Eligibility Criteria:
Inclusion Criteria:~* Age: At least 12 years of age inclusive, at the time of signing the informed consent. For those countries where local regulations permit enrolment of adults only, subject recruitment will be restricted to those who are \>=18 years of age.~* Asthma: A physician diagnosis of asthma for \>=2 years that meets the National Heart, Lung and Blood Institute guidelines or Global Initiative for Asthma guidelines.~* Mepolizumab treatment:~  a. Not receiving mepolizumab treatment at Visit 1. These subjects must also meet following inclusion criteria related to eosinophilic asthma, inhaled corticosteroid, controller medication and exacerbation history):~* Eosinophilic asthma: A high likelihood of eosinophilic asthma as per the required 'Continuation to Treatment'-criterion,~* Inhaled corticosteroid: A well-documented requirement for regular treatment with high dose inhaled corticosteroid (ICS) in the 12 months prior to Visit 1 with or without maintenance oral corticosteroids (OCS), for subjects \>=18 years old, ICS dose must be \>=880 micrograms (mcg)/day fluticasone propionate (FP) (ex-actuator) or equivalent daily, For ICS/long-acting-beta-2-agonist (LABA) combination preparations, the highest approved maintenance dose in the local country will meet this ICS criterion, for subjects \>=12 to \<=17 years old, ICS dose must be \>=440 mcg/day FP (ex-actuator) or equivalent daily, for ICS/LABA combination preparations, the mid-strength approved maintenance dose in the local country will meet this ICS criterion.~* Controller medication: Current treatment with an additional controller medication, besides ICS, for at least 3 months or a documented failure in the past 12 months of an additional controller medication (e.g., LABA, leukotriene receptor antagonist \[LTRA\], or theophylline) for at least 3 successive months.~* Exacerbation history: Previously confirmed history of one or more exacerbations requiring treatment with systemic corticosteroid (CS) \[intramuscular (IM), intravenous, or oral\] in the 12 months prior to Visit 1, despite the use of high-dose ICS. For subjects receiving maintenance CS, the CS treatment for an exacerbation must have been a two-fold dose increase or greater.~or, b. Receiving 100 mg SC mepolizumab administered for the treatment of severe eosinophilic asthma every 4 weeks for at least 12 weeks prior to Visit 1.~* Body weight: A minimum body weight \>=40 kilograms (kg) at Visit 1~* Gender: Male or female. A female subject is eligible to participate if she is not pregnant (as confirmed by a negative urine human chorionic gonadotrophin \[hCG)\]test), planning to become pregnant during the time of study participation (and up to 16 weeks after the last dose), not lactating, and at least one of the following conditions applies: Non-reproductive potential defined as: pre-menopausal females with documented tubal ligation or documented hysteroscopic tubal occlusion procedure with follow-up confirmation of bilateral tubal occlusion or hysterectomy or documented bilateral oophorectomy, postmenopausal female, reproductive potential and agrees to follow highly effective methods for avoiding pregnancy in females of reproductive potential from 30 days prior to the first dose of study medication and until 16 weeks after the last dose of study medication and completion of the end of study/early withdrawal visit. The investigator is responsible for ensuring that subjects understand how to properly use these methods of contraception.~* Informed consent: Capable of giving signed informed consent.~Exclusion Criteria~* Presence of a known pre-existing, clinically important lung condition other than asthma. This includes current infection, bronchiectasis, pulmonary fibrosis, bronchopulmonary aspergillosis, or diagnoses of emphysema or chronic bronchitis (chronic obstructive pulmonary disease other than asthma) or a history of lung cancer.~* Subjects with other conditions that could lead to elevated eosinophils such as Hypereosinophilic Syndromes, including Churg-Strauss Syndrome, or Eosinophilic Esophagitis. Subjects with a known, pre-existing parasitic infestation within 6 months prior to Visit 1 are also to be excluded.~* A current malignancy or previous history of cancer in remission for less than 12 months prior to screening (Subjects that had localized carcinoma of the skin which was resected for cure will not be excluded).~* A known immunodeficiency (e.g. human immunodeficiency virus - HIV), other than that explained by the use of corticosteroids taken as therapy for asthma.~* Subjects who have known, pre-existing, clinically significant cardiovascular, endocrine, autoimmune, metabolic, neurological, renal, gastrointestinal, hepatic, haematological or any other system abnormalities that are uncontrolled with standard treatment.~* Known, pre-existing, unstable liver disease (as defined by the presence of ascites, encephalopathy, coagulopathy, hypoalbuminaemia, esophageal or gastric varices or persistent jaundice), cirrhosis, and known biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones)~* QT interval corrected for heart rate by either Fridericia's or Bazett's formula QTc(F)/QTc(B) ≥450milliseconds (msec) or QTc(F)/QTc(B) ≥480 msec for subjects with Bundle Branch Block at Visit 1 confirmed by electrocardiogram (ECG).~* Subjects who have received omalizumab within 130 days of Visit 1.~* Subjects who have received any monoclonal antibody (other than Xolair) to treat inflammatory disease within 5 half-lives of Visit 1.~* Subjects who have received treatment with an investigational drug, other than mepolizumab within the past 30 days or five terminal phase half-lives of the drug whichever is longer, prior to visit 1 (this also includes investigational formulations of marketed products) or experimental anti-inflammatory drugs (non biologicals) in the past 3 months.~* Subjects who have received chemotherapy within 12 months prior to Visit 1.~* A history (or suspected history) of alcohol misuse or substance abuse within 2 years prior to Visit 1.~* Subjects with hypersensitivity to mepolizumab or to any of the excipients (sodium phosphate, citric acid, sucrose, ethylenediamine tetraacetic acid (EDTA), polysorbate 80).~* Subjects who have known evidence of lack of adherence to controller medications and/or ability to follow physician's recommendations.

Study Arms:
- Mepolizumab SC 100 mg/milliliter (mL) in Safety syringe (Type: EXPERIMENTAL): Subjects will receive 3 doses of 100 mg mepolizumab, liquid drug product in safety syringe, subcutaneously as a single injection that is self-administered in the thigh, abdomen or administered in the upper arm (by caregiver only) at 4-weekly intervals; 2 doses will be administered under observation in the clinic (at Week 0 and 8). One dose will be administered outside the clinic and without observation (within 24 hours after attending the clinic at Week 4).

Based on this trial design, predict the completion outcome and termination type (if applicable).
