Study Arms:
- Cohort A (0.4/150, 1x/ Week) (Type: EXPERIMENTAL): Eligible participant will be administered RO0503821 (methoxy polyethylene glycol-epoetin beta \[Mircera\]) SC using a dose conversion factor of 0.4/150 microgram (mcg)/ kilogram (kg) of the previous weekly erythropoiesis stimulating agents (ESA) dose, (equal to 50% assumed equi-effective dose) once weekly up to 19 weeks. After 19 weeks of core treatment period, participants will be followed-up for two optional treatment extension periods (54 weeks each).
- Cohort B (0.4/150, 1x/ 3 Weeks) (Type: EXPERIMENTAL): Eligible participant will be administered RO0503821 SC using a dose conversion factor of 0.4/150 mcg/kg of the previous weekly ESA dose, (equal to 50% assumed equi-effective dose) once every three weeks up to 19 weeks. After 19 weeks of core treatment period, participants will be followed-up for two optional treatment extension periods (54 weeks each).
- Cohort C (0.4/150, 1x/ 4 Weeks) (Type: EXPERIMENTAL): Eligible participant will be administered RO0503821 SC using a dose conversion factor of 0.4/150 mcg/kg of the previous weekly ESA dose, (equal to 50% assumed equi-effective dose) once every four weeks up to 21 weeks. After 21 weeks of core treatment period, participants will be followed-up for two optional treatment extension periods (54 weeks each).
- Cohort D (0.8/150, 1x/ Week) (Type: EXPERIMENTAL): Eligible participant will be administered RO0503821 SC using a dose conversion factor of 0.8/150 mcg/kg of the previous weekly ESA dose, (equal to 100% assumed equi-effective dose) once weekly up to 19 weeks. After 19 weeks of core treatment period, participants will be followed-up for two optional treatment extension periods (54 weeks each).
- Cohort E (0.8/150, 1x/ 3 Weeks) (Type: EXPERIMENTAL): Eligible participant will be administered RO0503821 SC using a dose conversion factor of 0.8/150 mcg/kg of the previous weekly ESA dose, (equal to 100% assumed equi-effective dose) once every three weeks up to 19 weeks. After 19 weeks of core treatment period, participants will be followed-up for two optional treatment extension periods (54 weeks each).
- Cohort F (0.8/150, 1x/ 4 Weeks) (Type: EXPERIMENTAL): Eligible participant will be administered RO0503821 SC using a dose conversion factor of 0.8/150 mcg/kg of the previous weekly ESA dose, (equal to 100% assumed equi-effective dose) once every four weeks up to 21 weeks. After 21 weeks of core treatment period, participants will be followed-up for two optional treatment extension periods (54 weeks each).
- Cohort G (1.2/150, 1x/ Week) (Type: EXPERIMENTAL): Eligible participant will be administered RO0503821 SC using a dose conversion factor of 1.2/150 mcg/kg of the previous weekly ESA dose, (equal to 150% assumed equi-effective dose) once weekly up to 19 weeks. After 19 weeks of core treatment period, participants will be followed-up for two optional treatment extension periods (54 weeks each).
- Cohort H (1.2/150, 1x/ 3 Weeks) (Type: EXPERIMENTAL): Eligible participant will be administered RO0503821 SC using a dose conversion factor of 1.2/150 mcg/kg of the previous weekly ESA dose, (equal to 150% assumed equi-effective dose) once every three weeks up to 19 weeks. After 19 weeks of core treatment period, participants will be followed-up for two optional treatment extension periods (54 weeks each).
- Cohort I (1.2/150, 1x/ 4 Weeks) (Type: EXPERIMENTAL): Eligible participant will be administered RO0503821 SC using a dose conversion factor of 1.2/150 mcg/kg of the previous weekly ESA dose, (equal to 150% assumed equi-effective dose) once every four weeks up to 21 weeks. After 21 weeks of core treatment period, participants will be followed-up for two optional treatment extension periods (54 weeks each).
