Carocell Bio receives ethical approval for human pre-clinical testing of lead proprietary peptide in collaboration with Oxford clinical researcher

Testing anti-inflammation approach to treat burns and scarring is key step in therapeutic development and potential progression to clinical testing

GREATER MANCHESTER, UK – 17 May 2022 – Today, Carocell Bio has announced that it has received approval from the Health Research Authority (HRA) to test its lead candidate proprietary peptide JEL3108 in human burns and reconstructive surgery tissue samples. The approval, which was received alongside a favourable research ethics committee opinion, will permit ex vivo human preclinical testing at Buckinghamshire Healthcare NHS Trust. The preclinical study will test Carocell Bio’s anti-inflammation approach to treating severe burns and preventing scar formation after surgery, based upon proprietary peptides that target the body’s intracellular inflammation cascade.

The project is a collaboration with Professor Fadi Issa, Associate Professor of Burns and Plastic Surgery at the University of Oxford and Consultant Plastic Surgeon, Buckinghamshire Healthcare NHS Trust. Professor Issa is a world-leading researcher on the treatment of immune-mediated diseases including transplant rejection, with significant experience of the clinical management of burns and scars – an area of significant unmet clinical need.

So far, JEL3801’s high selectivity for mitogen-activated protein kinase (MAPK, p38-alpha) has demonstrated the capability to potentially inhibit the intracellular inflammation cascade. Its 150-fold selectivity for p38-alpha over p38-beta, and 10,000-fold over other kinases could provide a much more targeted and possibly safer approach than those currently available. In combination with a specifically tailored nanoparticle topical delivery system, the peptides could facilitate a high rate of cell penetration through the skin’s surface, rapidly delivering anti-inflammation effects where they are most required following skin damage.

Carocell Bio’s CEO, Dr Mike Davies, said:

“Receiving ethical approval for these human ex-vivo studies is an important next stage in development – getting us even closer to clinical testing – and with that, to the possibility of impacting patients’ lives. Our peptide-based approach has the potential to help treat devastating burns and also help prevent scar formation post-surgery. At Carocell Bio, we believe that an anti-inflammation approach is the most effective route by which to achieve this which is why this ex-vivo testing, with world-leading research Professor Issa, is incredibly exciting.”

Professor Fadi Issa, Chief Investigator of the project, said: “We are excited to be initiating this pre-clinical research project with the Carocell Bio team. The company’s approach to treating burns and scars addresses a current area of unmet clinical need. Scarring, from burns, surgery or other causes, can cause significant physical and mental challenges, yet has often been to-date overlooked as a medical issue in its own right. By being able to eliminate or reduce scarring soon after an operation or burn with the topical application of these first-in-class peptides, we might be able to improve the quality of life for many patients worldwide.”

As part of the study, tissue will be collected from patients who have been burnt and are in need of an operation and controlled burns in patients undergoing reconstruction surgery, and treated with lead candidate JEL3108 to investigate whether the compounds can ‘switch off’ inflammation. Importantly, a small amount of the patients’ own healthy skin graft tissue will be used as a matched negative control. The ethical approval was granted by HRA and Health and Care Research Wales (HCRW).

The company has previously demonstrated efficacy of three of its proprietary peptides in a cellular model. In 2021, it announced it had received over USD $125,000 (almost GBP £100,000) in additional funding from Innovate UK to study the effect of the peptides in burns, and received USD $314,000 (GBP £250,000) seed investment from Deepbridge Capital.
