Leeds marks milestone in international clinical trial for Prosthetic Joint Infection treatment 

An operating theatre at Leeds Teaching Hospitals NHS Trust

A clinical trial of a new product to treat Prosthetic Joint Infection (PJI) has recruited the first three patients outside the USA. Thanks to the collaboration between Leeds Teaching Hospitals, the University of Leeds, NIHR Clinical Research Facility: Leeds, and NIHR Biomedical Research Centre: Leeds, the patients were treated within 25 days of their recruitment. 

RETAIN is a global phase 2/3 double-blind clinical trial of an investigational antimicrobial peptide, zaloganan, designed by US firm Peptilogics to treat PJI. While PJI affects about two percent of joint replacements, it can cause significant problems for patients and often requires repeated surgeries to clean out the infection and replace the artificial joint. 

The trial is testing the impact on patient outcomes of an antimicrobial peptide, zaloganan, designed to tackle the bacterial biofilm that protects infection in cases of PJI and which makes the condition difficult to treat.

Professor Hemant Pandit, Professor of Orthopaedic Surgery at the University of Leeds and Honorary Consultant Orthopaedic Surgeon at Leeds Teaching Hospitals NHS Trust, and workstream lead for surgical technology at the NIHR Biomedical Research Centre: Leeds, said: “While the vast majority of knee replacement surgeries help patients move more freely and live with less pain, prosthetic joint infection is a very serious complication that can require repeated surgeries with increased risk of mortality in the most extreme cases. The diagnosis and optimal management of PJI remains challenging to surgeons, and the condition often leaves behind permanent and life-changing effects that negatively impact the patient’s limb function and overall quality of life.” 

Mr Jeya Palan, Consultant Orthopaedic Surgeon and Honorary Senior Clinical Lecturer at the University of Leeds, and co-investigator on the RETAIN trial, said: “PJI can be clinically challenging and can require multiple procedures and have unpredictable outcomes. Finding new clinical practices and options for successful treatment of this serious condition is vital to improving the outcome for patients.” 

Led by Investigators, Professor Pandit and Mr Palan, Leeds Teaching Hospitals is one of 15 sites in the UK taking part in the RETAIN trial.  

Peptilogics is a clinical stage biotech company dedicated to curing and preventing medical device-related infections (MDRI). More information about the RETAIN trial can be found on the Peptilogics website.

Leeds first to dose patients in pioneering cell therapy study for autoimmune diseases

Leeds Teaching Hospitals NHS Trust has marked an important milestone in the development of a potential new treatment for people living with difficult-to-treat autoimmune diseases, after the first patient was treated in the CHILL Phase 1/2 clinical study.

The multi-national study, delivered in Leeds by the National Institute for Health and Care Research (NIHR) Clinical Research Facility: Leeds, is evaluating QEL-005, an investigational CD19 B-cell activated engineered regulatory T cell therapy developed by Quell Therapeutics for people with difficult-to-treat rheumatoid arthritis and systemic sclerosis.

Almost half a million people in the UK have rheumatoid arthritis, and an estimated 19,000 have systemic sclerosis and this study is exploring a potential new one-time treatment for these conditions.  It involves a new type of ‘cell therapy’ that uses a patient’s own immune cells – called T-regulatory cells or Treg cells – which are collected from the blood, engineered and enhanced in the lab, and then returned to the patient.  Regulatory T cells (Tregs) are specialized immune cells that keep the immune system in balance, calming excessive responses and helping prevent tissue damage. 

The first participant in the CHILL study received treatment at Leeds Teaching Hospitals, making the Trust the first site worldwide to treat a patient in the trial. Two further patients have since been treated at Oxford University Hospitals NHS Foundation Trust, completing the study’s first dose cohort.  Quell Therapeutics has now announced that the study has progressed to its second planned dose cohort following a positive safety review.

The CHILL study is recruiting participants across seven sites in the UK and a further four sites in Germany and Spain.  Led in Leeds by Principal Investigator, Professor Francesco Del Galdo and delivered by NIHR Clinical Research Facility: Leeds in close collaboration with clinicians in haematology, including Dr Jonny Carmichael, and rheumatology experts, the trial brings together a multidisciplinary team of research and clinical experts from across the Trust and draws of the expertise and research infrastructure of the NIHR Biomedical Research Centre: Leeds, which supports pioneering research into connective tissue disease and autoinflammatory diseases.

Prof Francesco Del Galdo, Principal Investigator at Leeds Teaching Hospitals NHS Trust, said “We were thrilled to see the first CHILL patient globally receive this new intervention at Leeds Teaching Hospitals. Patient safety was central to our preparations, with the multidisciplinary team working closely together to support and monitor the patient throughout. The team worked together admirably and it was rewarding to see the patient able to return home the following day after dosing.”

