Real-World Study of Enarodustat for Anemia in Non-Dialysis CKD Patients

July 28, 2026 updated by: Chen Jing, Huashan Hospital

Real-World Research on Efficacy of Enarodustat in Patients With CKD-Associated Anemia

This is a single-center, prospective real-world observational study aiming to evaluate the efficacy and safety of oral enarodustat in adult non-dialysis chronic kidney disease (ND-CKD) patients with renal anemia. A total of 90 eligible participants will be enrolled and stratified into three groups according to baseline C-reactive protein (CRP) levels: CRP ≤3 mg/L, 3<CRP ≤10 mg/L, and CRP>10 mg/L. All subjects receive routine oral enarodustat treatment with individualized dose titration, together with standard supportive care for CKD. Each participant will be followed up every 4 weeks for a total of 24 weeks. The primary objective is to compare the change in hemoglobin from baseline to week 24 across different inflammation subgroups. Secondary objectives include analyzing dynamic changes of iron metabolism indicators and documenting all adverse events during treatment. This study will explore the optimal individualized dosing strategy of enarodustat under different inflammatory and iron status.

Detailed Description

Enarodustat is an oral HIF-PHI that elevates endogenous EPO to treat CKD-related anemia. Inflammation and iron disturbance interfere with its efficacy, while real-world stratified data for Chinese non-dialysis CKD patients remain scarce.

This single-center prospective cohort will recruit 90 patients equally divided into 3 groups by baseline CRP: normal (CRP ≤3 mg/L), mild inflammation (3<CRP ≤10 mg/L), moderate inflammation (CRP>10 mg/L). All subjects start enarodustat 4 mg qd, with dose adjusted 1-8 mg every 4 weeks to keep Hb 110-130 g/L. Iron supplements will be given for iron deficiency, and routine CKD medications stay stable.

Participants attend 6 visits over 24 weeks. Blood tests are performed every 4 weeks. Extended biomarkers tested at baseline, Week12 and Week24 include CBC, reticulocyte count, folate, vitamin B12, EPO, renal function, electrolytes, iPTH, iron profiles, hepcidin and CRP. UACR, vital signs, medication records, drug dose logs and all adverse events are recorded at each visit.

Primary endpoint: Hb change from baseline to Week24. Secondary endpoints cover Hb target control rate, early Hb elevation speed, longitudinal changes of reticulocytes, renal, electrolyte, bone mineral, nutritional, iron and inflammatory markers, plus total adverse event incidence. This study explores personalized enarodustat dosing under different inflammatory, iron and metabolic backgrounds.

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

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. 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.
