Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Interventional(has expanded access)
Description of intervention(s) / exposure
Treatment: Other - Mepolizumab
Treatment: Drugs - SOC

Experimental: Mepolizumab 100 mg - All subjects will receive mepolizumab 100mg administered SC into the upper arm or thigh approximately every 4 weeks.


Treatment: Other: Mepolizumab
Mepolizumab is a fully humanised IgG antibody (IgG1, kappa) with human heavy and light chain frameworks. Mepolizumab will be supplied as a lyophilised cake in sterile vials for individual use.

Treatment: Drugs: SOC
Standard of Care (SOC) will differ by participant, however it will generally include oral corticosteroids and an inhaled controller medicine (an inhaled corticosteroid plus a long acting beta agonist) and/or short acting beta agonists

Summary
Brief summary
This is a multi-center, open-label, long-term study of subcutaneously (SC) administered mepolizumab 100mg in addition to standard of care (SOC), in subjects with severe eosinophilic asthma. This study will enroll a subset of subjects from Study MEA115661 who have demonstrated clear benefit from therapy and who without continuation of mepolizumab therapy are individuals at greatest risk of serious deterioration of their health status. In order to target individuals at greatest risk for serious deterioration of their health status, only subjects from the MEA115661 study with a history of life-threatening or seriously debilitating asthma, will be allowed to participate. Subjects meeting all of the eligibility criteria for the study will be offered the opportunity to consent for this study of up to 128 weeks in length (including the Follow-Up Visit). This study will give opportunity to extend the collection of clinical data for long-term use and further assess the sustainability of efficacy in a population likely to experience significant loss of asthma control and the need for higher doses of systemic steroids if returned to SOC only.