Professor Chris Twelves, Director of the NIHR Clinical Research Facility: Leeds, said:  “At Leeds Teaching Hospitals, we have extensive experience delivering early-phase advanced therapy trials safely and effectively, especially for people with blood cancers. The CHILL study is the first time we have brought together specialist teams across the Trust and colleagues at the University of Leeds to deliver this type of advanced therapy for autoimmune disease. We’re delighted to be the first site to safely recruit and commence treatment to the first patient within two weeks of the trial opening.  This has been possible thanks to close collaboration and commitment of our specialist clinical and research teams working together.  By exploring whether these innovative treatments are safe and effective in conditions that are difficult to treat, we hope to pave the way for new treatments for patients in the future.”

Dr Jonny Carmichael, consultant haematology at Leeds Teaching Hospitals NHS Trust commented:  “In advanced therapy such as this, collaboration is essential. By bringing together the rheumatology, haematology and NIHR CRF: Leeds teams from Leeds Teaching Hospitals NHS Trust and the University of Leeds, we brought together the expertise to identify suitable participants, navigate the complexities of trial delivery and deliver high-quality innovative care for our patients, ensuring we deliver research safely and efficiently.”

The trial is part of Leeds Teaching Hospitals’ growing portfolio of advanced therapy clinical research and reflects the Trust’s commitment to bringing innovative treatments to patients through research.

If successful, QEL-005 could offer a new transformational treatment approach for people living with complex autoimmune diseases where existing therapies have not provided sufficient benefit.  Initial clinical data from the study is expected in 2027.

The CHILL study is delivered by NIHR Clinical Research Facility: Leeds at its state-of the-art clinical research facility at St James University Hospital.

The conference provided an excellent opportunity for the Leeds team to network, share best practice and bring back new ideas that will help further strengthen research delivery for patients across Leeds and the wider region.

Our impact: Personalised pacemaker therapy- better outcomes for patients and the NHS

Pacemakers are life-changing devices that help people with heart disease live longer and improve their quality of life. However, despite major advances in technology, many pacemakers are still left on standard factory settings rather than being tailored to the individual needs of patients. Researchers at the NIHR Clinical Research Facility (CRF) Leeds have been leading pioneering work to show how a more personalised approach to pacemaker care can improve patient outcomes, reduce hospital admissions and deliver better value for the NHS. Through a series of NIHR-supported studies, the team has helped change the way pacemaker patients are cared for locally, nationally and internationally.

Our Goal

More than 300,000 people in the UK live with a pacemaker, with around 36,000 new devices implanted every year. Researchers wanted to better understand whether personalising pacemaker settings and combining device expertise with heart failure care could improve patients’ health and quality of life. The team also recognised that symptoms such as breathlessness and tiredness in people with pacemakers are often wrongly attributed to ageing or existing heart disease, meaning heart failure can sometimes go undiagnosed and untreated.

Our Approach

Through a series of NIHR-supported clinical trials led from the NIHR Leeds CRF, researchers explored how personalised pacemaker programming and joined-up care could improve outcomes for people living with pacemakers.

The research showed that carefully adjusting pacemaker settings to suit each individual patient could:

  • Improve heart function
  • Reduce unnecessary pacing of the heart
  • Extend pacemaker battery life
  • Reduce the need for replacement surgery
  • Improve exercise capacity and quality of life

One major study involving 1,800 patients across West Yorkshire found that around one-third of people with pacemakers had previously undiagnosed heart failure.

In response, the team developed a new multidisciplinary Combined Heart Failure and Device Clinic at Leeds Teaching Hospitals NHS Trust, bringing together experts in pacemakers and heart failure treatment in one service.

The clinic is staffed by highly trained cardiac physiologists and nurses and now supports more than 300 patients each year.

Real World Impact

The work also helped develop a highly skilled and diverse research workforce, including NIHR-funded clinical researchers, cardiac physiologists and clinicians.

The research has already changed care for patients in Leeds and is influencing practice internationally.

The personalised approach developed through the NIHR Leeds CRF has now been embedded into routine NHS care at Leeds Teaching Hospitals NHS Trust through the Combined Heart Failure and Device Clinic.

Patients are receiving more tailored treatment, helping reduce hospital admissions and improving long-term outcomes.

The work has also contributed to international heart failure and pacemaker guidelines in Canada, America and Europe, helping shape care for people with pacemakers around the world.

Importantly, the research demonstrates how personalised care can improve outcomes while also reducing pressure on the NHS by preventing complications and avoiding unnecessary procedures.

