Placebo Comparator: DB Placebo Nasal Spray
Placebo treatment during weeks 0-24 double blind phase
|
Drug: Double blind phase Placebo Nasal Spray
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 Name: 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
|
Drug: double Blind Oxytocin Nasal Spray
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.

- Change in Aberrant Behavior Checklist-Social Withdrawal Subscale ABC-SW, a Measure of Reciprocal Social Behavior [ Time Frame: Double-blind phase: baseline, weeks 4, 8, 12, 16, 20, 24 ]The primary outcome is Change in Aberrant Behavior Checklist-Social Withdrawal subscale- a measure ofreciprocal social behaviors. ABC-SW is a modification of the ABC-Lethargy subscale. The ABC-SW 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 higher level of social withdrawal.
- ABC-SW (Aberrant Behavior Checklist-Social Withdrawal) Subscale - Reciprocal Social Behavior [ Time Frame: Least mean squares for Open Label: weeks 24 -48 ]The ABC-SW 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.
- 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. NOTE THIS MEASURE WAS ELIMINATED FROM FINAL SAP'S
- Change in Social Reciprocity 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.
- Social Reciprocity Scale-2 (SRS-2) Social Motivation Subscale Score [ Time Frame: Open Label: weeks 24, 48 ]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.
- 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.
- Change in Vineland II Adaptive Behavior Scales (VABS-II) Composite Score [ Time Frame: Double-blind phase: baseline, week 24 ]Functional skills including communication will be assessed using the VABS-II Adaptive Behavior Composite Score. Uses standard score with a mean of 100 and SD of 15 with a range of 20-160. Higher score is better. Higher value in change indicates more improvement.
- Change in Vineland II Adaptive Behavior Scales (VABS-II) Socialization Domain Score [ Time Frame: Double-blind phase: baseline, week 24; Open Label: week 48 ]Functional skills will be assessed using the VABS-II Socialization Domain Score. Uses standard score with a mean of 100 and SD of 15 with a range of 20-160. Higher score is better. Higher value in change indicates more improvement.
- Change in Vineland II Adaptive Behavior Scales (VABS-II) Daily Living Domain Score [ Time Frame: Double-blind phase: baseline, week 24; Open Label: week 48 ]Functional skills will be assessed using the VABS-II Daily Living Domain Score. Uses standard score with a mean of 100 and SD of 15 with a range of 20-160. Higher score is better. Higher value in change indicates more improvement.
- Change in Vineland II Adaptive Behavior Scales (VABS-II) Communication Domain Score [ Time Frame: Double-blind phase: baseline, week 24; Open Label: week 48 ]Functional skills will be assessed using the VABS-II Communication Domain Score. Uses standard score with a mean of 100 and SD of 15 with a range of 20-160. Higher score is better. Higher value in change indicates more improvement.
- Change in Caregiver Strain Questionnaire (CSQ) Subjective Internalizing Subscale Score [ Time Frame: Double-blind phase: baseline, week 24 ]Caregiver questionnaire that assesses the impact of caring for the proband on caregiver and family. CSQ subscale scores are ranged from 1 to 5. with each item of the subscale having the same range, the sum of the items within the subscale are summed, and the mean score is determined (I.e. a single # between 1 and 5) and reported. Higher scores indicate more caregiver strain. Lower value in change indicates more improvement.
- Caregiver Strain Questionnaire (CSQ) Subjective Internalizing Subscale Mean Score [ Time Frame: Open Label: weeks 24, 48 ]Caregiver questionnaire that assesses the impact of caring for the proband on caregiver and family. Each item on the subjective internalizing CSQ subscale is rated from 1 to 5. Then all items within the subscale are summed and the mean is determined based on the number of items in the subscale. Higher score indicates more caregiver strain. Lower value in change indicates more improvement.
- Change in Caregiver Strain Questionnaire (CSQ) Subjective Externalizing Subscale Score [ Time Frame: Double-blind phase: baseline, week 24; Open Label: week 48 ]Caregiver questionnaire that assesses the impact of caring for the proband on caregiver and family. CSQ subscale scores are ranged from 1 to 5. Higher score indicates more caregiver strain. Lower value in change indicates more improvement.
- Change in Caregiver Strain Questionnaire (CSQ) Objective Subscale Score [ Time Frame: Double-blind phase: baseline, week 24; Open Label: week 48 ]Caregiver questionnaire that assesses the impact of caring for the proband on caregiver and family. CSQ subscale scores are ranged from 1 to 5. Higher score indicates more caregiver strain. Lower value in change indicates more improvement. The analysis directions for the instrument that are used in these analyses are the mean of all the responses in the scale or subscale.
- Changes in Biologic Outcome Measures [ Time Frame: Double blind phase: change from Baseline to week 8, and week 24. Open label phase change from week 24 to week 36. ]Investigators will obtain blood, urine and vital signs from participants at regular intervals in order to assess the safety of oxytocin. In addition,the blood samples will also be used to assess oxytocin levels, OTXR differential methylation status and to assess mRNA expression. Investigators will obtain saliva at the same time points to perform salivary oxytocin levels.
- Change in Clinical Global Impressions -Improvement Score (CGI-I) [ Time Frame: Double blind phase: change from Baseline to week 12, and week 24. Open label phase change from week 24 to week 48 ]The Clinical Global Impressions - Improvement score and Severity score, which is routinely used in pharmacologic clinical trials, will capture the study physician's global impression of response. scores of 1 and 2 are considered as a percentage of total subjects in arm
- 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.
