Brief Summary
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.

Outcome Measures
Primary Outcomes (1)
Percentage of Participants Who Achieved a Clinical Response at Week 12
Clinical response is defined as a reduction in the Mayo score of at least 3 points and at least a 30% reduction from Baseline, along with either a decrease from Baseline in the rectal bleeding subscore of more than 1 point or a rectal bleeding subscore of 0 or 1.
Week 12
Secondary Outcomes (7)
Percent of Participants Who Achieved Remission at Week 12
Week 12
Percent of Participants With Healed Colonic Mucosa at Week 12
Week 12
Percent of Participants With a Modified Clinical Response
From Day 0 through time of first clinical response or end of follow-up, whichever comes first, up to 12 Weeks
Time to Modified Clinical Response
From Baseline through the day that modified clinical response is reached. Week 16 is the last visit that the modified Mayo score is assessed.
Percent of Participants With Colonoscopic Evidence of Visible Worm
From Day 0 through end of follow-up, up to 36 weeks
- +2 more secondary outcomes
Study Arms (2)
Trichuris suis ova (TSO)
EXPERIMENTALSix doses of TSO orally over a ten-week period
Placebo
PLACEBO COMPARATORSix doses of TSO placebo orally over a ten-week period
Interventions
Six doses of TSO orally over a ten-week period (e.g., every 2 weeks x 10 weeks for a total of 6 total doses)
Six doses of TSO placebo orally over a ten-week period (e.g., every 2 weeks x 10 weeks for a total of 6 total doses)
Eligibility Criteria
You may qualify if:
- Subject has provided written informed consent
- 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.
- Mayo score \>/= 4, as scored at Screen 2
- If taking the following medications at Screen 1, subjects must meet the following criteria:
- Oral Corticosteroids: stable treatment for at least 4 weeks prior to Day 0 with a maximum dose equivalent to \<\\=15 mg/day of prednisone
- 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
- Aminosalicylates: stable oral doses up to 4.8 g/day for at least 4 weeks prior to Day 0.
You may not qualify if:
- Subjects whose UC is anticipated to require surgical, endoscopic, or radiologic intervention during study participation
- Uncontrolled GI bleeding
- Subjects who have disease limited to the rectum (maximum disease extent of less than 15 cm)
- Women who are pregnant, breast-feeding, or planning to become pregnant during the study. All women of childbearing potential must have a negative serum pregnancy test at Screen 2 prior to randomization of treatment.
- Women of childbearing potential not using adequate birth control measures (e.g., total abstinence, oral contraceptives, intrauterine device, barrier method with spermicide, surgical sterilization, Depo-Provera, or hormonal implants).
- Current or recent serious systemic disorder including clinically significant impairment in cardiac, pulmonary, liver, renal, endocrine, hematologic, or neurologic function, based on investigator discretion
- Subjects currently receiving the following concomitant medications:
- Prednisone or its equivalent at unstable doses or at doses exceeding 15 mg/day within 4 weeks prior to Day 0
- Local steroids such as budesonide, Colifoam, or Predsol enemas within 2 weeks prior to Screen 2
- Topical therapies, either mesalamine or steroids, taken within 2 weeks of Screen 2
- Non-steroidal anti-inflammatory drugs (NSAIDs), Cyclooxygenase (COX)-2 inhibitors, or aspirin \>100 mg/day within 2 weeks prior to Screen 2
- Tumor necrosis factor (TNF)-alpha inhibitors including but not limited to infliximab (Remicade) or adalimumab (Humira) within 12 weeks of Day 0
- Any biological agent within 12 weeks of Day 0
- Metronidazole within 4 weeks of Day 0
- Receipt of any investigational agent within the 12 weeks prior to Day 0
- +22 more criteria
