Descrizione riassuntiva della sperimentazione (Fonte di dati: BASEC)
Derzeit gibt es keine wirksamen Therapien für pädiatrische maligne Gliome.
Gliome, die innerhalb von Mittellinienstrukturen - wie es bei DIPG der Fall ist- liegen, haben eine besonders schlechte Prognose. Die Immuntherapie, wie z.B. aktive Impfungen, hat das Potenzial, sich zu einer wirksamen und sicheren Modalität für diese Patienten zu entwickeln. Es wird erwartet, dass Impfstoffe, die spezifische Peptide verwenden, im Vergleich zu ganzen Gliom-abgeleiteten Antigenen besser durchführbar sind, da diese Impfstoffe Gliom-spezifische Immunantworten induzieren können, ohne dass theoretische Bedenken hinsichtlich einer Autoimmunenzephalitis bestehen. Darüber hinaus können diese Impfstoffe dank der Verwendung von synthetischen Antigenpeptiden und Montanid ISA-51 "von der Stange" hergestellt werden. Die Verwendung modifizierter Peptide (Peptide, in denen Aminosäurereste aus der Wildtyp-Sequenz ersetzt werden) kann es uns ermöglichen, in ganzen Gliomzellen effizientere T-Zell-Antworten als natürliche Antigene zu induzieren. Auf der Grundlage kürzlich veröffentlichter Labordaten hat die Verabreichung von Poly-ICLC zusammen mit den synthetischen Peptiden die Induktion von antipeptidzytotoxischen T-Lymphozyten (CTL) und den Transfer von antigenspezifischen T-Zellen zu den Hirntumorstellen bemerkenswert verbessert.
Wir stellen die Hypothese auf, dass die Kombination der PD-1-Hemmung mit dem H3.3K27M-spezifischen Peptidimpfstoff die Aktivität des Peptidimpfstoffs verbessern wird, indem die Reaktion der peptidgeprimten T-Zellen gegen den Tumor verstärkt wird.

Gender: All
Maximum age: 21 Years
Minimum age: 3 Years
Inclusion Criteria:
- Stratum A:
? Newly diagnosed children (3-21 years old) with DIPG who are positive for the
H3.3K27M mutation (positive testing in Clinical Laboratory Improvement Amendments
(CLIA) laboratory) that underwent standard radiation therapy.
- Stratum B:
? Newly diagnosed children (3-21 years old) with diagnosis of glioma other than DIPG
who are positive for the H3.3K27M mutation (positive testing in CLIA laboratory)
including spinal cord gliomas that underwent standard radiation therapy.
- Stratum C:
- Newly diagnosed children 3-21 years of age with diagnosis of DIPG or midline
glioma other than DIPG (excluding primary spinal cord gliomas) who are positive
for the H3.3K27M mutation (positive testing from a CLIA or equivalent laboratory
required), that underwent standard radiation therapy.
The following eligibility criteria apply to strata A, B and C:
- The patient must test positive for HLA-A*02:01 (positive testing from a CLIA or
equivalent laboratory required; only the HLA A*02:01 subtype is eligible; other
subtypes are excluded)
- The patient must be either off systemic steroids or be on stable dose of dexamethasone
or equivalent (max 0.1 mg/kg/day; maximum 4mg/day) at time of enrollment.
- Patients must not have received any prior chemotherapy, immunotherapy or bone marrow
transplant for the treatment of their tumor. Prior use of temozolomide during
radiation at maximum of the standard pediatric dosing (defined as 90 mg/m^2/dose
continuously during radiation therapy for 42 days) or dexamethasone is allowed.
- Patients must have undergone radiation therapy and surgery as part of their standard
of care.
- Stratum A: Radiation therapy must have started within 4 weeks of diagnosis by
imaging or surgery, whichever is later.
- Stratum B: For subjects undergoing surgery for more extensive resection,
radiation therapy should be started within 4-6 weeks from surgery.
- Stratum C: Radiation therapy must have started within 4 weeks of diagnosis by
imaging or surgery, whichever is later. For subjects undergoing surgery for more
extensive resection, radiation therapy should be started within 4-6 weeks from
surgery.
- Karnofsky = 50 for patients = 16 years of age, and Lansky = 50 for patients < 16 years
of age (See Appendix A). Patients who are unable to walk because of paralysis, but who
are up in a wheelchair, will be considered ambulatory for the purpose of assessing the
performance score.

- Platelet count = 100,000/mm3 (transfusion independent, defined as not receiving
platelet transfusions for at least 7 days prior to enrollment).
Adequate Renal Function Defined as:
- Creatinine clearance or radioisotope glomerular filtration rate (GFR) = 70 mL/min/1.73
m2 or
