About
The 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.

Inclusion criteria
Written patient consent after comprehensive information
Age >/= 18 years
Recurrence of supratentorial glioblastoma after initial resection and adjuvant therapy (e.g. radio-chemotherapy, targeted therapies, antiangiogenic therapies as determined by the tumor board) (with planned second resection cohort 0 and 1), second or third recurrences permitted
Clinically indicated further radiotherapy as per decision of the tumor board as part of therapy for recurrence
Histological verification of recurrent glioblastoma independent of methylated MGMT promotor status when alkylating chemotherapy failed at this time.
Karnofsky Performance Score ≥ 60
For female and male patients and their female partners of childbearing/reproductive potential(*): Willingness to apply highly effective contraception (Pearl index <1) during the entire study (and for at least 6 months after the first application of 5-ALA). Such methods include:
Pre-menopausal(*) female patients with childbearing potential: a negative pregnancy test must be obtained max. 72h prior to treatment start
Adequate liver function: bilirubin < 1.5 times above upper limit of normal range (ULN), alanine transaminase (ALT/SGPT) and aspartate transaminase (AST/SGOT) < 3 times ULN. In the case of documented or suspected Gilbert's disease bilirubin < 3 times ULN.
Adequate renal function: creatinine < 3 times above ULN; eGFR >/= 60 ml/min, Blood clotting: INR/Quick/PT and PTT within acceptable limits according to the investigator.
(*) Definition: A man is considered of reproductive potential after puberty unless permanently sterile by bilateral orchidectomy. A woman is considered of childbearing potential (WOCBP), i.e. fertile, following menarche and until becoming post-menopausal unless permanently sterile. Permanent sterilisation methods include hysterectomy, bilateral salpingectomy and bilateral oophorectomy. A post-menopausal state is defined as no menses for 12 months without an alternative medical cause. A high follicle stimulating hormone (FSH) level in the postmenopausal range may be used to confirm a post-menopausal state in women not using hormonal contraception or hormonal replacement therapy. However in the absence of 12 months of amenorrhea, a single FSH measurement is insufficient.
