Primary Outcome Measures
NameTimeMethod
Childhood Autism Rating Scale, Second Edition (CARS2) Total Raw ScoreChange from baseline to Week 26

The CARS2 total raw score range from 15 to 60. This scale is a behaviour rating scale intended to diagnose autism. A total score of 15 indicates that an individual behaviour is within normal limits, whereas a value of 60 indicates that the individual's behaviour is severly abnormal.

In term of change from baseline, the greater the mean value decreases, the better it is.

Secondary Outcome Measures
NameTimeMethod
Clinical Global Impression - Global Improvement (CGI-I) ScoreAt Week 26

Scale which assesses the severity of the illness and the global improvement of the patient under study treatment.

It ranges from 1 (normal) through to 7 (amongst the most severely ill patients).

Number of Patients With Abnormalities in 12-leads Electrocardiogram (ECG) ParametersWeek 26

Number of patients with clinically significant ECG abnormalities

The 12-lead electrocardiogram (ECG) is a medical test that is recorded using leads, or nodes, attached to the body. Electrocardiograms (ECGs), capture the electrical activity of the heart and transfer it to graphed paper where abnormalities are reported and interpretated by the cardiologist.

Number of Participants Experiencing at Least 1 Treatment Emergent Adverse Event (TEAE)through week 52
Vineland Adaptative Behaviour Scale II (VABS II)Change from baseline to Week 26

Scale designated to measure adaptative behaviour The scale for behaviour ranges from 1 to 67. The more the score decreases, the better it is.

Acceptability and Palatability Questionnaires - Only Descriptive AnalysesWeek 26

Acceptability and palatability criterion Based on your child's reactions (indirect rating), do you think that he/she found the administration method to be

Social Responsiveness Scale, Second Edition (SRS-2) Total Raw ScoreChange from baseline to Week 26

The SRS-2 total raw score serves as an index of severity of social deficits in the autism spectrum.

In terms of change from baseline, the greater the mean value decreases, the better it is.

Paediatric Quality of Life Inventory (PedsQL) QuestionnaireChange from baseline to week 26
