October 10, 2012 updated by: MedImmune LLC

A Prospective Observational Study to Assess the Role of Selected Biomarkers in Subjects Requiring Daily Medium- to High-dose Inhaled Corticosteroids for Persistent Asthma

The rationale for conducting this study is to explore potential clinical and peripheral biomarkers in subjects requiring daily medium to high dose inhaled corticosteroids for persistent asthma

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

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

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Adults with asthma on stable medium- to high-dose inhaled corticosteroids.

Description

Inclusion Criteria:

  • Age 18 through 75 at the time of screening
  • Written informed consent and any locally required authorization obtained from the subject prior to performing any protocol-related procedures, including screening evaluations
  • History of physician-diagnosed asthma for at least 12 months prior to screening
  • Stable Medium- to high-dose ICS divided twice daily as outlined by the NHLBI Asthma Guidelines, 2007

Exclusion Criteria:

  • Any medical condition that, in the opinion of the investigator or medical monitor, would interfere with interpretation of subject safety or study results
  • Concurrent enrollment in another clinical study
  • Use of immunosuppressive medication within 3 months prior to screening
  • Acute upper or lower respiratory infections requiring antibiotics or antiviral medications with in 30 days prior to screening or during screning period.
  • Receipt of immunoglobulin or blood products within 30 days prior to screening or during the screening period
  • Receipt of any investigational non-biological drug therapy within 30 days or 5 half-lives prior to screening whichever is longer; or receipt of any marketed or investigational biologic within 6 months or 5 half-lives prior to screening whichever is longer
  • Pregnant, lactating, or breastfeeding woman
  • Diagnosis of lung disease other than persistent asthma
  • History of smoking ≥10 pack years or any smoking within 12 months prior to screening
  • History of active, infectious hepatitis A, B, C or human immunodeficiency virus (HIV)

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
To identify an optimal prediction rule for classifying sputum eosinophilic and non-eosinophilic asthmatics.
Time Frame: 8 Days
Variables representing lung function tests, patient reported outcomes, and blood biomarkers will be evaluated singly and in various combinations.
8 Days

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
To assess which markers are associated with sputum eosinophils.
Time Frame: 8 Days
Comparing lung function tests between eosinophilic and non-eosinophilic subjects.
8 Days
To assess which markers are associated with sputum eosinophils

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
January 1, 2011

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
April 1, 2012

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
