ipsilateral breast cancer surgeries, mastectomies, breast
   reconstructions or implants.s with prior ipsilateral breast cancer surgeries,
   mastectomies, breast reconstructions or implants

   - Subjects with prior ipsilateral reduction mammoplasties (breast reductions) performed
   less than 2 years prior to enrollment to this study.

   - Subjects previously treated with systemic therapies to treat the cancer to be removed
   during this clinical investigation, such as neo-adjuvant chemotherapy or hormonal
   therapy.

   - Subjects undergoing breast conserving surgery whose resected specimen (main lump,
   shaves, or any other resected tissue) will be evaluated with frozen section after the
   LUM-guided removal of shaves.
