Patients with active tuberculosis, latent tuberculosis, or nontuberculous mycobacterial infection at screening; Notes: * Unless treatment records clearly documented by a specialist demonstrate that the patients have been adequately treated and may begin treatment with biological product (based on the medical judgment by the investigator and/or infectious disease specialist); * If needed, T-spot tests may be used to assist diagnosis of suspected tuberculosis. 15. Subjects with white blood cell count and neutrophil count below the lower limit of normal. 16. Female subjects with hemoglobin values less than 110 g/L or male subjects less than 120 g/L. 17.
