Increased funding for the renewed NIHR Birmingham Biomedical Research Centre will enable continuation of major developments around inflammatory diseases and new technologies and systems

The NIHR Birmingham Biomedical Research Centre (BRC) has been awarded more than £30 million in funding from the National Institute for Health and Care Research, a major funder of global health research and training, to support world-leading research into inflammation – including the development of new diagnostic tools and treatments for those with cancer, liver and heart disease, and many more illnesses.

The centre brings together multiple BHP members – including leading NHS providers led by the University Hospitals Birmingham NHS Foundation Trust and academic institutions led by the University of Birmingham – as well as other organisations working closely with charities and businesses. Its aim is to support research into inflammation which causes or worsens many common long-term illnesses including arthritis, liver disease and cancer.

This new investment represents an almost threefold increase in funding for the NIHR Birmingham BRC and will enable researchers to focus on eight areas of illness including heart disease, women’s health, and common complications from inflammation. Researchers will also be empowered to consider new tests and biomarkers for disease, health technologies including stem cells and gene therapy, patient experiences and data science.

Professor Phil Newsome, Director of the NIHR Birmingham BRC, said: “Inflammation plays a central role in many health conditions, with millions of people in the UK alone experiencing inflammatory diseases such as arthritis and bronchitis. This significant increase in funding will enable us to provide an outstanding environment for world-leading clinical research and allow us to make a step-change in our work tackling different forms of cancer, trialling new drugs for liver disease, and dealing with antimicrobial resistance.”

Patients will benefit from the increased funding thanks to the BRC’s collaborative research that has seen nearly 1,000 clinical trials and informed UK clinical guidelines.

Researchers will look at eight themes to continue to understand and help patients manage inflammation-based diseases including cancer, arthritis, and liver disease. The investment of the NIHR funding in biomedical research will enable clinicians, researchers, patients and supporters to find new treatments such as the development of new immunotherapies, which are types of cancer treatments to support the body to fight cancer.

Professor David Adams, Director of BHP, commented: “The investment from NIHR is hugely important for researchers working across the BRC partner institutions, to continue to tackle some of the critical health themes that affect our region. The funding will allow us to deliver new therapies and diagnostic tests for a range of chronic inflammatory diseases for which we currently have few effective treatments.”

Professor Lucy Chappell, Chief Executive of the NIHR, said: “Research by NIHR Biomedical Research Centres has led to a number of ground-breaking new treatments, such as new gene therapies for haemophilia and motor neurone disease, the world-first treatment for Creutzfeldt–Jakob disease, a nose-drop vaccine for whooping cough, and the first UK-wide study into the long-term impact of COVID-19.

“This latest round of funding recognises the strength of expertise underpinning health and care research across the country and gives our nation’s best researchers more opportunities to develop innovative new treatments for patients.”

The Birmingham Biomedical Research Centre is made up of the following BHP member organisations:

  • University Hospitals Birmingham NHS Foundation Trust
  • University of Birmingham
  • Sandwell and West Birmingham NHS Trust
  • Birmingham Women’s and Children’s NHS Foundation Trust
  • Aston University

Working closely with partners:

  • Birmingham Community Healthcare NHS Foundation Trust
  • Keele University
  • University of Oxford

Urine test for bladder cancer could replace thousands of invasive procedures each year

Written by Louise Stanley on . Posted in Cancer outcomes, Clinical trials, Early diagnosis and detection.

Birmingham researchers funded by Cancer Research UK and liquid biopsy company Nonacus have developed a new urine test for bladder cancer, which could reduce the need for invasive and time-consuming procedures to diagnose the disease.

The test will use highly sensitive liquid biopsy technology developed by Nonacus in conjunction with  a panel of biomarkers developed and validated by Mr Rik Bryan and Dr Douglas Ward from the Bladder Cancer Research Centre at BHP founder-member the University of Birmingham, to detect the presence of bladder cancer by finding DNA from tumour cells present in the urine.

The biomarker panel, which consists of 443 genetic mutations that are common in bladder cancer has been validated in a deep sequencing study recently published in European Urology Oncology.

In this study, which was funded by Cancer Research UK and the Medical Research Council, the researchers used the test to analyse urine from 165 people with bladder cancer that had experienced haematuria (blood in the urine), and successfully detected the disease in 144 of them (87%).

