Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The REMIT (RE-irradiation of diffuse MIdline glioma paTients) study evaluates safety and the palliative efficacy of re-irradiation of patients with diffuse midline glioma (DMG). The study will introduce a standard re-irradiation treatment schedule for DMG patients who have progressed following primary treatment.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

REMIT is a non-randomized, prospective, investigator-initiated, phase II, multi-centre observational study with two inclusion groups, arm A and B. Arm A and B will be offered the same treatment.

Patients treated with primary radiotherapy 54Gy/30 fractions, either enrolled in the BIOMEDE 2.0 protocol or not, will be included in Arm A. DMG patients treated with any other total dose and fractionation than 54Gy/30F will be included in Arm B. The re-RT and follow up will be the same in both arms.

As treatment 20Gy/10 fractions is given as first time re-irradiation with extended follow up on toxicity, performance status and quality of life.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Diffuse midline glioma diagnosis: verified radiologically or histologically Biopsy is not mandatory for REMIT
* Age ≥ 12 months to ≤21 years.
* Min. 180 days/6 months have elapsed from the first day of the 1st RT course
* 1st course of radiotherapy
* Full recovery from all acute and subacute toxicities of 1st RT course
* Clinical progression of symptoms and/or radiographic progression
* Karnofsky performance status scale or Lansky Play Scale \> 50% The performance status should not take the neurological deficits per se into account.

NB: Children and adults with a worsening performance status due to glioma-related motor deficit can be included.

* Life expectancy \> 12 weeks after start of reRT
* Signed informed consent by patient and/or parents or legal guardian

Exclusion Criteria

* Presence of leptomeningeal spread or multifocal disease on MRI at progression
* Other co-morbidity that according to the treating physician would impair participation in the study
* \>1 course of radiotherapy
* Neurofibromatosis type 1
* Inability to complete the medical follow-up (geographic, social, or mental reasons)
