Long-term Access Program (LAP) of Mepolizumab for Subjects Who Participated in Study MEA115921

February 14, 2024 updated by: GlaxoSmithKline

Mepolizumab Long-term Access Programme for Subjects Who Participated in Study MEA115921 (Placebo-controlled Study of Mepolizumab in the Treatment of Eosinophilic Granulomatosis With Polyangiitis in Subjects Receiving Standard-of-care Therapy)

Eosinophilic Granulomatosis with Polyangiitis (EGPA), also referred to as Churg-Strauss syndrome, is a rare hyper-eosinophilic syndrome. Eosinophilia is central to the pathophysiology of EGPA and interleukin-5 (IL-5) is a key cytokine regulating the life-cycle of the eosinophil. Neutralization of IL-5 with mepolizumab, an anti-IL5 monoclonal antibody, therefore offers a potential therapeutic option for EGPA. The objective of study MEA115921 was to investigate the efficacy and safety of mepolizumab compared with placebo wherein the subjects were randomized to receive either: 300 milligram (mg) mepolizumab or Placebo subcutaneous (SC) injection every 4 weeks in addition to their background standard-of-care therapy. Subjects were treated for a period of 52 weeks and then followed up for a further 8 weeks to study completion at Week 60. This is a LAP to support provision of open-label mepolizumab on an individual basis to eligible subjects who participated in clinical study MEA115921 and who require a dose of prednisolone (or equivalent) of >=5 milligrams per day (mg/day) for adequate control of their EGPA. Eligible subjects can initiate mepolizumab under this LAP within a 6-month period starting from completion of study MEA115921 (that is, at Week 60) or, in case of premature discontinuation from study MEA115921, the subjects will initiate mepolizumab at the time point that would have been Week 60 if the subject had completed the study. Eligible subjects will receive subcutaneously administered mepolizumab at a dose of 300 mg SC every 4 weeks. Eligible subjects will continue to receive mepolizumab under this LAP until mepolizumab is commercially licensed for the treatment of EGPA in the relevant country or until GlaxoSmithKline (GSK) discontinues the program or until the subject meets any of the withdrawal/stopping criteria.

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)
Time Frame: Up to approximately 89 Months
An AE is any untoward medical occurrence in a subject, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. SAE is defined as any untoward medical occurrence that, at any dose: results in death; is life-threatening; requires hospitalization or prolongation of existing hospitalization; results in disability/incapacity; is a congenital anomaly/birth defect; other important medical events based on medical or scientific judgment; and is associated with liver injury and impaired liver function. Additionally, systemic (that is, allergic/hypersensitivity and non-allergic) reactions and local injection site reactions were recorded throughout the treatment and follow-up period.
Up to approximately 89 Months
