Outcome Measures

Primary Outcomes (3)

  • Maximum tolerated dose (MTD)

    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.

    18 months

  • Number of participants with Dose-limiting toxicities (DLTs)

    To define the dose-limiting toxicities (DLTs), tolerability, and feasibility of intralesional administration of pembrolizumab in patients with DCIS.

    18 months

  • Percentage of patients who demonstrate an increase (baseline vs. post intralesional injection) in intralesional CD8+ T cells

    To determine the response rate to intralesional pembrolizumab in patients with DCIS, as measured by an increase (baseline vs. post treatment) in intralesional CD8+ T cells, compared to untreated controls.

    post intralesional injection

Other Outcomes (2)

  • Changes in Mean Tumor volume

    18 months

  • Exploratory immunological responses to pembrolizumab before and after intralesional injection as measured using multiplex immunofluorescence on formalin-fixed paraffin-embedded (FFPE) tissue sections

    18 months

Study Arms (6)

CLOSED:Pembrolizumab intralesionally (IL) x 2 doses (Escalation Phase)

EXPERIMENTAL

Participants, 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 participant will then undergo the surgical treatment as determined by the surgeon and the participant (partial mastectomy or mastectomy).

Drug: Pembrolizumab

CLOSED:Pembrolizumab IL x 4 doses (Expansion Phase)

EXPERIMENTAL

Participants, upon diagnosis with high risk DCIS, will be offered 4 doses of pembrolizumab injected intralesionally (IL) 3 weeks apart (+/- 1 week) with surgery 3 weeks (+/- 2 weeks) after the 4th dose. The participant will then undergo the surgical treatment as determined by the surgeon and the participant (partial mastectomy or mastectomy).

Drug: Pembrolizumab

CLOSED:Pembrolizumab IL x 2 doses + mRNA 2752 IL x 2-4 doses (Expansion Phase)

EXPERIMENTAL

Participants, upon diagnosis with high risk DCIS, will be offered 2 doses of pembrolizumab and intralesional mRNA 2752 injected intralesionally (IL) 3 weeks apart (+/- 1 week) with surgery 3 weeks (+/- 2 weeks) after the 2nd dose. The participant will then undergo the surgical treatment as determined by the surgeon and the participant (partial mastectomy or mastectomy).

Drug: PembrolizumabBiological: Intralesional mRNA 2752

mRNA-2752 Monotherapy x 2-4 doses (Escalation Cohort)

EXPERIMENTAL

Participants will be offered up to 4 doses of mRNA-2752 injected intralesionally (IL) 3 weeks apart (+/- 1) week) with surgery or core biopsy 3 weeks (+/-1 week). The participants will proceed to biopsy, either image guided or excisional or partial mastectomy

Biological: Intralesional mRNA 2752

mRNA-2752 x 2-4 doses with or without immune checkpoint inhibitor (Expansion Cohort)

EXPERIMENTAL

Participants will be will be offered injections of mRNA-2752 given on up to 4 occasions, 3 weeks apart (+/- 1 week) or a combination mRNA-2752 and immune checkpoint inhibitor will be given up to 4 occasions, 3 weeks apart (+/- 1 week). The participants will proceed to biopsy, either image guided or excisional or partial mastectomy.

Biological: Intralesional mRNA 2752

No active treatment

NO INTERVENTION

The control group will proceed to surgery alone within a 4 month timeframe following the diagnosis of high risk DCIS.

Eligibility Criteria

Age18 Years+
Sexfemale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Plan on having surgical treatment to remove the lesion
  • Have at least 2 of the following high-risk features associated with DCIS - high-grade (grade II-III), palpable mass, hormone receptor negative (less than 1%), Her2 positive, young age (less than 45 years old), and large size (greater than 5 cm) and abundant T cell infiltration.
  • Participants with extensive DCIS and a small component of invasive disease are eligible as long as the extent of invasive disease is 10% or less of the total burden of disease.
  • Participants 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 3 months of treatment initiation):
  • 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).
  • 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.
  • Serum total bilirubin \<=1.5 x ULN OR

  • 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.

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-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.
