Study of Oxytocin in Autism to Improve Reciprocal Social Behaviors (SOARS-B)

May 27, 2021 updated by: Linmarie Sikich

Phase II Study of Oxytocin in Autism to Improve Reciprocal Social Behaviors

The purpose of this research study is to learn about the effects of supplemental intranasal oxytocin as a treatment for improving social difficulties in children and adolescents with autism. This study will also provide additional information about the safety and tolerability of intranasal oxytocin. Investigators expect oxytocin will increase social motivation, improving daily living skills and quality of life.

Study Overview

Detailed Description

There is a tremendous unmet need for accessible treatments that address core symptoms of ASD and are safe for sustained use. The Study of Oxytocin in ASD to improve Reciprocal Social Behaviors or (SOARS-B) will test a very promising potential treatment-intranasal oxytocin-for ASD's fundamental social communication deficits in a large, group of verbal and nonverbal children. SOARS-B will also provide information about the regulation of DNA methylation and transcription of the oxytocin receptor gene (OXTR), as well as other genes relevant to oxytocin's CNS activity, as a function of time and in response to oxytocin treatment. These data will fill a key gap in our understanding of oxytocin's role in ASD and its ability to alter epigenetic modifications of the OXTR.

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Quadruple

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Placebo Comparator: DB Placebo Nasal Spray
Placebo treatment during weeks 0-24 double blind phase
This nasal spray will contain all of the ingredients that are in the active oxytocin spray in the same quantities, except oxytocin will NOT be added to the solution. It will be packaged using the same container system as the active oxytocin nasal spray. Each bottle's label will have its own unique nonsequential randomly assigned number and not a lot number to facilitate masking. Dose titration will occur using exactly the same criteria and procedures as for active study drug.
Other Names:
  • DB Placebo (PL)
Active Comparator: DB Oxytocin Nasal Spray
DB Oxytocin- quadruply masked treatment with intranasal oxytocin during weeks 0-24 of study during double blind phase of study
Each insufflation will deliver 8 IU or 24 IU of oxytocin. A maximum of 3 insufflations at a time will be required. Dosing will be flexible between 8 IU/day and 80 IU/day, typically in two divided doses delivered in the morning and in the afternoon. Doses will typically increase by 8 IU twice daily (BID) at week 2 and weeks 4 and 8 until achieving the target dose of 24 IU BID at week 8. Subsequently doses may be increased in 8 IU BID increments ONLY at each visit until a maximum dose of 40 IU BID is achieved.Each bottle's label will have its own unique nonsequential randomly assigned number and not a lot number to facilitate masking. During the open label phase after approximately March 2019 the study used only the 24 IU /0.10 ml formulation and the maximum dose was 72 IU per day.
Other Names:
  • DB Intranasal Oxytocin (OT)
Active Comparator: open label intranasal oxytocin
non masked treatment with intranasal oxytocin from weeks 24-48 in those participants who completed first 24 weeks of double blind treatment
All participants who completed the 24 week double blind phase were eligible to join a 24 week open label phase in which all participants received intranasal oxytocin
Other Names:
  • open label treatment

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Aberrant Behavior Checklist-Modified Social Withdrawal Subscale ABC-mSW, a Measure of Social Reciprocity
Time Frame: Least Mean Squares Double-blind phase: change from baseline to week 24
The primary outcome is Change in Aberrant Behavior Checklist-Modified Social Withdrawal subscale- a measure of reciprocal social behaviors. ABC-mSW is a modification of the ABC-Lethargy subscale. The ABC-mSW consists of the sum of questions 5,12,16, 20, 23, 26, 30, 37, 40, 42, 43, 55, and 58. In contrast to the ABC-Lethargy subscale it eliminates question 3 (listless, sluggish, inactive), question 32 (sits or stands in one position for a long time), and question 53 (inactive, never moves spontaneously). Thirteen individual items are scored 0-3, therefore the range is 0-39. Higher score indicates lower social reciprocity. Repeated measures were obtained at baseline, weeks 4, 8, 12, 16, 20, 24.
Least Mean Squares Double-blind phase: change from baseline to week 24
Change in Aberrant Behavior Checklist-Modified Social Withdrawal Subscale ABC-mSW, a Measure of Social Reciprocity
Time Frame: Least mean squares for Open Label: Change between weeks 24-48
The ABC-mSW is described above and involves 13 items reflecting lack of reciprocal interaction. Each item is scored from 0 (never shows behavior) to 3 (behavior is a major problem). The range is 0-39. Higher scores indicate worse reciprocal social functioning.
Least mean squares for Open Label: Change between weeks 24-48

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Sociability Factor (SF)
Time Frame: Double-blind phase: change in least means squares between week 0 & 24.
The Sociability Factor (SF) is a summed measure of the13 items of the ABC-SW and the 18 items of the Pervasive Development Disorders Behavior Inventory-Screening Version (PDDBI-SV).The PDDBI-SV assesses both adaptive social behaviors and social problems typical of ASD. The adaptive behaviors are reverse scored so that all the analyzed scores range from 0-performing in a neurotypical fashion to 3 typically performs in a way associated with ASD. the total # of items on this summed measure is 31 with a range from 0 to 93. More impaired social functioning indicated by higher scores. This measure was changed to a secondary outcome in the final statistical analysis plan.
Double-blind phase: change in least means squares between week 0 & 24.
Change in Social Responsiveness Scale-2 (SRS-2) Social Motivation Subscale Score
Time Frame: Double-blind phase: baseline, weeks 12, 24
The SRS-Social Motivation subscale was developed to provide a quantitative measure of social impairments typically observed in ASD in children 3-18 years. Reported as T-score with a range of 38-90 for both boys and girls. Higher score indicates more severe clinical condition. Lower value in change indicates more improvement.
Double-blind phase: baseline, weeks 12, 24
Change in Stanford Binet-5th Edition (SB-5) IQ Score
Time Frame: Double-blind phase: baseline to week 24
Cognitive skills will be assessed using the Stanford Binet-5th Edition (SB-5) (Roid). Acceptable IQ range is 47-153, with higher score being better. Higher change scores indicate more improvement.
Double-blind phase: baseline to week 24

Reading Mind in the Eyes Test is an Objective Measures of the Extent to Which Verbal Participants With Rudimentary Knowledge of Emotion Names Are Able to Correctly Identify the Emotion Shown in a Black and White Picture of the Eyes and Nose of an Actor.
Time Frame: Double blind phase: change from Baseline and week 24. Note: only those who demonstrated understanding of these concepts were included in sample.
This computerized task consists of a series of pictures of eyes in which the participant needs to determine which emotion the eyes are expressing from 4 emotions listed along with the picture. The outcome is the % of pictures with correct emotion identified. The range is 0 to 100%. The larger percent identified correctly indicates better ability to perceive emotions. An increase or positive change indicates better ability to identify emotions since baseline.
Double blind phase: change from Baseline and week 24. Note: only those who demonstrated understanding of these concepts were included in sample.
