ADOS (Autism Diagnostic Observation Schedule) Modules 2 or 3 ? ADI-R (Autism Diagnostic Interview–Revised) ADOS completed within the 6 months before Screening and ADI-R completed within the 3 months before Screening are acceptable provided that the assessments were done by a qualified rater.

Such conditions include, but are not limited to, evidence or history of malignancy or any significant hematologic, endocrine, cardiovascular (including any rhythm disorder), respiratory, renal, hepatic, or gastrointestinal disease. If there is a history of such disease but the condition has been stable for more than 1 year and is judged by the Investigator not to interfere with the patient's participation in the study, the patient may be included, with the documented approval of the Study Physician 10.