The researchers also looked at using the test in 293 patients who had already been treated for bladder cancer and were being monitored for the cancer returning. In this setting, the test returned a higher proportion of false positive results compared to when used in the haematuria clinic (37.5% vs 15.2%), with 99 positive urine tests without a tumour being seen by cystoscopy on the same day. However, during their follow up monitoring, the patients who had those positive results had almost 3-times higher (11% vs 4%) rates of the cancer returning within 24 months indicating that the test could help detect recurrent disease before it is visible by cystoscopy (the camera inspection of the bladder). Further research is needed for the test to be used for surveillance.

Lead researcher Mr Richard Bryan said: “Even though cystoscopy is good at detecting bladder cancer, it’s invasive and time consuming for patients, so we need a better way to diagnose patients. In the future our test could be an easier way to get people with bladder cancer diagnosed faster, and could mean that tens of thousands of cystoscopies on healthy patients can be avoided each year.”

Iain Foulkes, Executive Director of Research and Innovation at Cancer Research UK said “These findings show that this urine test could help diagnose bladder cancer more easily. Early detection of cancer is key for improving patient outcomes and research like this could help identify the patients that need treatment soonest, while easing the pressures of diagnostic procedures on the NHS. We look forward to seeing how the test performs in the next clinical trial.”

The researchers are working in partnership with Nonacus, a provider of genetic testing products for precision medicine and liquid biopsy, to turn their approach into a clinical test for patients to be used within the NHS, and will start a clinical study funded by Cancer Research UK and involving over 3000 patients to evaluate just how powerful the test is at reducing the number of cystoscopies.

Each year, over 300,000 cystoscopies are carried out in England, however, around 80% of patients with haematuria who’ve had cystoscopy are found to have no cancers or abnormalities1,2.  The researchers believe that using the urine test in haematuria clinic could reduce the number of patients requiring a cystoscopy by at least 45%.

Civilians and military take part in study to improve concussion prognosis

Written by Louise Stanley on . Posted in Clinical trials.

A major UK study to identify new ways to accurately predict if patients will develop long-term complications as a consequence of concussion has been launched, led by experts at BHP founder-member the University of Birmingham and the Defence Medical Rehabilitation Centre, in collaboration with the Defence Medical Services.

With year one funded by the Ministry of Defence (£2m) and projected to run over eight years, the multi-faceted study will include a trial involving 400 civilians and 400 military personnel aged over 18 with a new diagnosis of concussion (also known as a mild traumatic brain injury or mTBI) which has resulted in them needing hospital treatment or rehabilitation.

At specific time intervals over two years, the participants will take part in nine different areas of research using a variety of medical techniques and assessments to establish if these can be used routinely by medics as ‘biomarkers’ to indicate prognosis and long term impact of concussion. Medical techniques and assessments being trialled include brain imaging and function, analysis of blood and saliva samples, and headache measures, as well as mental health, vision, balance, and cognitive performance.

mTBI is common and has been declared a major global public health problem, with 1.4 million hospital visits due to head injury annually in England and Wales – 85% of which are classified as mTBI. It is also estimated that up to 9.5% of UK military personnel with a combat role are diagnosed with mTBI annually.

The research will involve 20 University of Birmingham experts working across disciplines, including neurology, psychology, sports medicine, mathematics and academics within the University’s Centre for Human Brain Health, and will be coordinated by Birmingham Clinical Trials Unit. It will also be driven by experts at the Defence Medical Rehabilitation Centre Stanford Hall; Aston University, Imperial College London; University of Westminster; University of Nottingham; Royal Centre for Defence Medicine; and University Hospitals Coventry & Warwickshire.

Alex Sinclair, Professor of Neurology at the University of Birmingham and Chief Investigator of the project, called mTBI-Predict, explained: “Although classified as mild, and many recover, the consequences of concussion can be profound with many patients suffering long-term disability due to persistent headaches, fatigue, imbalance, memory disturbance, and poor mental health including post-traumatic stress disorder, while it can have a significant impact on the economy through loss of working hours and demand on the health system.

