Approximately 102 erythropoiesis stimulating agents (ESA)-naïve participants and 204 ESA-treated participants will be enrolled and randomized respectively in a 1:1 ratio to receive roxadustat at one of 2 starting doses as below: * Low weight-based dosing: 70 milligrams (mg) 3 times a week (TIW) for body weight \<60 kilograms (kg) or 100 mg TIW for body weight ≥60 kg * Standard weight-based dosing: 100 mg TIW for body weight \<60 kg or 120 mg TIW for body weight ≥60 kg After 20 weeks of treatment, all eligible participants whose last 2 Hb levels ≥105 grams (g)/liter (L) and change in Hb over the most recent 4 weeks is \> - 10 g/L will switch to receive roxadustat for another 16 weeks to evaluate the efficacy and safety of new dosing regimens. At the end of Week 36, all participants will discontinue roxadustat and enter a 4-week Follow-up Period.
