7th January 2021 - Press Release

The CARBALIVE Consortium announces positive results of a Phase 2 equivalent trial of engineered macroporous carbons as a novel treatment for cirrhosis

  • Patients treated with orally-administered, non-absorbable engineered carbon of controlled porosity was safe, tolerable and showed trends in improvements in a range of biomarkers of systemic inflammation 

  • The mechanism of this effect is modulation of dysbiosis, gut inflammation and leaky gut that are characteristic of cirrhosis 

  • Planning for pivotal trials to support approval in Europe is now under way 


7th January, 2021 – The CARBALIVE Consortium (‘CARBALIVE’ or the ‘Consortium’) is pleased to announce positive data from the Phase 2 equivalent randomised, double-blind clinical trial of Carbalive™, a product candidate for the treatment of patients with decompensated cirrhosis. Carbalive™ is specifically designed to remove harmful bacterial toxins from the gut, reduce gut inflammation and its permeability, preventing them from leaking into the rest of the body.  

The CARBALIVE consortium is focused on developing a novel treatment for patients with advanced liver disease. It is composed of partners from across Europe, led by University College London, and includes Yaqrit, a life sciences company and the intellectual property owner of Carbalive™ and the European Foundation for the Study of Chronic Liver Failure ( among others. This academic-industrial consortium is funded by the European Union’s Horizon 2020 research and innovation programme.


The Consortium is developing and testing Carbalive™, an orally-administered, non-absorbable engineered carbon of controlled porosity. The microscopic design of the Carbalive™ beads emerged from research into the importance of gut bacteria in the inflammation that accompanies cirrhosis. The research into the effects of the leakage of bacteria and bacterial products from the gut to the rest of the body, and how to inhibit it,  was led by Professor Rajiv Jalan, Dr Jane Macnaughtan and members of the Liver Failure Group at University College London (UCL), and Yaqrit was spun off from UCL in 2014 to develop and potentially commercialise treatments including Carbalive™ for patients with advanced liver disease.


Carbalive™ has a special physical structure that adsorbs both large and small molecules in the gut. It is intended to treat patients with cirrhosis, a condition with over 100 million cases globally[1] in 2017, accounting for the mortality of about 1 million patients each year.[2] Patients with stable (compensated) cirrhosis from any cause, including alcohol, viral infection and fatty liver, can decompensate without warning, an event that usually leads to hospitalisation, is characterised pathophysiologically by systemic inflammation and carries a high risk of short-term mortality. 

The randomised controlled, double-blinded clinical trial investigated the safety and tolerability of Carbalive™, compared to placebo, over a three month treatment period in adults with stable decompensated alcohol-related cirrhosis who had been abstinent from alcohol for the previous four weeks. 

Carbalive™ was found to be safe, based on detailed clinical and biochemical assessments compared with the placebo and, was well tolerated with compliance of greater than 90%. Preliminary data from the trial also showed trends in the improvements of a wide range of biomarkers of systemic inflammation, which is especially notable because Carbalive™ is not systemically absorbed. Measures of gut-specific health also improved in Carbalive™ patients compared to those on the placebo arm. These improvements were associated with trends towards reduction in the markers of gut inflammation, less translocation (leakiness) of the gut wall and improvement of gut bacterial flora; characteristic problems associated with cirrhosis and its complications. The conclusions set forth in this announcement remain subject to finalising the remaining data analysis, the statistical and clinical study report and, therefore may change.

Professor Rajiv Jalan M.D., Professor of Hepatology at UCL, Founding Member of EASL CLIF and Project Coordinator for the CARBALIVE consortium, said, “With no specifically approved therapies for decompensated cirrhosis, there is a huge need for new treatment options. Results from this trial are very promising. The product’s safety and tolerability profile and, preliminary efficacy data continue to give us confidence that Carbalive is a promising candidate for the treatment of liver disease. Yaqrit is now planning to proceed with a pivotal trial in Europe, which could pave the way for regulatory approval in this region. I acknowledge gratefully the support of the EU H2020 grant, the huge contribution of all my collaborators and the patients who have been instrumental in the progress the Consortium has made in allowing the development of this treatment, that has the potential to save the lives of patients with cirrhosis.”

Professor Agustin Albillos M.D., of the Hospital Universitario Ramón y Cajal, Universidad de Alcalá, Spain, said: “At its heart, this world leading consortium of experienced and expert research groups within the field of liver disease has sought to find a way to address the relationship between the gut’s microbiome and the progression of liver injury to advanced stages and complications of cirrhosis. These results reported today indicate that Carbalive is having a positive impact on inflammation and therefore could prevent this progression of cirrhosis complications. On behalf of the Consortium, I’d like to extend our gratitude to the EU’s Horizon 2020 programme, which has enabled us to bring this exciting new therapy to liver disease patients, who have few treatment alternatives.”

Yaqrit, the Carbalive™ intellectual property and commercial rights holder intends to conduct a randomised placebo-controlled European pivotal trial beginning in 2021. The Company plans to pursue investigation of Carbalive™ in further indications and to engage consultants in 2021 to advise as to the potential regulatory pathway in the US.


Full results from the trial will also be submitted for peer reviewed publication in a leading scientific journal.
