About Us

The PBC Foundation is the only UK organisation exclusively dedicated to providing support and information to those affected by PBC

Medical Research

Medical Research

The Foundation is very proud of its record in funding and facilitating research on PBC. It has uniquely funded a number of projects and started the ball rolling on others.

Current research opportunities

The KLEAR Clinical Research Study

The KLEAR Clinical Research Study needs your help to determine whether an investigational drug called CR845 works to reduce itching in adults who have primary biliary cholangitis (PBC).

OACS-1 Trial led by Professor David Jones OBE 

We are delighted to share details of a new UK based trial, "Obeticholic Acid for the Amelioration of Cognitive Symptoms trial - 1" designed to find out whether taking a drug known as Obeticholic Acid has any impact on the symptoms of "brain fog", poor memory, concentration or fatigue in patients with PBC.

For more information, please click here.

The RESPONSE study

The RESPONSE study is enrolling patients who have been using ursodeoxycholic acid (UDCA or ursodiol) but have not achieved the recommended treatment goal or who developed troublesome side effects from UDCA that prevent them from continuing to take this treatment. The study will evaluate if seladelpar can improve PBC-related blood laboratory tests and can improve symptoms of PBC, such as itching.

Current surveys

PBC and Itch 2022 Survey

Participate in our new PBC and Itch 2022 survey on our PBC Foundation App and be involved in our latest campaign to improve the lives of everyone with PBC.. For more information please click here

Clinical Trial Preferences Survey

New Patient Survey about clinical trial preferences for tracking symptoms. We are working closely with research teams to develop new treatments for PBC symptoms and are seeking your important input. For more information please click here

Patient Experience Survey available on the PBC Foundation App

The PBC Foundation is working hard on your behalf to improve the treatment and care you receive. To this end, it is vital that we understand the patient experience of the PBC clinical journey to identify your unmet needs. For more information please click here. 

 

Previous research

One of the most successful in funded studies was "PBC 40" project, in conjunction with the University of Newcastle and Liverpool. This produced a 40 questions tool that measures the quality of life of PBC in a scientifically valid way.

We also were fortunate enough to be bequeathed a sum of money that should be used to finance a PBC research project. This project is in progress at Norwich Hospital and the University of Norfolk and is looking at what happens with biliary cells when they become inflamed and injured, as occurs in PBC.

The study most successful we have been involved in is the original PBC Study Genetics based in Addenbrookes Hospital in Cambridge. This study used DNA samples from thousands of patients across the UK to help identify the genetic reasons why someone develops PBC. The success of this study led to a broader study that is called UK-PBC (www.uk-pbc.com). These are groups around the UK (Newcastle, Birmingham, Cambridge, and Imperial College in London among many) that work together to combat the lack of new treatments for patients. Within this involvement patient study is fundamental, and includes opportunities to further genetic collection, studies bear why not work for everyone, and most importantly, in many respects, opportunities to participate in new drug trials for PBC (including symptoms ). All who participated in the original study of genetics will be notified about it, and new patients are encouraged to participate if they have not been invited by their doctors to do so. Patients can ask their own doctor about it, or contact direct UK-PBC (01223 769 088).

The PBC Foundation was also involved in educating not only patients but also doctors. An example from 2014 is a conference where doctors learn about autoimmune liver disease patients and ear specialists not only clinical.

The exciting thing about research is how it spans so much, and how anyone can participate, either by answering a few questions about your symptoms, all the way to trying new drugs, if necessary.

Grant/Award

Investigation into the Pathogenesis of Primary Biliary Cirrhosis

Professor James Neuberger, Queen Elizabeth Hospital, Birmingham

October 1997

September 2000

£75,000

In conjunction with British Liver Trust

These studies have provided a robust way of isolating and maintaining in culture human biliary epithelial cells (the main site of damage in PBC) so that laboratory studies can be carried out to investigate further the relationship between AMA and PBC.

Establishment of PBC Database

Professor Oliver James, Freeman Hospital, Newcastle

1997

1998

£10,000

Raised by Members of the PBC Foundation

This allowed the creation of a national database. As well as allowing the formation of a database that will provide more information about people in the UK with PBC but also showed that doctors can work together effectively.

Improving the Assessment of Outcome in Primary Biliary Cirrhosis

Development of the Health-Related Quality of Life Measure, namely the PBC 40

Newly Discovered Microbial Mimics as Triggers of PBC

Professor Diego Vergani, Royal Free and University College Medical School, University College London

March 2000

August 2001

£5,000

Bequeathed by Edgar Ernest of Dorset

These studies looked at whether microbes (such as some bacteria) can confuse the body’s immune system so that instead of reacting with microbes, the immune system attacks similar targets in the liver. They showed that there may be cross-reaction with a number of bacteria, which could trigger PBC in some individuals.

The Role of the Pregnane X receptor in Primary Biliary Cirrhosis Pathogenesis

Dr Matthew C Wright, University of Aberdeen

October 2003

October 2006

£75,000

Raised by Members of the PBC Foundation

This study looked at a protein called PXR and studied whether activation of this inhibits inflammation in the liver.   Since PXR activation promotes hepatocyte growth and is also anti-fibrogenic, the PXR may be an excellent drug target for the treatment of chronic inflammatory liver disease and PBC.

Raised by Members of the PBC Foundation

The PBC Genetics Study was a UK-wide initiative to establish the UKPBC Research Cohort, a cohort of more than 4000 PBC patients for population-level research, including large-scale genetic studies. DNA samples obtained from the UKPBC Research Cohort were used for a genome-wide association study of PBC in 2010 and an iCHIP study of PBC in 2012. The PBC Genetics Study has now evolved into the UKPBC Project, which is broader in its ambition to elucidate the biological origins of PBC.