“Identifying those patients most at risk of these disabling consequences is not currently possible. There is therefore a pressing need to develop accurate, reproducible biomarkers of mTBI that are practical for use in a clinical setting and can predict long-term complications. Our programme of research will deliver a step change in the care of patients with mTBI, enabling a personalised medicine approach to target early intervention for those most in need but also identifying those with a good prognosis who can return rapidly to activities of daily living.”

Co-Chief Investigator, Air Vice-Marshall Rich Withnall QHS Director of Defence Healthcare, UK Ministry of Defence said: “I am delighted that the Defence Medical Services, including the Defence Medical Rehabilitation Centre at Stanford Hall, will be working hand-in-glove with class-leading civilian colleagues and the National Rehabilitation Centre Programme. I fully support this ground-breaking research which I am confident will lead to significant clinical innovation to benefit military and civilian patients, and have translational positive impact for sporting activities from grass-roots to elite levels.”

Peter McCabe, Chief Executive of Headway – the brain injury association, said: “We know that even a seemingly minor head injury can have a major impact on a person’s life – and often the lives of those closest to them. This is particularly the case if the brain injury goes undiagnosed or its effects are mistaken for other conditions. The frustration of not having an accurate diagnosis or receiving the right support can be compounded by the lack of a clear recovery pathway or timeline. We therefore welcome this study in the hope that it can advance our understanding of concussion and mTBI.”

 

New study explores unique approach to treat a rare liver disease

Written by Louise Stanley on . Posted in Clinical trials, Experimental medicine.

A UK research study looking into a new approach to treat primary sclerosing cholangitis (PSC), a rare disease where the body’s immune attacks its own liver, has been given the green light thanks to vital funding from LifeArc and the patient-led organisation PSC Support.

The FARGO trial, led by Dr Palak Trivedi at the University of Birmingham, will find out if a new treatment can slow PSC progression and improve quality of life for patients.

What is PSC?

PSC is a rare liver disease which affects around 3,600 people in the UK. People can develop the condition at any age, but most commonly those under the age of 40.

In PSC, the body’s immune system attacks the liver, causing inflammation and scarring of the bile ducts. This causes bile to stop flowing properly, and patients experience repeated infections, develop liver failure and, in some cases, cancer. In four out of five people, the body’s immune system will also attack the bowel, leading to inflammatory bowel disease (IBD) as well as liver disease. The combination of PSC and IBD can lead to around a third of all patients developing bowel cancer and patients require a colonoscopy every year to screen for it.

Currently, doctors treat PSC by managing symptoms only. We don’t fully understand what causes PSC, and there is no cure. A liver transplant is the only life-saving treatment. Although a very rare disease, PSC accounts for 1 in 10 of all liver transplants in the UK and is now the leading reason for liver transplantation in several European countries.

While it is life saving, liver transplantation is also risky and costly to the NHS. People who have had a transplant must take a cocktail of drugs to prevent their new liver being rejected. PSC can still return in around a third of people who have had a liver transplant.

Imbalance of gut microorganisms – and a new approach

We know that the microbes present in the gut of people with PSC are different to those in people without liver and bowel inflammation. This gut microbe imbalance is linked with many abnormal immune functions, which may drive development of the condition.

In the FARGO study, the research team will find out if taking stools containing natural microbes from the gut of healthy donors, refining it in a lab, and transferring it to the bowel of people with PSC, could reverse the imbalance of gut microorganisms. This treatment is called faecal microbiota transplantation, or FMT. Early research has also shown that it can treat IBD.

Bespoke clinical trial

The Birmingham team, together with teams at the Royal Free London, St Mark’s Hospital, Imperial College London, and Norfolk and Norwich University Hospitals NHS Foundation Trust, will carry out a clinical trial to test this new treatment approach. People with PSC taking part in the study will receive either FMT once a week for eight weeks, or placebo (an inactive FMT equivalent). Each group will continue to receive their usual routine standard of care for their IBD.

The teams will observe both groups for another 40 weeks. The team will then measure how successful the treatment has been in improving liver blood tests, reduce scarring of the liver, lessen the severity of their IBD, and improving symptoms and quality of life.