What’s Next

Researchers at NIHR Leeds CRF continue to lead new studies exploring how personalised pacemaker programming can further improve care for people with heart disease.

Upcoming research includes:

  • Exploring new pacemaker lead positions and their effect on heart function
  • Developing simpler ways to personalise heart-rate settings
  • Expanding studies across multiple NHS centres
  • Investigating how personalised programming could benefit people with less severe heart failure

The team is also continuing work to increase awareness and education around personalised pacemaker care through international guideline groups, professional societies and training programmes.

This work would not have been possible without the support of NIHR infrastructure at the NIHR Leeds CRF, helping turn research into real improvements for patients, healthcare services and society.

Advanced Therapies at the NIHR Leeds Clinical Research Facility (CRF)

A picture of Professor Chris Twelves.

The NIHR Leeds Clinical Research Facility is helping to shape the future of healthcare. In this blog post, Prof Chris Twelves, Clinical Director at the CRF, outlines what advanced therapies are, why they matter, and how the CRF is supporting their safe and effective development for patients.

What are Advanced Therapies?

Advanced therapies or Advanced Therapies Medicinal Products (ATMPs) are umbrella terms describing treatments that work at the level of cells, tissues, or genetic material. These therapies can offer long-lasting benefits and in some cases, the potential for cure. They are already showing important benefits in people with blood cancers, but are now reaching into other areas.

“Advanced therapies represent some of the most innovative areas of modern medicine. They aim to repair, replace, or restore biological function in ways that were previously impossible. At the CRF we are supporting the development and delivery of these cutting-edge approaches to improve patient outcomes.”

Advanced therapies include:

  • Cell therapies: using living cells to prevent, treat, or cure disease
  • Gene therapies: introducing or modifying genes to address underlying causes of illness
  • Tissue-engineered therapies: using engineered tissues to repair or replace damaged structures
  • Combined or next-generation approaches: including engineered immune cells, cancer-targeting viruses, and virus-based vaccine platforms

These approaches are increasingly used to treat cancers, inherited diseases, immune disorders and other hard-to-treat conditions.

Advanced Therapy research

The CRF supports early-phase clinical trials involving advanced therapies and ATMPs. Working with colleagues, our specialist teams provide the facilities, governance and expertise to support safe delivery of complex studies.

We support ATMP trials including those involving CAR-T cell therapies and oncolytic viruses.

Extending the impact and reach of CAR-T cell therapies

In haematology, Dr Frances Seymour is leading clinical trials of CAR-T cells in multiple myeloma and Dr Jonathan Carmichael is working closely with Professor Francesco Del Galdo and the rheumatology team investigating novel immunotherapies in treating autoimmune diseases. This work is further strengthened by Hannah Newman, Lead Nurse for the St James’s University Hospital CRF, who brings extensive experience in haematology clinical trials.

Leading centre for oncolytic virus research

Over many years Leeds has played a major role in advancing oncolytic virus therapy. In trials we have given oncolytic viruses directly into tumours or intravenously, in patients with a range of different cancers and the virus given either alone or in combination with other ant-cancer treatments. Working with Prof Adel Samson, clinical and scientific partners, and commercial sponsors the CRF has supported studies that have helped shape the field.

“Key achievements include demonstrating that oncolytic viruses can be delivered intravenously, showing benefits when combined with immunotherapies and supporting studies that have produced durable tumour responses in melanoma and liver cancer.”

Our commitment

“Advanced therapies offer new hope for people with conditions that are difficult to treat. At the NIHR Leeds CRF, we are committed to accelerating the safe development of these life-changing innovations.”

The event showcased a range of ongoing research in Leeds, covering prostate cancer, knee replacement, early detection of lung cancer, and heart health. Alongside these presentations, attendees also had the opportunity to take part in hands-on activities, including an ECHO heart scan demonstration (pictured above), which helped people better understand how research links to real clinical practice.

Contributors, Graham Holland and Imtiaz Chaudary, reflected on their own involvement in research and highlighted the importance of inclusive research.

Attendees also took part in group discussions that explored ways to strengthen engagement, widen participation among under-represented communities, and shape future research priorities.

The conversations touched on topics such as including more community-based sessions, improved multilingual materials, better use of digital and media channels, engaging people at cultural events and public spaces, providing appropriate language support, involving healthcare teams, and offering suitable incentives. and generated suggestions that will inform future initiatives.

Feedback from participants indicated that the event provided a valuable opportunity to ask questions, share experiences, and think about how research and communities can work better together.

One attendee described the day as “Well run, well attended, interactive and informative”, while another said it “was useful and made me willing to engage in research and share the opportunities.”

The organisers plan to use insights from PPI Community Connect 2025 to guide ongoing work on improving patient and public involvement.
