About this study

Official title: A Single Blind, Placebo Controlled, Parallel Group, Single Ascending Intravenous Dose Study to Assess Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of SB-240563 (Mepolizumab) in Healthy Japanese Male Subjects.

SB-240563 is a fully humanized monoclonal antibody which is specific for human interleukin-5 (IL-5) and has been under development for severe refractory asthma. This study is the first study in Japanese subjects. The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of single dose SB-240563 administered intravenously to Japanese healthy male subjects.

Read the detailed description

Asthma is a disease characterised by chronic airway inflammation, bronchial hyper-reactivity and variable airflow obstruction. Eosinophils are usually prominent in the airway inflammation seen in asthma and are considered a central cause in the pathogenesis of asthma. The expression of interleukin (IL)-5 is elevated in bronchoalveolar lavage (BAL) fluid and bronchial biopsies in patients with asthma. Moreover, the level of IL-5 in BAL fluid and the bronchial mucosa correlates with disease severity. The cytokine IL-5 promotes eosinophil differentiation, recruitment and survival. Thus a therapeutic strategy which blocks IL-5, thereby suppressing eosinophilic inflammation, may have therapeutic benefit in asthma.

SB-240563 (mepolizumab) is a humanized monoclonal antibody that blocks human interleukin 5 (hIL-5) from binding to its receptor. Initial clinical studies investigated the safety and efficacy of SB-240563 for the treatment of asthma and atopic dermatitis (AD). SB-240563 consistently and significantly reduced peripheral and tissue eosinophils in patients with these atopic conditions, including asthma, and in healthy volunteers.

SB-240563 is currently under development for severe refractory asthma and a Phase IIB dose-ranging study using the IV route of administration is currently ongoing. This study will be a single-blind, placebo-controlled, parallel group, dose ascending, single dose study in Japanese healthy male subjects.

Since this is the first study conducted in Japanese subjects, doses of SB-240563 will be administered in an ascending order. In studies conducted in non-Japanese subjects, SB-240563 has been well-tolerated following single and repeated intravenous dose up to 750 mg (SB-240563/006, SB-240563/036 and MEE103226). Intravenous repeated doses of 75 mg, 250 mg and 750 mg are being administered to non-Japanese asthma patients in an on-going Phase II study. In consideration of the above facts, single intravenous administration of 4 doses (10 mg, 75 mg, 250 mg and 750 mg) of SB-240563 will be administered in this study. A single intravenous dose of 10 mg will be administered in order to explore the effect of a lower dose of SB-240563 than previously studied on blood eosinophil counts. This low dose is expected to help further characterize the concentration-response relationship based on blood eosinophils.

This study is designed as a randomized, parallel group, placebo-controlled, single-blind study to evaluate the pharmacokinetics, pharmacodynamics, safety and tolerability of SB-240563 in Japanese male subjects.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing SB-240563 in people with Asthma, run by GlaxoSmithKline at 1 site in Australia.

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 7 inclusion and 16 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 20 Jun 2017. 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 Australia. 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 phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

pharmacokinetics (time frame: From Day 1 to Follow-Up(Days 85 for Cohort 1 and 2, Days 121 for Cohort 3, Days 151 for Cohort 4)). 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 NCT01471327, which also lists 8 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 20 Jun 2017.
