NCT ID: NCT03453021 Completed - Clinical trials for Asthma; Eosinophilic

Effect of Mepolizumab on Decrease of Systemic Corticosteroids in Patients With Severe Eosinophilic Asthma

Mepolizumab
Start date: January 25, 2016
Phase:
Study type: Observational [Patient Registry]

The primary objective of the study is to measure the effect of mepolizumab on declines in oral corticosteroid therapy (prednisolone or prednisone) in patients with severe eosinophilic asthma. Asthma is a chronic inflammatory disease of the airways that affects 5 to 10% of adults and children. Despite current treatments that are often effective, 10% of patients are not controlled by inhaled therapies. These severe asthma require regular use of systemic corticosteroids in 30 to 40% of cases. In this context, the use of glucocorticoids is associated with many more or less serious adverse effects, but still affecting the patient's quality of life. Several treatments have already been proven to save systemic steroids (theophylline, anti-leukotrienes, golimumab ...). On the other hand, none is currently recommended because of a risk / benefit ratio that is too high. Mepolizumab is a human monoclonal antibody that binds to and inactivates interleukin 5. It has recently been shown to be effective in reducing the daily dose of oral corticosteroids and in reducing exacerbations in these patients with severe eosinophilic asthma. It also reduces the number of eosinophils in the blood and sputum and improves the quality of life. Patients will receive a subcutaneous injection of 100mg mepolizumab every 4 weeks for one year, for a total of 12 injections. In France, this treatment was subject to a Temporary Authorization for Nominative Use in severe eosinophilic asthma and is reserved for hospital use. The injections will be done in HDJ Pneumology CHU Grenoble Alpes and patients will be followed monthly during injections and one month after the end of injections.

NCT ID: NCT02654145 Completed - Asthma Clinical Trials

Omalizumab to Mepolizumab Switch Study in Severe Eosinophilic Asthma Patients

Start date: March 17, 2016
Phase: Phase 4
Study type: Interventional

Mepolizumab is an anti-interleukin-5 ( IL-5) monoclonal antibody that neutralizes IL-5 and reduces eosinophil counts in both sputum and blood. Omalizumab an anti-immunoglobulin E (IgE) monoclonal antibody (mAb) is effective in the treatment of moderate to severe allergic asthma. The aim of this study is to investigate whether subjects not optimally controlled on their current omalizumab treatment, who are eligible for therapy with mepolizumab can be effectively and safely switched to treatment with mepolizumab to improve asthma control. The study will provide data on the efficacy, safety, immunogenicity, and tolerability of mepolizumab when switched directly from omalizumab without any wash-out. The learnings from this study may help guide physicians when substituting one biologic with another for the treatment of patients with severe eosinophilic asthma. The study will be a multi-centre, open-label single arm trial. Patients with severe eosinophilic asthma who are receiving omalizumab, but are not optimally controlled will be eligible to participate. Subjects will remain on their current maintenance therapy including omalizumab throughout the run-in period for a minimum of one week and up to 4 weeks. At Visit 2 (week 0) subjects will discontinue their omalizumab treatment and be switched to mepolizumab 100 mg subcutaneous (SC) every 4 weeks for 28 weeks. The treatment period is 32 weeks, including an Exit Visit/Early Withdrawal Visit, 4 weeks following the subject's last dose of mepolizumab.

NCT ID: NCT02560610 Completed - Clinical trials for Severe Eosinophilic Asthma

Effect of OC000459 on Eosinophilic Airway Inflammation in Severe Asthma

Start date: September 2016
Phase: Phase 2
Study type: Interventional

The aim is to study the effect of OC000459 on eosinophilic airway inflammation and asthma control in subjects with severe, refractory eosinophilic asthma.

