Non-renal causes include, but are not limited to vitamin B12 or folic acid deficiency, homozygous sickle-cell disease, thalassemia of all types, other non-renal cause of anaemia such as myelodysplasia or haematological malignancies)
6. Platelet count of ≤ 50 x109/L
7. Vitamin B12 deficiency defined as total serum levels of < 181 pmol/L (246 pg/ml) 10

11. Chronic congestive heart failure (New York Heart Association class IV) or are otherwise at high risk for early withdrawal or interruption of the study (due to myocardial infarction, severe or unstable coronary artery disease, stroke, or severe liver disease) within the 12 weeks before screening or during screening
12. Active or not active malignancy (except non-melanoma skin cancer) within five years before screening
13. Planned live kidney transplantation scheduled within 52 weeks after the screening visit
14. Uncontrolled hyperparathyroidism, in the investigator's opinion
15. Uncontrolled hypothyroidism determined by the investigator that they cannot participate in the study
16. Active acute or chronic infection, or uncontrolled or symptomatic inflammatory disease (e.g., rheumatoid arthritis, systemic lupus erythematosus), or a C-reactive protein level > 15 mg/L. (Routinely screening for hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) infection is not required in this protocol. By history or current clinical evidence, patients with active acute HBV or HCV infection should be excluded. Chronic HBV/HCV infection with LFTs > 3 times of normal are excluded. Known HIV positive patients are excluded)

18. Life expectancy of less than 52 weeks
19. Planned surgery during the study period (excluding minor skin excisions)
20. Have received investigational drug(s) other than those of this study within 4 weeks prior to screening, or will receive investigational drug(s) other than those of this study during the study period
21. History or clinical evidence of cardiovascular, haematologic or hepatic (ALT, AST, bilirubin values above three times the upper limit of normal [ULN] at screening) or any physical conditions that, in the opinion of the investigator, would compromise participation in the study
22. With a cognitive or psychiatric condition rendering the subject unable to be cooperative with and complete study requirements
23. Hypersensitivity to any one of the investigational drugs
24. Subjects are, in the judgement of the investigator, otherwise inappropriate for entry into the study

26. Participation in other studies involving same investigational drug(s) (Phases 1-4) of this study within 12 weeks before screening
27. Females of childbearing potential or males who are unable/unwilling to take adequate contraceptive precautions defined by the protocol for the duration of the study and for at least 28 days after last dose of investigational product. Females have a positive pregnancy test result within 24 hours prior to study entry, is otherwise known to be pregnant, plans to become pregnant in the next 12 months or is currently breastfeeding.
