Inclusion Criteria

-Signed informed consent form by patients and/or patients’ parents/legal guardians and age appropriate assent form by the patients obtained before any study specific procedure
-Male or female patients from 6 months to ≤ 21 years old at the time of study enrollment
-Confirmation of diagnosis:
--Phase I: Patients must have histologic verification of a solid tumor or lymphoma malignancy at diagnosis, with measurable or evaluable disease, for which there is no standard curative anti-cancer treatment or treatment is no longer effective and must have received ≥ 1 prior line of therapy.
--Phase II: patients must have histologically verified tumor at initial diagnosis and radiologically or histologically confirmed status at inclusion as indicated in the following: neuroblastoma, osteosarcoma, rhabdomyosarcoma or Ewing sarcoma.
--Patients with solid tumors must have measurable disease (evaluable disease is acceptable for neuroblastoma and Ewing sarcoma). Tumor assessment will be done via computed tomography (CT), magnetic resonance imaging (MRI) or positron emission tomography-computed
tomography (PET-CT). Tumor lesions situated in a previously irradiated area, or in an area subjected to other loco-regional therapy, may be considered measurable if there has been demonstrated progression in the lesion. Bone scans (if clinically indicated) should be obtained within ≤ 4 weeks prior to the start of treatment.
-Performance level: Lansky ≥ 50% for patients ≤ 16 years of age and Karnofsky ≥ 50% for patients > 16 years of age.
-Adequate bone marrow, renal and liver function.
