Beskrivelse
Inclusion Criteria:
- Aged 3 to ≤ 21 years.
- Diagnosis of diffuse midline glioma (DMG), including diffuse intrinsic pontine glioma (DIPG), based on characteristic magnetic resonance imaging (MRI) findings and/or histopathologic confirmation.
- Prior radiation treatment must have included focal radiation therapy per institutional standard of care and must have been initiated within 6 weeks of diagnosis.
- At least 4 weeks, but no more than 12 weeks, post-completion of radiotherapy treatment.
- A standard of care post-radiation magnetic resonance imaging (MRI) performed 4 to 6 weeks after radiation therapy is required for confirmation of eligibility.
- Performance status [Karnofsky Performance Scale or Lansky Performance Score] within 14 days of Day 1 ≥ 60.
- Absence of other significant medical condition.
- A legal parent/guardian and/or participant must be able to understand and be willing to sign a written informed consent and/or assent document, as appropriate.
Exclusion Criteria:
- Untreated symptomatic hydrocephalus at the time of consent, has metastatic or disseminated disease, or leptomeningeal disease.
- Magnetic resonance imaging (MRI) findings that preclude stereotactic procedure.
- Intercurrent illnesses or conditions which preclude participation: active systemic infections, autoimmune disease requiring systemic immunomodulation, active or uncontrolled seizure disorder, central nervous system (CNS) vasculopathy or aneurysms, Grade ≥3 cardiac dysfunction, Fridericia-corrected QT interval (QTcF) ≥470 ms.
Abnormal organ function:
- Renal insufficiency: glomerular filtration rate (GFR) ≤ 60 mL/min/1.73m² (with Schwartz equation)
- Hepatic dysfunction: aspartate aminotransferase (AST) / alanine aminotransferase (ALT) ≤ 1.5 x upper limit of normal (ULN) and 3 x upper limit of normal (ULN) in the presence of liver metastases; or bilirubin ≤ 1.5 x upper limit of normal (ULN) and 3 x upper limit of normal (ULN) in the presence of Gilbert disease
Bone marrow suppression:
- absolute neutrophil count (ANC) < 1,000/μL
- platelets < 100,000/μL
- Coagulopathy or international normalized ratio (INR) > 1.5
- Receiving any anticoagulants or antiplatelet drugs; any drugs known to cause ototoxicity and nephrotoxicity; receiving any other tumor-directed therapy.
- Known allergy or hypersensitivity to the study agent (including cisplatin and diluent components).
- Female participants of childbearing potential must not be pregnant or breast-feeding.

Eksperimentel: LSAM-Cisplatin 6 mg/mL
Phase 1 (Dose Escalation): Intratumoral infusion of LSAM-Cisplatin 6 mg/mL using sequential, dose escalating cohorts. Phase 2 (Dose Expansion): Intratumoral infusion of LSAM-Cisplatin 6 mg/mL at the recommended Phase 2 dose (RP2D). |
Participants with diffuse midline glioma (DMG), including diffuse intrinsic pontine glioma (DIPG), will receive a single intratumoral infusion of LSAM-Cisplatin 6 mg/mL via MRI-guided delivery at an infusion rate of 5 µL/min. Phase 1 (Dose Escalation): Participants will be enrolled sequentially into one of six dose levels. Volumes being delivered will range from 27 to 296 µL over a time period of 5 to 59 minutes. Phase 2 (Dose Expansion): Participants will receive LSAM-Cisplatin 6 mg/mL at the recommended Phase 2 dose (RP2D) selected based on the safety and tolerability findings from the dose-escalation phase. |
