Eravacycline

Last Update: April 10, 2019.

OVERVIEW

Introduction

Eravacycline is a parenterally administered tetracycline-like antibiotic used to treat moderate-to-severe intraabdominal infections due to susceptible organisms. Eravacycline use has been associated with a low rate of serum enzyme elevations during therapy but has not been convincingly linked to instances of clinically apparent acute liver injury.

Background

Eravacycline (er" a va sye' kleen) is a parenterally administered, broad spectrum synthetic tetracycline-like antibiotic with potent activity against many gram-positive and gram-negative aerobic and anaerobic organisms including many multidrug resistant organisms. Eravacycline is similar to tigecycline both in structure and in spectrum of activity and demonstrates somewhat greater potency in vitro. Tetracycline antibiotics act by binding to bacterial ribosomes and inhibiting protein synthesis. In multiple clinical trials, intravenous eravacycline has been found to be effective in treating intraabdominal and urinary tract infections. Eravacycline was approved for use in the United States for complicated intraabdominal infections in adults in 2018 and is available as 50 mg of lyophilized powder in single dose vials for reconstitution under the brand name Xerava. The recommended dose is 1 mg per kilogram intravenously every 12 hours for total of 4 to 14 days. Oral formulations for continuation as outpatient therapy are under evaluation. Common side effects of eravacycline include gastrointestinal upset, nausea and vomiting, and infusion site reactions. Tetracyclines can cause vertigo and tinnitus, skin photosensitivity reactions, and staining of developing teeth and inhibition of bone growth in children or when taken by a pregnant mother, for which reasons eravacycline should not be used in pregnant women or children below the age of nine.

Hepatotoxicity

In preclinical trials of intravenous eravacycline, serum aminotransferase elevations were mild and no more frequent than with placebo or comparator treatment arms. There were no instances of clinically apparent liver injury that could be attributed to eravacycline. Nevertheless, other tetracycline antibiotics are well known causes of drug induced liver injury. In particular, high doses of intravenous tetracycline are known to be able to cause severe hepatic microvesicular steatosis with lactic acidosis and severe hepatic dysfunction (LASH syndrome). For this reason, intravenous tetracycline was withdrawn from use. This complication has not been reported with intravenous eravacycline, omadacycline or tigecycline. The tetracyclines have also been linked to idiosyncratic liver injury with autoimmune features that generally arise with long term use and has most commonly been associated with minocycline. This complication also has not been reported with eravacycline, omadacycline or tigecycline.

Likelihood score: E* (unproven but suspected cause of clinically apparent liver injury).

Mechanism of Injury

The mechanism by which eravacycline might cause liver injury is unknown. Eravacycline is metabolized in the liver by the microsomal cytochrome P450 system, largely via CYP 3A4. Eravacycline is susceptible to drug-drug interactions with modulators of CYP 3A4, inducers causing a decrease in eravacycline plasma levels.

Outcome and Management

Patients on intravenous eravacycline who develop serum aminotransferase elevations that rise above 5 times the upper limit of normal or are accompanied by jaundice or symptoms should have eravacycline discontinued. Whether there is cross sensitivity to hepatic injury among the various tetracyclines is not known, but switching to another class of antibiotics would be more appropriate than changing to another tetracycline-like agent in patients who develop significant hepatic injury while receiving eravacycline.
