Inclusion Criteria

All Cohorts:
1. Patient has provided documented informed consent or assent (the informed consent form [ICF] must be reviewed and signed by each patient; in the case of adolescent patients, both the consent of the patient’s legal representative or legal guardian, and the patient’s assent must be obtained)
2. Age 12 to 65 years, inclusive, at time of first dose.
3. Patients, who if female and of childbearing potential, are using highly effective methods of contraception and agree not to donate ova from study start to 90 days after the last dose of study drug, and who if male are willing to use barrier methods of contraception and agree not to donate sperm, from study start to 90 days after the last dose of study drug.

Cohort A (SCD Transfusion Cohort):
4. Male or female study patient with a confirmed diagnosis of sickle cell disease
• Documentation of SCD genotype (HbSS, HbSß0-thalassemia or other sickle cell syndrome variants) may be based on history of laboratory testing or must be confirmed by laboratory testing during Screening.
5. Chronically RBC transfused for primary stroke prevention or due to previous stroke. Chronic RBC transfusion is defined as: >= 6 RBC units in the previous 24 weeks before the first dose of study treatment and no transfusion-free period for > 35 days during that period.
6. Receiving chronic RBC transfusion by straight transfusions.
7. At least 24 months of chronic monthly RBC transfusions for primary stroke prevention or treatment of primary stroke (initial completed overt clinical stroke with document infarction on brain computed tomography [CT] or magnetic resonance imaging [MRI]).
8. On iron chelation therapy for > 3 months prior to enrollment.
9. Documented adequate monthly transfusions with average HbS <= 45% (the upper limit of the established academic community standard) for the previous 12 weeks of RBC transfusions before the first dose of study treatment.

Cohort B (Thalassemia Transfusion Cohort):
10. Male or female study patients with documented diagnosis of ß-thalassemia, Hemoglobin E/ ß-thalassemia or Hemoglobin H (a-thalassemia).
11. Chronically transfused, defined as: >= 6 RBC units in the previous 24 weeks before the first dose of study treatment and no transfusion-free period for > 35 days during that period.
12. On iron chelation therapy for > 3 months prior to enrollment.

Cohort C (Thalassemia Non-transfused Cohort):
13. Male or female study patients with documented diagnosis of ß-thalassemia, Hemoglobin E/ ß-thalassemia or Hemoglobin H (a-thalassemia).
14. Hemoglobin <= 10 g/dL.

3.Clinic significant and active bacterial, fungal, parasitic, or viral infect
Patients with acute bacterial,fungal,parasitic,or viral infect. requiring systemic therapy should delay Screening/enrollment until active therapy has been completed
Patients with acute viral infections without available therapies should delay Screening/enrollment until the acute infect. has resolved
4.Known HIV positivity

Pulmonary fibrosis or pulmonary hypertension are clinically significant ie>=Grade3 NCI Common Terminology Criteria for Adverse Events(CTCAE)version 4.0(or higher)
10.Condition affecting drug absorption,such as major surgery involving stomach or small intestine(prior cholecystectomy acceptable)
11.Chronic systemic glucocorticoids <=3months(90D) prior to first dose of study treatment(physiologic replacement therapy for adrenal insufficiency is allowed).Single day glucocorticoid treatment(eg, for prevention or treatment of transfusion reactions allowed)
