Summary

This trial will study whether the PEP-CMV vaccine can help treat high-grade glioma, diffuse intrinsic pontine glioma, and recurrent medulloblastoma in children.

Who is the study for?

This trial is for pediatric patients aged 3-25 with high-grade glioma (HGG), diffuse intrinsic pontine glioma (DIPG), or recurrent medulloblastoma. They must have a confirmed diagnosis, measurable disease on MRI, and stable neurological deficits if present. Prior radiotherapy is required unless they're under 4 years old.

What is being tested?

The study tests PEP-CMV vaccine targeting CMV antigens in children with brain tumors like HGG, DIPG, and recurrent medulloblastoma. It explores the potential of this novel immunotherapy approach combined with Temozolomide chemotherapy and Tetanus Diphtheria Vaccine.

What are the potential side effects?

Possible side effects may include typical vaccine reactions such as pain at the injection site, fever, fatigue, headache, muscle or joint pain. Since it's an investigational therapy specific to cancer treatment side effects are monitored closely.

Experimental Treatment

Group I: PEP-CMVExperimental Treatment3 Interventions

Participants will receive standard chemotherapy with temozolomide for five days, followed by the study vaccine, PEP-CMV, on day 21. Participants will receive a tetanus diphtheria (Td) booster vaccine and a small dose Td preconditioning vaccine to prepare their immune system to receive their first PEP-CMV vaccine. Participants will receive the first 3 PEP-CMV vaccines every 2 weeks, and after the third vaccine, the rest of the vaccines will be given monthly. The first cycle is 77 days and all subsequent cycles are 28 days. The PEP-CMV vaccine may be received for up to 24 cycles.
