This is an interventional treatment trial for Glioblastoma Multiforme focused on measuring axitinib, glioblastoma, recurrent Read More

1. Histopathological diagnosis of glioblastoma (= WHO grade IV glioma of the central nervous system); both "de novo" and "secondary" glioblastoma are eligible;
2. Diagnosis of glioma recurrence or progression following prior treatment with surgery, radiation therapy and alkylating chemotherapy (defined as significant [according to the investigators individual assessment] growth or recurrence of the glioblastoma demonstrated on sequential Gd-MRI before the time of recruitment).

3. The following disease characteristics should be present:

   1. Presence of a measurable tumor lesion that is characterized by gadolinium enhancement on T1-MRI of the brain (with a longest diameter of > 10 mm);
   2. Enhancing characteristics of the glioblastoma as compared to the normal brain on 18F-FET PET (patients with a non-enhancing lesion are not eligible);
   3. No evidence of clinically meaningful spontaneous intra-tumoral hemorrhage on baseline MRI-imaging or in the prior disease history;
4. No contraindication for evaluation by Gd-MRI or 18F-FET PET of the brain;
5. Archival glioma tissue must be available for collection and storage in a centralized tumor bank;
6. An interval of at least 3 months (12 weeks) after the end of prior radiation therapy; and an interval of at least 4 weeks after the last administration of cytotoxic drug treatment (6 weeks in case of administration of a nitrosureum or mitomycin C); and an interval of at least 4 weeks after the last administration of any other kind of anti glioblastoma treatment;
7. A stable dose of corticosteroids for at least 14 days before the initiation of study treatment with axitinib;
8. WHO performance status of 0 or 1;
9. Life expectancy of ≥12 weeks;
10. Male or female, 18 years of age or older;
11. Resolution of all acute toxic effects of prior systemic therapy, radiotherapy or surgical procedure to NCI CTCAEv3.0 grade 0 or 1 or back to baseline except for alopecia or hypothyroidism;

12. Adequate organ function as defined by the following criteria:

    • Total serum bilirubin < 1.5 x ULN (patients with Gilbert's disease exempt)
    • AST and ALT < 2.5 x upper limit of normal (ULN);
    • Serum creatinine ≤1.5 x ULN or calculated creatinine clearance ≥60 mL/min
    • Absolute neutrophil count (ANC) > 1500/mm³ without growth factor support
    • Platelets > 75 000 cells/mm³
    • Hemoglobin ≥9 g/dL (which may be obtained by transfusion or growth factor support)
    • Urinary protein <1+ by urine dipstick. If dipstick is ≥1+ then a 24-hour urine collection should be done and the patient may enter only if urinary protein is <2 grams per 24 hours
13. Women of childbearing potential must have a negative serum or urine pregnancy test within 3 days prior to treatment.;
14. Female patients must be surgically sterile or be postmenopausal, or must agree to use effective contraception measures during the period of therapy which should be continued for 4 weeks after the last dose of axitinib. All female patients with reproductive potential must have a negative pregnancy test (serum or urine) prior to enrollment. Male patients must be surgically sterile or must agree to use effective contraception during the period of therapy. The definition of effective contraception will be based on the judgment of the principal investigator or a designated associate;
15. No previous treatment on an axitinib trial;
16. No previous treatment with a VEGF or VEGFR-targeted drug (including, but not limited to bevacizumab, aflibercept, cediranib, sorafenib, sunitinib, XL184, and pazopanib);

17. No gastrointestinal abnormalities including:

    1. Inability to take oral medication.
    2. Requirement for intravenous alimentation.
    3. Prior surgical procedures affecting absorption including gastric resection.
    4. Treatment for active peptic ulcer disease in the past 6 months.
    5. Malabsorption syndromes.
    6. Active gastrointestinal bleeding, unrelated to cancer, as evidenced by hematemesis, hematochezia or melena in the past 3 months without evidence of resolution documented by endoscopy or colonoscopy;
18. No evidence of preexisting uncontrolled hypertension as documented by 2 baseline blood pressure readings taken at least 1 hour apart. The baseline systolic blood pressure readings must be ≤140 mm Hg, and the baseline diastolic blood pressure readings must be ≤90 mm Hg. Patients whose hypertension is controlled by antihypertensive therapies are eligible;

19. No concurrent treatment:

    1. In another therapeutic clinical trial;
    2. With a drug having pro-arrhythmic potential;
    3. With enzyme inducing anti-epileptic drugs (EIAED) within 14 days before dosing with axitinib (e.g. carbamazepine, phenobarbital, phenytoin);
20. No current use or anticipated need for treatment with drugs that are known potent CYP3A4 inhibitors (ie, grapefruit juice, verapamil, ketoconazole, miconazole, itraconazole, erythromycin, telithromycin, clarithromycin, indinavir, saquinavir, ritonavir, nelfinavir, lopinavir, atazanavir, amprenavir, fosamprenavir and delavirdine).
21. No current use or anticipated need for treatment with drugs that are known CYP3A4 or CYP1A2 inducers (ie, carbamazepine, dexamethasone, felbamate, omeprazole, phenobarbital, phenytoin, amobarbital, nevirapine, primidone, rifabutin, rifampin, and St. John's wort).

No myocardial infarction, severe/unstable angina, coronary/peripheral artery bypass graft, symptomatic congestive heart failure or any unstable arrhythmia, cerebrovascular accident or transient ischemic attack, within the 12 months prior to study drug administration.

26. No serious uncontrolled medical disorder or active infection that would impair their ability to receive study treatment;
27. No history of a malignancy (other than glioma) except those treated with curative intent for skin cancer (other than melanoma) or in situ breast or cervical cancer or those treated with curative intent for any other cancer with no evidence of disease for 5 years;
