Description Market research report to assess likely demand for a test, based on a specific marker - "FGF-23", to help assess risk in cats of developing chronic kidney disease, and response to dietary interventions.
"Freedom to operate" report to identify the owners of intellectual property (patent) rights, that would govern the commercialisation of such a test.
Exploitation Route Findings indicate that there is market potential for a diagnostic company to develop a product, subject to obtaining licence rights from patent owners.

Title FGF23 as a diagnostic and monitoring tool in Veterinary Clinical Diagnostics 
Description Based on our published work and advocacy, IDEXX have licensed serum FGF23 for veterinary use and are marketing this test for managing and monitoring phosphorous overload in chronic kidney disease. (see https://www.idexx.co.uk/en-gb/veterinary/reference-laboratories/fgf-23/) . This test is now available to vets in clinical practice who diagnose chronic kidney disease (CKD) early in cats through health screening and want to know whether dietary phosphate restriction is warranted. We have advocated this approach principally because not all cats with CKD respond well to the clinical diets that are on the market for managing CKD at this early stage. FGF23 is elevated in those cats that go on to develop more severe CKD and we have demonstrated that introducing diets to cats with more severe CKD is beneficial to their survival. IDEXX cite one of our papers highlighting the predictive value of FGF23 and a recent review article where we outline why dietary phosphate (particularly in the inorganic form) is damaging to cat kidneys. Our work on CKD Bone Mineral Disorder is primarily funded by Royal Canin Ltd., part of the MARS groups of companies. We are conducting clinical trials with them to determine the benefit of clinical renal diets in early stage CKD and to assess the benefit of magnesium supplementation on cats with CKD. This area of research and development featured as one of the RVC's Impact case studies in REF2021 (see https://results2021.ref.ac.uk/impact/5afadee4-ec54-4cc7-97db-07af6907df45?page=1 ). The text redacted for publication under sources corroborating the impact (source a. from IDEXX) outlined their intention to market FGF23 as a diagnostic test.
