The goal of this double-blind, placebo-controlled study is to examine the effect of intranasally administered insulin on the development and behaviour of children with Phelan-McDermid syndrome. This study is a collaboration between the Special Education department of the University of Groningen and the Paediatric Medicine, Clinical Genetics, and Epidemiology departments and the Hospital Pharmacy of the University Medical Centre Groningen. It is funded by ZonMW – The Netherlands Organisation for Health Research and Development (Priority Medicines for Children, project number 40-41500-98-11038).
Clinical study carried out May 2012 through May 2015
Previous research has demonstrated that the activity of the SHANK3 protein in the brain is either directly or indirectly influenced by insulin. It is therefore possible that administration of additional insulin via a different mechanism can compensate for a shortage of SHANK3. A pilot study in Germany on six children with Phelan-McDermid syndrome in which insulin was administered via nose spray (intranasally) suggested that intranasal insulin can improve the functioning of children with Phelan-McDermid syndrome (1). However, participants in this study varied considerably in age and development, reducing the reliability of the results. Moreover, the long-term effects of intranasal insulin use remain unknown. For these reasons, it is critical to carry out well-designed studies, under well-controlled conditions, before recommending intranasal insulin treatment for children with Phelan-McDermid syndrome.
