Angiotensin 2 for Hepatorenal Syndrome — ANTHEM  

Cirrhosis Clinical Trial

Official title: Angiotensin 2 as a Novel Treatment for Hepatorenal Syndrome

Status Withdrawn

Clinical Trial Summary

Hepatorenal syndrome (HRS) is a disease in which patients with cirrhosis (end stage liver failure) develop secondary kidney injury and failure. The current treatment available in the United States is a combination of octreotide and midodrine, which are meant to decrease the release of those hormones and raise the blood pressure, respectively, which would increase blood flow to the kidneys. Angiotensin 2 (Ang2) is a new vasopressor drug that was approved by the FDA in December 2017 for patients with low blood pressure and has been shown to have similar effects to octreotide and midodrine.

This study will investigate whether Ang2 reverses HRS among patients admitted to the intensive care unit (ICU) at Ronald Reagan Medical Center. Our study population will be patients with HRS who are already or will be admitted to the ICU. HRS will be defined by new internationally accepted guidelines published by the International Club of Ascites. All patients who are consented will undergo an Ang2 response trial, where low-dose Ang2 will be administered for 4 hours to see how the patients respond. This will help us characterize the nature of the patients' kidney failure for later analysis. Patients will then be randomized into the control group or the study group. Patients in the control group will receive octreotide (a subcutaneous injection) and midodrine (an oral drug). Patients in the study group will continue receiving intravenous infusion of Ang2. Patients in both groups will also receive albumin, a protein found commonly in human blood. Treatment will continue in both groups for four days, until complete reversal of HRS, dialysis, or death.

Our primary outcome will be rate of reversal of HRS, defined as improvement in kidney function.
