Inclusion Criteria

1.1) Signed Written Informed Consent

Participants or their legal representative (LAR) must have signed and dated an 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.

Participants must be willing and able to comply with scheduled visits, treatment schedule, and laboratory testing.

The participant’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.

Participants 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

Diagnosis of an Autism Spectrum Disorder according to the DSM-5 criteria

Complex language (i.e. fluent language abilities) as defined in ADOS-2 to qualify for a Module 3 or 4, which would exclude individuals with significant cognitive impairments.

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

Current psychotherapeutic/psychosocial interventions affecting behaviour stable for 3 months prior to screening and are 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).

Participants 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.

3) Age, Residential and Reproductive Status

Male or female participants 5 to 17 years of age at the time of providing consent, inclusive.

Reside with the parent/carer who is interviewed for the Vineland.

Negative pregnancy test for females of childbearing potential (subject has experienced onset of menses) within 24h prior to study treatment onset.

Females of childbearing potential who are sexually active must agree to use an accepted form of contraception (i.e., existing surgical sterilization, abstinence or or a combination of two effective forms of contraception, such as for example, condoms plus hormonal treatment).

Exclusion Criteria

1) Medical Conditions

Subjects with any condition that might interfere with the conduct of the study, confound interpretation of the study results, or endanger their own well-being. This includes, but is not limited to impairment of renal function, evidence or history of malignancy or any significant haematological, endocrine, respiratory, hepatic, cardiovascular or gastrointestinal disease, including any clinically significant abnormalities on ECG. In general, any co-morbid conditions that may interact with study procedures.

2) Prior/Concomitant Therapy

Subjects who are currently receiving treatment with racemic baclofen, vigabatrin, tiagabine, gabapentin, pregabalin or riluzole or other GABA-related medications. Only regular benzodiazepine use (PM, i.e. at night) will be allowed.

Subjects who are currently receiving pharmacologic treatment affecting behaviour (see concomitant medication section) need to have a stable dose during the 6 weeks prior to the screening visit and for the duration of the study.

Participating in programs including non-pharmacologic educational, behavioural, and/or dietary interventions affecting behaviour, participation in these programs must have been continuous during the 3 months prior to screening and participants or their parent/caregiver/LAR may not electively initiate new or modify ongoing interventions for the duration of the study. Typical school vacations are not considered modifications of stable programming.

Potential participants who have taken another investigational drug within the last 30 days.

3) Physical and Laboratory Test Findings

Patients with evidence of any significant hematological, endocrine, cardiovascular (including uncorrected symptomatic congenital heart disease), respiratory, renal, hepatic, or gastrointestinal disease, not including mild common paediatric diseases in these areas that are stable (e.g. mild asthma, constipation, etc.), as judged by the investigator.

4) Study-medication related

Subjects who are not able to take oral medications.

Subjects who have a history of hypersensitivity to racemic baclofen.

Subjects with rare hereditary problems of galactose intolerance, lactase deficiency or glucose-galactose malabsorption should not take this medicine.

Active peptic ulceration as Baclofen stimulates gastric acid secretion.

Porphyria.

5) Other Exclusion Criteria

Subjects who are currently engaged in illicit drug use or alcohol abuse, according to DSM-5 criteria.

Subjects who have previously participated in a clinical trial of Arbaclofen.
