Radiodynamic Therapy (RDT) With Gliolan in Patients With First Recurrence of Brain Tumor

Ki vehet részt

• 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:; combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation: I. oral II. intravaginal III. transdermal; progestogen only hormonal contraception associated with inhibition of ovulation: I. oral II. injectable III. implantable; intrauterine device (IUD); intrauterine hormone-releasing system (IUS); bilateral tubal occlusion; vasectomised partner; male patients have to use a condom; sexual abstinence
• 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
