? 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. A copy of the scores must be available for the source file and the eCRF.
6. Normal physical examination and laboratory test results at Screening (Visit 0) or any abnormal findings must be deemed not clinically significant by the Investigator and documented
7. Normal sitting pulse rate by vital sign assessment. Any deviation from normal must be judged not clinically significant by the Investigator. Please refer to Appendix V for Normal ranges
8. Normal sitting blood pressure (BP). Any deviation from normal must be judged not clinically significant by the Investigator.
9. Ability to tolerate venipuncture procedures for blood sampling
10.

Be able to speak and understand English sufficiently (or their native language if this can be accommodated by the site), as well as have a caregiver and parent/guardian/LAR who is able to speak and understand English sufficiently (or their native language if this can be accommodated by the site), to comprehend the nature of the study and to allow for the completion of all study assessments

10. Medical conditions that might interfere with the conduct of the study, confound interpretation of the study results, or endanger the patient’s well-being. 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
