Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In this Phase 1b open-label prospective clinical trial, patients with relapsing-remitting MS will undergo FMT of FMP30 (donor stool) via colonoscopy and immunological efficacy endpoints will be assessed at various time points. The active phase of the study will continue for 12 weeks post-FMT with safety and biomarker (engraftment) follow-up for 48 weeks. A parallel observational control arm of MS patients who otherwise satisfy study inclusion criteria based on their MS phenotype, demographics, disease duration and prior use of allowable MS therapies, will be recruited as a comparison observational group to measure stability of stool and serum immunological measures. The study duration for the Observational Control Arm is 12 weeks.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In this Phase 1b open-label prospective clinical trial, patients with relapsing- remitting MS will undergo FMT of FMP30 (donor stool) via colonoscopy and immunological efficacy endpoints will be assessed at various time points. The active phase of the study will continue for 12 weeks post-FMT with safety and biomarker (engraftment) follow-up for 48 weeks. A parallel observational control arm of MS patients who otherwise satisfy study inclusion criteria based on their MS phenotype, demographics, disease duration and prior use of allowable MS therapies, will be recruited as a comparison observational group to measure stability of stool and serum immunological measures.

The primary hypotheses are that:

1. FMT will be safe and tolerable in patients with MS.
2. FMT preceded by antibiotic preconditioning will lead to a change in fecal microbiota community structure

Secondary hypotheses are that:

1. FMT preceded by antibiotic preconditioning will induce a favorable shift from pro-inflammatory to immunomodulatory T cell profiles in patients with relapsing-remitting MS
2. That engraftment will not appreciably decay over time
3. That FMT will favorably change humoral function
4. That FMT will favorably influence short-term clinical and radiological endpoints.

FMP30 donor stool will be obtained from OpenBiome (Somerville, MA; OpenBiome.org), an established nonprofit stool bank with stringent safety protocols and quality control. Donor stool will be obtained from donors without MS and without other known autoimmune diseases and will be screened for transmissible pathogens. In collaboration with OpenBiome, UCSF will additionally screen donor stool on in vitro assays for immunological properties thought to be favorable in MS, including decreasing TH17 and increasing T regulatory cells, in order to select the final donor stool for to be used in this study for FMT. UCSF will obtain an IND from the FDA for FMT of FMP30 donor stool in MS.

After providing written informed consent and reviewing inclusion and exclusion criteria, subjects will participate in either the FMT Treatment Arm or the Observational Control Arm.

Subjects in the FMT Treatment Arm will first undergo screening assessments according to the study schedule of activities and provide blood samples for eligibility and research, and stool samples for research. Subjects who pass screening will have their pre-treatment baseline visit with 21 days of their screening visit where they will have an MRI, safety and biomarker research blood sample collection, stool sample collection for research, complete study activities according to the study visit schedule, be given antibiotics, bowel preparation, a medication compliance diary and directions on when and how to start the antibiotics and bowel preparation before their scheduled FMT colonoscopy procedure.

The week before their Baseline FMT visit, subjects will be contacted by study staff to initiate an oral antibiotic regimen for 5 days to precondition the gut for FMT and optimize engraftment of the donor microbiome. Study staff will ensure that the subjects understand how to complete their oral antibiotic regimen, compliance diary, and bowel preparation correctly.

At the study Baseline Visit, following standard bowel preparation for colonoscopy, subjects will then undergo colonoscopy with FMT of FMP30 by an experienced gastroenterologist. Subjects will return for scheduled assessments of stool and blood sampling, questionnaires, physical examination and MS rating scales, and follow-up MRI for 12 weeks, with additional safety and biomarker blood sample collection, and followed at weeks 24, 36 and 48. The active study time of 12 weeks was designed to be short to minimize time off MS disease modifying therapies (should the subject wish to go on a MS disease modifying therapy).

Subjects participating in the Observational Control Arm will not undergo the interventional FMT treatment. Participants in this arm will have a total of 5 visits over the course of 12 weeks. At the Screening/Baseline visit, subjects will provide blood and stool samples for research along with other study activities according to the study visit schedule. Subjects will mail in a stool sample at week 2 and come in for follow-up visits at weeks 4, 8 and 12.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Interventional FMT Treatment Arm

After providing written informed consent, subjects will undergo screening and baseline assessments of stool and blood sampling, questionnaires, physical examination, MS rating scales, and MRI. Subjects will then initiate an oral antibiotic regimen for 5 days to precondition the gut for the Fecal Microbiota Transplantation (FMT) of FMP30 donor stool and optimize engraftment of the FMP30 donor stool microbiome. Following standard bowel preparation for colonoscopy, subjects will undergo the FMT procedure by an experienced gastroenterologist. Subjects will return for scheduled assessments and follow-up MRI for 12 weeks, with additional safety and biomarker follow-up for 36 weeks.

The active study time is designed to be short (12 weeks active phase) to minimize time not on other MS disease modifying therapy (DMT). This arm of the study will last for approximately 52 weeks total (4 weeks of screening + 12 weeks active treatment phase + 36 weeks of safety follow up).

Group Type EXPERIMENTAL

FMP30 Donor Stool

Intervention Type DRUG

FMP30 is manufactured by the non-profit stool bank Openbiome. Each FMP30 filtered donor stool engraftment has approximately 12.5g of stool per 30mL of normal saline. It is homogenized in sterile normal saline.

Fecal Microbiota Transplantation (FMT) of FMP30 Donor Stool

Intervention Type PROCEDURE

Three doses of filtered donor stool engraftments homogenized in sterile normal saline (FMP30), obtained from the non-profit stool bank OpenBiome, will be administered via colonoscopy in patients with Relapsing-Remitting Multiple Sclerosis. FMT dosage via colonoscopy may include a lower amount of transplanted stool at the discretion of the study gastroenterologist if there are any peri-procedural safety or technical considerations. Total FMT dose (in milliliters) will be documented.

Observational Control Arm

Subjects, who otherwise satisfy study inclusion criteria based on their MS phenotype, demographics, disease duration and prior use of allowable MS therapies, will be recruited as a comparison observational group to measure stability of stool and serum immunological measures.

After providing written informed consent, subjects will undergo screening and baseline assessments, including collection of blood and stool samples, demographic data collection, concomitant medication review, and an MS Relapse assessment. At week 2, subjects will mail in stool samples with a prepaid air bill and packaging. Weeks 4, 8, and 12 assessments will include concomitant medication review, relapse assessment, and blood and stool collection.

The duration of the study for the observational control arm will last for 12 weeks. All study procedures will be performed at the University of California, San Francisco.
