Clinical Trial Summary

This study aims to assess the safety and efficacy of heterologous fecal microbiota transplantation (FMT) by Standardized Quantitative multi-donor Intestinal Microbiota Capsule (SQIMC-md) in mild-moderate ulcerative colitis patients who fail to achieve clinical remission over 4 weeks after full dose 5-Aminosalicylic acid(5-ASA). Intestinal microbiota transplant for FMT will be prepared from multiple healthy donors and prepared by standardized procedure with fixed quantitative dosage. This strategy might offer a novel and safe therapeutic approach for these patients before step up to corticosteroid, immunosuppressant or biologics therapy.

Description:

All candidates for mild-moderate ulcerative colitis treated in Dept. Gastroenterology, Tongji Hospital, Tongji Medical College of HUST, the second Xiangya Hospital of central south university and the first affiliated Hospital of Zhengzhou University will be screened for study inclusion and exclusion criteria. All consenting patients will 2:1 randomized into SQIMC-md treatment group or Placebo group. Three dose of SQIMC-md capsule will be orally administrated on day1, day2 and day3. Follow-up will be performed every 4 weeks and last for 12weeks. Full dose of 5-ASA is orally administrated simultaneously during the study. Clinical data and outcome will be collected and documented in electronic case reported form (eCRF).

FMT DONORS:

Potential healthy adult stool donors (between 18 and 28 years of age) will be recruited by the research staff. They will be asked to volunteer for the screening and regularly supply stool samples according to the study protocol.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Clinical response rate at week 8 after SQIMC-md treatment.	Assess efficacy of SQIMC-md FMT treatment with the aid of the Mayo score for Ulcerative Colitis clinical disease severity and response rate at week 8 after SQIMC-md treatment.; Mayo score (Disease activity index) for Ulcerative Colitis. Total range for complete Mayo score 0-12 (sum from 4 subscales below) and partial Mayo score 0-9 (sum from 1,2 and 4 subscales below): Each subscale for mayo score: Stool frequency: 0-3; Rectal bleeding: 0-3; Mayo endoscopic score: 0-3; Estimation from physician: 0-3; Clinical response rate is defined as a decrease of = 3 points and at least 30% from baseline in the Mayo score, with an accompanying decrease of = 1 point in the subscore for rectal bleeding or an absolute subscore = 1 for rectal bleeding	8 weeks
Secondary	Incidence of Treatment-Emergent Adverse Events	safety of SQIMC-md FMT treatment by recording the incidence of adverse events.	12 weeks
Secondary	clinical response rate at week4 and week12	Assess the efficacy of SQIMC-md FMT by response rate at week4 and week12	week4 and week12
Secondary	the remission rate at week12	the remission rate at week12 with the aid of mayo score or partial Mayo score. Clinical remission rate at week 12 after treatment (clinical remission is defined as a Mayo score of = 2 points and no single score > 1 point	12 weeks
Secondary	Mean (or median) decrease of fecal calprotectin	Assess the efficacy of SQIMC-md FMT measured by the drop of fecal calprotectin.	12 weeks
Secondary	Mean (or median) change from baseline in Inflammatory Bowel Disease Questionnaire (IBDQ) total score and subscore at week 12	IBDQ includes 32 questions. The questions are grouped into four categories (subscore): Bowel symptoms (B), Systemic symptoms (S), Emotional function (E) and Social function (SF). Response options are consistently presented as seven-point scales (1-7). Total score is defined as the sum of subscore of four categories.	12 weeks
