简要总结
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.
详细描述
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.

入选标准
- •Any gender; male or female; aged 18- 75 years old.
- •Severe alcoholic hepatitis defined as 2.1 Onset of jaundice within prior 8 weeks. 2.2 Ongoing alcohol consumption of >40 g/day (3 drinks) in females or >60 g/day (4 drinks) in males for 6 months or more, with less than 60 days of abstinence before the onset of jaundice. 2.3 Aspartate aminotransferase >50, Aspartate aminotransferase/Alanine aminotransferase ratio > 1.5, BUT both values <400 IU/L.
- •2.4 Serum total bilirubin >3.0 mg/dl. 2.5 MELD score >15 and/or Maddrey DF score of ≥32.
排除标准
- •Non-alcoholic related liver diseases.
- •Patients with swallowing dysfunction at risk of aspiration.
- •Patients at risk for or with known anatomic or functional gastrointestinal (GI) obstruction or who have undergone major intra-abdominal surgery in the last year.
- •Patients who have undergone placement of a portosystemic shunt, infection of which may require prolonged antibiotics.
- •Patients with any congenital or acquired immunodeficiency (Other than liver disease)
- •Uncontrolled infections, sepsis, or GI bleeding.
- •Presence of cancer especially patients with skin cancer who is receiving or may receive systemic chemotherapy or immunotherapy during the study period.
- •Underlying disease that might be exacerbated by proposed treatments (e.g. HCV, HBV, HIV, TB).
- •Serum creatinine >2.5 mg/dl at presentation.
- •Pregnant and breastfeeding patients.
- •Active use drug addiction.
- •PI thinks their participation would pose a health risk e.g. patients with very severe AH with MELD score >30 or Maddrey DF > 60 or patient will be getting liver transplantation imminently.
- •Any other major illness/ condition that in the investigators judgment, will substantially increase the risk to the participant.
研究组 & 干预措施
Intervention Arm
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.
干预措施: Fecal Microbiota Transplantation (Biological)
Placebo Arm
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.
干预措施: Placebo (Other)
