Positive results in preclinical and clinical studies in adults and infants with Prader-Willi syndrome lead investigators to set up a new study in children with Prader-Willi syndrome. The objective of this study is to document effects of oxytocin intranasal administrations on behavioural troubles in children with Prader-Willi syndrome aged from 3 to 12 years.
Two groups of patients will be constituted according to their age; "Group 1" children aged from 3 to 6 years (n = 20) and "Group 2" children aged from 7 to 12 years (n = 20). Within each group, subjects will be randomized to receive either oxytocin or placebo for 12 consecutive weeks. A second period of 12 consecutive oxytocin treatment weeks will then be performed for all patients, followed by a 4-week observation period to document effects after discontinuation of treatment.

The packaging, presentation and labelling of the bottles used during the blind phase will guarantee the blindness to the healthcare team and the patient.
The allocation of the treatment arms to each treatment number will be carried out according to the randomization table established beforehand.
Until the end of the study, neither the investigating physician nor the patient will know the group to which the patient has been randomly assigned.

| Placebo | Drug | Placebo should be used as a spray, similar to that of the oxytocin. The dosage administered will be 1 spray in each nostril per day for the first 12 weeks in 3 to 6 years old patients. The dosage administered will be 2 sprays in each nostril per day for the first 12 weeks, in 7 to 12 years old patients. |
|
|
| Oxytocin | Drug | Each patient will receive oxytocin in open label (Syntocinon® not reconditioned) from week 13 to week 24 according to the same dosages. |

It is variation between day 0 and week 12 of the total score obtained from the social skills assessment questionnaire for children aged from 3 to 6 years and the Social Responsiveness Scale questionnaire for children aged from 7 to 12 years. |
| Week 12 |
| Evaluation of auto- and hetero-aggressive after 12 weeks of oxytocin/placebo treatment. | It is variation between day 0 and week 12 of the total score obtained from the self-aggression assessment questionnaire. | Week 12 |
| Evaluation of psychopathology after 12 weeks of oxytocin/placebo treatment. | It is the variation of the following sub-scores obtained from the Child Behaviour Check List questionnaire (only the following 3 subscales) between day 0 and week 12. | Week 12 |
| Evaluation of global clinical status after 12 weeks of oxytocin/placebo treatment. | It is improvement of the patient's overall clinical condition after 12 weeks of treatment with oxytocin/placebo. It's assessed by the Clinical Global Impression Scale's score. This scale of improvement of Clinical Global Impression is a 7-point ordinal qualitative scale of "very greatly improved" rated + 3 to "very strongly aggravated" rated -3. The result is expressed in total score which varies from -3 to +3. | Weeks 12 |
| Evaluation of acyl and desacyl ghrelin plasma levels after 12 weeks of oxytocin/placebo treatment. | It is evolution of circulating levels of acylated and deacylated ghrelin will be the variations of these rates and the variation of the relationships between day 0 and week 12. | Week 12 |
