infiltrating ductal breast cancer with size > 1.5 cm by palpation, excluding breast
cancer where neoadjuvant chemotherapy is indicated by current guidelines (i.e.
inflammatory subtype, etc.)
- Tumor that is palpable and injectable
- Hemoglobin >= 9 g/dL

bilirubin =< 3 x ULN
- Albumin >= 2.5 g/dl
- Prothrombin time (PT) / International normalized ratio (INR) and partial
thromboplastin time (PTT) =< 1.5 x institutional upper limit of normal unless the
patient is on anticoagulant therapy within 28 days prior to enrollment (if the patient
is receiving anticoagulant therapy, PT, and a PTT must be within therapeutic range of
intended use of anticoagulants)
- Patients must be willing to submit blood and tissue specimens for translational
medicine studies
- Patients must be offered the opportunity to participate in specimen banking for future
research
- Women of childbearing potential (WOCBP) must have a negative serum or urine pregnancy

- Women of childbearing potential (WOCBP) must be willing to use either two adequate
barrier methods or a barrier method plus a hormonal method of contraception to prevent
pregnancy, or to abstain from heterosexual activity (complete abstinence) throughout

keloid formation, etc.)

condom to avoid potential viral transmission during sexual contact while on treatment
and within 30 days after treatment with talimogene laherparepvec
- Inability to give informed consent

carcinoma, melanoma in situ, superficial bladder cancer or carcinoma in situ of the
cervix; for other malignancies, must be documented to be free of cancer for >= 2
years. All other cases can be considered on a case by case basis at the discretion of
the principal investigator
- Any condition that might interfere with the subject?s participation in the study,
safety, or in the evaluation of the study results
- Concurrent enrollment in another clinical study, unless it is an observational
(non-interventional) clinical study or the follow-up period of an interventional study
- Prior exposure to any anti-PD-1 or anti-PD-L1 antibody, or any anti-CTLA 4 antibodies
- Patients must not have received prior treatment with talimogene laherparepvec or other
oncolytic virus agents
- Patients must not have received any live vaccine within 30 days prior to registration.
Seasonal flu vaccines that do not contain live virus are permitted
- Patients must not have an active infection requiring systemic therapy nor a viral
infection requiring intermittent treatment with an antiherpetic drug, other than
intermittent topical use
- Patients must not have active herpetic skin lesions or prior complications of herpetic
infection (e.g., herpetic keratitis or encephalitis) which requires intermittent or
chronic treatment with an anti-herpetic drug other than intermittent topical use
- Any concurrent chemotherapy, immunotherapy, biologic or hormonal therapy for cancer
treatment. Concurrent use of hormones for non-cancer-related conditions (e.g., insulin
for diabetes and hormone replacement therapy) is acceptable
- Patient must not have evidence of any clinically significant immunosuppression such as
the following: primary immunodeficiency state such as severe combined immunodeficiency
disease; concurrent opportunistic infection; receiving systemic immunosuppressive
therapy within 28 days before enrollment with the exceptions of intranasal, topical,
and inhaled corticosteroids or oral corticosteroids at physiologic doses not to exceed
10 mg/day of prednisone or equivalent
- Patients must not have known history human immunodeficiency virus (HIV)

condition only requiring hormone replacement, psoriasis not requiring systemic
treatment, or conditions not expected to recur in the absence of an external
trigger are permitted to enroll
