ClinConnect Summary

This clinical trial, called Targeted Pediatric High-Grade Glioma Therapy, is focused on studying brain tumors in children, adolescents, and young adults who have recently been diagnosed with high-grade gliomas, including types like diffuse intrinsic pontine glioma (DIPG) and glioblastoma. The main goal is to analyze the genetic makeup of these tumors through a process called genetic sequencing. This testing helps determine if participants qualify for future treatment trials based on the specific genetic changes found in their tumors.

Eligible participants are those aged 12 months to 30 years who have a newly diagnosed high-grade glioma, confirmed by medical experts. This trial is open to patients regardless of previous treatments or whether their tumors can be measured. If a patient joins the study, they will need to provide a tumor sample or results from prior genetic testing. It’s essential that patients or their guardians give written consent to participate. The trial is currently recruiting participants, and those who enroll can expect a thorough evaluation to help guide their future treatment options based on their tumor's unique characteristics.

Eligibility criteria

• Inclusion Criteria:
• • 1. Age: Patients must be ≥12 months and ≤39 years of age at the time of enrollment onto this screening protocol.
• • 2. Diagnosis: Patients with newly diagnosed HGG, including DIPG are eligible. The diagnosis of HGG must have been confirmed by local pathology review. for the diagnosis of DIPG, patients must have a tumor with pontine epicenter and diffuse involvement of at least 2/3 of the pons, with histopathology consistent with diffuse WHO grade 2-4 glioma (eg, diffuse astrocytoma, anaplastic astrocytoma, glioblastoma, H3K27-altered diffuse midline glioma). For all other tumors, histologic grade must be WHO grade 3-4.
• • 3. Disease Status: There are no disease status requirements for enrollment.
• • Measurable disease is not required. Patients without measurable disease are eligible.
• • Patients with metastatic/disseminated or multifocal disease or gliomatosis cerebri are eligible.
• • Patients with a primary spinal tumor are eligible.
• • Patients with secondary, radiation related HGG are eligible.
• • 4. Prior Therapy for HGG: Surgery, radiation, and/or dexamethasone are permissible. Temozolomide concurrent with radiation is permissible, but not recommended. No other prior anticancer therapy for HGG will be allowed.
• • Timing from surgery to start of RT: For patients who have started RT, radiation must have started within 31 days of definitive surgery or biopsy (if patient had two surgeries, radiation must have started within 31 days from second surgery).
• • 5. Tumor Sample Availability OR results from previous molecular profiling/targeted sequencing
• • If a patient screens through OPTION #1, tumor sample in addition to normal comparator tissue (peripheral blood or saliva) must be submitted for comprehensive molecular screening at the time of screening enrollment.
• • If a patient screens through OPTIONS #2 or #3, results from previously performed molecular profiling must be submitted following enrollment. It is highly recommended that results be uploaded within 7 days of enrollment (if results are available at time of enrollment) or within 7 days of results becoming available (if pending at time of enrollment) to allow adequate time for central review.
• • 6. Informed Consent: All patients and/or their parents or legally authorized representatives must sign a written informed consent. Assent, when appropriate, will be obtained according to institutional guidelines.
• • 7. Enrollment timeline: Patients are eligible to enroll on the TarGeT-SCR anytime between diagnosis and the following specific timepoints post completion of RT
• • Patients screening through OPTION #1 are eligible to enroll anytime between diagnosis and 10 days post RT.
• • Patients screening through OPTIONS #2 or #3 are eligible to enroll anytime between diagnosis and 21 days post RT.
• However, it is important to note the following:
• • For treatment protocols that include targeted therapy administered concurrently with RT, patients must start treatment within 10 calendar days of starting RT.
• • For treatment protocols that only include maintenance/adjuvant therapy (no systemic therapy given concurrently with radiation), patients must start treatment by 35 days post RT
• • #SCREENING OPTIONS
• • OPTION1: Molecular screening through CONNECT TarGeT Clinical Testing Laboratories
• • OPTION2: Molecular screening through a national comprehensive tumor profiling program
• • OPTION3: Clinically validated targeted sequencing or focused profiling
• Exclusion Criteria:
• • -Tumors that do not meet HGG and DIPG diagnoses specified above
