Design of Phase III trials for diabetic nephropathy currently requires patients
at a high risk of progression defined as within three years of a hard end point
(end-stage renal disease, 40% loss of estimated glomerular filtration rate, or
death). To improve the design of these trials, we used natural history data from
the Joslin Kidney Studies of chronic kidney disease in patients with diabetes to
develop an improved criterion to identify such patients. This included a training
cohort of 279 patients with type 1 diabetes and 134 end points within three
years, and a validation cohort of 221 patients with type 2 diabetes and 88 end
points. Previous trials selected patients using clinical criteria for baseline
urinary albumin-to-creatinine ratio and estimated glomerular filtration rate.
Application of these criteria to our cohort data yielded sensitivities (detection
of patients at risk) of 70-80% and prognostic values of only 52-63%. We applied
classification and regression trees analysis to select from among all clinical
characteristics and markers the optimal prognostic criterion that divided
patients with type 1 diabetes according to risk. The optimal criterion was a
serum tumor necrosis factor receptor 1 level over 4.3 ng/ml alone or 2.9-4.3
ng/ml with an albumin-to-creatinine ratio over 1900 mg/g. Remarkably, this
criterion produced similar results in both type 1 and type 2 diabetic patients.
Overall, sensitivity and prognostic value were high (72% and 81%, respectively).
Thus, application of this criterion to enrollment in future clinical trials could
reduce the sample size required to achieve adequate statistical power for
detection of treatment benefits.