NCT ID: NCT02559791 Completed - Clinical trials for Severe Persistent Asthma

Anti-Interleukin-5 (IL5) Monoclonal Antibody (MAb) in Prednisone-dependent Eosinophilic Asthma

Start date: October 2015
Phase: Phase 2/Phase 3
Study type: Interventional

The steroid sparing effect of anti interleukin (IL-5) monoclonal antibody has been proven, but the effectiveness of subcutaneous (SC) compared to intravenous (IV) administration of these drugs to suppress airway eosinophilia is still under debate. As part of a previous study, 100mg of mepolizumab were administered subcutaneously to a group of subjects with prednisone-dependent eosinophilic asthma. Despite this intervention, 50% of the subjects (15 patients participated in this study) had persistently elevated sputum eosinophil counts. The same 15 patients will be invited to participate in the current study, and if they provide their informed consent, will receive 2 monthly doses of placebo, followed by 4 monthly doses of IV reslizumab. The primary outcomes are blood and sputum eosinophils, and the secondary outcomes include sputum and blood Innate lymphoid cell-2 (ILC2) cells, cluster of differentiation 4 (CD4+) cells, cluster of differentiation-8 (CD8+) cells, cluster of differentiation-34 (CD34+), Eosinophil-Basophil cluster cells (Eo/B progenitor cells), forced expired volume in 1 second (FEV1), asthma control questionnaire (ACQ) and number of eosinophilic exacerbations. Measurements of the outcomes will be done before placebo, after placebo and after IV reslizumab. This study design will determine whether IV reslizumab is effective in suppressing airway eosinophilia in prednisone-dependent patients.

NCT ID: NCT02555371 Completed - Asthma Clinical Trials

Cessation Versus Continuation of Long-term Mepolizumab in Severe Eosinophilic Asthma Patients

Start date: January 7, 2016
Phase: Phase 3
Study type: Interventional

Primary objective of the study is to evaluate whether patients with severe eosinophilic asthma who have received long-term treatment with mepolizumab (at least 3 years) need to maintain treatment with mepolizumab to continue to receive benefit. Subjects who participated in the open-label studies MEA115666 or 201312 with at least 6 months of treatment with mepolizumab prior to Visit 1 and who have no more than 2 consecutive missed doses of mepolizumab treatment will be eligible to participate in this study. This study will be conducted in 4 parts in approximately 300 subjects. Part A will be Variable Open-Label Run-in (for subjects with less than 3 years of mepolizumab treatment). Once the required 3 year exposure is reached, subjects will enter Part B- Fixed Open-Label Run-In (4 weeks to 8 weeks). During Part A and B subjects will be administered Open-label mepolizumab (100 milligram [mg] Subcutaneous [SC]) every 4 weeks. Part C will be the randomized double-blinded part. Upon completion of Part B, eligible subjects will be randomized to mepolizumab (100 mg SC) every 4 weeks or placebo administered SC every 4 weeks for 52 weeks. Subjects discontinuing investigational product (IP) due to a clinically significant asthma exacerbation will then enter optional Part D of the study. During Part D, subjects receive open-label mepolizumab in addition to their standard of care therapy for the remainder of the study, through Part D up to 52-weeks post-randomization. An Exit Visit will be conducted 52 weeks after randomization in order to assess subject's efficacy parameters, immunogenicity status, and to conduct additional safety assessments. Eligible subjects will participate in the study ranging from 56 to192 weeks, depending on the duration of Part A (0 to 132 weeks) and Part B (4 to 8 weeks).

NCT ID: NCT02281318 Completed - Asthma Clinical Trials

Efficacy and Safety Study of Mepolizumab Adjunctive Therapy in Participants With Severe Eosinophilic Asthma on Markers of Asthma Control

Start date: December 11, 2014
Phase: Phase 3
Study type: Interventional

This is a multi-centre, placebo-controlled, double-blind, parallel-group study to evaluate the efficacy and safety of mepolizumab adjunctive therapy in participants with severe eosinophilic asthma on markers of asthma control. The overall intent of the current study is to more fully explore the impact of mepolizumab on health-related quality of life (HR-QoL) and other measures of asthma control, including lung function. Participants who meet the predefined criteria will be randomised to receive either mepolizumab or placebo in addition to standard of care asthma treatment. Approximately 780 participants with severe eosinophilic asthma will be screened to ensure the randomisation of 544 participants (272 participants per treatment group) into the study.