Dr Palak, who is leading the trial at the NIHR Birmingham Biomedical Research Centre, said: “I am delighted that LifeArc has chosen to support such a novel, bespoke and distinctive clinical trial, and to enable us to the necessary ground work needed to better understand how PSC develops and progresses.

“This study will really help us to understand which gut microbes are most important, and how this potential treatment could be scaled up to treat more people.

“Our study will lay the foundation for future work on a larger scale, with a view to making FMT available across the world.

“Should our trial show that FMT works well, PSC Support will be advocating for patients to access FMT as early as possible. We hope this means it will be making a difference to patients within five years after we’ve completed this work.”

LifeArc’s Dr Catriona Crombie said: “Our approach to funding is to work with others, to uncover the potential of promising research that could solve complex healthcare problems that patients face.”

She continued: “We’re delighted to be jointly funding this project with PSC Support, where Dr Trivedi’s team aim to reveal more information about PSC and help to translate this experimental treatment, from lab idea towards the clinic, where it could offer hope to patients with PSC.”

Martine Walmsley, Chair of Trustees at PSC Support, said: “Although we welcome clinical trials that test brand new drugs for PSC, progress is painfully slow. People with PSC don’t have the luxury of time and we must look at quicker medicine development routes.”

Diabetes: Birmingham launches five new research studies

Written by Louise Stanley on . Posted in Clinical trials, Health inequalities, Inflammation and chronic disease.

BHP founder-member the University of Birmingham has announced the launch of five new major studies aimed at improving the prevention, treatment and management of type 1 diabetes – with a particular focus on children and young adults.

The new studies include:

  • The ELSA Study: Led by Professor Parth Narendran, the ELSA Study (EarLy Surveillance for Autoimmune diabetes) will see researchers interviewing families, doctors, nurses and schools, to determine if, and how, the UK should develop a testing and monitoring programme that will identify children at risk of type 1 diabetes. The ELSA Study is being funded by the National Institute for Health Research (NIHR), and is being carried out in collaboration with Birmingham Health Partners, Birmingham Community Healthcare NHS Foundation Trust and the Department of Health and Social Care, as well as the Universities of Cardiff, Warwick, Oxford and Imperial College London.
  • Diabetes and health inequalities: Through £1.9m funding from NIHR, Professor Tim Barrett’s team will ask children and young people with diabetes and their families from poorer and/ or ethnic minority backgrounds how language issues, feelings, income, living conditions and food availability affect how they manage diabetes. They will identify new ways to make diabetes management easier and more successful, and will test these systems in trials involving NHS hospitals.
  • Immunotherapies for diabetes: The greatest barrier to the development of specific immunotherapies for type 1 diabetes is that we currently do not understand the mechanism of how immunotherapies switch off the immune response to our own proteins. A clinical study led by Professor David Wraith, and funded by $735,000 from The Leona M. and Harry B. Helmsley Charitable Trust, will be carried out in collaboration with Cardiff University. It will test a new peptide developed by the University of Birmingham, work which was also funded by the Helmsley Charitable Trust with a $610,000 grant. The new peptide has the potential to control the T-cell immune response in people who are either at risk of developing type 1 diabetes or are newly diagnosed. In this study, the team will assess the changes in immune cells from the site of injection, the draining lymph nodes and peripheral blood. This will be the first in-depth analysis of the molecular changes responsible for antigen-specific immunotherapy in type 1 diabetes.
  • Sight loss and diabetes: Two separate projects led by Dr Jose Romero Hombrebueno will explore the function of membrane-bound cell organelles, known as mitochondria, which generate most of the chemical energy needed to power the cell’s biochemical reactions. The researchers will examine the role of mitochondrial function in both the development of multiple health conditions as the consequence of type 1 diabetes, and also the role it plays in developing diabetic retinopathy – an eye condition that can cause sight loss and blindness in people who have diabetes. The latter research is being funded by Diabetes UK, while the former is being funded by the European Foundation for the Study of Diabetes.
  • Exercise and type 1 diabetes: Led by Dr Alex Wadley and funded by the Rosetrees Trust, this research will examine how a home-based exercise programme impacts autoimmunity in patients with newly diagnosed type 1 diabetes. The project will evaluate whether exercise slows the progression of type 1 diabetes by altering the number and activity of white blood cells in the circulation that have the potential to attach to, enter and degrade the pancreas. Although evidence supports a role for exercise to promote general health and wellbeing in patients with type 1 diabetes, this project aims to provide novel evidence that exercise can directly slow the progression of the disease upon diagnosis.

