Roll-over Study for Participants Who Have Completed a Previous Clinical Study With Benralizumab (Fasenra) and Benefit From Continued Treatment

The rationale of the roll-over study (ROSY) is to provide continuous access to study treatment for participants who have completed or exited a parent study and are deemed appropriate for continued benralizumab treatment, as judged by the Investigator, while monitoring long-term safety and tolerability of benralizumab.
