8 Hepatic Encephalopathy Trials

Power is an online platform that helps thousands of Hepatic Encephalopathy patients discover FDA-reviewed trials every day. Every trial we feature meets safety and ethical standards, giving patients an easy way to discover promising new treatments in the research stage.

This trial tests if rifaximin, an oral antibiotic, can delay brain problems in patients with liver cirrhosis and controlled fluid buildup by reducing harmful gut bacteria. Rifaximin has been shown to reduce the recurrence of brain-related issues and related hospitalizations.

This trial tests two treatments that reduce immune activity in children with severe, unexplained liver failure. The treatments work by calming the immune system to prevent it from harming the liver.

This research is studying how a food product (resistant potato starch) which is a dietary supplement made from potato starch affects the gut bacteria of people with cirrhosis and hepatic encephalopathy. The researchers in this study want to understand how potato starch works in the subject's body and how the body will react to it. Along with taking the study product participants health-related information and stool will be collected for this research study.

Readmission rates for patients with hepatic encephalopathy due to end stage liver disease are high. Hyperammonemia contributes significantly to encephalopathy and occurs because of impaired hepatic ureagenesis and increased skeletal muscle proteolysis. We propose a randomized, 6-month nutritional intervention in cirrhotic patients who have had at least 1 admission for hepatic encephalopathy within the last 6 months. We hypothesize that a combination of late evening and early morning protein supplement (Ensure Enlive) will decrease recurrent hepatic encephalopathy and consequent readmission rates by lowering skeletal muscle proteolysis and improved lean body mass.

A total of 40 patients taking proton pump inhibitors (PPIs) who undergo transjugular intrahepatic portosystemic shunt (TIPS) creation as part of routine clinical care will be randomized in 1:1 fashion to either continue or discontinue their PPIs to determine whether these commonly used gastric acid suppressing agents increase risk of post-TIPS hepatic encephalopathy (HE). Patients will be assessed for symptoms of minimal HE (MHE), using the established psychometric hepatic encephalopathy score (PHES) battery of tests. MHE assessment will be conducted at two timepoints: at baseline prior to randomization and TIPS creation and approximately 4 weeks after randomization and TIPS creation. Stool samples will also be collected at both timepoints to allow characterization of the gastrointestinal (GI) tract microbiome using 16S rRNA sequencing. The pre to post-TIPS change in PHES scores will be compared between patients randomized to continue versus discontinue their PPIs. Quality of life (QOL) will also be assessed. Changes in the GI tract microbiome will be analyzed to determine whether this represents a potential biological mechanism linking PPI use with post-TIPS HE.

Hypothesis: Improvement in cognitive dysfunction with IV albumin in patients with cirrhosis with prior HE and MHE lasts for several weeks after albumin infusion has ended, and is due to persistent improvement in inflammatory markers, endothelial dysfunction, albumin function and gut microbial changes. This will be a single-arm, single-blind sequential trial of IV 25% albumin and IV saline over 8 weeks with biological sampling and cognitive and health related quality of life (HRQOL) testing with each subject acting as their own control.

Paracentesis vs. TIPS for Ascites

Los Angeles, California
For this study, the investigators will be collecting data based on patients' random selection to two different approved standard of care treatments for ascites: Subjects will get randomized into either Group A: Large Volume Paracentesis (LVP) with albumin infusion, or Group B: an early transjugular intrahepatic portosystemic shunt (TIPS) procedure.

This trial is testing whether giving healthy gut bacteria from a donor to patients with advanced liver disease can help improve their brain function. The treatment involves using stool from healthy people to replace unhealthy bacteria in the patients' guts. The goal is to see if this can help reduce confusion caused by hepatic encephalopathy.

Frequently Asked Questions

How much do Hepatic Encephalopathy clinical trials pay?

Each trial will compensate patients a different amount, but $50-100 for each visit is a fairly common range for Phase 2–4 trials (Phase 1 trials often pay substantially more). Further, most trials will cover the costs of a travel to-and-from the clinic.

How do Hepatic Encephalopathy clinical trials work?

After a researcher reviews your profile, they may choose to invite you in to a screening appointment, where they'll determine if you meet 100% of the eligibility requirements. If you do, you'll be sorted into one of the treatment groups, and receive your study drug. For some trials, there is a chance you'll receive a placebo. Across Hepatic Encephalopathy trials 30% of clinical trials have a placebo. Typically, you'll be required to check-in with the clinic every month or so. The average trial length for Hepatic Encephalopathy is 12 months.

How do I participate in a study as a "healthy volunteer"?

Not all studies recruit healthy volunteers: usually, Phase 1 studies do. Participating as a healthy volunteer means you will go to a research facility several times over a few days or weeks to receive a dose of either the test treatment or a "placebo," which is a harmless substance that helps researchers compare results. You will have routine tests during these visits, and you'll be compensated for your time and travel, with the number of appointments and details varying by study.

What does the "phase" of a clinical trial mean?

The phase of a trial reveals what stage the drug is in to get approval for a specific condition. Phase 1 trials are the trials to collect safety data in humans. Phase 2 trials are those where the drug has some data showing safety in humans, but where further human data is needed on drug effectiveness. Phase 3 trials are in the final step before approval. The drug already has data showing both safety and effectiveness. As a general rule, Phase 3 trials are more promising than Phase 2, and Phase 2 trials are more promising than phase 1.

Do I need to be insured to participate in a Hepatic Encephalopathy medical study ?

Clinical trials are almost always free to participants, and so do not require insurance. The only exception here are trials focused on cancer, because only a small part of the typical treatment plan is actually experimental. For these cancer trials, participants typically need insurance to cover all the non-experimental components.

What are the newest Hepatic Encephalopathy clinical trials ?

Most recently, we added Resistant Potato Starch for Liver Cirrhosis, Albumin for Hepatic Encephalopathy and Rifaximin for Hepatic Encephalopathy to the Power online platform.
