Study Description

Brief Summary

Malignant glioma are the most common and aggressive primary brain tumors in adults. Despite advances in multimodal treatment including surgery, radiation and chemotherapy, most patients have a dismal prognosis of 9-15 months (Stupp et al., NEJM 2005).

A major reason for the aggressiveness of malignant glioma is a pronounced tumor neovascularization, mainly driven by the vascular endothelial growth factor (VEGF) and its receptors. The therapeutic monoclonal antibody Bevacizumab (Avastin®) inhibits the VEGF pathway by binding the VEGF ligand. In Magnetic Resonance Imaging (MRI) this treatment reduces contrast enhancement by restoring both, the blood-brain-barrier and the destabilized vessel integrity. Furthermore, it raises the sensitivity of co-administered chemotherapeutics such as Irinotecan. In conclusion, anti-angiogenic therapy leads to the problem that the routinely used MRI techniques cannot distinguish anti-vascular effects from true anti-tumor effects.

The study hypothesis of the clinical trial part is that in 35% of malignant glioma patients Avastin / Irinotecan chemotherapy results in objective tumor responses assessed by standard / functional MRI and FET- /FLT-PET neuroimaging. The study hypothesis for the translational study part is that the expression of the molecular targets of Avastin and Irinotecan in malignant glioma tissue ( = tumor and vascular cells) are predictive for Avastin / Irinotecan therapy induced treatment response measured by functional MRI and FET- / FLT-PET imaging.

Eligibility Criteria

Criteria

Ages Eligible for Study:

18 Years and Older

Sexes Eligible for Study:

All

Accepts Healthy Volunteers:

Inclusion Criteria:

Patients present with a first or second tumor recurrence / progression of a histological confirmed supratentorial malignant glioma WHO Grade III-IV (Classification following WHO criteria).
Patients with surgical resection of tumor recurrence / progression: Following standard therapy(first recurrence) or standard therapy / second line chemotherapy (second recurrence, excepting antiangiogenic approaches) patients must have evidence of further tumor progression measured by standard MRI sequences (MacDonald criteria). If possible, patients may have prior surgical resection of the tumor progression and will be eligible if the following conditions apply:

Patients must have recovered from the effects of surgery
To adequately asses the malignant glioma before surgery and the extent of residual disease postoperatively, two MRIs scans have to be performed:
A first standard MRI scan has to be done within 1 week before surgery to document a progressed or recurrent malignant glioma.
A second standard / functional MRI scan has to be done between 24 and 48 hours after surgery to document the postoperative malignant glioma (Baseline MRI scan).
FET- / FLT-PET scans have to be done within 2 weeks after surgery to document the postoperative malignant glioma (Baseline PET scans).

Patients without surgical resection of the tumor recurrence / progression: Patients must have evidence of tumor progression measured by standard MRI sequences (MacDonald criteria).

Additional functional MRI sequences have to be done within 1 week prior to study enrollment.
FET- / FLT-PET scans have to be done within 2 weeks after surgery to document the postoperative malignant glioma (Baseline PET scans).

Resolution of all acute toxic effects of prior therapy to grade ≤ 1 (except alopecia)
Patients must have an ECOG performance status of 0-2
Patients must be ≥ 18 years and ≤ 80 years of age, with a life expectancy of greater than 8 weeks
Patients must have adequate organ function as defined by the following criteria:

Bone Marrow Reserve

Platelets ≥ 75.000/μL
Absolute Neutrophil Count ≥ 1500/μL
Hemoglobin ≥ 10.0 g/dL Blood Coagulation
aPTT ≤ 1.5 times upper limit of normal (ULN) Hepatic Function
ASAT and ALAT ≤ 2.5 times ULN
ALP ≤ 2.5 times ULN
Total SERUM Bilirubin < 1.5 times ULN Renal Function
SERUM Creatinine ≤ 1.5 times ULN Metabolism
SERUM Albumin ≥ 3.0 g/dL All tests must be performed ≤ 3 days prior to study enrollment. Eligibility for hemoglobin count may be reached by transfusion.

Signed and dated informed consent document by the patient, indicating that the patient has been informed of all the pertinent aspects of the trial prior to study enrollment.
Willingness and ability of the patient to comply with scheduled visits, treatment plans, laboratory tests, and other study procedures.

Exclusion Criteria:

The patient is active participant in another clinical trial, which investigates substances with antiangiogenic effectiveness
Exclusion of patients in the event of

surgery of a recurrent / progressed malignant glioma within 2 weeks prior to study enrollment
chemotherapy (Standard therapy o Second Line Chemotherapy) within 2 weeks prior to study enrollment
radiation therapy (Standard therapy) within4 weeks to study enrollment
evidence in baseline MRI of intratumoral or peritumoral hemorrhage deemed clinically significant by the treating physician (area of hemorrhage > 25% of tumor area)

Significant Co-Morbidities within 12 months prior to study enrollment

myocardial infarction, severe/unstable angina pectoris, coronary/peripheral artery bypass graft, congestive heart failure
cerebrovascular accident including transient ischemic attack

Significant Co-Morbidities at Baseline Evaluation

Hypertension that cannot be controlled by medications (>150/100 mmHg despite optimal medical therapy)
Pulmonary embolism within 4 weeks before study enrollment

Anticoagulation: Current treatment with therapeutic doses of Marcoumar / Sintrom excluding thrombosis prophylaxis with low dose Heparin
Pregnancy, Breastfeeding and Non-Contraception

Female patients who are pregnant or nursing
Patients who are sexually active and unwilling or unable to use a medically acceptable method of contraception during the trial

Evidence of increased intracranial pressure

midline shift > 5 mm
headache, distinct nausea and vomiting

Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that would impart excess risk associated with study participation or study drug administration, or which would make the patient inappropriate for entry into this study. The decision to enroll the patient in this study is in the judgment of the investigator.
