Summary

This trial will test the safety and effectiveness of a treatment called microbiota transplant therapy (MTT) in patients with pulmonary arterial hypertension (PAH). Patients will receive capsules containing healthy intestinal bacteria, along

Who is the study for?
This trial is for adults aged 18-75 with pulmonary arterial hypertension (PAH) who have been on stable PAH treatment for at least a month. Participants must be able to swallow capsules, provide blood and stool samples, and commit to the study's schedule including follow-ups.
What is being tested?
The trial tests microbiota transplant therapy (MTT) with antibiotic preconditioning and fiber supplementation versus placebo in PAH patients. It aims to assess safety, feasibility, and how the body processes MTT. Patients are randomly assigned to one of three groups: MTT plus fiber, MTT plus placebo fiber or double placebo.
What are the potential side effects?
Potential side effects may include digestive discomfort due to antibiotics or fiber supplements, reactions from the microbiota capsules such as bloating or gas, and any unforeseen effects related to altering gut bacteria.