Parth Narendran, Professor of Diabetes Medicine at the University of Birmingham’s Institute of Immunology and Immunotherapy, said: “The UK has one of the highest incidences of type 1 diabetes in the developed world, at 25 per 100,000 per year, and type 1 diabetes is the most common form of diabetes in children. It occurs when cells that make insulin don’t work as they should, and people with the condition have to self-inject insulin for their entire lives. Studies have recently shown that some medicines can safely delay people getting type 1 diabetes. Some countries, such as the US and Australia, already have surveillance systems to identify people at risk of developing type 1 diabetes and to offer them participation in prevention trials and also to reduce their chances of developing type 1 diabetes as an unexpected emergency. The UK does not have such a system in place. Until now, nobody in the UK has explored whether parents and children would welcome such a system, and how it would work. Through ELSA we will potentially be able to change NHS healthcare policy which would result in the early detection and prevention of this condition and its associated long-term complications.”

Timothy Barrett, Professor of Paediatrics and Child Health at the University of Birmingham’s Institute of Cancer and Genomic Sciences, said: “Diabetes causes high blood sugar levels, which can lead to eye and kidney damage if the condition is not well managed. We know that better sugar control reduces this risk, however, children with diabetes from poorer and/ or ethnic minority groups, often have worse sugar control, while these complications often develop when they are young adults who are working and starting families. There is little evidence to show any previous interventions have helped in reducing health inequalities for children with diabetes in different groups. We will work with young people, their families, and diabetes clinicians to develop an action plan that families feel comfortable with and that will support them to improve their self-management.”

Professor David Wraith, Director of the University of Birmingham’s Institute of Immunology and Immunotherapy, said: “Studies have shown that immunotherapies could play a vital role in treating type 1 diabetes, and it’s essential that we can develop new drugs that could specifically target cells that cause the body’s immune response to behave the wrong way in a person with type 1 diabetes. Our project will help improve our understanding of how the human body’s immune system responds to therapies, which in turn will help the development of new treatments.”

Dr Jose Romero Hombrebueno, Hale-Rudd Lecturer in Experimental Ophthalmology at the University of Birmingham’s Institute of Inflammation and Ageing, said: “It is estimated that 224 million people will have diabetic retinopathy and 70 million will have sight-threatening diabetic retinopathy by 2040. Nearly 90-95% of patients with type 1 diabetes and 78% with type 2 diabetes are expected to develop minimal retinal damage after having diabetes for more than 15 years. Therefore it’s essential that we carry our research that will help advance our knowledge of the underlying causes and potential ways to treat or prevent vision loss in those with diabetes.”

Dr Alex Wadley, of the University of Birmingham’s School of Sport, Exercise and Rehabilitation Sciences, said: “It’s estimated that around 70% of patients with type 1 diabetes do not meet the current recommended exercise guidelines of 150 minutes per week. We are using a home-based exercise programme, which has proven highly popular and safe for individuals with type 1 diabetes, to evaluate how regular exercise impacts the immune system of newly diagnosed patients. Type 1 diabetes is a disease where the body’s own white blood cells attack the pancreas and stop insulin production, resulting in high blood sugar. Regular participation in exercise is key to supporting health and wellbeing in people with type 1 diabetes, but we don’t know how exercise directly impacts these white blood cells that do the damage. With limited therapies available for patients currently, we hope that our findings can promote the use of exercise as an important lifestyle choice for patients and impact standard treatment approaches for type 1 diabetes nationally.’’

New clinical trial aims to improve heart protection during surgery in children

Written by Louise Stanley on . Posted in Clinical trials.

A new clinical trial being led by BHP founder-member the University of Birmingham and funded by the British Heart Foundation could help improve the recovery of children who undergo life-saving heart surgery.

The £570,000 study will compare two ways of protecting the heart when children require open heart surgery to repair congenital heart defects, to find which is most effective.

