Cardiovascular (CV) etiologies, including diabetes mellitus (DM), are the most common cause of death among chronic kidney disease (CKD) patients. This post-hoc analysis of adjudicated causes of death in patients with anemia of CKD with/without DM in the ASCEND-ND trial investigated the safety of daprodustat (Dapro), a hypoxia-inducible factor prolyl hydroxylase inhibitor, for treatment of anemia of CKD in non-dialysis patients.


ASCEND-ND (NCT02876835) was a global, randomized, open-label, phase 3 CV outcome trial. Patients received daily oral Dapro or subcutaneous darbepoetin alfa (Darbe). Outcomes were centrally adjudicated. Survival data for the intent-to-treat population was analyzed using Kaplan-Meier methods (DM vs non-DM).


Of 3872 randomized patients (DM N=2194, non-DM N=1678), baseline characteristics were broadly balanced across treatment arms, although DM patients were older, had greater body mass index and systolic blood pressure, and more CV disease/CV medication use than non-DM patients. All-cause mortality was significantly higher in DM vs non-DM patients (hazard ratio [HR]=1.87, 95% confidence interval [CI]: 1.57–2.23; Figure 1A); this association did not differ by treatment (HR=1.87 [Dapro] vs 1.86 [Darbe]; p=0.96). Infection and CV mortality each accounted for approximately 30% of deaths independent of DM status (Figure 1B).


In patients with anemia of CKD not on dialysis, the overall death rate was higher in DM patients, but cause of death was similar regardless of DM status; infection in patients with or without DM was the most frequent cause of death.
