About
This open, multicentric, randomized, controlled study is planned to evaluate the correlation between gene expression, spontaneous catch-up growth and therapeutic response to Saizen in SGA children.
Full description
This open, multicentric, randomized, controlled study was planned to identify genes activated by hGH in SGA children responders to treatment (making it possible in the near future to better identify SGA children likely to benefit from hGH treatment). Furthermore, the study would hopefully allow to verify which genes were responsible of spontaneous catch-up growth in children with diagnosis of SGA at birth but above the third percentile for height at the age of 24 months, and if these genes were the same activated by hGH during the treatment in participants responders. Sixty children born at term (i.e. after the 37th completed week of gestation) and with a diagnosis of SGA (defined as a length less than tenth percentile according to the Italian reference table published by Bertini and Fabris) were planned to be enrolled in the study. Forty participants (group A) were still less than third percentile for height (according to the Tanner reference table) at the age of 24 months, the remaining 20 (group B) being more than or equal to third percentile (thus showing a spontaneous catch-up growth). Group A was randomized to receive Saizen at the daily dose of 0.067 mg/kg (Group A1) or no treatment (Group A2) for two years. All participants were to undergo full clinical examination and blood chemistry at baseline visit and visit after 1,6,12,18 and 24 months for a period of two years. Gene expression analysis using the Clontech Atlas Human Array was performed in all participants at baseline and after one year in order to identify the possible correlation between catch-up growth (either spontaneous or drug-induced) and expression of some genes.
