Title: MEA115666: A Multi-centre, Open-label, Long Term Safety Study of Mepolizumab in Asthmatic Subjects Who Participated in the MEA112997 Trial
Brief Summary: This is a multi-centre, open-label long term safety study of 100 milligrams (mg) mepolizumab administered subcutaneously (SC) in addition to standard of care in subjects who participated in the MEA112997 study. At each clinic visit, adverse events will be assessed and exacerbations will also be reviewed.


Options:
A: Inclusion Criteria:

1. Written informed consent for study participation must be obtained prior to any study related procedures being performed (local regulations are to be followed in determining the assent/consent requirements for children and parent\[s\]/guardian\[s\]) and according to international guidelines and/or applicable European Union guidelines.
2. Female and Male aged 12 to 75 years inclusively, at the time of visit 1. For those patients, who are 17 on the day of Visit 1 but will turn 18 after this day, will be considered an adolescent for the purposes of this trial.
3. History of physician-diagnosed asthma requiring treatment with medium-to-high dose ICS (\>250μg fluticasone dry powder formulation equivalents total daily dose) and a LABA, for at least 12 months prior to Visit 1
4. Documented treatment with ICS and LABA for at least 3 months prior to Visit 1 with or without oral corticosteroids and additional asthma controllers.

   * For subjects 18 years of age and older, the ICS dose must be \>500 mcg/day fluticasone propionate dry powder formulation or equivalent daily.
   * For subjects ages 12-17, the ICS dose must be ≥500 mcg /day fluticasone propionate dry powder formulation or equivalent daily.

Exclusion criteria:

1. Clinically important pulmonary disease other than asthma (e.g. active lung infection, COPD, bronchiectasis, pulmonary fibrosis, cystic fibrosis, hypoventilation syndrome associated with obesity, lung cancer, alpha 1 anti-trypsin deficiency, and primary ciliary dyskinesia) or ever been diagnosed with pulmonary or systemic disease, other than asthma, that are associated with elevated peripheral eosinophil counts (e.g. allergic bronchopulmonary aspergillosis/mycosis, Churg- Strauss syndrome, hypereosinophilic syndrome)
2. Any disorder, including, but not limited to, cardiovascular, gastrointestinal, hepatic, renal, neurological, musculoskeletal, infectious, endocrine, metabolic, haematological, psychiatric, or major physical impairment that is not stable in the opinion of the Investigator and could:

   * Affect the safety of the patient throughout the study
   * Influence the findings of the studies or their interpretations
   * Impede the patient's ability to complete the entire duration of study
3. Acute upper or lower respiratory infections requiring antibiotics or antiviral medication within 30 days prior to the date informed consent is obtained or during the screening/run-in period
4. Any clinically significant abnormal findings in physical examination, vital signs, haematology, clinical chemistry, or urinalysis during screening/run-in period, which in the opinion of the Investigator, may put the patient at risk because of his/her participation in the study, or may influence the results of the study, or the patient's ability to complete entire duration of the study
B: Inclusion Criteria:

* Informed Consent.
* MEA112997 Study Participation: Received at least 2 doses of double-blind investigational product during the MEA112997 trial.
* MEA112997 Treatment Assignment: If the subject received mepolizumab, they must have had a positive risk: benefit ratio.
* Currently being treated with a controller medication and the subject has been on a controller medication for the past 12 weeks.
* Male or Eligible Female Subjects. To be eligible for entry into the study, females of childbearing potential must commit to consistent and correct use of an acceptable method of birth control for the duration of the trial and for 4 months after the last study drug administration.

Exclusion Criteria:

* Hypersensitivity related to mepolizumab.
* Clinically significant change in health status since completing participation in the MEA112997 trial.
* A current malignancy or previous history of cancer in remission for less than 12 months prior to screening.
* For those subjects who had a SAE in MEA112997 that was assessed as possibly related to mepolizumab by the investigator.
* Subjects who are pregnant or breastfeeding. Subjects should not be enrolled if they plan to become pregnant during the time of study participation.
* Screening ECG which has a clinically significant abnormality.
* Received Xolair (omalizumab) within the past 130 days.
* Participated in a clinical trial within the past 30 days or have received investigational medication within five terminal half-lives of Screen Visit, whichever is longer.
* Current smokers.
C: * INCLUSION CRITERIA:

To be eligible to participate in this study, an individual must meet all of the following criteria:

1. Stated willingness to comply with all study procedures and availability for the duration of the study
2. Male or female, aged 1-100
3. Ability of subject (or Legally Authorized Representative (LAR)) to understand and sign a written informed consent document

   Eosinophilic Patients only:
4. Documented peripheral blood count \>1500/mm3, tissue eosinophilia (abnormal accumulation of eosinophils in the skin or other body tissues) or suspected eosinophilic end organ involvement
5. Primary (non-NIH) physician for routine medical care

   Relatives only:
6. Extended family member of an eosinophilic participant on this protocol

EXCLUSION CRITERIA:

An individual who meets any of the following criteria will be excluded from participation in this study:

   Relatives only:
2. Females must not be pregnant
D: Inclusion Criteria:

* Physician diagnosis of asthma for greater than or equal to 3 years and a diagnosis of severe persistent asthma forgreater than or equal to 1 year prior to screening
