Patients with laboratory evidence of bone marrow failure (reticulocytes <100x10E9/L; platelets <30x10E9/L; neutrophils <500x10E6/L).
Active systemic bacterial, viral or fungal infection within 14 days prior to study drug administration
A history of recurrent invasive infections caused by encapsulated organisms, e.g. meningococcus or pneumococcus.
Major concurrent comorbidities including but not limited to severe kidney disease (e.g., dialysis), advanced cardiac disease (e.g., NYHA class IV), severe pulmonary disease (e.g., severe pulmonary) hypertension (WHO class IV)), or hepatic disease (e.g., active hepatitis) that in the opinion of the investigator precludes participant's participation in the study.
