Is NCT05590689 recruiting? Yes, currently enrolling (May 2026). This Phase 1/2 trial studies Gliolan for glioblastoma.

Phase 1/2RecruitingUniversität MünsterNCT05590689Data as of May 2026

Treatment: GliolanThe investigational drug 5-ALA (known under the trade name Gliolan®) is an approved drug for the surgical removal of malignant glioma (WHO grade III and IV). In this trial, the drug is being tested outside of its actual approval as a radiosensitizer in combination with conventional radiotherapy for first-time recurrence (relapse) of malignant glioma. In this clinical trial, the investigational drug 5-ALA is being used for the first time in a multiple dose escalation regimen in combination with radiotherapy following surgical removal of a recurrent malignant glioma in humans. The investigational drug, 5-ALA, has been used as a single dose to date as a standard of care for visualization of malignant tissue in the surgical removal of gliomas. The planned clinical trial will first and foremost investigate how well repeated administration of the investigational drug 5-ALA is tolerated in combination with radiotherapy. At the same time, the design of the trial serves to optimize this novel therapeutic procedure with regard to the frequency of administration of the investigational drug 5-ALA in combination with radiotherapy for future clinical trials. As a secondary objective, the efficacy of additional 5-ALA administration will also be investigated.
