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 multicentre, randomized, double-blind, parallel group, placebo-controlled, phase 2 study to designed evaluate the effect of a 300 mg dose of tralokinumab administered subcutaneously every 2 weeks on airway inflammation in adults with asthma inadequately controlled on inhaled corticosteroids (ICS) with or without other controllers. Approximately 80 subjects will be randomized. Subjects will receive tralokinumab, or placebo, administered via subcutaneous injection at the study site, over a 12 week treatment period.

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.

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 75 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

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
Measure Description
Time Frame
Change From Baseline to Week 12, Expressed as a Ratio, in Number of Airway Submucosal Eosinophils
Time Frame: Baseline (Week 0) and Week 12
The number of airway submucosal eosinophils per millimetre squared (mm^2) was determined by microscopic evaluation of bronchoscopic biopsies. The ratio of post-randomisation value at Week 12 to baseline value was computed as (Week 12 value / baseline value). The change from baseline to Week 12 (ratio) in the number of airway submucosal eosinophils is presented as geometric mean ± standard deviation (SD) of log values.
Baseline (Week 0) and Week 12

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
Measure Description
Time Frame
Change From Baseline to Week 12, Expressed as a Ratio, in Number of Blood Eosinophils
Time Frame: Baseline (Week 0) and Week 12
The blood eosinophil count was obtained from the total and differential white blood cell counts. The ratio of post-randomisation value at Week 12 to baseline value was computed as (Week 12 value / baseline value). The change from baseline to Week 12 (ratio) in the number of blood eosinophils is presented as geometric mean ± SD of log values.
Baseline (Week 0) and Week 12
Change From Baseline to Week 12, Expressed as a Ratio, in Number of Differential Sputum Eosinophils
Time Frame: Baseline (Week 0) and Week 12
Sputum induction was performed to obtain satisfactory samples of sputum originating from the airways. The ratio of post-randomisation value at Week 12 to baseline value was computed as (Week 12 value / baseline value). The change from baseline to Week 12 (ratio) in the number of eosinophils in induced sputum is presented as geometric mean ± SD of log values.
Baseline (Week 0) and Week 12
Change From Baseline to Week 12, Expressed as a Ratio, in Blood Free Eosinophil Cationic Protein (ECP) Concentrations
Time Frame: Baseline (Week 0) and Week 12
ECP concentrations were determined to assess evidence of activation of eosinophils in blood. The ratio of post-randomisation value at Week 12 to baseline value was computed as (Week 12 value / baseline value). The change from baseline to Week 12 (ratio) in blood free ECP concentrations is presented as geometric mean ± SD of log values.
Baseline (Week 0) and Week 12
Change From Baseline to Week 12, Expressed as a Ratio, in Sputum Free ECP Concentrations
Time Frame: Baseline (Week 0) and Week 12
ECP concentrations were determined to assess evidence of activation of eosinophils in sputum. The ratio of post-randomisation value at Week 12 to baseline value was computed as (Week 12 value / baseline value). The change from baseline to Week 12 (ratio) in sputum free ECP concentrations is presented as geometric mean ± SD of log values.
