Brief Summary:
Adolescent autism spectrum disorder subjects with associated GI symptoms will be randomized to receive oral dosing of CP101 capsules in Treatment Group I or matching placebo capsules in Treatment Group II. The purpose of this study is to demonstrate the safety and effectiveness of CP101 in subjects with ASD and associated GI symptoms.

Primary Outcome Measures :
  1. Childhoood Autism Rating Scales-2 (CARS-2) [ Time Frame: 24 weeks ]
    Two 15-item rating scales completed by the clinician (each designed for a different population); and an unscored Parent/Caregiver Questionnaire

Secondary Outcome Measures :
  1. Aberrant Behavior Checklist-2 (ABC-2) [ Time Frame: 55 weeks ]
    Scoring scale range from 1-3 for a 58 question, 5 behavior category assessments. All categories summed for individual total scores (7-48). Individual total scores determine severity (the higher, the more severe).

  2. Social Responsiveness Scale-2 (SRS-2) [ Time Frame: 55 weeks ]
    Total Score; Scores for 5 Treatment Subscales; Scores for 2 DSM-5 Compatible Subscales

  3. Parent Global Impressions-III (PGI-III) [ Time Frame: 55 weeks ]
    19 question assessment evaluating parent observations from "much worse" to "much better".

  4. Gastrointestinal Symptom Rating Scale (GSRS) [ Time Frame: 55 weeks ]
    Contains 15 items, uses a seven-graded Likert scale, where 1 represents the most positive option and 7 the most negative one.

  5. Gastrointestinal Stool & Symptom Questionnaire for Autism (GSSQA) [ Time Frame: 55 weeks ]
    17 item assessment evaluating GI symptoms on a scale from "Not at all" to "Almost always".

  6. Reynolds Intellectual Assessment Scales-2-Nonverbal (RIAS-2-NV) [ Time Frame: 55 weeks ]
    IQ test with 8 sub-categories. Scores from each category summed, then indexed

  7. Autism Diagnostic Interview-Revised (ADI-R) [ Time Frame: 55 weeks ]
    The ADI-R provides a diagnostic algorithm for autism as described in both the ICD-10 and DSM-IV. The instrument focuses on behavior in three main areas: qualities of reciprocal social interaction; communication and language; and restricted and repetitive, stereotyped interests and behaviors.
