Registry summary

Text and fields below are the sponsor's entries at ClinicalTrials.gov, shown as posted.

The Prader-Willi syndrome (PWS) includes severe neonatal hypotonia with impaired suckling leading to failure to thrive in the most severe cases, subsequently followed by an early onset of morbid obesity with hyperphagia and deficit of satiety, combined with other endocrine dysfunction probably due to hypothalamic dysfunction. The pathophysiological mechanism of the occurrence of the 2 main nutritional phases of PWS is unknown. Swaab reported a deficit in the oxytocin (OT)-producing neurons of the paraventricular nucleus in the brain of these patients. In addition of its well-known anorexigenic effect, OT is involved in establishing and maintaining social codes. Moreover in a PWS mouse model generated from a MAGEL2 KO gene a single OT injection at 5 hr of life prevent the early death observed in 50 % of the new born mice by recovering normal suckling. Interestingly this effect is no longer observed if OT injection takes place later. Our hypothesis is that early administration of OT in babies with PWS may improve suckling and possibly infant-mother interactions. In our recent study (manuscript in preparation), we have shown that a single intranasal administration of OT is well tolerated. This escalating dose study is designed to evaluate the tolerance of repeated intranasal administration of OT in 3 steps (4IU every other day, 4 IU daily, 4IU twice daily) in babies younger than 5 months with PWS.
