Safety and Efficacy of Heterologous FMT by SQIMC-md Capsule in Mild-moderate Ulcerative Colitis Patients (SQIMC-md)

2019年8月8日 更新者：Tongji Hospital

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-a Multi-center Double-blind RCT Trial

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.

详细说明

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.

主要结果指标

措施说明
大体时间
Clinical response rate at week 8 after SQIMC-md treatment.
大体时间：8 weeks

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:

  1. Stool frequency: 0-3
  2. Rectal bleeding: 0-3
  3. Mayo endoscopic score: 0-3
  4. 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
