This is a pilot study to investigate the change in the immune microenvironment of high risk ductal carcinoma in situ (DCIS) after short term exposure to pembrolizumab.
Testing the Ability of Pembrolizumab and mRNA 2752 to Alter the Tumor Immune MicroEnvionment (TIME) of High Risk DCIS
This study will include 3 dose cohorts using a 3+3 cohort dose escalation design followed by a 4th cohort (the dose expansion phase) at the maximum tolerated dose. Unless a dose limiting toxicity (DLT), defined any grade 3 or 4 toxicity, is observed requiring expansion of a cohort or a subject withdraws, 3 subjects will be enrolled into each cohort in the dose escalation phase. Subjects, upon diagnosis with high risk DCIS, will be offered 2 doses of pembrolizumab injected intralesionally (IL) 3 weeks apart (+/- 1 week) with surgery 3 weeks (+/- 2 weeks) after the 2nd dose. The subject will then undergo the surgical treatment as determined by the surgeon and the subject (partial mastectomy or mastectomy). The primary objective of this phase of the study will be safety and feasibility of intralesional injection of pembrolizumab.
The maximum tolerated dose will be used in the expansion phase. The expansion cohort will have a target enrollment of 30 subjects enrolled to either the control group or the treatment group. The treatment group will consist of 20 subjects who agree to receive the treatment. The control group will consist of 10 eligible subjects who decline treatment and agree to tissue collection and to the use of tissue for research purposes. The control group will proceed to surgery alone within a 4 month timeframe following the diagnosis of high risk DCIS. The treatment group will receive 4 doses of intralesional pembrolizumab monotherapy 3 weeks apart (+/- 1 week) prior to surgery (first 5 patients enrolled) but will now receive 2 doses of intralesional pembrolizumab and intralesional mRNA 2752 3 weeks apart (+/- 1 week) prior to surgery. All subjects in the expansion cohort will also undergo a baseline MRI at diagnosis and undergo a 2nd MRI prior to surgery. Baseline and pre-surgical MRI images will be evaluated for changes in tumor volume.
Note: The last patient finished the escalation phase on 08/14/2018, and the study is currently in the expansion phase.

- Patients with a history of tamoxifen and/or aromatase inhibitor use for treatment or prevention are eligible but should discontinue these medications at least 2 weeks prior to starting this trial
- Be willing and able to provide written informed consent/assent for the trial.
- Be >=18 years of age on day of signing informed consent.
- Have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1
- Demonstrate adequate organ function:
- All screening labs should be performed within 10 days of treatment initiation.
- Hematological Absolute Neutrophil Count (ANC) >=1,500/microliter (mcL) Platelets >=100,000/mcL Hemoglobin >=9 g/dL or >=5.6 mmol/L without transfusion or erythropoietin (EPO) dependency (within 7 days of assessment)
- Renal Serum creatinine <=1.5 X upper limit of normal (ULN) OR Measured or calculated creatinine clearance (GFR can also be used in place of creatinine or CrCl) >=60 mL/min for subject with creatinine levels > 1.5 X institutional ULN
- Hepatic Serum total bilirubin <=1.5 x ULN OR Direct bilirubin <= ULN for subjects with total bilirubin levels > 1.5 ULN aspartate aminotransferase (AST) / serum glutamic-oxaloacetic transaminase (SGOT) and alanine aminotransferase (ALT) / serum glutamic-pyruvic transaminase (SGPT) <= 2.5 X ULN Albumin >=2.5mg/dL
- Coagulation International Normalized Ratio (INR) or Prothrombin Time (PT) <=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 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
- Female subjects of childbearing potential should have a negative urine or serum pregnancy within 72 hours prior to receiving the first dose of study medication. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.
- Female subjects of childbearing potential should be willing to use 2 methods of birth control or be surgically sterile, or abstain from heterosexual activity for the course of the study through 120 days after the last dose of study medication (Reference Section 5.7.2). Subjects of childbearing potential are those who have not been surgically sterilized or have not been free from menses for > 1 year.
- 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.

- Has a known history of active Bacillus Tuberculosis (TB)
- Hypersensitivity to pembrolizumab or any of its excipients.

- 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.

10. Has a history or current evidence of any condition, therapy, or laboratory abnormality

11. Has known psychiatric or substance abuse disorders that would interfere with
cooperation with the requirements of the trial.

reactive) or known active Hepatitis C virus (HCV) (defined as HCV RNA [qualitative] is detected) infection. Note: no testing for Hepatitis B and Hepatitis C is required unless mandated by local health authority.
15. 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-Guérin (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.
