- MEA115588 or MEA115575 study completion: Completion of the double-blind investigational product treatment during MEA115588 or MEA115575.
- Current Anti-Asthma Therapy: Asthma is currently being treated with a controller medication (i.e., inhaled corticosteroids \[ICS\] or other asthma controlled medication) and the subject has been on a controller medication for the past 12 weeks. Subjects will be expected to continue controller therapy for the duration of the study.

- A serum pregnancy test is required of all females at the initial Baseline Visit (Visit 1). In addition, a urine pregnancy test will be performed for all females prior to enrollment, during each scheduled study visit prior to the injection of investigational product, and during the Follow-up Visit.
Exclusion
- Hypersensitivity: Hypersensitivity reaction related to study medication during the MEA115588 or MEA115575 that led to patient withdrawal. Subjects who experienced a localized injection site reaction do not need to be excluded.
- Health Status: Clinically significant change in health status during MEA115588 or MEA115575 which in the opinion of the investigator would make the subject unsuitable for participation in this long-term study.
- Malignancy: A current malignancy or malignancy that developed during MEA115588 or MEA115575 (subjects that had localized carcinoma of the skin which was resected for cure will not be excluded). \[Note for South Korea: Korean subjects with a diagnosis of malignancy within 5 years are excluded\]
- Prior SAE: A study related SAE in MEA115588 or MEA115575 that was assessed as possibly related to study medication by the investigator.
- Pregnancy: Subjects who are pregnant or breastfeeding. Subjects should not be enrolled if they plan to become pregnant during the time of study participation.
- ECG: Baseline ECG which has a clinically significant abnormality or which shows corrected QT interval with Fridericia (QTcF) \>=450 millisecond (msec) or QTcF \>=480 msec for subjects with Bundle Branch Block.
- Smoking status: Current smokers
- Liver Function: Liver function tests that meet any of the following during one of the last treatment visits in MEA115588 or MEA115575 : alanine transaminase (ALT) \>=2 x upper limit of normal (ULN); aspartate transaminase (AST) \>=2 x ULN; alkaline phosphatase \>=2 x ULN; Bilirubin \>1.5 x ULN (isolated bilirubin \>1.5 x ULN is acceptable if bilirubin is fractionated and direct bilirubin is \<35%
- Hepatitis Status: Positive Hepatitis B Surface Antigen (HBsAg) screen at Visit 1
- ECG Over-read: Clinically significant abnormality identified during the central over-read during one of the last treatment visits in MEA115588 or MEA115575
