Study of Roxadustat for Reducing the Incidence of Acute Kidney Injury After Coronary Artery Bypass Grafting

Roxadustat Reduces the Incidence of Acute Kidney Injury After Coronary Artery Bypass Grafting: a Multicenter, Randomized, Double-blind, Placebo-controlled Study

Acute kidney injury is a frequent complication after coronary artery bypass grafting (CABG). Roxadustat is a prolyl hydroxylase inhibitor (PHI) which can stabilize hypoxia-inducible factor (HIF) and improve the hypoxic tolerance of tissues. Roxadustat has shown effect in reducing acute kidney injury in animal studies.

This study aims to evaluate the efficacy of administration of Roxadustat before surgery in the prevention of acute kidney injury after CABG.

Acute kidney injury is a frequent complication after coronary artery bypass grafting (CABG), with a incidence of 28-38%. Renal ischemia-reperfusion injury is the main mechanism for acute kidney injury after CABG.

Roxadustat is a kind of prolyl hydroxylase inhibitor (PHI) which can stabilize hypoxia-inducible factor (HIF) and improve the hypoxic tolerance of tissues. Roxadustat has shown effect in reducing acute kidney injury in animal studies.

This study aims to evaluate the efficacy of administration of Roxadustat (before surgery) in the prevention of acute kidney injury after CABG. This is a multicenter, randomized, double-blind, placebo-controlled study.
