• Life expectancy ≥ 12 weeks

• Adequate bone marrow function :

• Absolute neutrophil count ≥ 1000/mm3; and ≥ 500/mm3 in case of bone marrow disease

• Platelet count ≥ 100000/mm3 ; and ≥ 75000/mm3 in case of bone marrow disease (transfusion independent)

• Hemoglobin ≥ 8.5 g/dl (transfusion allowed)

• Adequate renal function

• Serum creatinine ≤ 1.5 X ULN for age

• If serum creatinine > 1.5 ULN, creatinine clearance (or radioisotope GFR) must be >70 ml/min/1.73 m²

• Adequate hepatic function :

• Total bilirubin ≤ 1.5 times upper limit of normal (ULN) for age, except if the patient is known to have Gilbert's syndrome

• ALT and AST ≤ 2.5 times ULN for age

• Negative pregnancy test in females with childbearing potential

• Fertile patients must use effective contraception

• Patient affiliated with a health insurance system. Applicable for French patients only Written informed consent of patient and/or parents/guardians

• PRIOR or CONCURRENT THERAPY :

• More than 3 weeks since prior radiation therapy to the site of any progressive lesion that will be identified as a target lesion to measure tumor response

• At least 3 weeks since prior myelosuppressive therapy (6 weeks for nitrosourea. 2 weeks for vincristine, vinblastine, vinorelbine or low dose cyclophosphamide)

• No concurrent enzyme-inducing anticonvulsants (EIAC), including phenytoin, phenobarbital or carbamazepine

• No concurrent administration of any of the following: rifampicin, voriconazole,itraconazole, ketoconazole, aprepitant, St John's Wort

• No prior irinotecan or temozolomide administration

• Prior vincristine administration allowed

• Concurrent palliative radiation therapy to sites allowed other than the main measurable target

Exclusion Criteria:

• Inclusion criteria failure

• Concomitant anti-cancer treatment

• Know hypersensitivity to any component of study drugs or ingredients

• Pregnancy or breast feeding

• Patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption
