Stereotactic Biopsy Split-Course Radiation Therapy - Diffuse Midline Glioma (SPORT-DMG)

Trial ID: NCT05077735

Interventional - Phase 2 - Active, not recruiting

This phase II trial studies the clinical outcomes of hypofractionated radiation therapy in patients with diffuse midline gliomas. This study aims to change the way radiation is delivered, from giving 6 weeks of radiation all at once to giving 2 weeks of radiation. This may determine if there is a difference in the outcome of the treatment, and most importantly, the patients' quality of life.

Conditions

• Diffuse Midline Glioma, H3 K27M-Mutant

Interventions

• Hypofractionated Radiation Therapy
• Questionnaire Administration
• Magnetic Resonance Imaging
• Computed Tomography Scan

Eligibility

Inclusion criteria

• Age \>= 1 year(s) old (no maximum age)
• Radiologic appearance of diffuse midline glioma of the pons, including diffuse infiltration of \>= 50% of the pons on MRI, with or without extension to the midbrain and/or medulla oblongata with at least 1 of the 3 brainstem symptoms (cranial nerve deficit, long tract sign, or cerebellar sign)
• If all features of this clinicoradiologic criteria are met, then patients can continue on protocol with or without a biopsy
• If all features of this clinicoradiologic criteria are not met, patients must receive a brainstem lesion biopsy to be treated on protocol. If this cannot be completed, patients will be withdrawn from the study
• If biopsy has already been completed at an outside institution, the outside pathology report will be reviewed ahead of trial enrollment. The pathology specimen will then be sent to Mayo Clinic for further review, but will not delay study enrollment
• Able to undergo MRI Brain
• Negative urine pregnancy test completed =\< 7 days prior to registration, for women of childbearing potential only
• Primary language of English or Spanish for patients and their caregiver
• Patient or caregiver willing and able to provide written informed consent
• Caregiver able to complete questionnaires by themselves or with assistance
• Willing to return to enrolling institution for follow-up during the active monitoring phase of the study

Exclusion criteria

• Any patient who has received previous radiation to the brain
• Any patient who has received previous chemotherapy
• Any patient with a diagnosis of neurofibromatosis type 1 or 2 (NF1 or NF2)
• Any of the following:
• Pregnant women
• Nursing women
• Women of childbearing potential who are unwilling to employ adequate contraception
• Co-morbid systemic illnesses or other severe concurrent disease which, in the judgment of the investigator, would make the patient inappropriate for entry into this study or interfere significantly with the proper assessment of safety and toxicity of the prescribed regimens
• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
• Other active malignancy =\< 5 years prior to registration. EXCEPTIONS: Non-melanotic skin cancer, breast cancer, prostate cancer, well-differentiated thyroid cancer, carcinoma-in-situ of the cervix
• NOTE: If there is a history or prior malignancy, they must not be receiving other specific treatment for their cancer
• Patients \> 16 years with an Eastern Cooperative Oncology Group (ECOG) score \>= 4 and patients =\< 16 years with a Lansky play scale =\< 20
• NOTE: All novel therapeutic interventions, including but not limited to dordaviprone, are allowed for patients who enroll on the clinical trial
