An AI-powered Virtual Reality Brief Intervention for Hospitalized Patients With Alcohol-Associated Liver Disease (SOBER-VR)

Alcohol-associated liver disease (ALD) is a leading cause of preventable liver-related morbidity and mortality, with hospitalizations for ALD increasing significantly in recent years. Many patients with ALD and active alcohol use disorder (AUD) are discharged from the hospital without receiving evidence-based behavioral interventions, despite hospitalization representing a teachable moment when patients may be more motivated to change. Psychosocial support in this setting is often limited by short inpatient stays, provider shortages, and workflow barriers. Novel digital health approaches are needed to increase access to structured, personalized behavioral support during hospitalization. This project aims to assess the feasibility, usability, and clinical relevance of SOBER-VR, a virtual reality (VR) and artificial intelligence (AI)-powered digital therapeutic that delivers motivational interviewing (MI) to hospitalized patients with ALD and active alcohol use. SOBER-VR uses immersive VR to enhance emotional salience and a large language model (LLM)-driven conversational agent to simulate reflective, MI-consistent interactions. The intervention is brief (10-15 minutes), self-guided, and delivered using sanitized, standalone VR headsets with real-time support from trained staff. Using the NIH ORBIT Model for behavioral intervention development, this Phase Ib single-arm feasibility study will recruit 30 hospitalized patients with ALD and active alcohol use. Participants will use SOBER-VR during their inpatient stay and complete structured assessments post-discharge. The study will evaluate feasibility (recruitment, engagement, and retention), acceptability, usability, and safety of SOBER-VR. Preliminary signals of clinical impact, such as readiness to change, attitude to AUD treatment, among others, will also be explored.

RESTORE TRIAL: Study of the Efficacy and Safety of Pemvidutide in the Treatment of Alcohol-Associated Liver Disease (ALD)

This is a Phase 2, multicenter, randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of pemvidutide in subjects with ALD.

Pomegranate Dietary Supplements in AUD and ALD

The goal of this project is to determine an individual's ability to generate active gut microbial metabolites called urolithins upon consumption of pomegranate dietary supplements. Recent publications have reported that urolithins are the major active metabolites responsible for the beneficial effects of eating pomegranates, berries, or walnuts. However, the production of urolithins from the parent compound ellagic acid (EA) is dependent upon the presence of certain bacteria in the human gut. In this trial, we propose to investigate variations in gut microbiota and their capacity to metabolize pomegranate dietary supplements (PDS) into active urolithins. We will measure the levels of urolithins in blood as well as inflammatory cytokines in plasma samples upon consumption of PDS.

Implementation Facilitation Pilot for Alcohol Use Disorder (AUD) in Alcohol-associated Liver Disease (ALD)

The goal of this project is to improve provision of integrated medications for alcohol use disorder (MAUD) with brief counseling for patients with alcohol use disorder (AUD) and alcohol-associated liver disease (ALD) in hepatology clinics. There are many benefits of AUD treatment among patients with AUD and ALD such as reduction in liver-related complications and hepatology clinicians providing this care in an integrated fashion can improve access and uptake.

Financial Rewards for Reducing Alcohol Use in Patients With Liver Disease

This study tests whether providing financial rewards based on a blood test result can help people with alcohol-associated liver disease (ALD) stop or reduce their drinking. The blood test is called phosphatidylethanol (PEth), which can detect alcohol use over the past three to four weeks. The financial reward program is called contingency management (CM). The study has two parts. Part 1 involves one-time interviews and surveys with patients and healthcare providers to understand how a PEth-based CM program could best be delivered in a liver disease clinic. Part 2 is a pilot randomized controlled trial (the REINFORCE Trial) in which participants are randomly assigned to one of two groups: (1) a rewards group that receives escalating financial incentives when PEth results show reduced or no alcohol use, or (2) a monitoring group that receives fixed payments regardless of PEth results. Both groups receive PEth testing and continue their usual medical care. The study will assess whether the rewards program improves alcohol abstinence and reduction at 12 and 24 weeks.'

LGG Supplementation in Patients With AUD and ALD

To test the efficacy of 6-month LGG compared to placebo in treating Alcoholic Use Disorder (AUD) and liver injury in Alcoholic Hepatitis (AH). And to evaluate the effects of LGG treatment compared to placebo on therapeutic-mechanistic markers of the gut-brain axis and pro-inflammatory activity in patients with AUD and moderate AH
