Plain English Summary
Background and study aims
In patients with chronic liver disease, rebleeding after a first variceal bleed (bleeding from the blood vessels in the oesophagus [food pipe] or stomach) is common, but is reduced by endoscopic therapy (band ligation) of the varices (dilated blood vessels). Initial studies have suggested that propranolol with or without isosorbide mononitrate tablets may be equally effective in reducing rebleeding and are cheaper and easier to take.
Recent data suggests that carvedilol tablets may be the best medical therapy to reduce the risk of variceal bleeding. Therefore our aim was to investigate whether oral carvedilol therapy was superior to standard endoscopic band ligation at preventing rebleeding following a first variceal bleed.
Who can participate?
We aim to recruit 152 patients, male or female, aged between 18 and 75 with a diagnosis of oesophageal variceal bleeding and cirrhosis.
What does the study involve?
Patients who are stable in hospital after a first variceal bleed will be invited to enter the study. Eligible patients who consent will be randomly allocated to receive either oral carvedilol (6.25 mg for one week, then 12.5 mg daily thereafter) or standard endoscopic band ligation of their varices. Patients will be followed up until 6 months after the last patient is allocated.
What are the possible benefits and risks of participating?
There will be no immediate direct benefit to those taking part. However, there should be benefits to future patients because the results of the study are likely to influence how we treat similar patients in the future. The risks of carvedilol therapy are the same as those of any tablet which may reduce blood pressure, including dizziness or fainting.
Where is the study run from?
This multicentre study is being run from Glasgow Royal Infirmary. Patients will be recruited in Scotland, from Glasgow Royal Infirmary (the lead coordinating centre), the Royal Infirmary of Edinburgh, Gartnavel General Hospital Glasgow and the Southern General Hospital Glasgow.
When is the study starting and how long is it expected to run for?
The recruitment started in June 2006 and will run until the estimated number of patients has been recruited, which is expected to be end of 2013.
Who is funding the study?
Greater Glasgow & Clyde Health Board (UK).

Condition
Variceal rebleeding in cirrhotic patients
Intervention
Oral carvedilol tablets versus endoscopic band ligation
Carvedilol is 6.25 mg once daily for one week and if tolerated then 12.5 mg once daily until the study is completed (6 months after the last patient is randomised)
Band ligation is done every 2-3 weeks until eradication then patient is endoscoped 6 monthly, with further bands applied as necessary.

Primary outcome measures
Variceal rebleeding is monitored when it occurs during follow-up. Patients will be followed up until 6 months after the last patient is randomised.
Secondary outcome measures
1. Mortality
2. Any upper gastointestinal bleeding is monitored when it occurs during follow-up