Congenital heart disease is a heart defect that develops in the womb before a baby is born. Each day in the UK, around 13 babies are diagnosed with a congenital heart condition, with more diagnoses later in life.

In severe cases, and often at a young age, open heart surgery is required to repair the defect to help improve the child’s survival and quality of life. Some children require multiple operations, and recovery from open heart surgery can take several weeks or even months.

During open heart surgery, a fluid called cardioplegia is commonly used to stop the heart beating so that the surgeon can repair it safely. Although the technique is safe, cardioplegia stops the blood flow to the heart and may cause damage to the heart muscle when the blood flow is restored, which can affect the child’s recovery.

There are many different types of cardioplegia solutions available, which work in slightly different ways – and it is not currently known which fluid works best in children of different ages.

In the United States, the most commonly used solution is called del Nido cardioplegia, which was designed specifically for use in children’s heart surgery but has not previously been available in the UK.

The new trial will compare del Nido cardioplegia with St Thomas’ cardioplegia, which has been used for many years in both adults and children and is currently the standard of care in the UK.

It will involve 220 children undergoing open heart surgery at four hospitals across the UK – Birmingham Children’s Hospital, Bristol Royal Hospital for Children, Great Ormond Street Hospital and Leeds Children’s Hospital.

Half of the patients will be assigned to receive del Nido, with the other half receiving St Thomas’ cardioplegia. Researchers will then compare the two groups by assessing how well the children recover from surgery and determining the extent of any heart damage.

The study will help to reveal whether one solution is potentially more effective than the other for children during surgery.

The research will be led by Nigel Drury, Consultant in Paediatric Cardiac Surgery at BHP member Birmingham Children’s Hospital and Hunterian Professor in the Institute of Cardiovascular Sciences at the University of Birmingham.

Mr Drury, who is also a British Heart Foundation (BHF) Intermediate Fellow, said: “By improving the way in which we protect the heart during surgery, we expect that children will recover from surgery faster and with fewer complications.

“These early benefits may also lead to better long-term outcomes, with less injury and scarring to the heart muscle. As children with severe heart defects often need multiple operations, they will have the most to gain from improving how we protect the heart during each surgery.

“If our trial is successful, this will support the need for a larger, definitive study, which could have the potential to change the way children are treated around the world.”

Dr Shannon Amoils, Senior Research Advisor at the British Heart Foundation, said: “Heart defects are the most common congenital anomaly in babies born in the UK, so it’s important that we continue to refine treatments for these conditions to help improve the lives of young patients.

“This multi-centre trial, held at four leading UK children’s hospitals, will compare how well these two solutions can protect the hearts of children undergoing open heart surgery. If the study reveals important differences between the two solutions, a larger clinical trial would be needed to further investigate the findings. Ultimately, this important research could result in heart surgery becoming even safer for children.

“The BHF can only fund vital research like this thanks to the generous support of the public, in driving forward our mission to beat heartbreak forever.”

Alfie Donnelly, aged nine and from Erdington, was born with various complex congenital heart diseases and has had to undergo three open heart surgeries at Birmingham Children’s Hospital.

Mum Claire Donnelly, aged 43, said: “When Alfie was a new-born, we noticed that he wasn’t feeding well, was cold all the time and wouldn’t cry. We struggled to wake him one morning and he was making a grunting noise when he was breathing, so I rang the hospital who told us to bring him in.

“Alfie became so ill that he was put on a life support machine. After several tests and scans, we were told that Alfie’s heart condition was rare and complex and that he needed open heart surgery. We were also told that if a procedure did go ahead, it was unlikely he would survive past his first birthday. The whole situation felt so bizarre, I remember feeling frozen to the spot.

“Alfie was just one week old when he had his first operation, and he was a little fighter. He has since had two more open heart surgeries, which included replacing the damaged valve in his heart with a donor valve.

“Alfie’s recovery after surgery has been slow and he has had further complications. Following his first and second surgery, Alfie had a build up of fluid in his lungs and this required several chest drains, which meant spending further time in hospital.

“With what Alfie has been through, it has made us a solid family and we all appreciate life even more. For us as a family, the research that the BHF is funding gives us hope that children and babies with congenital heart disease, like Alfie, aren’t being forgotten. So much more is needed to raise awareness of heart defects in children.”
