Leveraging Real-World Patient Data to Support Recruitment in Diabetic Kidney Disease Studies

Practicing physicians frequently obtain laboratory assessments of kidney function in their routine management of patients with diabetes. Two tests that are commonly performed are the estimated glomerular filtration rate (eGFR) and the urinary albumin toDiabetic Kidney Disease Studies creatinine ratio (ACR). Results of these tests are often used to determine patient eligibility for clinical trials of drugs to treat patients with diabetic kidney disease (DKD).

One challenge that drug developers and clinical trialists face is in choosing eGFR and ACR criteria that support the aims of the clinical study—without hindering recruitment.

To address this issue, researchers at Covance and LabCorp queried a LabCorp database of 329,841 diabetic patients to analyze real-world data. They wanted to understand the distribution of eGFR and ACR values among diabetic patients in the United States and assess how these laboratory parameters predicted renal disease progression.
