Summary

The primary goal of this prospective clinical trial is to evaluate the safety of PEP-CMV in patients with recurrent medulloblastoma and malignant glioma. Patients with histologically-proven medulloblastoma or malignant glioma who had received prior therapy for their initial diagnosis and subsequently had tumor recurrence/progression may be enrolled any time after recurrence/progression regardless of prior adjuvant therapy. PEP-CMV is a vaccine comprised of Component A, a synthetic long peptide (SLP) of 26 amino acid residues from human pp65. In May 2021, enrollment on the study was temporarily suspended due to delays in vialing the PEP-CMV study vaccine.

Description

Once a patient has enrolled onto this study, prior therapy will be terminated and patients will receive temozolomide 200 mg/m2/day x 5 days. If they are receiving bevacizumab at the time of enrollment, they will continue bevacizumab 10 mg/Kg every 14 days.

Patients who are ≥ 18 years of age will receive a tetanus (Td) booster at the time of enrollment. Immunotherapy begins with a Tetanus (Td) pre-conditioning vaccine delivered intradermally (i.d.) in the right groin at the site of the vaccine injection 6-24 hours prior to the first vaccine on day 21. The PEP-CMV vaccine will be administered as follows: PEP-CMV Component A mixed with Montanide ISA-51 (1:1 volume ratio) intradermally administered half in the RIGHT groin and half in the LEFT groin.

The first 3 PEP-CMV vaccines will occur every 2 weeks, then PEP-CMV vaccines will continue monthly (+/- 2 weeks) for no more than 10 years. Blood will be obtained for immune system monitoring.

In May 2021, enrollment on the study was temporarily suspended due to delays in vialing the PEP-CMV study vaccine.

Eligibility

Yes No Not Sure

Inclusion Criteria

Patients who are 3 - 35 years old
Histopathologically proven previous diagnosis of medulloblastoma or Grade III or IV glioma
Radiology evidence of recurrent medulloblastoma (reMB) or recurrent Grade III and IV glioma. Patients will be considered for a biopsy or resection of the recurrent/progressive tumor at the discretion of the treating neurosurgeon and neuro-oncologist
Brain MRI within one month prior to enrollment
Received prior therapy for their initial diagnosis prior to recurrence/progression or who are unable to receive radiation therapy due to genetic disorders that put them at significant risk for radiation-induced secondary malignancies (i.e. Gorlin's syndrome or NF1 mutation)
Patients with neurological deficits should have deficits that are stable for a minimum of 2 weeks prior to registration
Karnofsky Performance Status (KPS) of ≥ 60% (KPS for > 10 years of age) or Lansky performance Score (LPS) of ≥ 60 (LPS for ≤ 10 years of age) assessed within 2 weeks prior to registration. Patients who are unable to walk because of paralysis but who are up in a wheel chair will be considered ambulatory for the purposes of the performance score

Patients of childbearing or child-fathering potential must be willing to use a
medically acceptable form of birth control, which includes abstinence, while
being treated on this study
Signed informed consent according to institutional guidelines must be obtained prior to registration
Any prior chemoradiotherapy is allowed

Exclusion Criteria

Known immunosuppressive disease or human immunodeficiency virus infection
Patients with active renal, cardiac (congestive cardiac failure, myocardial infarction, myocarditis), or pulmonary disease
Patients receiving concomitant immunosuppressive agents for medical condition
Patients who need definitive radiotherapy for treatment of recurrent MB or recurrent Grade III or IV glioma
Patients receiving any other investigational drug therapy
Patients on corticosteroids > 0.1 mg/Kg/day (i.e. > the maximum dose of 4 mg/day)
Patients with any clinically significant unrelated systemic illness (serious infections or significant cardiac, pulmonary, hepatic or other organ dysfunction)
Patients with inability to return for follow-up visits or obtain follow-up studies required to assess toxicity to therapy
