Background

CANA slows progression of chronic kidney disease (CKD) in people with type 2 diabetes. CANA also induces a reversible acute decline in estimated glomerular filtration rate (eGFR), which is believed to be a hemodynamic effect. Predictors of the initial decline and its association with long-term eGFR trajectories and safety outcomes are unknown.

Methods

This post hoc study of CREDENCE included 4289 patients with type 2 diabetes and CKD who had eGFR measured at both baseline and week 3. Participants were categorized by percentage decline in eGFR at week 3: greater than 10% decline; between 0 and 10% decline; and no decline. Baseline characteristics associated with acute eGFR drop >10% were evaluated using logistic regression. Long-term eGFR decline and safety outcomes were estimated in each eGFR decline category by linear mixed effects models and Cox regression after adjustment for laboratory measures and medication use.

Results

More participants in the CANA (956 [45%]) versus placebo (PBO) group (450 [21%]) had an acute eGFR decline >10% (p<0.001). A >30% decline occurred infrequently (89 [4%] with CANA and 39 [2%] with PBO; p<0.001). In the CANA but not in the PBO group, older age (OR CANA 1.17, 95% CI 1.05–1.31; per 10 years) and history of heart failure (OR CANA 0.77, 0.59–0.99) were associated with a higher and lower likelihood of an acute eGFR decline >10%, respectively (both p interaction<0.05). Following the initial eGFR change, long-term eGFR trajectories were similar across eGFR decline categories (all p>0.05). Safety profiles were also similar except when the drop unusually exceeded 30%, in which case adverse events and renal related adverse events occurred more frequently. Results were consistent in subgroup analysis by baseline eGFR (30-<45, 45-<60, and 60-<90 mL/min/1.73m2).

Conclusion

Although acute eGFR declines >10% occurred in nearly half of all patients following initiation of CANA, the benefit of CANA compared with PBO was observed regardless of the acute eGFR decline and safety profiles were similar.
