Registry summary

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

Extensive data has been accumulated to suggest that central release of oxytocin is important for social cognition and function, as well as likely involved in anxiety modulation and repetitive behaviors. The principal investigators of this study have previously documented: 1) an association between Autism Spectrum Disorder and a single nuclear polymorphism of the oxytocin receptor gene, 2) ability to measure oxytocin levels in the blood by enzyme immunoassay and 3) preliminary data to support safety and efficacy of intranasal oxytocin in the treatment of social deficits and repetitive behaviors in adults with autism. A medication treatment targeting the core deficits of Autism Spectrum Disorder in childhood is highly valuable because it could influence the developmental trajectory and make further psychosocial interventions possible. In this context, we propose a small dose finding study to confirm that the dose used in the adult study is not more than the maximum tolerated dose in youth. '

Interventions

Intranasal OxytocinDrug

Arms1

Experimental
Intanasal Oxytocin
A modified dose finding method will be used to determine safety among four dose levels for Intranasal Oxytocin. Half the dose (0.2 IU/kg /dose) is the minimum dose and two intermediate doses will also be evaluated (0.26 and 0.33 IU/kg / dose) Dose-finding escalations will be done in groups of three patients.Three patients will be studied at the first dose level. If none of these patients experience dose limiting toxicity, the dose will be escalated. If one experiences dose limiting toxicity, up to three more will be accrued at the same level. If none of these experience dose limiting toxicity, the dose will be escalated. If one or more of these experience dose-limiting toxicity, entry at that dose level will be stopped. Up to three more patients will be treated at the next lower dose. If zero out of these experience dose limiting toxicity, an additional three patients will be treated at that dose.

Primary outcomes2

Outcomes the sponsor listed as primary.

Maximum Tolerated Dose (MTD)
Time frame · 12 Weeks
Registry description
The hypothesis is that the maximum tolerated dose in a range of 0.2-0.4 IU/kg / dose will be 0.4 IU/kg / dose, as was the case in the adult study, given that oxytocin is not stored in body fat and does not depend on liver or renal clearance.
Number of Participants With Serious Adverse Events
Time frame · 24 Weeks
Registry description
This will be reported as the number of participants who experienced a serious advert event throughout the study.

Secondary outcomes(2)

Baseline Levels of Oxytocin in Relation to Either Safety or Treatment Response
Time frame · 12 Weeks
Registry description
Children and adolescents with lower plasma oxytocin levels at baseline will show treatment related changes in social cognition. Children and adolescents with higher oxytocin plasma levels will show diminished or less dramatic treatment responses and may have more difficulty tolerating the treatment.
Blood Levels of Oxytocin During the Trial in Relation to Safety or Treatment Response
Time frame · 12 Weeks
Registry description
Children and adolescents with minimal changes in plasma level of oxytocin after treatment will be less responsive to treatment. Children and adolescents with atypical patterns of increase in oxytocin may be more sensitive to dose-related tolerability.

Intranasal OxytocinOxytocin: Intranasal Oxytocin. Please note that the Adverse Events are not presented per dose level received, as this is not a dose-finding study, it is a modified maximum tolerated dose study. This means that a small number of participants were exposed to increasing dose levels to assess for Adverse Events. It is not meaningful to analyze adverse events by cohorts due to the extremely small sample size.	–	0 / 15	15 / 15
