Clinical Trial Summary

This study is an 8-week open-label trial testing oxytocin nasal spray (Syntocinon) as a treatment for social impairment in adolescents with autism spectrum disorders (ASD). We hypothesize that oxytocin nasal spray will be safe, tolerable, and effective in improving the core symptoms of autism spectrum disorders in adolescents ages 11-17.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in ASD Symptoms Social Responsiveness Scales 2 (SRS-2) Scales From Baseline to Week 8	Change in ASD symptoms as measured by change from baseline on the Social Responsiveness Scale 2 (SRS-2) scale.; The SRS-2 is a 65-item rating scale completed that is used to measure the severity of autism spectrum symptoms as they occur in natural settings. The SRS-2 School Age form is completed by a parent or guardian for patients ages 9-17 and the SRS-2 Adult Self-report is completed by patients ages 18-59. Total raw scores range from 0 to 195, with higher scores indicating increased symptom severity.	Week-8
Primary	Number of Participants With =30% Reduction in SRS Raw Score and CGI Improvement Scores of = 2 at Week 8	The SRS-2 is a 65-item rating scale completed that is used to measure the severity of autism spectrum symptoms as they occur in natural settings. The SRS-2 School Age form is completed by a parent or guardian for patients ages 9-17 and the SRS-2 Adult Self-report is completed by patients ages 18-59. Total raw scores range from 0 to 195, with higher scores indicating increased symptom severity. The Clinical Global Impression Improvement scale (CGI-ASD-I) is a clinician rated measure of ASD improvement. Improvement scores range from 1 (very much improved) to 7 (very much worse).	Week-8
