Using enarodustat to correct anemia in adults with non-dialysis chronic kidney disease
Official title: A Prospective, Open-label, Randomized, Multicenter Study on the Rational Hemoglobin Target Value in Patients With Anemia of Non-dialysis Chronic Kidney Disease Treated With Enarodustat
Run by Shanghai Zhongshan Hospital · NCT06725810 · Data updated 2026-11-12
This test gives enarodustat to adults with non-dialysis chronic kidney disease and anemia to see if aiming for a higher hemoglobin (13 g/dL) versus a lower hemoglobin (11 g/dL) improves quality of life and is safe.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 18–75 with non-dialysis chronic kidney disease (eGFR ~10–90 mL/min/1.73m2), anemia meeting the trial hemoglobin criteria, adequate iron stores (ferritin >100 µg/L or TSAT >20%), and body weight 45–100 kg who can consent and attend study visits are ideal candidates.
✕Probably not a fit
People on dialysis, those with uncontrolled hypertension or very heavy proteinuria, severe comorbid conditions, or inadequate iron stores are unlikely to benefit from participation.

What this trial studies
This is a prospective, open-label, randomized multicenter trial in China that will enroll about 1,670 adults with non-dialysis chronic kidney disease (stages 2–5) and anemia. Participants are randomized 1:1 to an enarodustat dosing strategy targeting either hemoglobin 13 g/dL or hemoglobin 11 g/dL, with dose adjustments to maintain the assigned target over 96 weeks. The main clinical outcome is change in the 36-Item Short Form Health Survey (SF-36) at week 24, and the key safety outcome is time to major adverse cardiovascular events (MACE+) over 96 weeks. The initial enarodustat dose is 4 mg once daily for all patients, with subsequent titration per protocol and hemoglobin target group.
Why it matters
Potential benefit: If successful, the trial could identify an optimal hemoglobin target when treating ND-CKD anemia with enarodustat that improves quality of life without excess cardiovascular risk.
How similar studies have gone: Other drugs in the HIF-PH inhibitor class (for example roxadustat and daprodustat) have effectively raised hemoglobin in CKD-related anemia, but cardiovascular safety and optimal hemoglobin targets remain under study.
