Vaccination With Dendritic Cells Loaded With Brain Tumor Stem Cells for Progressive Malignant Brain Tumor
Completed · Phase 1
Conditions studied: Brain Tumor, Glioblastoma, Medulloblastoma, Ependymoma, Anaplastic Astrocytoma
In brief
This is a single center Phase I study to determine the safety and maximum tolerated dose (MTD) of autologous dendritic cells (DCs) loaded with allogeneic brain tumor stem cells administered as a vaccination in children and adults with recurrent brain tumors. Once the MTD has been determined, we will conduct a phase II study to determine efficacy. Clinical trials that utilize DCs for immunotherapy have demonstrated significant survival benefit for patients who exhibit robust immune responses against tumor cells. Unfortunately, at the present time the majority of tumor patients are unable to mount an adequate immune response and thus succumb to their tumors. We postulate that the inability to generate an appropriate immune response in these patients is due to a lack of sufficient numbers of appropriate T cells due to an inadequate source of tumor antigens.

You may qualify if…
- Histologically confirmed brain tumors (glioblastoma multiforme, anaplastic astrocytoma, medullo
- Age 0 through 17 years (pediatric subjects), and 18 years and above (adult subjects)
- Lansky score of ≥ 60 (0-15 years) or Karnofsky (16 years or older) performance score of ≥ 60%
- Adequate organ function within 14 days of study registration including the following:
- Adequate bone marrow reserve: absolute neutrophil (segmented and bands) count (ANC) ≥ 1.0 x 10\^9/L, platelets ≥100 x 10\^9/L; hemoglobin ≥ 8 g/dL
- Hepatic: bilirubin ≤1.3 mg/dL or 0-22 mmol/L, aspartate transaminase (AST) and alanine transaminase (ALT) < 3 x upper limit of normal (ULN)
- Renal: Normal serum creatinine for age (below) or creatinine clearance >60 ml/min/1.73 m\^2.
- Sexually active women of child bearing potential must agree to use adequate contraception (diaphragm, birth control pills, injections, intrauterine device [IUD], surgical sterilization, subcutaneous implants, or abstinence, etc.) for the duration of the vaccination period. Sexually active men must agree to use barrier contraceptive for the duration of the vaccination period.
- Willingness to travel to participate in study if from outside local region.
- Voluntary written informed consent must be obtained from all patients (if of assent age) and their parents or legal guardians before performance of any study-related procedure not part of normal medical care, with the understanding that consent may be withdrawn by the subject at any time without prejudice to future medical care.
You may not qualify if…
- Pregnant or breast-feeding. Pregnancy testing will be performed on all menstruating females within 14 days of study enrollment.
- Uncontrolled intercurrent illness including, but not limited to ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, or psychiatric illness/social situations that would limit compliance with study requirements.
- Currently receiving any other investigational agents.
- History of immune system abnormalities such as hyperimmunity (e.g., autoimmune diseases) and hypoimmunity (e.g., myelodysplastic disorders, marrow failures, AIDS, ongoing pregnancy, transplant immuno-suppression).
- Any conditions that could potentially alter immune function (e.g., AIDS, multiple sclerosis, diabetes, renal failure).
