Imiquimod/Brain Tumor Initiating Cell (BTIC) Vaccine in Brain Stem Glioma

Stopped early · Phase 1

Conditions studied: Diffuse Intrinsic Pontine Glioma

In brief

This is a pilot/feasibility study. The study design represents a modification of current standard of care for Diffuse Intrinsic Pontine Glioma (DIPG) (5580 cGY involved field radiation), with the final two doses of radiation given at intervals during the vaccination phase of treatment. Patients between the ages of 3 years and 25 years diagnosed with Diffuse Intrinsic Pontine Glioma (DIPG) will be allowed to participate in the trial. Study enrollment will occur after the completion of conformal radiation therapy to a dose of 5580 cGy and the post radiation therapy (RT) magnetic resonance imaging (MRI) shows no disease progression. Three patients with glioblastoma multiforme, aged 16 years and older, will be entered first to confirm vaccine safety before enrolling DIPG patients.

Who can join

Age: 3 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Age 16 years or older patients with histologically confirmed glioblastoma multiforme (GBM) World Health Organization (WHO) grade III-IV with recurrent or progressive disease after standard therapy (enrollment plan 1).
• Age 3 years and older patients with diffuse intrinsic pontine glioma (DIPG) diagnosed by magnetic resonance imaging (MRI). Completion of standard radiation therapy (not to exceed 5580 cGy) with a post radiation therapy (RT) MRI that shows no disease progression when compared with pre-RT MRI. All patients must be treated with Intensity Modulated Radiation Therapy (IMRT) or an equivalent conformal technique. Patients from an outside institution who are referred after the start of radiation therapy may complete initial radiation therapy at their home institution as long as dosage guidelines are met and the total dose does not exceed 5580 cGy at the time of study registration (enrollment plan 2 and 3).
• all patients regardless of diagnosis must be clinically stable and off or on low dose (no more than 0.1 mg/kg/day, maximum of 4 mg/day dexamethasone) corticosteroid for at least 1 week prior to study enrollment.

You may not qualify if…

• Pregnant or breast-feeding. Pregnancy testing will be performed on all menstruating females within 14 days prior to 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 chemotherapy, investigational agents or registration on another therapy based trial or received chemotherapy with radiation therapy
• History of immune system abnormalities such as hyperimmunity (e.g., autoimmune diseases) and hypoimmunity (e.g., myelodysplastic disorders, marrow failures, AIDS, ongoing pregnancy, transplant immunosuppression)
• Any isolated laboratory abnormality suggestive of a serious autoimmune disease
• Any conditions that could potentially alter immune function (AIDS, multiple sclerosis, diabetes, renal failure)
• Receiving ongoing treatment with immunosuppressive drugs, excluding those patients requiring dexamethasone for treatment of tumor-related edema
