CPI Collaborates with LightOx Limited on Photonics Project to Develop Next Generation Skin and Oral Cancer Therapy

CPI is collaborating on a photonics project to advance the development of next generation cancer treatment using phototherapeutic methods.

The project, a collaboration between CPI and North East-based company, LightOx, is focused on light-based treatments to target removal of skin and oral cancer cells. CPI is supporting LightOx to develop a range of molecular tools for use in imaging, therapeutics and assay development. These unique chemical probes enable cell imaging, detection, tracking and tagging of bioactive molecules, with these tags imaged using fluorescence and Raman spectroscopy.

The probes are smaller than any other commercially available product for these applications, meaning they bypass the traditional problems associated with fluorescent probes. They provide facile delivery into the cell as well as minimal disruption to cell activity prior to light activation, fundamentally changing the way in which these therapies can be delivered to patients. The technology is also able to target therapeutic action to particular body sites using a simple delivery system that enables instant treatment and cell death of selected cells and tissues without damage to healthy cells, minimising side-effects for patients.

The collaboration between CPI and LightOx forms part of the Spotlight programme, which itself is a partnership between CPI and Durham University, funded by the European Regional Development Fund (ERDF). Providing support to SMEs in the County Durham area, Spotlight helps ambitious businesses with early stage proof-of-concept research and the scaling-up of photonics technologies to accelerate commercialisation into the healthcare sector.

CPI’s expert healthcare photonics team has supported the progression of LightOx’s molecular technology through the optical analysis of LightOx’s fluorescent drugs, allowing a greater understanding and informing product development. Complementing this analysis, Durham University helped produce a prototype controllable, calibrated, light delivery system to allow LightOx to validate their new compounds. LightOx is also now in a position where the company has attracted further investment and is in the process of developing its products for clinical applications.

The project comes shortly after the opening of CPI’s new, cutting-edge National Healthcare Photonics Centre at NETPark in Sedgefield, County Durham. The new centre will support the scale-up and commercialisation of medtech products by acting as a hub for businesses of all sizes and academic partners to work on innovative methods of diagnosing disease, imaging systems – including endoscopy – and light-based treatments.

Dr Tom Harvey, CPI’s Healthcare Photonics Team Lead said “Our new Photonics Centre at NETPark provides companies such as LightOx with access to expert people, along with facilities and equipment dedicated to the development of photonics-based products for healthcare applications.”

Dr Carrie Ambler, LightOx Chief Scientific Officer, said: “CPI provided LightOx with a first-generation light box that enabled us to select leading drug candidates to progress through the therapeutic development pipeline. Following successful selection, we now expect our lead candidates through the pre-clinical evaluation aiming for Phase 1 starting in 2020/2021. 

CPI has also provided us with guidance on the healthcare regulation landscape, and this knowledge has helped shape our company business strategies and priorities moving forward.”

Professor John Girkin, Durham University Spotlight and National Healthcare Photonics Centre lead, said: “The Spotlight project is enabling CPI and Durham University to work together to support local companies in this rapidly emerging market sector. Through this project, and the Photonics Centre, we are able to combine scientific expertise within Durham and CPI’s leading support mechanisms to help a wide range of companies reach their full potential.”

It fits perfectly for us that we’re surrounded by like-minded companies at NETPark. There are a number of highly skilled people in the area who can help us grow our business. The facilities and services offered by NETPark are first class, they make office life simple and engaging.

Stuart Wilson, - CEO, Ascarii

The proximity to the universities and the infrastructure are very important factors. Ultimately having a presence in Europe is very valuable to us and we intend to stay at NETPark for many years to come.

Dr Arnab Basu, - CEO, Kromek

Access to quality facilities was one of the main drivers for deciding to locate the business at the NETPark. We have been able to use this as a launch pad to link into support from CPI and world-class expertise from Durham University.

Steve Clements, - Managing Director, aXenic

We initially came because of the printable electronics centre but access to a highly skilled semi conductor workforce in the North East has been a key factor in us staying and growing here, as well as the value for money office space and the access to funding.

Ken Williamson, - COO, PragmatIC Printing

CPI has developed a specialist offering to support SMEs looking to develop their printable electronics applications and our partnership with Business Durham has been instrumental in attracting several SMEs to locate here in the region.

Dr Jon Helliwell, - Director of Printable Electronics, CPI

The quality of the facilities at NETPark and the attitude of staff is first class. It has a really dynamic, innovative atmosphere.

Dr Neil Loxley, - Chief executive, IBEX
