 (submitted: October 18, 2013)
Maximum Tolerated Dose [ Time Frame: 91 Days ]
The primary objective of this trial is to determine the maximum tolerated dose (MTD)(up to a dose of 1x10^9 cfu IV) and characterize the safety profile of ADU-623 vaccine in patients with recurrent WHO Grade III/IV Astrocytomas. The MTD will be defined as the highest dose at which none or one out of 6 patients experiences a dose-limiting toxicity (DLT) that is possibly or probably related to the vaccine.

Current Secondary Outcome Measures  ICMJE
 (submitted: October 18, 2013)
  • Tumor response based on magnetic resonance imaging (MRI) exam [ Time Frame: 24 months ]
    The efficacy of therapy on tumor burden and time to progression will be assessed by MRI.
  • Immune Response [ Time Frame: 91 Days ]
    Innate and adaptive immunologic response will be assessed by looking at changes in cytokines and changes in cellular and humoral immunity.

Descriptive Information
Brief Title  ICMJE Phase I Study of Safety and Immunogenicity of ADU-623
Official Title  ICMJE Phase I Study of Safety and Immunogenicity of ADU-623, a Live-attenuated Listeria Monocytogenes Strain (ΔactA/ΔinlB) Expressing the EGFRvIII-NY-ESO-1 Vaccine, in Patients With Treated and Recurrent WHO Grade III/IV Astrocytomas
Brief Summary This is a study for patients with brain tumors called astrocytic tumors. The study will enroll patients who have received standard treatment. The study will test a vaccine called ADU-623. ADU-623 has not been tested in humans before, so the goal of this study is to see if ADU-623 can be given safely to brain cancer patients and what is the better dose to give patients among the three doses that planned to be tested. This study will also evaluate the length of time before patients' cancer worsens and if ADU-623 helps patients to live longer. The study will also measure the body's immune system response to ADU-623.
Detailed Description This Phase I clinical trial will examine the safety, tolerability and immunogenicity of a novel vaccine approach using a live-attenuated strain of Listeria monocytogenes expressing EGFRvIII and NY-ESO-1 antigens to induce proliferation of memory and effector T cells with the overall goal of promoting an immune response against high-grade astrocytic tumors.

Eligibility Criteria  ICMJE

Inclusion Criteria:

  • Patients with a pathologic diagnosis of WHO Grade III or Grade IV astrocytic tumors that have completed standard of care or with radiographic evidence of progression following standard of care.
  • Tumor tissue blocks available to perform both EGFRvIII and NY-ESO-1 testing
  • Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1 or Karnofsky Performance Status (KPS) 70-100
  • Age 18 years or above
  • Have a life expectancy of more than 12 weeks
  • Laboratory values (performed within 5 days) within designated range.

  • Ability to give informed consent and comply with the protocol.

Exclusion Criteria:

  • Have a known allergy to both penicillin and sulfa

  • Have radiographic or clinically significant pleural effusion.
  • Receipt of prophylactic vaccine within 28 days of study treatment.
  • Unable to avoid close contact with another individual known to be at high risk of listeriosis (e.g., newborn infant, pregnant woman, HIV-positive individual).
  • History of allergy to yeast or any other component of the ADU-623 vaccine (e.g., glycerol).
  • Have an immunodeficiency disease or immunocompromised state (e.g., use of immunosuppressive agents; chemotherapy or radiation therapy within 14 days of study treatment).
  • Have had major surgery or significant traumatic injury occurring within 28 days before treatment administration or anticipated surgery or procedure requiring general anesthesia during study participation (including 28 days after last dose of ADU-623).

  • Have received an investigational product within 28 days of study treatment or planned to receive within 28 days after vaccine administration.
  • Have an unhealed surgical wound.

  • Have valvular heart disease that requires antibiotic prophylaxis for prevention of endocarditis.

  • Have insufficient peripheral venous access to permit completion of the study dosing and compliance with study phlebotomy regimen.
  • Have received a diagnosis of HIV, HCV, or HBV (patients with hepatitis C antibody positive may be enrolled if they are confirmed with negative viral load at screening).
  • Have an active autoimmune disease or history of autoimmune disease requiring systemic steroids or other immunosuppressive treatment.
  • Other medical or psychiatric conditions that in the opinion of the Principal Investigator would preclude safe participation in protocol.
  • Pregnant or lactating women, as treatment has unknown effect on the embryo or child.
  • Patients requiring chronic corticosteroid use will be excluded as this may mask toxic effects related to the vaccine and may prevent the development of effective immune responses following vaccination.
