Study Stopped
Well tolerated but failed to demonstrate significant activity. So it did not meet its primary endpoint or key secondary endpoints.
TSO in Pediatric Autistic Spectrum Disorders

Brief Summary
The primary objective of this study is to evaluate and compare the safety and efficacy of Trichuris suis ova (TSO) therapy (versus placebo) in pediatric patients with autism. Evaluation of the safety and tolerability of treatment with TSO in the target population across the dose range being tested is considered a primary objective, while the primary efficacy objective will be assessed via the change from baseline in the Aberrant Behavior Checklist (ABC) subscale scores. Dose response will be considered a primary objective as well. Secondary assessments of efficacy will be assessed via: • The change from baseline in the Clinical Global Impression scale (CGI-I)

Outcome Measures
Primary Outcomes (1)
Aberrant Behavior Checklist (ABC) subscale scores
The ABC consists of 58 questions and the five subscales as described above. Each question on the ABC is rated on a 4-point scale: 0 = 'not a problem,' 1 ='the behavior is a problem but slight in degree,' 2 = 'the problem is moderately serious,' and 3 = 'the problem is severe in degree.' The subscale score is the sum of the responses to the questions that make up the subscale.
16 weeks
Secondary Outcomes (1)
Secondary assessments of efficacy will be assessed via: The change from baseline in the CY-BOCS, CGI-I, SRS, SCQ.

Interventions
There is evidence of a relationship between ASD symptomatology and immune dysfunction suggests that immunomodulatory treatments effective in other autoimmune disorders might be investigated in ASD, including Trichuris Ova Suis (TSO), a helminth porcine whipworm
