Interventions
Biological: Fecal Microbial Transplantation
Registration Number
NCT03267238
Lead Sponsor

Brief Summary

Fecal Microbiota Transplantation will be offered to eligible Crohn's disease patient as Investigational New Drug treatment

Detailed Description

The following hypothesis will be tested in this study:

1. Fecal microbiota transplantation is a safe, tolerable procedure.

2. The fecal microbial diversity, composition and function in stool recipients after fecal transplantation will change to a similar microbial diversity, composition and functionality as found in donor stool.

Primary objectives:

1. To determine the short term safety and tolerability of fecal microbiota transplantation up to 12 weeks post-transplant in patients with Crohn's disease.

Secondary objectives:

1. To determine the long term safety and tolerability of fecal microbiota transplantation (FMT) up to one year post transplant in patients with Crohn's disease.

2. To compare microbial diversity in healthy donor stools compared to pre-FMT recipient stools collected from patients (recipients) with Crohn's disease.

3. To compare microbial composition in healthy donor stools compared to pre-FMT recipient stools from patients (recipients) with Crohn's disease.

4. To compare microbial function in healthy donor stools compared to pre-FMT recipient stools from patients (recipients) with Crohn's disease

5. To compare microbial diversity in healthy donor stools and pre-FMT recipient stools with 1 week post-transplant recipient stool samples collected from patients (recipients) with Crohn's disease.

6. To compare microbial composition in healthy donor stools and pre-FMT recipient stools with 1 week post-transplant recipient stool samples collected from patients (recipients) with Crohn's disease.

7. To compare microbial function in healthy donor stools and pre-FMT recipient stools with 1 week post-transplant recipient stool samples collected from patients (recipients) with Crohn's disease.

8. To compare microbial diversity in healthy donor stools and pre-FMT recipient stools with 12 week post transplant recipient stool samples collected from patients (recipients) with Crohn's disease.

9. To compare microbial composition in healthy donor stools and pre-FMT recipient stools with 12 week post transplant recipient stool samples collected from patients (recipients) with Crohn's disease.

10. To compare microbial function in healthy donor stools and pre-FMT recipient stools with 12 week post transplant recipient stool samples collected from patients (recipients) with Crohn's disease.

11. Stool calprotectin levels will be measured in the recipient at baseline pre-FMT, 1 week and 12 weeks post FMT to determine if FMT causes a statistically significant change.

Number of participants with treatment-related adverse events as assessed by CTCAE v4.0.5 years

Number of participants with treatment-related adverse events with grade greater than 2 within one year after FMT will be reported.

Secondary Outcome Measures
NameTimeMethod
To measure the effect of fecal microbial transplantation on microbial function using targeted metabolomic assays.6 years

Fecal samples will undergo extraction for targeted metabolomics analysis of short chain fatty acids (micrograms/gram stool) using gas chromatography-mass spectrometry, and of bile acids (microgram/gram stool) using liquid chromatography-mass spectrometry. A linear mixed model will be used to compare respectively short chain fatty acid and bile acid metabolites between each timepoint (FMT) and each disease group (Group). P-values less than 0.05 were considered as statistically significant.

To measure the effect of fecal microbial transplantation on microbial function using shotgun DNA metagenomic in healthy donor stools compared to pre-FMT, 1 week post FMT, and 12 weeks post-FMT recipient stools.6 years

Fecal DNA samples will undergo shotgun DNA metagenomics sequencing. After removing human sequences, the Reads per kilobase gene length (RKP) will be calculated using HUMANN2 software for individual bacterial proteins/enzymes and pathways. . A linear mixed model will be used to compare RPK associated with pathways and individual proteins between each timepoint (FMT) and each disease group (Group). P-values less than 0.05 were considered as statistically significant.Linear mixed models analyses on the RPK associated with individual genes and pathways will be analyzed using linear mixed models between timepoints before and after FMT \[pre-transplant recipient, 1-wk. post-FMT recipient, 3-mos. post-FMT recipient\] and each disease group, a generalized linear mixed model (GLMM) or generalized estimating equation (GEE) were used by taking the actual RPK as the outcomes that will be assumed to follow a negative binomial distribution.

Determine if FMT causes a statistically significant change in recipient fecal calprotectin levels6 years

Fecal calprotectin (microgram/gram stool) levels will be measured as in the recipient at baseline pre-FMT, 1 week, and 12 weeks post FMT. A linear mixed model will be used to compare fecal calprotectin levels between each timepoint (FMT) and each disease group (Group). P-values less than 0.05 were considered as statistically significant.

To measure the effect of fecal microbial transplantation on microbial function using bacterial metatranscriptomic sequencing6 years

Fecal RNA samples will undergo bacterial metatranscriptomic RNA sequencing. After removing human sequences, the Reads per kilobase transcript (RKP) will be calculated for individual bacterial proteins/enzymes and pathways. A linear mixed model will be used to compare RPK associated with pathways and individual proteins between each timepoint (FMT) and each disease group (Group). P-values less than 0.05 were considered as statistically significant.

To measure the effect of fecal microbial transplantation on microbial diversity in healthy donor stools compared to pre-FMT, 1 week post FMT, and 12 weeks post-FMT recipient stools.6 years

Fecal DNA samples will undergo V3-V4 16S rRNA sequencing. Operational taxonomic units (OTUs) will be produced by clustering sequences with identical taxonomic assignments. Alpha diversity indices (e.g. Chao1, Shannon complexity H, Shannon Evenness H/Hmax) will be calculated inferred through 1000 replicate resamplings using Explicet. Beta diversity (Bray-Curtis and Jaccard distances) will be calculated for the recipient Pre-FMT, 1 week post-FMT and 12 weeks post-FMT as compared to their pared donor using the adonis function in the R vegan package at the phyla, family and genus level. A linear mixed model will be used to compare alpha-diversity (ShannonH) and beta-diversity (Bray-Curtis and Jaccard distance) between each timepoint (FMT) and each disease group (Group). P-values less than 0.05 were considered as statistically significant.

To measure the effect of fecal microbial transplantation on microbial composition in healthy donor stools compared to pre-FMT, 1 week post FMT, and 12 weeks post-FMT recipient stools.6 years

Fecal DNA samples will undergo V3-V4 16S rRNA sequencing. . Operational taxonomic units (OTUs) will be produced by clustering sequences with identical taxonomic assignments. Linear mixed models analyses on individual OTUs at the genus level will be conducted on 105 OTUs after eliminating OTUs with an average relative abundance of \< 0.001% in the donor and recipient pre-FMT samples, and after discarding OTUs where more than 75% of the samples had a zero count. To compare the relative abundance of each OTU between timepoints before and after FMT \[pre-transplant recipient, 1-wk. post-FMT recipient, 3-mos. post-FMT recipient\] and each disease group, a generalized linear mixed model (GLMM) or generalized estimating equation (GEE) will be used by taking the actual counts of each OTU as the outcomes that were assumed to follow a negative binomial distribution. The p-values will be adjusted for multiple comparisons by the Bonferroni correction or by the Benjamin-Hochberg method (FDR \< 0.05).
