Evaluation of Volatile Organic Compounds in Mepolizumab Therapy

Status Not yet recruiting

Clinical Trial Summary

This study will recruit patients who are being prescribed Mepolizumab as part of their standard clinical care for the treatment of severe eosinophilic asthma. Over the course of their treatment, research data (questionnaires) and research samples (blood, breath and urine) will be collected in parallel to standard clinical measurements. The data and samples will be investigated to help better understand how Mepolizumab works, why it doesn't work in certain patients and why it works very well in others. This will help prescribers better identify patients that will benefit from Mepolizumab.

Clinical Trial Description

EVOC4M is a prospective observational study investigating Mepolizumab in the treatment of severe eosinophilic asthma. This study will recruit patients receiving Mepolizumab as part of their standard clinical care in an NHS commissioned Specialised Adult Severe Asthma Service. Over the course of their treatment, research data (questionnaires) and research samples (blood, breath and urine) will be collected in parallel to standard clinical measurements. Clinical studies have demonstrated blood eosinophil levels to be predictive of the magnitude of the impact of Mepolizumab in reducing severe disease exacerbations but it is appreciated that there are still treatment failures despite this selection criteria. Clinical decision and policymaking are increasingly concerned by the health economic implications of these high-cost therapies and so clinical biomarkers are now being sought for theragnostics: prediction of treatment response The study will try to identify biomarkers that will can discriminate between those that respond to Mepolizumab ("responders") and those that do not ("non-responders"). This will improve our understanding of how Mepolizumab works. In particular, the investigators are interested in exhaled volatile organic compounds (VOCs), which are measured in exhaled breath samples. Exhaled breath is safe and easy to collect and has direct contact with the organ of interest, the airways. A VOC biomarker that predicts Mepolizumab success may translate to clinical practice. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
