Trial overview
Official title: An open-label, single arm, repeat dose, multi-centre study to evaluate the use of an autoinjector for the subcutaneous administration of mepolizumab in subjects with severe eosinophilic asthma (Study 204959)
Trial description: This study is aimed to assess the correct real-world use of an autoinjector for the repeat self-administration of mepolizumab SC, so to improve subject / physician convenience and to enable repeat dose self injection themselves or via caregivers. This Phase III study will be an open-label, single-arm, repeat-dose, multi-centre study of mepolizumab liquid drug product in autoinjector (100 milligrams [mg]) administered subcutaneously (SC) every 4 weeks (3 doses) in subjects with severe eosinophilic asthma. Subjects will receive 100 mg mepolizumab SC as a single injection that is self-administered in the thigh, abdomen or administered in the upper arm (caregiver only). Each subject will participate in the study for up to 18 weeks including pre-screening visit, a screening visit and a 12-week treatment period which concludes with end of study assessments (Visit 5) 4 weeks after the last dose of mepolizumab. Approximately 158 subjects will be enrolled in the study.

No
- 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.
- Concurrent respiratory disease: 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.
- Eosinophilic diseases: 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 will also be excluded.
Inclusion and exclusion 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. (Subjects will be permitted to be enrolled without continuous high dose ICS providing the subject was receiving continuous ICS and the Investigator attest that the subject should have been treated with high dose ICS to mitigate the risk of exacerbations, or the subject has financial or tolerance issues that prevent the use of high-dose ICS. Such subjects should be discussed with GSK Medical Monitor prior to enrolment)
- 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.
