MICA: NURTuRE - changing the landscape of renal medicine to foster a unified approach to stratified medicine

Personalised medicine has the promise of changing the way we practice medicine, and rethinking the way new drugs are developed and trialled. Our objective is bold. We wish to reshape the landscape of kidney medicine in the UK, such that building disease specific cohorts, aligned with partnering of academics, clinicians, patients, charity and industry becomes an accelerated and routine conduit to achieve personalised management for all renal conditions. We have made ground-breaking progress to now establish the infrastructure to achieve this goal, and now propose bringing together world leading academic expertise to productively understand the large amounts of data collected from these unique patient groups. The exemplar outcome of this proposal is to re-classify one of the most difficult, albeit rare conditions suffered in renal medicine, idiopathic nephrotic syndrome (INS). A secondary outcome is to make use of the infrastructure and methodologies developed, to gain insight into one of the commonest kidney scenarios, chronic kidney disease (CKD), in order to make inroads into why some patients progress faster than others, a key unanswered problem.Patients diagnosed with a rare disease are often vulnerable, inadequately cared for and poorly informed about their disease. This comes about largely because individual centres or clinicians see too few cases to gain the requisite experience for optimal management, and experience builds up too slowly. This is also a barrier to effective research, with too few patients available in one or a few centres to carry out adequately powered studies. The solution is well-managed and fully inclusive disease registries, developed on a sustainable basis. We have made a significant start to this vision, with the establishment of the UK renal rare disease registry, RADAR (www.rarerenal.org), and the development of the Steroid Resistant Nephrotic Syndrome disease group as a pilot group demonstrating the immense potential of this initiative. This project has now extended to include all patients with 'idiopathic' nephrotic syndrome (INS), at all ages. A critical development underpinning the next stage of this vision is the establishment of NURTuRE, the National Unified Renal Translational Research Enterprise. The step change involves a UK infrastructure of dedicated renal study nurses, project managers, patient groups, charities and academics, resulting in the routine collection of high quality biosamples, and deep longitudinal clinical data, potentially for any renal disease cohort. Importantly, this is based on a new model of industry-academia partnership, with industry funding the bulk of the kick-off project, with a key stake in the two pilot cohorts, INS and Chronic Kidney Disease (CKD). Governance is provided by the largest UK kidney charity, Kidney Research UK.This proposal aims to exploit the new power within these two cohorts, and in particular within INS, to stratify each patient according to detailed genetic and molecular screening of patient blood and DNA samples. This re-classification will be the first since the 1970s, and is based on ground-breaking advances in our biological understanding of Nephrotic Syndrome, based on study of the target cell of the disease in the kidney, called the podocyte. This will lead to targeted therapy towards the podocyte, to replace current non-specific toxic treatments, using new biological agents.Furthermore, the proposal will generate large new datasets in CKD coupled with innovative analytic methodologies, to demonstrate how this approach has the potential to make hitherto challenging insights into disease mechanism in a multifactorial disease state.The success of this enterprise would be the change in definition, investigation and management of INS, as well as a 'shop window' for future studies in any kidney condition, for both clinicians/academics and for industry partners, existing and future.
