Subjects with a diagnosis of asthma bronchial, for which Arnuity is indicated, who are naïve to Arnuity will be included.

The active component of Arnuity Ellipta is fluticasone furoate and it is indicated for the treatment of bronchial asthma. Post-marketing investigation of ARNUITY ELLIPTA will be carried out in this analysis.

The investigator will collect the information about all AEs (e.g., a disease, symptom, abnormal laboratory value) occurring after the start of Arnuity administration, regardless of whether or not Arnuity is related to an AE.

Pneumonia will be considered as priority investigation matter for this investigation and its occurrence will be monitored throughout the study period.

The response rate is the proportion of subjects assessed as "effective". Effectiveness will be comprehensively assessed based on the course of subjective and clinical symptoms and changes in Asthma Control Test (ACT) scores, etc. from the start date of administration to the end of the observation period.

ACT is a simple 5-question tool to evaluate the progression of asthma. Investigator will record the information from the ACT completed by subjects at the start of Arnuity administration, at Month 3, Year 1 from the start of Arnuity administration, or at the time of withdrawal from/termination of administration.
