Microbiome Modulation With Prebiotics in PTSD and Cirrhosis
NCT06464952 · View on ClinicalTrials.gov ↗
Study Summary
Despite medical advancements, PTSD remains a major issue in Veterans1. Current treatment strategies have relatively poor adherence. In patients with PTSD and cirrhosis, there is greater cognitive impairment as well as changes in gut microbiome structure and function2,3. In addition, when there is concomitant cirrhosis, medication-related treatment options become even narrower from a safety and tolerability perspective and cognitive issues pertaining to cirrhosis could impact participation3. Changes in gut microbiome in Veterans with cirrhosis and PTSD compared to those with cirrhosis without PTSD is characterized by a greater relative expression of pathobionts and reduction in stool microbiome diversity with reduction in bacteria that produce beneficial short chain fatty acids (SCFA)2. Modulation of the gut microbiome in patients with cirrhosis and PTSD may be an important therapeutic target. In prior studies with cirrhosis alone, microbial modulation using diet, antibiotics such as rifaximin, probiotics, and fecal microbiota transplant have improved gut microbial diversity and clinical outcomes in some cases4,5. In patients with cirrhosis without PTSD and in patients with PTSD without cirrhosis there is emerging evidence regarding prebiotics and other forms of gut microbial modulation. Prebiotics are such an example6. Prebiotics are natural fibers derived from carbohydrates and can be beneficial to gut microbiota (good bacteria in the gut)6. Resistant starches (RS) are dietary fiber prebiotics found naturally in many foods including potatoes, plantains, and legumes6,7. In addition to being highly accessible, RS have been shown to be well tolerated with few adverse reactions. While no studies of RS exist in PTSD + cirrhosis patients, a meta-analysis of RS in IBD has shown RS to be an effective treatment in both animal and clinical studies where improvements in clinical remission and reduced mucosal damage were found7. However, there is insufficient data regarding p

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT06464952
The ClinicalTrials.gov registry entry for NCT06464952 describes a study currently listed as recruiting. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 30 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Hunter Holmes Mcguire Veteran Affairs Medical Center, which has 7 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with PTSD appearing as the primary indexed condition, and to 2 interventions — of which Resistant potato starch is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT06464952 reports 1 study location spanning 1 distinct geographic area — top geographies include Virginia. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
