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

December 2, 2025 updated by: Peking Union Medical College Hospital

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 80 years (Adult, Older Adult)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
