Official title
An Open Label Trial of Growth Hormone in Children and Adolescents With Phelan-McDermid Syndrome Targeting Social Withdrawal
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Phelan McDermid syndrome (PMS) is a rare genetic form of autism spectrum disorder (ASD) due to deletions or mutations in the SHANK3 gene. This is a pilot open labeled trial of growth hormone therapy in children with PMS targeting social withdrawal and repetitive behavior. This research study will include children with PMS between 2-12 years of age who will receive growth hormone daily for 12 weeks, if found to be eligible. The aim of this study is to evaluate the effect of growth hormone on behavioral outcomes such as the aberrant behavior checklist social withdrawal subscale (ABC-SW) and repetitive behavior scale- revised (RBS-R). The effects of growth hormone on visual evoked potentials will also be assessed. Growth hormone increases insulin like growth factor 1 (IGF-1) levels and a previous trial of IGF-1 therapy in PMS children showed improvement in these behavioral scales. Growth hormone has been studied for decades with an excellent safety profile and fewer adverse effects compared to IGF-1 therapy in other conditions. Hence, this may be a viable therapeutic option. There is no treatment currently available for PMS and this trial is therefore extremely important.
