PEP-CMV Vaccine Targeting CMV Antigen to Treat Newly Diagnosed Pediatric HGG and DIPG and Recurrent Medulloblastoma

Is NCT05096481 recruiting? Yes, currently enrolling (Sep 2026). This Phase 2 trial studies multiple treatments including PEP-CMV and Tetanus Diphtheria Vaccine for high grade glioma.

Phase 2RecruitingNationwide Children's HospitalNCT05096481Data as of Sep 2026

Treatment: PEP-CMV · Temozolomide · Tetanus Diphtheria VaccineThis study will address the question of whether targeting CMV antigens with PEP-CMV can serve as a novel immunotherapeutic approach in pediatric patients with newly-diagnosed high-grade glioma (HGG) or diffuse intrinsic pontine glioma (DIPG) as well as recurrent medulloblastoma (MB). PEP-CMV is a vaccine mixture of a peptide referred to as Component A. Component A is a synthetic long peptide (SLP) of 26 amino acid residues from human pp65. The SLPs encode multiple potential class I, class II, and antibody epitopes across several haplotypes. Component A will be administered as a stable water:oil emulsion in Montanide ISA 51.
