Date de début de l'étude : 31 août 2017

Inclusion Criteria: 1. Signed written informed consent by parent(s)/legal guardians of the pediatric patient in compliance with the local laws and regulations. In addition signed children's assent form according to local requirements. 2. Male or female in- or out-patient from birth to \< 18 years at the time of randomization. 3. Patient weight at least 3.3 kg. 4. Naïve or non-naïve patient with histologically, and/or cytologically (or imaging in the case of brain tumors) confirmed malignant disease. 5.

For patient aged ≥ 10 years: Eastern Cooperative Oncology Group Performance Status (ECOG PS) ≤ 2. 7. For patient aged 2 years with known mild to moderate hepatic impairment: in the Investigator's opinion the impairment does not jeopardize patient's safety during the study. 8. For patient aged 2 years with known mild to moderate renal impairment: in the Investigator's opinion the impairment should not jeopardize patient's safety during the study. 9. For patient with known history or predisposition to cardiac abnormalities: in the Investigator's opinion the history/predisposition should not jeopardize patient's safety during the study. 10. If the patient is female, she shall: a) not have attained menarche yet or b) have attained menarche and have a negative pregnancy test at the screening visit and at Day 1. 11.

The patient and/or parents/caregivers are expected by the Investigator to be non-compliant with the study procedures. 2. Patient has received or is scheduled to receive total body irradiation, total nodal irradiation, upper abdomen radiotherapy, half or upper body irradiation, radiotherapy of the cranium, craniospinal regions, head and neck, lower thorax region or the pelvis within 1 week prior to study entry (Day 1) or within 120 h after start of chemotherapy administration on Day 1. 3. Known history of allergy to any component or other contraindications to any Neurokinin-1 (NK1) or 5-hydroxytryptamine 3 (5-HT3) receptor antagonists. 4. Active infection. 5.

Patient suffering from ongoing vomiting from any organic etiology (including patients with history of gastric outlet obstruction or intestinal obstruction due to adhesions or volvulus, patients with a symptomatic central nervous system(CNS) tumor causing nausea and/or vomiting) or patient with hydrocephalus. 7. Patient who experienced any vomiting, retching, or nausea within 24 h prior to the administration of the study drug 8. Patient who received any drug with potential anti-emetic effect within 24 h prior to the start of reference chemotherapy, including but not limited to: NK1- receptor antagonists (e.g., aprepitant or any other new drug of this class); 5-HT3 receptor antagonists (e.g., ondansetron, granisetron, dolasetron, tropisetron, ramosetron); Benzamides (e.g., metoclopramide, alizapride); Phenothiazines (e.g., prochlorperazine, promethazine, perphenazine, fluphenazine, chlorpromazine, thiethylperazine); Benzodiazepines initiated 48 h prior to study drug administration or expected to be received within 120 h following initiation of chemotherapy, except for single doses of midazolam, temazepam or triazolam; Butyrophenones (e.g., droperidol, haloperidol); Anticholinergics (e.g., scopolamine, with the exception of inhaled anticholinergics for respiratory disorders e.g., ipratropium bromide); Antihistamines (e.g., diphenhydramine, cyclizine, hydroxyzine, chlorpheniramine, dimenhydrinate, meclizine); Domperidone; Mirtazapine; Olanzapine; Prescribed cannabinoids (e.g., tetrahydrocannabinol, nabilone); Over the Counter (OTC) antiemetics, OTC cold or OTC allergy medications; Herbal preparations containing ephedra or ginger. 9. Patient who received palonosetron within 1 week prior to administration of study drug. 10. Patient who has been started on systemic corticosteroid therapy within 72 h prior to study drug administration or is planned to receive a corticosteroid as part of the chemotherapy regimen 11. Patient aged \< 6 years who received any investigational drug (defined as a medication with no marketing authorization granted for any age class and any indication) within 90 days prior to Day 1, or patient aged 6 years who received any investigational drug within 30 days prior to Day 1 or is expected to receive investigational drugs prior to study completion. 12. Intake of alcohol, food or beverages (e.g., grapefruit, cranberry, pomegranate and aloe vera juices, German chamomile) known to interfere with either CYP3A4 or CYP2D6 metabolic enzymes within 1 week prior to Day 1 and during the overall study period. 13. Use of any drugs or substances known to be strong or moderate inhibitors of CYP3A4 and CYP2D6 enzymes within 1 week prior to Day 1 or planned to be used during the overall study period. 14. Use of any drugs or substances known to be CYP3A4 substrates with narrow therapeutic range within 1 week prior to Day 1, or planned to be used during the overall study period. 15. Use of any drugs or substances known to be inducers of CYP3A4 enzymes within 4 weeks prior to Day 1 or planned to be used during the overall study period. 16. Lactating female patient. 17. Patient with clinically relevant abnormal laboratory values that in the Investigator's opinion jeopardize the patient's safety during the study. 18. Patient aged \< 2 years with known hepatic impairment (any grade), or patient aged 2 years with known severe hepatic impairment. 19.
