A team of researchers at CÚRAM, the SFI Research Centre for Medical Devices at NUI Galway, have discovered a radically new approach to the treatment of Crohn’s disease and ulcerative colitis. 

The study, published in Advanced Science, identified a groundbreaking therapeutic strategy for restoring the lining of the intestine of patients with the condition and other inflammatory bowel diseases.

The treatment could also help prevent further inflammation, which is how the disease progresses and worsens over time. 

The NUI Galway CÚRAM researchers have designed a hyaluronan (HA) enema, which has shown significant potential in protecting against damage to the intestinal lining by decreasing inflammation and aiding in the maintenance of the health of the intestinal lining. 

Crohn's disease and ulcerative colitis, or IBD, is characterised by chronic inflammation of the gastrointestinal tract and effects over 3.2 million people in Europe.

Professor Abhay Pandit, Scientific Director of CÚRAM, said: ““The team strongly believes that the developed system can be delivered as an HA enema to act as a barrier-protecting system on the damaged colon barrier, reducing intestinal inflammation in the treatment of colonic inflammatory diseases.

“This will result in reduced inflammation and protection of the intestinal lining.”

The research represents a significant leap forward from the standard therapeutic interventions for colitis, which have focused mainly on maintaining remission levels, and do not address the root cause of the condition, especially damage to the intestinal lining and intestinal function.

Dr Niranjan Kotla, conducted the principal research of the study at CÚRAM in collaboration with Dr Venkatakrishna R Jala, from the Department of Microbiology and Immunology, James Graham Brown Cancer Centre, University of Louisville, in the US.  

Dr Yury Rochev, co-lead on the publication added: "This research demonstrates the efficacy of a unique therapeutic strategy able to induce a positive effect on damaged colonic tissue. The reduction in inflammation will be of great benefit to patients and highlights the potential use of this treatment."

Alongside the research into a specific therapeutic treatment for Crohn’s and colitis, CÚRAM researchers have also identified inflammation-specific targeted carriers for local drug delivery to inflammatory bowel disease.

The findings have been published in Biomaterials.

The study looked at the highly challenging but potentially effective practice of delivering drugs directly to inflamed intestinal sites to treat inflammatory bowel disease, particularly Crohn's and ulcerative colitis.

The research team, led by Professor Abhay Pandit and Dr Yury Rochev in collaboration with Prof Larry Egan, Professor of Clinical Pharmacology at NUI Galway,  developed strong anionic charged inflammation targeted nanocarriers (IT-NCs) loaded with an immunosuppressant model drug.  

“Our results suggest that IT-NCs have promising therapeutic potential as delivery carriers' in colitis management,” said Professor Pandit.

This research was funded by the European Union's Horizon 2020 - the EU Framework Programme for Research and Innovation.

About CÚRAM  

CÚRAM, the SFI Research Centre for Medical Devices, is developing the next generation of medical devices and training a highly-skilled workforce. Set up in 2015, CÚRAM is now a world-leading Irish Medical Device R&D Centre based out of NUI Galway. While led by the National University of Ireland Galway, CÚRAM’s partner institutes include University College Dublin, University College Cork, Trinity College Dublin, University of Limerick, Royal College of Surgeons Ireland, Dublin City University, Technological University of the Shannon and National Institute Bioprocessing Research and Training. The Centre is focused on the development of abiomedical implants, therapeutic and diagnostic devices that address the needs of patients living with chronic illness. They also partner with local small-and-medium enterprises (SMEs), and multinational medical device and pharmaceutical companies to increase employment in Ireland. The Centre has seen numerous scientific breakthroughs, as researchers focus on improving the quality of life for patients living with long-term chronic conditions such as diabetes, back pain, cardiovascular disease and stroke. Our researchers focus on engineering approaches for repair and remodelling, improved drug delivery solutions and superior medical implant designs to treat chronic diseases. CÚRAM was created because of the need for clinicians, industry and researchers to collaborate in developing medical devices which will not only create jobs but also develop a global hub for MedTech.
