Phase I Study of Safety and Immunogenicity of ADU-623

Study Purpose

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.

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

No
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

More Inclusion & Exclusion Criteria

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.
  • - For women and men of childbearing potential, an acceptable method of highly effective contraception.
  • - Ability to give informed consent and comply with the protocol.

Exclusion Criteria:

  • - Have a known allergy to both penicillin and sulfa.
  • - Have artificial (prosthetic) joint(s), orthopedic screw(s), metal plate(s) or other exogenous implant(s) or device(s) that cannot be easily removed (i.e., prosthetic heart valves).
  • - Have any evidence of hepatic cirrhosis or clinical or radiographic ascites.
  • - 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).
  • - Use of more than 4 grams per day of acetaminophen.
  • - 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 clinically significant heart disease (such as uncontrolled angina, myocardial infarction with the last 3 months, congestive heart failure of New York Heart Association III or IV).
  • - Have valvular heart disease that requires antibiotic prophylaxis for prevention of endocarditis.
  • - Have an intercurrent illness that is either life-threatening or of clinical significance such that it might limit compliance with study requirements including, but not limited to, ongoing or active infection, metabolic or neurological disease, peripheral vascular disease or psychiatric illness.
  • - 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.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT01967758
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

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.
