Primary	Change From Baseline at Week 24 on the Vineland Adaptive Behavior Scales (Vineland-II) Two-domain Composite (2DC) Score.	Week 24	Vineland™-II Adaptive Behavior Scales 2-Domain Composite (2DC) Score is defined as mean of the Communication domain standard score \& Socialization domain standard score. If any of the 2 individual domain standard scores is missing 2DC score is not computed. Vineland™-II is an instrument that measures communication, daily living skills, socialization, motor skills and maladaptive behavior of individuals with developmental disabilities. Survey Interview Form will be administered to a subject's reliable study partner in this study, during which the rater or clinician will ask to the study partner open ended questions relating to the subject's activities and behavior. Standardized scores on the Adaptive behavior composite range from 20-160 with higher scores indicating better functioning.
Secondary	Change From Baseline at Week 12 on the Vineland-II 2DC Score	Week 12	Vineland™-II Adaptive Behavior Scales 2-Domain Composite (2DC) Score is defined as mean of the Communication domain standard score \& Socialization domain standard score. If any of the 2 individual domain standard scores is missing 2DC score is not computed. Vineland™-II is an instrument that measures communication, daily living skills, socialization, motor skills and maladaptive behavior of individuals with developmental disabilities. Survey Interview Form will be administered to a subject's reliable study partner in this study, during which the rater or clinician will ask to the study partner open ended questions relating to the subject's activities and behavior. Standardized scores on the Adaptive behavior composite range from 20-160 with higher scores indicating better functioning.
Secondary	Change From Baseline at Weeks 12 and 24 in the Pediatric Quality of Life (PedsQL) Inventory Generic Core Scales, Version 4.0, on Summary and Total Scores	Weeks 12 and 24	The Pediatric Quality of Life Inventory PedsQL™4.0 Generic Core Scale assessment consists of a 23 item questionnaire encompassing 4 core scale domains: Physical Functioning (8 items); Emotional Functioning (5 items); Social Functioning (5 items); and School Functioning (5 items). Items are scored on a 5 point Likert-type response scale (0=never a problem; 1=almost never a problem; 2=sometimes a problem; 3=often a problem; and 4=almost always a problem). Once scored, items will be reverse scored and linearly transformed to a 0-100 scale (0=100, 1=75, 2=50, 3=25, 4=0), so that higher scores indicate better health-related quality of life.
Secondary	Change From Baseline at Weeks 12 and 24 in the Vineland-II Adaptive Behavior Composite Standard Score	Weeks 12 and 24	The Vineland-II is an instrument that measures communication, daily living skills, socialization, motor skills (only in children up to 6 years) and maladaptive (not assessed in this study) behavior of individuals with developmental disabilities. The Survey Interview Form (i.e., semi -structured interview) will be administered to a subject's reliable study partner in this study, during which the rater or clinician will ask to the study partner open ended questions relating to the subject's activities and behavior. Domain scores will be obtained for the individual domains of Socialization, Communication, Daily Living Skills, and motor skills (up to 6 years only) and used to calculate the Vineland-II Adaptive Behavior Composite score. Standardized scores on the Adaptive behavior composite range from 20-160 with higher scores indicating better functioning. Only descriptive statistics presented instead of the planned estimated due to the early discontinuation of the study due to futility.
Secondary	Change From Baseline at Week 12 and 24 on the Vineland-II Socialization Domain Standard Score	Baseline, Weeks 12 and 24	The Vineland-II is an instrument that measures communication, daily living skills, socialization, motor skills (only in children up to 6 years) and maladaptive (not assessed in this study) behavior of individuals with developmental disabilities. The Survey Interview Form (i.e., semi -structured interview) will be administered to a subject's reliable study partner in this study, during which the rater or clinician will ask to the study partner open ended questions relating to the subject's activities and behavior. Domain scores will be obtained for the individual domains of Socialization, Communication, Daily Living Skills, and motor skills (up to 6 years only) and used to calculate the Vineland-II Adaptive Behavior Composite score. Standardized scores on the Adaptive behavior composite range from 20-160 with higher scores indicating better functioning. Only descriptive statistics presented instead of the planned estimand due to the early discontinuation of the study due to futility.
Secondary	Change From Baseline at Weeks 12 and 24 on the Vineland-II Communication Domain Standard Score	Weeks 12 and 24	The Vineland-II is an instrument that measures communication, daily living skills, socialization, motor skills (only in children up to 6 years) and maladaptive (not assessed in this study) behavior of individuals with developmental disabilities. The Survey Interview Form (i.e., semi -structured interview) will be administered to a subject's reliable study partner in this study, during which the rater or clinician will ask to the study partner open ended questions relating to the subject's activities and behavior. Domain scores will be obtained for the individual domains of Socialization, Communication, Daily Living Skills, and motor skills (up to 6 years only) and used to calculate the Vineland-II Adaptive Behavior Composite score.

Secondary	Change From Baseline in Severity of Clinical Impressions as Measured by Clinical Global Impression-Severity (CGI-S)	Weeks 12 and 24	The CGI-S reflects the rater's impression of the subject's current autism severity on a 7-point scale ranging from no symptoms (1) to very severe symptoms (7). Changes in CGI-S score were calculated as increase or decrease in absolute CGI-S scores between Baseline and Weeks 12 and 24. Percentage of participants reported for each change in score from baseline.
Secondary	Improvements in Clinical Impressions, as Measured by Clinical Global Impression-Improvement (CGI-I)	Weeks 12 and 24	This is a 7-point Likert scale that assesses improvement of the patient's condition. Scores range from the worst score of 7 (Very much worse) to the best score of 1 (Very much improved). Lower scores are better on this scale, and indicate greater improvement. Percentage of participants reported for each score.
Secondary	Change From Baseline at Weeks 12 and 24 in the Hamilton Anxiety Rating Scale (HAM-A) Total and Domain Scores	Weeks 12 and 24	The HAM-A is a 14-item, rater administered interview, assessing the severity of anxiety symptoms during the past 7 days. Seven items assess psychic anxiety and seven assess somatic anxiety. Each item utilizes a 5-point symptom severity response scale, ranging from none (0) to very severe (4). A total score is calculated that ranges from 0 to 56; higher scores are indicative of more severe anxiety.
Secondary	Proportion of Subjects With a >=6-point Improvement in Vineland-II 2DC Score	Weeks 12 and 24	The Vineland-II is an instrument that measures communication, daily living skills, socialization, motor skills (only in children up to 6 years) and maladaptive (not assessed in this study) behavior of individuals with developmental disabilities.
