This is a randomized, double-blind, placebo-controlled, multicenter, and proof of concept study with a parallel group design to evaluate the safety and efficacy of oral Trichuris Suis Ova (TSO) suspension, as compared to placebo, in patients with moderately to severely active Crohn's disease. This study will also have an optional open-label extension for patients completing the double-blind phase of the study.
Biological: Trichuris suis ova (TSO)
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
||A Phase II Study to Evaluate the Efficacy and Safety of 12 Weeks of Treatment With Oral CNDO 201 Trichuris Suis Ova Suspension (TSO) as Compared to Placebo, Followed by a 12 Week Open-label Treatment Period in Patients With Moderately to Severely Active Crohn's Disease
Primary Outcome Measures:
- evaluate the effects of TSO on the induction of response in Crohn's disease, as measured primarily by Crohn's Disease Activity Index (CDAI) [ Time Frame: 12 weeks ] [ Designated as safety issue: Yes ]

| Estimated Primary Completion Date:
||November 2013 (Final data collection date for primary outcome measure)
Placebo Comparator: Placebo
Placebo: dose every 2 weeks X 10 weeks (up to 6 total doses)
Experimental: TSO 7500
Biological: Trichuris suis ova (TSO)
TSO 7500: 7500 embryonated, viable TSO every 2 weeks X 10 weeks (up to 6 total doses)
|Ages Eligible for Study:
||18 Years to 65 Years
|Genders Eligible for Study:

- Bowel surgery in past 6 months prior to Screening.
- Resection of more than 50 cm of the ileum.
- Current ileostomy or colostomy.
- Ongoing or active septic complications, is hospitalized or exhibiting signs of toxicity (sepsis), has symptomatic strictures, or impending obstruction or anticipating a need for blood transfusion for gastrointestinal bleeding or in whom surgical intervention may be imminent.
- Patient with gastrointestinal abscess or perforation.
- Patient with fistulae having a new onset within 2 months of Screening with moderate to severe local inflammation.
- Patient with history of colorectal cancer or colorectal dysplasia. Patients with completely resected sporadic adenomas may be enrolled.
- Patient requiring parenteral or tube feeding.
- Patient with current evidence of infectious colitis, e.g., Clostridium difficile, Amoebiasis, Giardia lamblia or stools positive for other enteric pathogens, ova or parasites at Screening.
- Female patient who is pregnant or breastfeeding or wishing to become pregnant during study participation or unwilling to use birth control.
