Microbiome Therapy

Fecal Microbial Transplant for Atherosclerosis

Phase 1
Recruiting
Led By J. David Spence, M.D.
Research Sponsored by Western University, Canada
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial
Must have
Severe atherosclerosis, with total plaque area in the top quartile (>119 mm2), not explained by traditional risk factors in linear regression (residual score >= 2)
Be older than 18 years old
Must not have
Patients with moderate to severe renal failure (eGFR<50)
Patients with unstable angina
Timeline
Screening 3 weeks
Treatment Varies
Follow Up 6 weeks and 12 months

Summary

"This trial aims to treat patients with unexplained severe atherosclerosis by giving them fecal transplants from patients with a Protected phenotype. The goal is to see how this affects the intestinal microbiome and

Who is the study for?
This trial is for people with severe atherosclerosis, where plaque buildup in arteries isn't due to usual risk factors. Participants should have a high amount of plaque (top 25%) and not fit the typical profile for heart disease as assessed by doctors.
What is being tested?
The study tests if fecal microbial transplants from individuals resistant to artery plaque can improve gut bacteria in those with unexplained atherosclerosis, potentially lowering harmful metabolites like TMAO.
What are the potential side effects?
Potential side effects may include digestive discomfort, changes in bowel habits, and abdominal pain. There's also a risk of infection transmission through the transplant material.
