About this study

Official title: Route of Administration of Anti-IL5 Monoclonal Antibody in Prednisone-dependent Eosinophilic Asthma

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.

Read the detailed description

Study design

Blinded placebo-controlled sequential clinical trial of 4 monthly doses of intravenously administered reslizumab.

The study will include two periods:

Period 1: After establishing the minimum dose of prednisone to observe sputum eosinophils ≥3% and blood eosinophils ≥300/µL, all subjects will receive 2 infusions (once monthly) of matching placebo.

Period 2: All subjects will then receive 4 infusions (once monthly) of reslizumab 3mg/kg.

Methods

15 patients (all of whom had sputum eosinophils ≥3% and blood eosinophils ≥300/µL) who were previously treated with S/C100 mg mepolizumab for at least 6 months, with the last dose at least 4 months before entering the study, will be invited to participate in the study.

Since discontinuing mepolizumab, these patients would have been re-established on their maintenance dose of daily prednisone + high doses of inhaled corticosteroids (ICS) and long acting beta agonist (LABA).

Baseline measurements of blood and sputum eosinophils, spirometry, symptoms (ACQ), and immune cells in blood and sputum (ILC2 cells, CD4 + cells, CD8+ cells, CD34+ Eo/B progenitor cells) will be enumerated by flow cytometry, and measures of local autoimmunity, using our established protocols at the start of Period 1 (baseline measurement).

They will then receive 2 infusions of placebo at monthly intervals, and measurements will be repeated at the end of Period 1 (post-placebo measurement).

The subjects will then receive by 4 infusions of 3 mg/kg reslizumab at monthly intervals. At the end of the 4 months, these measurements will be repeated (post-reslizumab measurement).

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Reslizumab in people with Severe Persistent Asthma and Eosinophilic Bronchitis, run by McMaster University at 1 site in Canada.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 4 Apr 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Sputum eosinophil percentage (time frame: Measured before the placebo phase (week 2), after 2 infusions of placebo (week 10), and after 4 infusions (week 26) of reslizumab 3mg/kg). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02559791, which also lists 19 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Apr 2018.
