D: Inclusion Criteria:

1. Signed Written Informed Consent

   1. Participants or their legal representative must have signed and dated an IRB/IEC approved written informed consent form in accordance with regulatory and institutional guidelines. This must be obtained before the performance of any protocol related procedures that are not part of normal participant care. Participants who do not have the capacity to consent will give developmentally appropriate assent.
   2. Participants must be willing and able to comply with scheduled visits, treatment schedule, and laboratory testing.
   3. The subject's parent/caregiver/LAR must be able to speak and understand the local language where the study is conducted sufficiently to understand the nature of the study and to allow for the completion of all study assessments. The same parent/caregiver/LAR must be capable of providing reliable information about the subject's condition, agree to oversee the administration of study drug, and accompany the subject to all clinic visits.
   4. Patient must be able to speak and understand the local language where the study is conducted sufficiently to understand the nature of the study and to allow for the completion of all study assessments.
2. Type of Participant and Target Disease Characteristics

   1. Diagnosis of an Autism Spectrum Disorder according to the DSM-5 criteria
   2. Complex language as defined in ADOS-2 to qualify for a Module 3 or 4.
   3. Current pharmacological treatment regimen affecting behaviour has been stable for at least 6 weeks prior to screening and is expected to be stable during the duration of the study
   4. Current psychotherapeutic/psychosocial interventions affecting behaviour stable for 3 months prior to screening and expected to be stable during the duration of the study (standard regular school breaks and/or annual teacher/classroom change do not qualify for intervention change).
   5. Subjects with a history of seizure disorder must currently be receiving stable treatment with anticonvulsant medication and must have been seizure free for 6 months prior to screening, or must be seizure free for 3 years prior to screening if not currently on a stable (\>3 months) dose of antiepileptics.

   2. Reside with the parent/carer who is interviewed for the Vineland.
   3. Negative pregnancy test for females of childbearing potential (subject has experienced onset of menses) within 24h prior to study treatment starts.
   4. Females of childbearing potential who are sexually active must agree to use a highly effective form of contraception (i.e., existing surgical sterilization, complete abstinence, or a combination of two effective forms of contraception, such as, for example, condoms plus hormonal treatment).
   5. Male participants with female partners of childbearing potential are eligible to participate if they agree to the following conditions:

      * Inform any and all partner(s) of their participation in a clinical drug study and the need to comply with contraception instructions as directed by the investigator.
      * Male participants are required to use a condom for study duration and until end of relevant systemic exposure defined as 7 months after the end of study treatment.
