Safety Evaluation of Fecal Microbiota Transplantation in Severe Alcoholic Hepatitis

Fecal Microbiome Changes Characterization and Safety Evaluation After Oral Administration of Lyophilized Capsules Containing Microbiota Suspension in Severe Alcoholic Hepatitis Patients: Double Blinded, Randomized, Placebo-Controlled Study.

This is a single center, randomized, parallel assignment, and double-blind placebo-controlled pilot study to characterize the intestinal microbiome in patients with severe Alcoholic Hepatitis (SAH) and evaluate the safety and the trends in improvement of diversity of intestinal microbiome following administration of lyophilized capsules containing microbiota suspension from well screened health donors. The study aims to enroll 50 patients with SAH who will be randomly assigned in 1:1 where 25 patients will be assigned to receive orally administered lyophilized PRIM-DJ2727 and Standard of Care (SOC) and the other 25 patients will be assigned to receive placebo and SOC for 4 weeks.

Background: Alcoholic hepatitis (AH) is a major public health problem in the United States, caused by chronic alcohol consumption of more than 40-60 g/day. Approximately 5 million Americans are diagnosed with AH, contributing to 5% of US annual mortality. A 28-day mortality rate had been reported in 30 to 50% of patients with AH. Steroid therapy has been the mainstay treatment of patients with severe AH for the last 50 years. Yet, such treatment hasn't clearly result in improvement of liver indices and survival rates among AH patients. Moreover, the use of prednisolone was associated with significant side effects and has several contraindications. Alternative therapeutic approaches have been explored but with lack of effectiveness. On the other side, shortage of organs and cost for liver transplantation are major barriers for liver transplantation in patients with AH. There is a growing evidence suggesting that gut-derived bacterial endotoxins may play a role in alcohol-induced tissue injury and liver failure among heavy alcohol drinkers. This could be attributable to two factors: The first is decreased gastrointestinal motility. Ethanol can alter intestinal permeability by disrupting intercellular tight junctions and lead to GUT leak and translocation of the microbes. The second factor explain the association between microbiota and alcohol liver diseases is down-regulation of antimicrobial peptides induced by alterations in host immune responses in alcohol drinkers. One experimental study compared alcohol-sensitive mice (ASM) to alcohol-resistant mice (ARM). The study showed that ASM have reduced Bacteroidetes and increased level of Actinobacteria and Firmicutes and that performing fecal microbiota transplantation (FMT) from ARM to ASM yielded protection against Bacteroidetes depletion and against the alcohol-induced steatosis in ASM. Over the last few years, multiple studies have shown that FMT is safe and more effective in treatment of recurrent clostridium difficile than the standard medical treatment. The successful use of FMT in recurrent C. difficile, lead to multiple exploratory studies assessing safety and efficacy of FMT in multiple diseases especially gastrointestinal disorders, including Primary Sclerosing Cholangitis (PSC), Inflammatory Bowel Diseases (IBD), Liver cirrhosis and Hepatic Encephalopathy. These studies showed that FMT was safe and showed signs of effectiveness that requires larger Randomized control trials (RCTs) to confirm these findings. A Recent study by Indian investigators showed that modulation of intestinal microbiota has shown to improve survival in patients with severe AH. However, the study had multiple limitations, including absence of randomization, limited number of biochemical parameters and prognostic scores used, use of Nasoduodenal tube to deliver FMT and the lack of detail profiling of intestinal microbiome. Investigational Agent: PRIM-DJ2727(microbiota suspension)is an intestinal microbial suspension prepared form stool obtained from carefully and thoroughly screened healthy human donors. PRIM-DJ2727 is prepared from a standard amount of healthy human stool mixed with 0.85%NaCI(normal saline) and 2% mannitol. Microbiota from a single donor will be screened before lyophilization and encapsulation. The lyophilized capsules given for each treatment contain bacteria from 10g Filtered stool. Placebo will be identical to the investigational product but will not contain intestinal bacteria. This is a single center, randomized, parallel assignment, and double-blind placebo-controlled pilot study to be conducted in subjects with severe AH. Subjects with clinical diagnosis of severe alcoholic hepatitis (SAH) based on recommendation From the NIAAA Alcoholic Hepatitis Consortia criteria will be eligible. After screening, the investigators aim to enroll 50 patients with SAH who will be randomly assigned in 1:1 where 25 patients will be assigned to receive orally administered lyophilized PRIM-DJ2727 and Standard of Care (SOC) and the other 25 patients will be assigned to receive placebo and SOC for 4 weeks. This study is considered Pilot study due to small sample size as the investigators are using this Phase I study to assess the safety of the PRIM-DJ2727 Capsules in patients with Alcoholic hepatitis and to provide enough data to design and prepare for Phase II trial. A formal sample size has not been calculated as this study is not powered to establish significance. This is a pilot study aimed at characterizing the intestinal microbiome in patients with severe AH and evaluate the safety and the trends in improvement of diversity of intestinal microbiome following administration of lyophilized capsules containing microbiota suspension (PRIM-DJ2727 capsules) from well screened health donors.

Subjects will receive Standard of Care (SOC), based on AASLD/EASL guidelines and one dose of PRIM-DJ2727 (30 grams of stool/dose ~ 3 capsules) every day for a week followed by once weekly for 3 weeks, amounting to total 10 doses. PRIM-DJ2727 (microbiota suspension) is an intestinal microbial suspension prepared form stool obtained from carefully and thoroughly screened healthy human donors. It will be provided by University of Texas School of Public Health.

Subjects will receive Standard of Care (SOC), based on AASLD/EASL guidelines and one dose of Placebo every day for a week followed by once weekly for 3 weeks, amounting to total 10 doses. Placebo will be identical to the investigational product but will not contain active PRIM-DJ2727.

It's an intestinal microbial suspension prepared form stool obtained from carefully and thoroughly screened healthy human donors.
