Chronic Kidney Disease and Diabetes Clinical Study Group

Chronic kidney disease (CKD) describes a wide variety of kidney disorders that cause damage to the kidneys over a period of months or years. It is relatively common, affecting more than 10 per cent of adults in most countries where studies have been done.

In addition to the risk of progressive kidney damage, CKD is associated with an increased risk of diseases affecting the heart and arteries. Management is focussed on treating the specific cause of the kidney disorder as well as general measures to protect kidney function including blood pressure treatment, weight loss, exercise and stopping smoking.

Current treatments are only partially effective and research is therefore urgently needed to develop new treatments as well as methods to identify which patients are most likely to benefit from these treatments.

Who we are

We are a group of leading clinical investigators from all parts of the UK with a specific research interest in chronic kidney disease including diabetic kidney disease.

The group is jointly chaired by Indranil Dasgupta, a consultant nephrologist at Heartlands Hospital, Birmingham and Kieran McCafferty, a consultant nephrologist at Barts Health NHS Trust and NIHR Renal Speciality Lead North Thames.

We are open to all investigators with an interest in CKD and to all professional groups.

Our aims:

  • Provide a forum for researchers investigating all aspects of CKD (diabetic and non-diabetic)
  • Facilitate the development of protocols for studies in people with CKD
  • Advocate for funding of studies on CKD
  • Promote collaborative working between centres to deliver studies on CKD
  • Provide a point of contact for companies wishing to engage in CKD–related research in the UK
  • Collaborate with the UK Renal Registry to optimise use of data for research and quality improvement projects
  • Facilitate discussion with industry partners to develop and deliver cost-effective studies of interventions to improve outcomes in CKD
  • Co-operate with other CSGs to promote research in areas where there is overlap between fields.

Evidence gaps and key challenges:

  • Novel treatments to slow CKD progression. Current treatment with ACEi or ARB only partially effective
  • Improved understanding of mechanisms of action of SGLT2 inhibitors and additional trials to evaluate their use in non-diabetic CKD
  • Novel biomarkers to better stratify patients and facilitate a personalised medicine approach
    Application of genomic, proteomic and metabolomic approaches to identify novel biomarkers
  • Validated surrogate outcomes to enable shorter trials.

Key projects:


Multicentre prospective CKD cohort study in collaboration with Kidney Research UK, UK Renal Registry and five industry partners. Recruitment target of 3,000 participants from 18 centres has now been reached and patients are being invited back for their follow-up sample collection. This study will establish a biorepository of blood and urine samples with linked data that can be accessed for further research via an independent Strategic Oversight and Access Committee.
