7. \- For Phase I exclusively, patients must have radiographically documented evaluable or measurable progressive disease by CT-scan, IRM or PET-scan 18F-FDG (measure of SUL and extension).

\- For Phase II exclusively, patients must have radiographically documented measurable and evaluable progressive disease. At least one site of disease might be measurable as follows: i. CT-scan, physical exam ≥10 mm ii. Chest X-ray ≥20 mm iii. Lymph node short axis ≥10 mm iv. Bone and marrow invasion on PET-scan FDG (measure of SUL and extension) All radiology studies must be performed between 7 and 28 days before the first dose of study treatment (C1D1).
8. Adequate cardiac function with a shortening fraction ≥29% and left ventricular ejection fraction ≥50% at baseline (between 7 and 28 days before the first dose of study treatment (C1D1)), as determined by echocardiography.
9. Adequate organ function within 21 days prior to first dose of study treatment:

16. Alanine aminotransferase (ALT)/Serum glutamic pyruvic transaminase (SGPT) ≤2.5 × ULN and Aspartate aminotransferase (AST)/Serum glutamic oxaloacetic transaminase (SGOT) ≤2.5 × ULN, except in patients with documented tumor involvement of the liver who must have ALT/SGPT and AST/SGOT ≤5 x ULN.
17. Females of childbearing potential (WOCBP) must have a negative serum pregnancy test within 72 hours prior to first dose of study treatment.
18. Sexually active WOCBP must agree to use a highly effective contraception method during the study treatment and for at least 6 months after the last study treatment administration.

19. Written informed consent from parents/legal representative, patient, and age-appropriate assent before any study-specific screening procedures are conducted, according to local, regional or national guidelines.
20. Patients able to comply with study procedures, scheduled follow-up and with management of toxicity.
21. Patient affiliated to a social security regimen or beneficiary of the same according to local requirement

Exclusion Criteria:

1. Absence of tumor target(s): for Phase I: absence of visible and evaluable target; for Phase II: absence of evaluable target.
2. Prior administration of mTOR inhibitors.
3. Impairment of gastrointestinal (GI) function or GI disease that may significantly alter drug absorption of oral drugs (e.g., chronic inflammatory bowel disease, ulcerative diseases, uncontrolled nausea, vomiting, diarrhea, or malabsorption syndrome).
4. Clinically significant uncontrolled heart disease (including history of any cardiac arrhythmias, e.g., ventricular, supraventricular, nodal arrhythmias, or conduction abnormality), congestive heart failure \> class II NYHA with 12 months of screening, unstable angina or new-onset angina.
5. Prior medical history of uncontrolled hypertension defined as follow:

1. Patients aged ≤ 17 years: greater than 95th percentile systolic and diastolic blood pressure based on age and weight which is not controlled by one anti-hypertensive medication.
   2. Patients aged \> 17 years: systolic blood pressure \> 150mmHg and/or diastolic \> 90 mmHg that is not controlled by one anti-hypertensive medication.
6. Thrombotic or embolic events within the past 6 months.
7. Evidence of interstitial lung disease.
8. Non-controlled hyperlipidemia: At fasting: Serum cholesterol \>3 g/L or 7.75mmol/L and Triglycerides \>2.5 ULN).
9. Constitutional abnormality of coagulation and/or hemostasis.

14. Systemic anticancer therapy within 21 days of the first study dose or 5 times its half-life, whichever is less.
15. Previous myeloablative therapy with autologous hematopoietic stem cell rescue within 8 weeks of the first dose of study treatment.
