Viral Therapy In Treating Patients With Recurrent or Metastatic Squamous Cell Carcinoma of the Head and Neck Cancer or Metastatic Breast Cancer


About this study

This phase I trial studies the side effects and the best dose of viral therapy in treating patients with squamous cell carcinoma of the head and neck that has returned (come back) after a period of improvement or has spread to other parts of the body or breast cancer that has spread to other parts of the body. A virus called encoding thyroidal sodium iodide symporter, which has been changed in a certain way, may be able to kill tumor cells without damaging normal cells.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Inclusion Criteria:

  • Pathologically confirmed squamous cell carcinoma of the head and neck OR pathologically confirmed invasive breast adenocarcinoma with documented estrogen receptor (ER)/progesterone receptor (PR)/human epidermal growth factor receptor 2 (HER2) status and radiographic evidence of distant metastatic disease
  • Measurable disease
  • Head and neck cancer OR metastatic breast for which standard therapy is not curative *NOTE: Patients with ER/PR positive, HER2 negative breast cancer must have progressed through at least one prior cytotoxic regimen for advanced disease and no longer be candidates for standard endocrine therapy; patients with HER2 positive breast cancer irrespective of ER/PR status must have received or no longer be candidates for standard HER2 directed therapy (i.e., trastuzumab, pertuzumab, trastuzumab emtansine, and lapatinib); patients with ER/PR/HER2 negative breast cancer must have progressed through at least one prior cytotoxic regimen for advanced disease; ER/PR and HER2 status are defined by current American Society of Clinical Oncology (ASCO)/College of American Pathologists (CAP) guidelines
  • Patient may have more than one site of recurrence/metastatic disease but only one lesion will be injected that is ≥1 cm in size (if in the lung, the lesion must be ≥2 cm and adjacent to the pleura in the lung)
  • Absolute neutrophil count (ANC) ≥1500
  • Platelet (PLT) ≥ 100,000
  • Hemoglobin (HgB) > 9.0 g/dL
  • Total bilirubin ≤ institutional upper limit of normal (ULN)
  • Serum glutamic oxaloacetic transaminase (SGOT) (aspartate aminotransferase [AST]) ≤ 1.5 x ULN

Exclusion Criteria:

  • Any of the following * Pregnant women * Nursing women * Men or women of childbearing potential who are unwilling to employ adequate contraception during treatment and 8 weeks following the completion of treatment
  • Co-morbid systemic illnesses or other severe concurrent disease which, in the judgment of the investigator, would make the patient inappropriate for entry into this study or interfere significantly with the proper assessment of safety and toxicity of the prescribed regimens
  • Receiving therapeutic anticoagulation (Coumadin or low molecular weight heparin)
  • Active infection ≤ 5 days prior to registration
  • History of tuberculosis or history of tuberculin purified protein derivative (PPD) positivity
  • Any of the following prior therapies: * Chemotherapy ≤ 3 weeks prior to registration * Immunotherapy ≤ 4 weeks prior to registration * Biologic therapy ≤ 4 weeks prior to registration * Radiation therapy ≤ 3 weeks prior to registration
  • Failure to fully recover from acute, reversible effects defined as ≤ grade 1 Common Terminology Criteria for Adverse Events (CTCAE) version (v.) 4.0 of prior chemotherapy regardless of interval since last treatment
