Exclusion Criteria

• •1. Diagnosis of Fanconi anemia.
• •2. Evidence of a clonal hematologic bone marrow disorder on cytogenetics by central review
• •3. Prior immunosuppressive therapy with cyclosporine, alemtuzumab, rabbit or horse ATG and thrombopoietin receptor (TPO-R) agonists.

• •7. Patient with liver cirrhosis.
• •8. Patients who were human immune deficiency virus (HIV), hepatitis C virus or hepatitis B surface antigen (HBsAg) positive. HCV-RNA negative patients were allowed to be enrolled.
• •9. Moribund status or concurrent hepatic, renal, cardiac, neurologic, pulmonary, infectious, or metabolic disease of such severity that it would preclude the patient's ability to consent, be compliant with study procedures, tolerate protocol therapy, or that death within 30 days is likely.
• •10. Patients with cancer who were not considered cure, were on active chemotherapeutic treatment or who took drugs with hematological effects.
• •11. Administration of an investigational drug within 30 days or 5 half-lives, whichever was longer, preceding the first dose of study treatment.
• •12. Pregnancy statements and contraception requirements:
• •Pregnancy or nursing (lactating) women Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant (or female partners of male patients), unless they were using highly effective methods of contraception during dosing and for 3 months after stopping medication.
• •13. Not able to understand the investigation nature of the study or to give informed consent.
• •14. Clinically significant ECG abnormality including cardiac arrhythmias (e. g. ventricular tachycardia) complete left bundle branch block, high grade atrioventricular block, or inability to determine the QTcF interval on the ECG.
• •15. Presence of cardiac disease, or family history of idiopathic sudden death or congenital long QT syndrome.
• •16. Risk factors for Torsades de Pointe including uncorrected hypokalemia or hypomagnesemia, or use of concomitant medication(s) with a known risk to prolong the QT interval that could not be discontinued or replaced by safe alternative medication per www.qtdrugs.org.
• •17. ECOG performance status of ≥2.
• •18. Patients under the age of 40 must be referred for consideration of allogeneic bone marrow transplantation (HSCT) if (human leukocyte antigen) HLA matching had been done and a suitable matched sibling donor was available and the patient was willing to undergo transplantation (i.e. patients who did not have a HLA match or were not medically fit, not willing or unable to undergo transplantation were considered for enrollment).
