H3.3K27M Peptide Vaccine With Nivolumab for Children With Newly Diagnosed DIPG and Other Gliomas
H3.3K27M Specific Peptide Vaccine Combined With Poly-ICLC With and Without PD-1 Inhibition Using Nivolumab for the Treatment of Newly Diagnosed HLA-A2 (02:01)+ H3.3K27M Positive Diffuse Intrinsic Pontine Glioma (DIPG) and Newly Diagnosed HLA-A2 (02:01)+ H3.3K27M Positive Gliomas
This is 3-arm, multicenter study that will be conducted through the Pacific Pediatric Neuro-oncology Consortium (PNOC).
This study will assess the safety and immune activity of a synthetic peptide vaccine specific for the H3.3.K27M epitope given in combination with poly-ICLC and the H3.3.K27M epitope given in combination with poly-ICLC and the PD-1 inhibitor, nivolumab, in HLA-A2 (02:01)+ children with newly diagnosed DIPG or other midline gliomas that are positive for H3.3K27M.

- The effects of the H3.3K27M vaccine and nivolumab on the developing human fetus are unknown. For this reason, females of child-bearing potential and males must agree to use adequate contraception. Adequate methods include: hormonal or barrier method of birth control; or abstinence prior to study entry and for the duration of study participation.

Note: Patients that are currently using inhaled, intranasal, ocular, topical or other non-oral or non-IV steroids are not necessarily excluded from the study but need to be discussed with the study chair.
- Patients with a ≥ Grade 2 hypothyroidism due to history of autoimmunity are not eligible. (Note: Hypothyroidism due to previous irradiation or thyroidectomy will not impact eligibility).
- Patients who have received prior solid organ or bone marrow transplantation are not eligible.
- Patients with uncontrolled infection.
- Female patients of childbearing potential must not be pregnant or breast-feeding. Female patients of childbearing potential must have a negative serum or urine pregnancy test prior to the start of therapy (as clinically indicated).

Intervention / Treatment |
---|---|
Experimental: Stratum A: Newly Diagnosed DIPG
Newly diagnosed children with diffuse intrinsic pontine glioma who are positive for HLA-A2 and the H3.3K27M mutation that underwent radiation therapy will receive the specific H3.3K27M peptide vaccine, combined with the tetanus toxoid (TT) peptide, emulsified in Montanide.

Time Frame |
---|---|---|
Number of Participants with Adverse Events related to treatment
Time Frame: 24 months
|
Safety of the vaccine (Strata A and B) or vaccine in combination with nivolumab (Stratum C) will be assessed by monitoring for adverse events (AEs), scheduled laboratory assessments, vital signs, & physical examinations for subjects who receive the vaccination.
The severity of toxicities will be graded according to the NCI CTCAE v5.0.
AEs & clinically significant lab abnormalities (meeting Grade 3, 4, or 5 criteria according to CTCAE) will be summarized by maximum intensity & relationship to study drug(s).
Grade 1 & 2 AEs will be summarized if related to study therapy.
Descriptive statistics will be utilized to display the data on toxicity seen.

24 months
|
Overall survival (OS) at 12 months (OS12)
Time Frame: 36 months
|
OS12 will be the clinical efficacy primary endpoint for Stratum A. Any eligible subject that receives at least one dose of the K27M/TT vaccine will be considered evaluable for clinical efficacy.
For subjects who are still alive at 12 months, OS12 will be censored at the last contact date.
OS will be estimated using the Kaplan-Meier method.
