- Female subject 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 must be willing to use an adequate method of contraception.
Note: Abstinence is acceptable if this is the usual lifestyle and preferred contraception for the subject.
- Male subjects of childbearing potential must agree to use an adequate method of contraception.
- Ability to return to Duke University Medical Center for adequate follow-up as required by this protocol.
Exclusion Criteria:
- Patients in this study, may not receive cytotoxic chemotherapy, anti-estrogen therapy, targeted small molecule therapy, or radiation therapy in the 3 weeks before the first infusion of Pembrolizumab, during the injection period for VRP-HER2 and infusion period for Pembrolizumab or for at least 2 weeks after booster immunization with VRP-HER2 (Arm 1) or who has not recovered (i.e., ≤ Grade 1 or at baseline) from adverse events due to a previously administered agent.
- Patients may have received prior radiation including for brain metastases.
- Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis. Subjects with previously treated brain metastases may participate provided they are stable (without evidence of progression by imaging for at least 3 months prior to the first dose of trial treatment and any neurologic symptoms have returned to baseline), have no evidence of new or enlarging brain metastases, and are not using steroids for at least 7 days prior to trial treatment.
- Is currently participating and receiving study therapy or has participated in a study of an investigational agent and received study therapyor 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. Prior history of autoimmune thyroiditis or vitiligo is permitted.
- Has a known history of active TB (Bacillus Tuberculosis)
- Hypersensitivity to pembrolizumab or any of its excipients.
- Has had a prior anti-cancer monoclonal antibody (mAb) within 4 weeks prior to study Day 1 or who has not recovered (i.e., ≤ Grade 1 or at baseline) from adverse events due to agents administered more than 4 weeks earlier.
- 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.
- Has history of (non-infectious) pneumonitis that required steroids or active, non-infectious pneumonitis.
- Has an active infection requiring systemic therapy or systemic use of antimicrobials within 72 hours prior to the first study treatment
- 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 received prior therapy with an anti-PD-1, anti-PD-L1, or anti-PD-L2 agent.
- Hypersensitivity to pembrolizumab or any of its excipients.
- Has a known history of Human Immunodeficiency Virus (HIV) (HIV 1/2 antibodies).
- Has known active Hepatitis B (e.g., HBsAg reactive) or Hepatitis C (e.g., HCV RNA is detected).
- Has received a live vaccine within 30 days of planned start of study therapy.
