The purpose of this study is to evaluate the safety and effectiveness of trichuris suis ova (TSO) in ulcerative colitis (UC). We will look at how TSO affects the body's immune response and if there are related changes in participants' UC.

The cause of UC is not well understood. It is believed to be caused from an abnormal immune response to the normal bacteria that live in the gut (intestines and colon). This response acts as an "attack" on the healthy tissue of the bowel by a person's own immune cells which leads to disease.

It is well known that autoimmune diseases such as IBD, asthma, diabetes, and multiple sclerosis are more common in industrialized, well-developed countries with better sanitation and hygiene, as in the United States. These "cleaner" environments reduce exposure to germs and parasites naturally found in the environment. This reduced exposure may trigger responses in the body that make people more prone to diseases such as UC. People in non-industrialized countries and the tropics, where parasites are common, rarely develop these diseases. This observation has led researchers to want to better understand the relationship between the lack of natural bacteria in the gut and the onset of autoimmune diseases like as UC.

Primary Outcome Measures:
  • Percentage of Subjects who Achieve a Clinical Response [ Time Frame: 12 Weeks ] [ Designated as safety issue: Yes ]
    Clinical response will be defined as a reduction in Mayo score of ≥ 3 and ≥ 30% reduction from baseline, along with either a decrease from baseline in rectal bleeding sub-score of > 1 point or absolute rectal bleeding score of 0 or 1.

Secondary Outcome Measures:
  • Percentage of Subjects in Each Study Arm Achieving Remission [ Time Frame: 12 Weeks ] [ Designated as safety issue: Yes ]
    Percentage of subjects in each study arm who achieve a remission at Week 12, where remission is defined as Mayo score of ≤ 1 with absence of rectal bleeding and endoscopy score of 0 or 1.

  • Percentage of Subjects in Each Study Arm with Healed Colonic Tissue [ Time Frame: 12 Weeks ] [ Designated as safety issue: Yes ]
    Percentage of subjects in each study arm with healed colonic mucosa at Week 12, where healed colonic mucosa is defined as a Mayo endoscopy score of 0 or 1.

  • Time to Reach a Modified Clinical Response [ Time Frame: Up to 12 Weeks ] [ Designated as safety issue: Yes ]
    Time to reach a modified clinical response, where modified clinical response is defined as a reduction in the modified Mayo score of ≥ 2 from baseline (i.e., minus the endoscopy component).

  • Percentage of Subjects Each Study Arm with Colonoscopic Evidence of a Visible Worm (luminal or attached) [ Time Frame: Baseline to Week 36 ] [ Designated as safety issue: No ]
  • Percentage of Subjects Each Study Arm with Increase in Diarrhea [ Time Frame: Baseline to Week 36 ] [ Designated as safety issue: Yes ]
    The percentage of subjects experiencing an increase in diarrhea, as measured by the Mayo Score's Stool Frequency score.

  • Percentage of Subjects in Each Study Arm Requiring Increased Medications to Treat UC [ Time Frame: Baseline to Week 36 ] [ Designated as safety issue: Yes ]
    Percentage of subjects who require dose-escalation of concurrent medications or need rescue medications to treat UC.

Arms Assigned Interventions
Experimental: TSO 7500 Biological: Trichuris suis ova (TSO)
TSO 7500: 7500 embryonated, viable TSO every 2 weeks x 10 weeks (6 total doses)
Other Name: T. suis ova
Placebo Comparator: Placebo Biological: Placebo
15 mL aqueous solution


Ages Eligible for Study:   18 Years to 70 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Subject has provided written informed consent
  2. Diagnosis of UC (newly diagnosed or established patients) as determined by medical history, endoscopic and histological confirmation with the proximal disease extent limited to the left colon (distal to the splenic flexure), and accessible by flexible sigmoidoscopy. Patients with left-sided disease and the presence of a periappendiceal red patch (limited cecal inflammation) will be eligible as long as there is no intervening evidence of colitis between the cecal base and the upper boundary of inflammation in the left colon.
  3. Mayo score ≥ 4, as scored at Screen 2
  4. If taking the following medications at Screen 1, subjects must meet the following criteria:

    1. Oral Corticosteroids: stable treatment for at least 4 weeks prior to Day 0 with a maximum dose equivalent to ≤ 15 mg/day of prednisone
    2. Immunosuppressants (azathioprine (AZA) or 6-mercaptopurine (6-MP)): treatment for at least 12 weeks with a stable dose, not exceeding 2.5 mg/kg/day of AZA or 1.5 mg/kg/day of 6-MP, during the 4 weeks prior to Day 0
    3. Aminosalicylates: stable oral doses up to 4.8 g/day for at least 4 weeks prior to Day 0

Exclusion Criteria:

  1. Subjects whose UC is anticipated to require surgical, endoscopic, or radiologic intervention during study participation
