A Pilot Trial to Investigate the Safety and Efficacy of Intestinal Microbiome Transplant (MTT) in People With Amyotrophic Lateral Sclerosis

Status: Recruiting
Location: See location...
Intervention Type: Drug
Study Type: Interventional
Study Phase: Phase 1/Phase 2
SUMMARY

This is a 24-week study of intestinal microbiome transplant in people with ALS. All participants will be evaluated clinically in person for 4 visits. Blood and mailed/ fresh stool samples will also be collected. Blood samples will be used to determine changes in neurofilament light chain over time. Stool samples will be processed for microbiome analysis. Participants will have phone visits to further evaluate safety and tolerability. They will then undergo antibiotic conditioning and a standard bowel preparation before being assigned to the investigational product, MTP-101C .

Treatments
Experimental: MTP-101C administration
MTP-101C is a freeze-dried encapsulated universal donor microbiome-based formulation. Participants will ingest 2 capsules daily for 3 days then 1 capsule daily. This is preceded by antibiotic conditioning with a combination of vancomycin and neomycin, followed by a bowel purgative with magnesium citrate depending upon underlying comorbidities.
