CALIBRE will be reopening to recruitment in Autumn 2021. Watch this space for further updates.

Trial Design: A multicentre randomised controlled, open-label, self-evident two-arm trial with internal pilot.
Aim: To investigate the clinical and cost-effectiveness of carvedilol versus variceal band ligation in patients with cirrhosis and medium to large oesophageal varices that have not bled.
Sample size: 2630 – CALIBRE is largest ever Phase III trial in cirrhosis.
Funding: NIHR HTA funded - £2.3m. Sponsor is University of Birmingham.
Recruitment: Over 4 years nationally. All acute NHS trusts and health boards in UK are potentially eligible

Beta Blockers Or Placebo for Primary Prophylaxis of oesophageal varices (BOPPP)

This is a UK-wide multi-centre randomised controlled trial. It will address whether primary prophylaxis against future variceal haemorrhage with non-selective beta blockers is clinically and economically effective in patients with cirrhosis and small varices. The National Institute of Health Research Health Technology Assessment (NIHR: HTA) programme commissioned this research with funding secured of £2.3 million to consent, treat and follow up 1,200 patients at multiple hospitals across the UK. The trial is led by the Institute of Liver Sciences, Kings College Hospital and Kings College London Clinical Trials Unit. BOPPP will be one of the largest ever portal hypertension trials in this group of patients, and is currently (March 2020) being run at 24 UK-wide sites, with a further 25 sites being invited to open to recruitment over the next 6 months.

Please contact for further information and for details of how your site can participate in BOPPP.

ASEPTIC (Primary Antibiotic prophylaxis using co-trimoxazole to prevent SpontanEous bacterial PeritoniTIs in Cirrhosis)

ASEPTIC is an NIHR HTA funded multi-centre trial to examine the efficacy of primary prophylaxis using the narrow spectrum antibiotic Co-Trimoxazole in patients with cirrhosis and ascites. 

We are still looking for sites and the study will run for the next 4 years. Please contact the chief Investigator Alastair O’Brien via email a.o’ for more details.
