Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • To evaluate the safety of re-irradiation (reRT)

    The primary endpoint will be the cumulative incidence of grade ≥4 CTCAE (The NCI Common Terminology Criteria for Adverse Events) events measured 4 weeks after the last day of reRT.

    4 weeks after end of re-irradiation

Secondary Outcomes (3)

  • The key secondary objective is to prospectively validate the palliative efficacy of reRT of DMG. Palliative efficacy is evaluated by two endpoints: overall survival and symptom relief.

    4 weeks after end of re-irradiation

  • Palliative efficacy measured as symptom relief

    4 weeks after end of re-irradiation

  • Other secondary outcomes

    through study completion

Eligibility Criteria

Age12 Months - 21 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • 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
  • st 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

You may not qualify if:

  • 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)
