- NTDT cohort: having transfused <6 RBC units in the 24 weeks prior to the screening assessment, no regular transfusion schedule, and no transfusion for 4 weeks prior to the screening assessment.
- Subject transfusion records should be obtained within 24 weeks prior to the screening assessment, containing the date of transfusion, transfused RBC units, and pre-transfusion hemoglobin values.

- Other causes of anemia (e.g., hemolytic anemia, history of pure red blood cell aplastic anemia, myelodysplastic syndrome, or multiple myeloma)
- Presence of active infection or inflammatory disease requiring systemic anti-infective therapy, including concomitant autoimmune diseases with inflammatory symptoms (e.g. generalized erythema, ankylosing spondylitis, rheumatoid arthritis, psoriatic arthritis, dry syndrome, etc.)
- Complicated retinal neovascularization requiring treatment (diabetic proliferative retinopathy, age-related exudative macular degeneration, retinal vein occlusion, macular edema, etc.)
- Inability to take oral medications, conditions with a history of gastrectomy/bowel resection that may have an effect on the absorption of gastrointestinal medications (excluding gastric polyps or colonic polypectomy), or gastroparesis that remains symptomatic on current therapy
- Clinically significant bleeding (requiring emergency blood transfusion within 12 h or a decrease in hemoglobin ≥ 2 g/dL within one week) within 4 weeks prior to the first dose, or a tendency to bleed or risk of bleeding that has not been medically or surgically corrected
- Uncontrolled hypertension, defined as a diastolic blood pressure value >95 mmHg or a systolic blood pressure >160 mmHg on 2 or more of 3 repeated blood pressure tests (each at least 5 minutes apart) during the screening period
- Complicated congestive heart failure (New York Heart Association [NYHA] class III or higher).
- history of stroke, transient ischemic attack (TIA), myocardial infarction, thromboembolic event (deep vein thrombosis, DVT), pulmonary embolism, or pulmonary infarction within 24 weeks prior to screening evaluation
- history of significant coagulation abnormalities, or platelet count >600 x 109/L or <80 x 109/L
- History of epilepsy or any past seizures.
