Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 55 years
  • All sexes
  • Healthy volunteers accepted
  • Adult

Who may be able to join

  • Healthy male and/or female volunteers aged 18 to 55 years (inclusive) with suitable veins for cannulation or repeated venipuncture. (Healthy as determined by medical history and physical examination, laboratory parameters, and ECG performed before the first administration of the IP)
  • Female volunteers must have a negative pregnancy test at Visit 1 and on admission (Day -1 of Visit 3 and Visit 5) to the study centre, must not be lactating and must be of non childbearing potential
  • Be able to produce a minimum of 100 mg sputum (pellet weight) of good quality with total cell count (defined as total cell count <14 x 106/g, eosinophils <3%, sputum neutrophil % differential <65%, <30% squamous cell contamination and a minimum of 50% ce

Who cannot join

  • History of any clinically important disease or disorder which, in the opinion of the Investigator, may either put the volunteer at risk because of participation in the study, or influence the results or the volunteer's ability to participate
  • Any infection within the previous 4 weeks. Volunteers who get an infection between Visit 1 and admission to the centre can be rescreened

About this study

Official title: A Double Blind, Randomised, Placebo-controlled, 2-period, Cross-over Study in Healthy Volunteers to Investigate the Effects of a Single Dose of Inhaled AZD7624 on White Blood Cells and Inflammatory Markers in Induced Sputum and Blood After Oral Inhalation of 45,000 Endotoxin Units Lipopolysaccharide (LPS)

Study to investigate the effect of a single dose of AZD7624 on inflammation caused by an endotoxin challenge.

Read the detailed description

This is a double-blind, randomised, placebo controlled, 2-way cross-over study to investigate the effects of a single dose of inhaled AZD7624 on white blood cells and inflammatory markers in induced sputum and blood after oral inhalation of LPS as well as the safety, tolerability and pharmacokinetics (PK) of AZD7624 following a single inhaled dose.

Being tested
AZD7624, Placebo

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Description of the pharmacodynamic Neutrophil lipopolysaccharide (LPS) response after a single dose AZD7624 in terms of % change in neutrophil differential from baseline

    Measured: Sample taken at baseline visit (7-14 days before dose) and at 6h after dose day1 for each treatment. (up to 7 weeks)

Secondary outcomes (2)
  1. Description of the efficacy in terms of effect of a single dose of inhaled AZD7624 on levels of TNF-α induced sputum after oral inhalation of LPS will be evaluated compared to placebo

    Measured: Sample taken at baseline visit (7-14 days before dose) and at 6h after dose day1 for each treatment. (up to 7 weeks)

  2. Description of the safety profile in terms of Adverse events; blood pressure, heart rate and body temperature; electrocardiograms; clinical chemistry ,Creatinin kinase and myoglobin; haematology assessments, and forced expiratory volume in one second

    Measured: From Screening to follow up (up to 9 weeks)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing AZD7624 in people with LPS Challenge, Neutrophils, run by AstraZeneca at 1 site in United Kingdom.

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 5 inclusion and 5 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 7 May 2014. 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 United Kingdom. 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. Some participants in this study may receive a placebo. 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?

Description of the pharmacodynamic Neutrophil lipopolysaccharide (LPS) response after a single dose AZD7624 in terms of % change in neutrophil differential from baseline (time frame: Sample taken at baseline visit (7-14 days before dose) and at 6h after dose day1 for each treatment. (up to 7 weeks)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 7 May 2014.
