Short-course Antibiotics vs Standard Course Antibiotics in Patients With Cholangitis — COBRA  

Cholangitis Clinical Trial

Official title:
Very Short-course Versus Standard Course Antibiotic Therapy in Patients With Acute ChOlangitis After Adequate Endoscopic BiliaRy drAinage

Clinical Trial Summary

The goal of this multicentre randomized controlled trial is to investigate if a very short-course of antibiotics (1 day) for cholangitis after adequate drainage is non-inferior with respect to clinical cure in comparison with a standard course of antibiotics (4 to 7 days). Secondary objectives include: - Will a one-day course of antibiotics for cholangitis after adequate drainage be non-inferior with respect to relapse of cholangitis and mortality in comparison with a standard course of antibiotics? - Will a one-day course of antibiotics for cholangitis after adequate drainage result in less adverse drug events in comparison with a standard course of antibiotics? - Will a one-day course of antibiotics for cholangitis after adequate drainage reduce length of hospital stay? - Will a one-day course of antibiotics for cholangitis after adequate drainage improve quality of life? - Will a one-day course of antibiotics for cholangitis after adequate drainage be cost-effective?

Clinical Trial Description

Acute cholangitis is an infection of the biliary tract which is managed with biliary drainage and antibiotic therapy (ABT). Currently the international Tokyo Guidelines 2018 (TG18) recommend 4 to 7 days of ABT after source control. The national SWAB guideline of 2020 suggests a course of one to 3 days after biliary drainage. There are no randomized studies to guide the duration of ABT for acute cholangitis. Our recent retrospective study in the Netherlands showed that a short course of ABT seems safe and more evidence is available showing that other bacterial infections, including abdominal and bloodstream infections, can be treated with a short antibiotic course than previously assumed. Hence, the hypothesis is that a very short-course of ABT for acute cholangitis is non-inferior to a course of 4 to 7 days after adequate biliary drainage. This study is designed as a multicenter non-inferiority randomized controlled trial. Patients will be randomly assigned to the intervention group (one day of antibiotic therapy after ERCP) or the comparator group (4 to 7 days of antibiotic therapy after ERCP). ;
