Inclusion Criteria

1. Have read the Information for the Patient and signed the Informed Consent Form.
2. Age comprised between 18 and 75 included.
3. Diagnosis of active ulcerative colitis since at least 4 weeks as confirmed endoscopically (pancolonoscopy) and histologically. A new pancolonoscopy is required if documented evidence of having performed it within the previous 12 months is not available. If available, only a new colonoscopy for the visualization of the affected part of the colon is required for the evaluation of the baseline DAI score.
4. Disease Activity Index comprised between 3 and 6, inclusive (mild ulcerative colitis), with rectal bleeding sub-score of at least 1.
5. Stable background oral aminosalycilates (mesalazine, balsalazide, olsalazine) or sulfasalazine standard therapy for greater than or equal to 4 weeks prior to screening assessments.
6. If female, not pregnant or nursing.
7. For women of childbearing potential (WOCBP), willingness to avoid a pregnancy during the treatment period and for at least 4 weeks from the last dose of drug. A WOCBP is defined as any female who has experienced menarche and who has not ndergone
successful surgical sterilisation (hysterectomy, bilateral tubal ligation or bilateral ovariectomy) or is not postmenopausal (defined as amenorrhoea >12 consecutive months). WOCBP should use an efficient method of birth control for the entire duration of the trial and until the first menses after a 30-day period after the last dose of trial medication. They must be
on a stable regimen, for at least 1 month, of oral contraceptives, contraceptive implant or depot injection, contraceptive patch, intrauterine device (IUD), condom and spermicidal agent, or diaphragm and spermicidal agent. The patient will be informed about the
result of the pregnancy test and of the allowed method of contraception
and its duration
Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range 444
F.1.3 Elderly (>=65 years) yes
F.1.3.1 Number of subjects for this age range 0

Exclusion Criteria

1. Crohn’s disease and indeterminate colitis.
2. Current or previous (in the last 10 days preceding the screening) use of systemic corticosteroids.
3. Use of systemic antibiotics in the last 10 days preceding the screening.
4. Use of systemic NSAIDs on a repeat basis in the last 10 days preceding the screening.
5. Use of probiotics started within 10 days preceding the screening. A stable regimen from at least 10 days prior to screening is allowed but the patient must be willing to continue up to the end of the study.
6. Use of immunosuppressants or biological agents within the last 6 weeks preceding the screening.
7. Stool culture positive for enteric pathogens (eg, Shigella, Salmonella, Yersinia, Campylobacter) or toxins (C.difficile).
8. Significantly impaired liver, renal, pulmonary or cardiovascular function as assessed by the investigator.
9. History of colon resection.
10. Diverticulitis, symptomatic diverticulosis.
11. Active peptic ulcer disease.
12. Proctitis (extent of inflammation <15 cm from the anus).
13. Bleeding disorders
14. Rectal therapy with any therapeutic enemas or suppositories with the exception of those required for endoscopy during the 10 days preceding the screening.
15. Active or chronic infection(s) or malignancies.
16. Known hypersensitivity to the active ingredient and excipients of the study drug.
17. Simultaneous participation in another clinical trial, or participation in any clinical trial involving investigational drugs within 3 months from enrolment into the present study.

Primary Outcome Measures

Name	Time	Method
Main Objective: Compare the two treatment groups (ST 261 modified release<br>tablets 1g/die vs. placebo) with respect to the proportion of patients with disease remission at the end of the 8 weeks of treatment<br>Evaluation of safety and tolerability of ST 261;Secondary Objective: Maintenance of remission after four weeks of treatment interruption, the histological changes, the disease symptoms (sub-scores) improvement and the overall quality of life as measured by the Short Inflammatory Bowel Disease Questionnaire (SIBDQ).;Primary end point(s): The primary endpoint will be the clinical/endoscopic remission defined as a Disease Activity Index at the end of treatment = 2 with rectal bleeding sub-score = 0 and no other individual sub-score >1.<br>;Timepoint(s) of evaluation of this end point: Disease Activity Index at the end of treatment = 2 with rectal bleeding sub-score = 0 and no other individual sub-score >1.<br>
