Eligibility
Key inclusion criteria
104317 Inclusion criteria:

* = 12 years of age
* Has life-threatening HES as defined by the treating physician's documented view that likelihood of death is high unless the course of the disease is interrupted.
* Meets the diagnostic criteria for Hyper Eosinophilic Syndrome as defined by:

Eosinophilia >1500cells/ul for at least 6 months with evidence of symptoms and signs of organ system involvement or dysfunction that can be directly related to eosinophilia (with no evidence of parasitic, allergic or other recognized causes of eosinophilia such as connective tissues disease, malignancy) or Eosinophilia of >1500cells/ul for less than 6 months who meet the other criteria for HES accompanied by clear evidence of eosinophil tissue infiltration and with exclusion for secondary causes of eosinophilia as above.

* Compassionate use: Documented failure (lack of efficacy or a contra-indication) to at least 3 standard therapies (corticosteroids, cytotoxic agents, immunomodulatory therapy, and Imatinib mesylate) at the appropriate duration and dose
* Long-term access: Entry of subjects who participated in a previous GSK HES study to this study must be supported by the following: Subjects who received mepolizumab (if study treatment is known) in a previous GSK HES study: Documented improvement in symptoms and/or signs of HES following treatment with mepolizumab or Subjects who received mepolizumab or placebo in a previous GSK HES study: The treating physician must confirm a positive benefit/risk ratio, and the anticipated clinical benefit from mepolizumab must outweigh any potential safety or tolerability risk in this study or Subjects who participated in Study 200622 should complete the protocol required assessments for the duration of 32 weeks after randomization. Subsequently, subjects should complete the 20-week assessments in Study 205203, open-label extension (OLE) to Study 200622, prior to being considered for this protocol (MHE104317). In addition, subjects should not have had an adverse event (serious or non-serious) considered related to study treatment while participating in Study 200622 or Study 205203 which resulted in permanent withdrawal of study treatment.

Key exclusion criteria
* Subjects without HES but with other conditions associated with eosinophilic pathological process such as Churg-Strauss, Wegner's Granulomatosis, atopic disorders, hypersensitivity reactions to parasitic infections, eosinophilic gastroenteropathies, will not be eligible for this compassionate use program which is restricted to life-threatening HES.
* Female subjects of child -bearing potential who are not using an effective method of contraception:

Consistent and correct use of one of the following acceptable methods of birth control for one month prior to the start of the investigation product and 16 weeks after the last dose.

* Pregnant or lactating females
* Subjects with severe/life-threatening underlying disease unrelated to HES unrelated to HES where life expectancy is estimated to be less than 3 months.
* Subjects with a history of or current malignancy: Subjects with a history of or current lymphoma or Subjects with current malignancy or previous history of cancer in remission for less than 12 months prior to the first dose. Subjects that had localized carcinoma (i.e., basal or squamous cell) of the skin which was resected for cure will not be excluded.
* Subjects with history of serious allergic reaction (hypersensitivity/anaphylaxis) to anti-IL5 or other antibody therapy or known or suspected hypersensitivity to any component of mepolizumab, leading to treatment discontinuation
* Subjects with current drug or alcohol abuse where uncertain compliance with medication causes safety risk.
* subject currently receiving any other investigational product or other investigational intervention.

201956 Inclusion criteria:

* Subject participated in GSK-sponsored asthma clinical study with mepolizumab.
* Subject has either: completed the treatment period in the mepolizumab asthma clinical study to which they were originally enrolled or if the subject was withdrawn from study treatment prematurely during the mepolizumab asthma clinical study to which they were originally enrolled but the subject has completed the study assessments at the study visit that would have been the end of the respective treatment period.
* The treating physician requesting mepolizumab under this Long-term Access Programme considers the benefits of treatment with mepolizumab outweigh the risks for the individual subject.
* To be eligible for mepolizumab treatment under this Long-term Access Programme, females of childbearing potential (FCBP) must commit to consistent and correct use of an acceptable method of birth control, beginning with consent, for the duration of the treatment with mepolizumab and for 4 months after the last mepolizumab administration.
* The subject consents to receiving treatment with mepolizumab under this Long-term Access Programme. In the case of a paediatric subject being eligible a parent(s)/guardian will give written informed consent prior to the child's participation in the study. If applicable, the subject must be able and willing to give assent to take part in the study according to the local requirement.

201956 Exclusion criteria:

* A current malignancy or history of cancer in remission for less than 12 months (Subjects who had localized carcinoma (i.e., basal or squamous cell) of the skin which was resected for cure will not be excluded).
* Subject has other clinically significant medical conditions uncontrolled with standard-of-care therapy not associated with asthma, e.g., unstable liver disease, uncontrolled cardiovascular disease, ongoing active infectious disease requiring systemic treatment.
* Subject is pregnant or breastfeeding. Subjects should not be considered for continued treatment if they plan to become pregnant during the course of treatment with mepolizumab.
* Subject has a known allergy or intolerance to a monoclonal antibody or biologic therapy including mepolizumab.
* Subject had an adverse event (serious or non-serious) considered related to study treatment whilst participating in a clinical study with mepolizumab which resulted in permanent withdrawal of study treatment.
* Subject is receiving treatment with another biological therapy such as a monoclonal antibody therapy or intravenous (IV) immunoglobulin (Ig) therapy.
* Subjects who have received treatment with an investigational drug within the past 30 days or 5 terminal phase half-lives of the drug whichever is longer, prior to initiation of mepolizumab treatment under this Long-term Access Programme (this also includes investigational formulations of marketed products).
* Subject is currently participating in any other interventional clinical study.

112562 Inclusion criteria:

* In accordance with local procedures, written informed consent/assent can be obtained from the patient or legally authorized representative.
* = 12 years of age at the time of signing the informed consent/assent.
* Meets the diagnostic criteria for HES as defined by:

Eosinophilia >1500 cells/µl for at least 6 months with evidence of symptoms and signs of organ system involvement or dysfunction that can be directly related to eosinophilia (with no evidence of parasitic, allergic or other recognised causes of eosinophilia such as connective tissues disease, malignancy) or Eosinophilia of >1500 cells/µl for less than 6 months and meet the other criteria for HES accompanied by clear evidence of eosinophil tissue infiltration and with exclusion of secondary causes of eosinophilia as above.

- Patients meeting all three of the following criteria will be eligible: The indication, HES, is a seriously debilitating or life-threatening disease; There is no satisfactory alternative treatment: documented failure (lack of efficacy or a contra-indication) to at least 3 standard therapies (corticosteroids, cytotoxic agents, immunomodulatory therapy, and Imatinib mesylate) at the appropriate duration and dose or demonstrated clinical benefit from prior treatment with mepolizumab; and There is reason to believe that the benefit:risk ratio for mepolizumab in the indication is positive.

112562 Exclusion criteria:

* Female patients of childbearing potential who are not using an effective method of contraception:

Consistent and correct use of an acceptable method of birth control for one month prior to the start of the investigational medicine and until 16 weeks after the last dose (see Appendix 3 for a list of acceptable methods of contraception).

* Pregnant or lactating females

* Patients who have received treatment with an investigational agent (biologic or non-biologic, excluding mepolizumab) within the past 30 days or 5 drug half-lives whichever is longer, prior to the administration of mepolizumab under this protocol.
