Inclusion criteria

  • Radiological suspicion of a malignant glioma with distinct ring- or garland shaped, contrast agent-enhancing tumour structures and a core area of reduced intensity in the MRI (tumour necrosis)
  • Indication for surgical tumour resection
  • First operation of the tumour, no other tumour-specific pre-treatment
  • Karnofsky Performance Scale 70%
  • Patient's written informed consent
  • Age 18-75 years

Exclusion criteria

Exclusion Criteria:

  • Porphyria, hypersensitivity to porphyrins
  • Renal insufficiency:

    • Creatinine > 2.0 mg/dl
  • Hepatic insufficiency:

    • Bilirubin > 3 mg/dl
    • Quick test \< 60 %
    • GT > 100 U/I
  • Other known malignancy (except basaliomas)

Women:

  • Existing/planned pregnancy (to be checked by a pregnancy test if of child-bearing age)/lactation or inadequate contraception (hormone cycle regulation pill or condom)

Men:

  • Inadequate contraception (condom)
  • Dementia or mental condition making it impossible to understand the therapy and therefore prohibiting written consent
  • Simultaneous participation or participation in another clinical trial in the preceding 30 days

What researchers measure

Primary outcomes

  1. Detection of a dose-efficacy relationship between the dose levels and the extent and quality of fluorescence in the tumour core (of newly diagnosed malignant glioma).

    After completion of resection, global fluorescence extent in the tumour core will be assessed by the first and second surgeon. It will be estimated whether approx. 0/3, 1/3, 2/3 or 3/3 of the tumour core is identified using standard white operation light were fluorescent (irrespective of fluorescence quality). The global quality of Gliolan induced tissue fluorescence within the tumour core will be recorded as being strong, weak or missing. As an objective control of the subjective assessment of the fluorescent quality, selected areas will be measured spectrometrically.

    Time frame: Within 3 hours

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 23, 2016, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
