This study is a drug use investigation program of NUCALA. The objective of this study is to collect and assess information on the safety and effectiveness of the long-term use of NUCALA SC injection in daily clinical practice in subjects with Eosinophilic Granulomatosis with Polyangiitis (EGPA). All subjects who administered NUCALA for the treatment of EGPA after its approval of indication will be included in the study. In addition, after the approval, subjects who had already received NUCALA for EGPA prior to the conclusion of the contract will also be included. Approximately 300 subjects will be included in the study. The observation period per subject is up to 96 weeks (2 years) from the start of NUCALA administration for EGPA at a maximum. If a subject has withdrawn from/terminated administration of NUCALA, it will be until the withdrawal/termination. Additionally, to consider the safety and effectiveness of NUCALA administration in subjects who had withdrawn from/terminated due to symptom improvement, 48 weeks (1 year) follow-up investigation should be conducted as much as possible. The total study duration will be approximately 3 years (2 years observation period and 1 year follow-up) from the approval of EGPA indication to the lifting of approval condition. NUCALA is a registered trademark of the GlaxoSmithKline \[GSK\] group of companies.

Number of Participants With Adverse Drug Reactions (ADRs)
ADR is defined as adverse events for which a causal relationship with the drug was not ruled out.
Time frame: Up to 96 Weeks
Response Rate Based on Global Assessment of Effectiveness
Response rate is the percentage of participants assessed as "effective" based on the course of subjective symptoms and clinical symptoms. Response rate was calculated as number of participants showing response to the NUCALA treatment divided by total number of participants on treatment\*100. Percentage values are rounded-off.
Time frame: Up to 96 Weeks
Time to EGPA Relapse
EGPA relapse was defined as conditions meeting any of the following 3 criteria in participants presenting with worsening of EGPA (newly developed symptoms or worsening of existing symptoms), and the presence or absence of relapse and the time to the first relapse were evaluated: 1. corticosteroid administration newly started or a corticosteroid dose increased; 2. immunosuppressant administration newly started or an immunosuppressant dose increased; 3. hospitalization for the treatment of EGPA. Participants were considered responder for EGPA relapse if they met with any one of the three criteria mentioned above.
Time frame: Up to 96 Weeks
