The data for pharmacologic treatment of repetitive behaviours in this disorder has also become difficult to interpret given that the last two large multisite trials of selective serotonin re-uptake inhibitors (SSRIs) in autism are reported to be negative for the treatment of repetitive behaviours. Only the associated symptom of irritability has 2 drugs with Food and Drug Administration (FDA) indications, whereas no systematic data exists on the pharmacologic treatment of anxiety in ASD, and response rates to stimulants for hyperactivity are lower than what is seen in Attention Deficit Hyperactivity Disorder (ADHD). In addition, there are no biological markers of treatment response identified in this population at this point. This study will examine the potential efficacy and safety of tideglusib for core and associated symptom domains of autism, and will explore biological markers of safety and treatment response. As there is no juvenile toxicity published in the animal model, we will limit the age range to 12 years of age and older.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD'], 'maximumAge': '17 Years', 'minimumAge': '12 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n1. Outpatients 12-17 years of age inclusive with a mental age equivalent ≥ 18 months at Screening.\n2. Weigh a minimum of 30 kg (the 3rd percentile for 12 years of age)\n3. Meet Diagnostic and Statistical Manual of Mental Disorders. Diagnostic and Statistical Manual (DSM-5) criteria will be established by a clinician with expertise with individuals with ASD.\n4. Have a Clinician's Global Impression-Severity (CGI-S) score ≥ 4 (moderately ill) at Screening.\n5. If already receiving stable concomitant medications affecting behaviour, have stable regimens with no changes during the preceding 1 month prior to Screening (with the exception of fluoxetine, where a period of 6 weeks is needed), and will not electively initiate new or modify ongoing medications for the duration of the study\n6. If already receiving stable non-pharmacological educational and behavioural interventions, have continuous participation during the preceding 3 months prior to Screening, and not electively initiate new or modify ongoing interventions for the duration of the study\n7. Have normal physical examination and laboratory test results at Screening. If abnormal, the finding(s) must be deemed clinically insignificant by the Investigator.\n8. Ability to obtain written informed consent from the participant, if developmentally appropriate. If a participant does not have the capacity to consent, ability to obtain assent (if developmentally appropriate), as well as written informed consent from their parent(s)/legal guardian.\n\nExclusion Criteria:\n\n1. Patients with a primary psychiatric diagnosis other than ASD\n2. Pregnant female patients; sexually active female patients on inadequate birth control.\n3. Patients with known phosphatase and tensin homolog (PTEN) mutations as they are unlikely to respond to this medication\n4. Patients with a serious medical condition that, based on Investigator judgment, might interfere with the conduct of the study, confound interpretation of the study results, or endanger their own well-being. 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 pediatric diseases in these areas that are stable (e.g. mild asthma, constipation, etc.).\n5. Patients with unstable epilepsy (i.e. seizures occurring within the last 6 months), or patients with epilepsy who are not on stable doses of antiepileptic medications (i.e. dose changes within the last 3 months).\n6. Patients with hypersensitivity to tideglusib or any components of its formulation.\n7. Patients unable to tolerate venipuncture procedures for blood sampling.\n8. Patients actively enrolled in another intervention study.\n9. Patients who have elevated liver enzymes ≥ 3 times the normal amount before the study begins.\n10. Patients who have serum creatinine of \\>150 μmol/L and creatinine clearance ≤60ml/m (according to Cockcroft-Gault formula) at Screening.\n11. Patients taking strong CYP3A4 inhibitors (e.g. clarithromycin, telithromycin, ketoconazole, itraconazole, posaconazole, nefazodone, indinavir, ritonavir)\n12. Inability to speak and understand English sufficiently enough to allow for the completion of all study assessments (parent; patient, if verbal)."}, 'identificationModule': {'nctId': 'NCT02586935', 'acronym': 'TIDE', 'briefTitle': 'Tideglusib vs. Placebo in the Treatment of Adolescents With Autism Spectrum Disorders', 'organization': {'class': 'OTHER', 'fullName': 'Holland Bloorview Kids Rehabilitation Hospital'}, 'officialTitle': 'A Randomized Placebo-controlled Trial of Tideglusib vs. Placebo in the Treatment of Adolescents With Autism Spectrum Disorders (ASD)', 'orgStudyIdInfo': {'id': 'TIDE-06-2015'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'ACTIVE_COMPARATOR', 'label': 'Tideglusib', 'interventionNames': ['Drug: Tideglusib']}, {'type': 'PLACEBO_COMPARATOR', 'label': 'Placebo', 'interventionNames': ['Other: Placebo']}], 'interventions': [{'name': 'Tideglusib', 'type': 'DRUG', 'description': 'Administered orally after dispersion in approximately 100 ml of water at dose levels of 400 to 1000 mg', 'armGroupLabels': ['Tideglusib']}, {'name': 'Placebo', 'type': 'OTHER', 'description': 'Administered orally after dispersion in approximately 100 ml of water', 'armGroupLabels': ['Placebo']}]}, 'contactsLocationsModule': {'locations': [{'zip': 'L8S 4K1', 'city': 'Hamilton', 'state': 'Ontario', 'country': 'Canada', 'facility': 'McMaster University, Offord Centre for Child Studies', 'geoPoint': {'lat': 43.25011, 'lon': -79.84963}}, {'zip': 'N6A 5W9', 'city': 'London', 'state': 'Ontario', 'country': 'Canada', 'facility': 'University of Western Ontario, Lawson Health Research Institute', 'geoPoint': {'lat': 42.98339, 'lon': -81.23304}}, {'zip': 'M4G 1R8', 'city': 'Toronto', 'state': 'Ontario', 'country': 'Canada', 'facility': 'Holland Bloorview Kids Rehabilitation Hospital', 'geoPoint': {'lat': 43.70643, 'lon': -79.39864}}], 'overallOfficials': [{'name': 'Evdokia Anagnostou, M.D.', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Holland Bloorview Kids Rehabilitation Hospital'}, {'name': 'Terry Bennett, M.D.', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'MacMaster University, Offord Centre for Child Studies'}, {'name': 'Robert Nicolson, M.D.', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'University of Western Ontario, Lawson Health Research Institute'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Holland Bloorview Kids Rehabilitation Hospital', 'class': 'OTHER'}, 'collaborators': [{'name': 'McMaster University', 'class': 'OTHER'}, {'name': 'Western University, Canada', 'class': 'OTHER'}, {'name': 'Unity Health Toronto', 'class': 'OTHER'}, {'name': 'University of Toronto', 'class': 'OTHER'}], 'responsibleParty': {'type': 'SPONSOR'}}}}
