Pembrolizumab in Treating Patients with High Grade Ductal Breast Carcinoma In Situ
This pilot early phase I trial studies the best dose and side effects of pembrolizumab and to see how well it works in treating patients with high grade ductal breast carcinoma in situ. Monoclonal antibodies, such as pembrolizumab, may block tumor growth in different ways by targeting certain cells.

- Albumin >= 2.5 mg/dL (within 10 days of treatment initiation)
- International normalized ratio (INR) or prothrombin time (PT) =< 1.5 X ULN unless subject is receiving anticoagulant therapy as long as PT or partial thromboplastin time (PTT) is within therapeutic range of intended use of anticoagulants (within 10 days of treatment initiation)
- Activated partial thromboplastin time (aPTT) =< 1.5 X ULN unless subject is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants (within 10 days of treatment initiation)
- A female participant is eligible to participate if she is not pregnant, not breastfeeding, and at least one of the following conditions applies: * Not a woman of childbearing potential (WOCBP) OR * A WOCBP who agrees to follow the contraceptive guidance during the treatment period and for at least 90 days corresponding to time needed to eliminate any study treatment plus 30 days (a menstruation cycle) after the last dose of study treatment
- A male participant must agree to use a contraception during the treatment period and for at least 90 days corresponding to time needed to eliminate any study treatment plus an additional 120 days (a spermatogenesis cycle) after the last dose of study treatment and refrain from donating sperm during this period
- Is currently participating and receiving study therapy or has participated in a study of an investigational agent and received study therapy or used an investigational device within 4 weeks of the first dose of treatment
- Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to the first dose of trial treatment
- Is not interested in surgical treatment for her DCIS
- Has invasive breast cancer; this does not include microinvasion
- Has a known history of active TB (Bacillus tuberculosis)
- Hypersensitivity to pembrolizumab or any of its excipients
- Has a known additional malignancy that is progressing or requires active treatment; exceptions include basal cell carcinoma of the skin or squamous cell carcinoma of the skin that has undergone potentially curative therapy or in situ cervical cancer
- Has active autoimmune disease that has required systemic treatment in the past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs); replacement therapy (e.g. thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment
- Has a history of (non-infectious) pneumonitis that required steroids or has current pneumonitis
- Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject’s participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating investigator
- Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial
- Is pregnant or breastfeeding, or expecting to conceive or father children within the projected duration of the trial, starting with the pre-screening or screening visit through 120 days after the last dose of trial treatment
- Has a known history of human immunodeficiency virus (HIV) (HIV 1/2 antibodies)
- Has known active hepatitis B (e.g., hepatitis B surface antigen [HBsAg] reactive) or hepatitis C (e.g., hepatitis C virus [HCV] ribonucleic acid [RNA] [qualitative] is detected) infection; note: no testing for hepatitis B and hepatitis C is required unless mandated by local health authority
- Has received a live vaccine within 30 days prior to the first dose of study drug; examples of live vaccines include, but are not limited to, the following: measles, mumps, rubella, varicella/zoster (chicken pox), yellow fever, rabies, Bacillus Calmette–Guerin (BCG), and typhoid vaccine; seasonal influenza vaccines for injection are generally killed virus vaccines and are allowed; however, intranasal influenza vaccines (eg, FluMist) are live attenuated vaccines and are not allowed

Trial Objectives and Outline
I. To determine the maximum tolerated dose (MTD), and recommended dose for subsequent expansion cohort, of intralesionally administered pembrolizumab in patients with ductal carcinoma in situ (DCIS) of the breast. (Dose escalation phase)
II. To define the dose-limiting toxicities (DLTs), tolerability, and feasibility of intralesional administration of pembrolizumab in patients with DCIS. (Dose escalation phase)
III. To determine the response rate to intralesional pembrolizumab in patients with DCIS, as measured by an increase (baseline versus [vs.] post treatment) in intralesional CD8+ T cells, compared to untreated controls. (Dose expansion phase)
I. To determine whether intralesional pembrolizumab decreases tumor volume on magnetic resonance (MRI) imaging.
II. To determine the extent of cell death within the DCIS lesions (pre- vs. post-therapy) using a cleaved caspase 3 immunohistochemistry (IHC) assay.
III. To characterize changes in the immune landscape of DCIS following intralesional administration of pembrolizumab.
IV. To characterize changes in peripheral blood-based immune biomarkers.
OUTLINE: This is a dose-escalation study.
Patients receive pembrolizumab intralesionally on day 1 of a 3 week cycle for a total of 4 cycles.
After completion of study treatment, patients are followed up for 8 weeks.
