アルコール関連肝炎の治療におけるジゴキシン (DIGIT-AlcHep)
アルコール関連肝炎（DIGIT-AlcHep）の治療におけるジゴキシン
Prospective, single center, open label, randomized controlled trial to explore whether digoxin treatment affects cytokine levels as biomarkers of inflammation in patients with acute alcohol associated hepatitis, digoxin administration and dose adjustment.
The study intervention will be intravenous digoxin (renal-based dosing for maximum of 28 days) versus no digoxin in an open-label 1:1 randomized allocation of patients with severe acute alcohol associated hepatitis.
調査の概要

介入・治療
詳細な説明
Severe alcohol associated hepatitis is a condition of acute on chronic immune liver dysfunction that is associated with high mortality, necessitating a search for drugs that may prove safe and efficacious in treating this disease. Pre-clinical studies suggest that digoxin, which is currently used for treating cardiac conditions, is also effective in improving alcohol-associated liver injury. To date, there have been no clinical studies of digoxin use in patients with alcohol associated hepatitis.
The primary objective of this randomized control study of digoxin versus no digoxin in patients with severe alcohol associated hepatitis is to explore whether digoxin treatment affects cytokine levels as biomarkers of inflammation in patients hospitalized with severe alcohol associated hepatitis.

説明
Inclusion Criteria:
1. Diagnosis of alcohol associated hepatitis based on clinical criteria or histologic evidence
-
Clinical criteria:
- Onset of jaundice (bilirubin >3 mg/dL) within the prior 8 weeks
- Regular alcohol use > 6 months, with intake of > 40 g/day (>280 g/week) for women; and > 60 g/day (>420 g/week) for men
- AST > 50 IU/l
- AST: ALT > 1.5 and both values < 400 IU/l
-
Histological evidence of alcohol associated hepatitis*
2. MDF >32 or MELD ≥ 20 to ≤ 35 on Day 0 of the trial
3. Age between 21 and 70 years, inclusive
* In patients with possible alcohol associated hepatitis with confounding factors such as possible ischemic hepatitis, possible DILI, uncertain history of alcohol use, or atypical/abnormal laboratory tests (e.g., AST < 50 IU/IU/L or > 400 IU/IU/L, AST/ALT ratio < 1.5), antinuclearantibody > 1:160 or SMA > 1:80, standard of care liver biopsy may be performed as per discretion of the primary attending physician to confirm alcohol associated hepatitis and exclude competing etiologies. The decision to perform liver biopsy will be made by the primary team and will occur regardless of the study. As per current SOC, a liver biopsy may be obtained to confirm suspected alcohol-associated hepatitis and to rule out other potential etiologies of liver disease.
If a liver biopsy is performed for clinically indicated reasons, we will store liver tissue that is left over after the portion needed for the primary indication has been identified.

実験的：Arm A: Digoxin
In the digoxin arm, the intervention to be administered will be intravenous digoxin dosed by weight and by renal function using an adaption of the established FDA nomogram. Participants randomized to digoxin will receive an intravenous digoxin loading dose administered in 3 doses over 24 hours starting on Day 1. Digoxin levels will be monitored daily throughout the participant's hospital stay, to a maximum of 28 days. Digoxin will be discontinued at the time discharge if before 28 days. |
Loading dose: the total loading dose of digoxin will be determined using the Loading nomogram. The FDA-recommended total IV digoxin loading dose range is 8 to 12 mcg/kg. The lowest recommended dose of 8 mcg/kg was used in constructing the digoxin Loading nomogram that will be used in this trial. Maintenance dose: the maintenance dose will be started approximately 24 hours after initiation of digoxin loading. The post-loading digoxin trough will be reviewed prior to starting maintenance dosing. Subjects on P-gp inhibitors or spironolactone, will have an additional digoxin level performed 12-hours after any dose adjustment. Once digoxin levels are stable, 24-hour blood draws will be performed.

介入なし：Arm B: No Digoxin
In the no digoxin arm, no study drug or placebo will be administered. |
