Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 55 years (Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. 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)
  2. 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
  3. 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
  4. Have normoresponsive airways with a methacholine PC20 >16 mg/mL. Screening methacholine provocation is not required if the volunteer has been tested by the centre in the past 1 year, with documented records of this testing
  5. Be able to inhale from SPIRA nebuliser

Exclusion Criteria:

  1. 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
  2. Any infection within the previous 4 weeks. Volunteers who get an infection between Visit 1 and admission to the centre can be rescreened
  3. History of severe allergy/hypersensitivity or ongoing clinically important allergy/hypersensitivity, as judged by the Investigator or reason to expect untoward reactions to LPS and/or AZD7624
  4. History of chronic respiratory disease
  5. Volunteers who are vegans or have medical dietary restrictions -

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
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)
Sample taken at baseline visit (7-14 days before dose) and at 6h after dose day1 for each treatment. (up to 7 weeks)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
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
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)
Sample taken at baseline visit (7-14 days before dose) and at 6h after dose day1 for each treatment. (up to 7 weeks)
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
