- •2. Male or non-pregnant female patients 18-65 years of age, inclusive
- •3. A history of UC for at least 6 months prior to time of screening
- •4. All subjects must have clinical and endoscopic confirmed diagnosis of active mild to moderate UC with disease extension beyond the rectum (>12 cm from the ano-rectal junction)
- •?confirmed by obligatory colonoscopy/endoscopy at screening: full report to be available and score equal to or greater than 2 (at least moderate friability)
- •?Ulcerative Colitis Disease Activity Index [UCDAI] of 5-10, inclusive, as assessed on screening (based on retrospective recall by the subject over the previous 3 days) and confirmed after 7 days of baseline observation, before inclusion in the randomization procedure, and not improving more than 2 score points during this run-in period
- •5. Duration of current relapse < 6 weeks from screening (according to patient)
- •6. Oral mesalazine/sulfasalazine maintenance therapy (eqaul to or less than 2 g/day) for no less than 30 days prior to screening.
- •7. Females of childbearing potential require a negative urine pregnancy test and must agree to abstinence or to use prescription contraceptives and to use a barrier contraceptive device along with a spermicidal product for the duration of the study. Subjects who are surgically sterile, menopausal or using contraceptive implants prior to the study enrolment are not required to utilize dual contraceptive techniques
- •8. Otherwise in general good health as judged by the investigator
排除标准
- •1. Proctitis (equal to or less than 12 cm from the ano-rectal junction)
- •2. Indeterminate colitis
- •3. Crohn's disease
- •4. Previous colonic surgery
- •5. Severe or fulminant UC [UCDAI >10] or requiring hospitalization
- •6. Evidence of other forms of inflammatory bowel disease
- •7. Subjects with a new diagnosis of UC
- •8. Subjects who altered their mesalazine/sulfasalazine dosage (dose regimen or dose) in the previous 2 weeks before screening
- •9. Subjects with a positive stool culture for any enteric pathogens that is clinically significant, pathogenic ova or parasites, or a positive enzyme immunoassay (EIA) that is subsequently confirmed by a positive cytotoxin assay for C. difficile toxin
- •10. Subjects who have used the following medications within the specified period
- •-Loperamide and other anti-diarrheal agents, probiotics, antibiotics: 1 week wash-out during baseline period
- •-Non steroidal anti-inflammatory drugs (NSAIDs) and Cyclo-oxygenase-2 (COX-2) inhibitors, within 14 days from screening
- •-Oral and injectable steroids, within 30 days from screening
- •-Rectally administered mesalazine/sulfasalazine or other 5-ASAs or steroids, within 7 days from screening. Topical dermatological corticosteroids are not excluded
- •-Antivirals or antifungals within 30 days
- •-Immunomodulating/suppressing drugs or biologicals (including anti TNF-α, cyclosporine, thalidomide, methotrexate) within 2 month
- •-Sulfasalazine or mesalazine at higher dose than for maintenance treatment (higher than 2g/day)
- •11. Failing to respond to steroids within the previous year prior to screening
- •12. Subjects who have any other clinically significant disease(s) which, in the opinion of the investigator, could compromise the subject?s involvement in the study or overall interpretation of the data, such as mental/emotional disorder, dysplasia or cancer, HIV, uncontrolled hematologic, renal, hepatic, metabolic pulmonary or cardiovascular disease, active alcohol or drug abuse
- •13. Needing enemas to treat their disease or to maintain remission
- •14. Subjects with abnormal laboratory values at admission which are clinically significant by the investigator (outlier values outside the normal values are allowed and to be marked as ?NCS? if considered Non-Clinically Significant (NCS) by the investigator based on the nature of the disease, quite some UC patients having an aberrant immune response and abnormal laboratory values due to the impaired absorption, and blood loss)
- •15. Subjects whose UCDAI score decreases ≥2 during the 7-day run-in period
- •16. Allergy to aspirin or salicylate derivatives
- •17. Subject with a history of drug allergy in general or hypersensitivity to probiotics
- •18. Participation in another clinical study within the 3 months prior to screening
- •19. Inability to comply with the protocol requirements or to fill in the diary cards
- •20. Pregnancy or breast-feeding women or women of child-bearing potential not agreeing to birth control
