Title: Trichuris Suis Ova in Autism Spectrum Disorders
Brief Summary: The purpose of this study is to determine whether Trichuris Suis Ova (TSO) is safe and effective in treating adults with autism spectrum disorder


Options:
A: Inclusion Criteria:

* Participants meet Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria for ASD and Tenth Revision of the International Classification of Diseases and Related Health Problems (ICD-10) criteria for Autism diagnosis
* SRS-2 (T-score) greater than or equal to (\>/=) 66
* CGI-S \>/=4 (moderately ill)
* Participants have an Intelligence Quotient (IQ) \>/=70 (Wechsler Abbreviated State of Intelligence)
* A body mass index (BMI) between 18 to 40 kilograms per square meter (kg/m\^2) inclusive
* Language, hearing and vision compatible with the study measurements as judged by the investigator
* Lives with (or has substantial periods of contact with) a caregiver who is willing and able to attend visits when required, oversee the participant's compliance with protocol-specified procedures and study medication dosing, and report on the participant's status via completion of study assessments. Any period of absence must be covered by another caregiver. Non-cohabitating caregiver(s) must spend sufficient time with the participant so that, in the opinion of the investigator, the caregiver(s) can reliably assess participant's mental status, activities and behavior.

Exclusion Criteria:

* Alcohol and/or substance abuse/dependence during the last 12 months
* A significant risk for suicidal behavior, in the opinion of the investigator
* Systolic blood pressure greater than (\>) 140 or less than (\<) 90 millimeters of mercury (mm Hg), and diastolic blood pressure \>90 or less than (\<) 50 mm Hg
* Resting pulse rate \>90 or \<40 beats per minute
* Use of prohibited medications or herbal remedies within 2 weeks prior to randomization, or 5 half-lives (whichever is longer)
* Initiation of a new major change in psychological intervention within 4 weeks prior to randomization. Minor changes in ongoing treatment are not considered significant
* Participation in an investigational drug or device study within 60 days prior to randomization
B: Inclusion Criteria:

1. Age 18-35, inclusive, at the time of consent
2. Outpatient
3. Meet criteria for the diagnosis of Autism Spectrum Disorder according to the DSM-IV-TR, and supported by the ADOS or ADI-R.
4. Have an IQ of 70 or greater
5. Participants who are taking other medications prior to enrollment must be on a stable dose of concomitant medication, including psychotropic, anticonvulsant, or sleep aid for at least 3 months prior to baseline ratings
6. Be judged reliable for medication compliance and agree to keep appointments for study contacts and tests as outlined in the protocol (both subjects and guardians)
7. Have a personal or family history of allergies.

Exclusion Criteria:

1. History of Bipolar disorder or Psychotic Disorders (e.g. schizophrenia or schizoaffective disorders).
2. Previous diagnosis of Rett's Disorder or Childhood Disintegrative Disorder
3. Uncontrolled seizure disorders (seizures within the past 6 months)
4. Pregnant or breast feeding at screening, or at any time during the study
5. Chronic medical illness that would interfere with or contraindicate participation in the study, or clinically significant abnormalities in baseline laboratory testing or physical exam.
6. Treatment in the last 12 weeks with cyclosporine, methotrexate, infliximab or immunomodulatory agents
7. Treatment in the last 2 weeks with antibiotics, antifungal or antiparasitic medications
8. Presence of any organic or systemic disease or need for a therapeutic intervention, which would confound the interpretation of results.
9. History of previous treatment with Trichuris Suis Ova (TSO).
C: Inclusion Criteria:

1. Male or female outpatients 18 to 60 years of age.
2. Meet Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision. The diagnosis will be confirmed with Autism Diagnostic Interview-Revised and Autism Diagnostic Observation Schedule .
3. Have a Clinician's Global Impression-Severity score ≥ 4 (moderately ill) at Screening and Baseline.
4. If already receiving stable nonpharmacologic educational, behavioral, and/or dietary interventions, have continuous participation during the preceding 3 months prior to Screening and will not electively initiate new or modify ongoing interventions for the duration of the study.
5. Have normal physical examination and laboratory test results at Screening. If abnormal, the finding(s) must be deemed clinically insignificant by the Investigators.
6. The patient must be able to speak and understand English sufficiently to understand the nature of the study and to allow for the completion of all study assessments.
7. Have a normal Intelligence Quotient (\>70) supported by the Wechsler Abbreviated Scales of Intelligence.

Exclusion Criteria:

1. Patients born prior to 35 weeks gestational age.
2. Patients with any primary psychiatric diagnosis other than autism at Screening: a history of attention deficit hyperactivity disorder, bipolar disorder, psychosis, posttraumatic stress disorder, schizophrenia, or major depressive disorder.
3. Patients with a medical history of neurological disease, including, but not limited to, epilepsy/seizure disorder (except simple febrile seizures), movement disorder, tuberous sclerosis, fragile X, and any other known genetic syndromes, or known abnormal magnetic resonance imaging/structural lesion of the brain.
4. Pregnant female patients.
5. Patients with a medical condition that might interfere with the conduct of the study, confound interpretation of the study results, or endanger their own well-being. Patients with evidence or history of malignancy or any significant hematological, endocrine, cardiovascular (including any rhythm disorder), respiratory, renal, hepatic, or gastrointestinal disease.
6. Patients taking psychoactive medication(s) (e.g., stimulants, antidepressants, antipsychotics, antiepileptics, anxiolytics, clonidine).
7. Patients who plan to initiate or change nonpharmacologic interventions during the course of the study.
8. Patients unable to tolerate venipuncture procedures for blood sampling.
9. Patients who, in the Investigator's opinion, might not be suitable for the study.
D: Inclusion Criteria:

1. Males and females, Aged between 3 and 12 years.
2. Autistic disorder - DSM-IV criteria.

4. Clinical judgment that medication treatment for autism is indicated.

Exclusion Criteria:

7. Systemic diseases such as cardiac, renal, thyroid diseases, uncontrolled seizure disorder (seizure disorder that is not controlled by anti-epileptic medication - a child who is seizure free for a period of 6 months on a stable dose of antiepileptic drug would be considered controlled), or diabetes mellitus.
8. Children with a known medical cause for autistic disorder.
9. Abnormal fasting blood glucose or history of diabetes.
10. Baseline body mass index (BMI) greater than the 90th percentile for age and gender (CDC growth charts, Kuczmarski et al, 2000) (because of risk of weight gain).
