Trial summary

The addition of an inhaled long-acting beta-adrenergic agonist to an inhaled glucocorticosteroid improves disease control in persistent asthma. This observation has supported the use of long-acting beta-adrenergic agonist/glucocorticosteroid combination preparations for the management of asthma. Read more about this study

About this study

The addition of an inhaled long-acting beta-adrenergic agonist to an inhaled glucocorticosteroid improves disease control in persistent asthma. This observation has supported the use of long-acting beta-adrenergic agonist/glucocorticosteroid combination preparations for the management of asthma. Currently, salmeterol/fluticasone and formoterol/budesonide are available for clinical use. The long-term beneficial clinical effects of the two drug classes seem to be synergistic, and several mechanisms of glucocorticoid-beta-adrenergic agonist interactions involving gene transcription have been invoked to explain this phenomenon.This study, wish to address the question whether glucocorticoids can acutely potentiate the bronchodilator response to a long-acting beta-adrenergic agonist.We expect that in patients with asthma, the short-term bronchodilator effect of salmeterol is enhanced by the addition of fluticasone, which by itself has no short-term bronchodilator effect. To test this premise, we will assess the respective short-term effects of salmeterol (50 µg), fluticasone (250 µg), salmeterol/fluticasone (50/250 µg), and placebo/placebo on spirometric parameters. Airway Blood flow will also be measured to ensure that vasoconstriction does not occur.

Read the detailed description

Fourteen lifetime nonsmokers with a physician diagnosis of asthma will be recruited for the study. All subjects will be allowed to use short-acting beta-adrenergic agonists as rescue medication.

Inclusion criteria:

  1. Males and females, 18 to 65 years of age.
  2. FEV1 60-85% of predicted on the screening day.

Exclusion criteria:

  1. Women of childbearing potential who do not use accepted birth control measures; pregnant and breast feeding women.
  2. Cardiovascular disease and/or use of cardiovascular medications
  3. Subjects with known beta-adrenergic agonist or glucocorticosteroid intolerance 4. Acute respiratory infection within four weeks prior to the study 5. Use, within two weeks prior to the study, of any anti-asthma medication not mentioned above

Questions about this trial

What is this clinical trial studying?

A study testing fluticasone, Salmeterol and fluticasone/salmeterol in people with Asthma, run by University of Miami.

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 2 inclusion and 2 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 30 Jun 2016. Status can change between updates, so confirm with the study contact before making plans.

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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 10 Dec 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Maximum Change From Baseline in Airway Blood Flow (Qaw) (time frame: maximum change in Qaw within 240 minutes post drug inhalation). 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 NCT01231230, which also lists 1 linked publication.

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 30 Jun 2016.
