About this study

Official title: The Study of Acid Reflux in Asthma

The purpose of this study is to determine if subjects with symptomatic asthma who are assigned to treatment with a proton pump inhibitor (PPI) drug such as Nexium have fewer asthma attacks than similar subjects assigned to placebo treatment.

Read the detailed description

BACKGROUND:

Gastroesophageal reflux (GERD) is frequent in asthmatics with poor asthma control, often occurs without symptoms, and can induce bronchoconstriction. Poorly controlled asthmatics are often treated for GERD with drugs that suppress gastric acid, but this treatment is expensive and the benefit of such treatment is not established. Proton pump inhibitors are a relatively new class of medications that provide highly effective treatment for GERD and associated problems. This success has led many doctors to begin PPI treatment in their asthma patients in an attempt to achieve better asthma control.

DESIGN NARRATIVE:

The randomized, placebo-controlled trial will enroll 400 asthmatics, ages 18 or older, who have poor asthma control on inhaled steroids, defined on the basis of excessive bronchodilator use, nocturnal awakenings, or frequent exacerbations. Participants will be randomly assigned to treatment with either a proton pump inhibitor, esomeprazole (Nexium) 40 mg twice a day, or matching placebo. The presence, severity, and temporal relationship of GERD to asthma symptoms will be documented with 24 hour ambulatory esophageal potential Hydrogen (pH) probe monitoring, but participants will be enrolled irrespective of the severity of GERD. The primary outcome measure is the proportion of participants who have exacerbations of asthma within a 6-month period defined by asthma diaries and interviews. Secondary outcome measures include asthma symptom and control scores, asthma-specific and generic health-related quality of life, GERD symptoms, health care use, pulmonary function, and airways reactivity. Pre-specified subgroup analyses will be conducted to determine if there are clinical or demographic characteristics that predict benefit from treatment of GERD in asthma.

What is being measured

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

  1. Episodes of Poor Asthma Control (EPAC) From Diary Cards, According to Definition That Did Not Include Use of Beta-agonists as a Criterion

    Episodes of poor asthma control was defined as any one of the following: 2 consecutive days with a drop in peak flow >=30% of baseline; urgent care for asthma; or new use of oral corticosteroids for asthma

    Measured: Baseline to 24 Weeks

Secondary outcomes (17)
  1. Exacerbation Components: >=30% Drop in Peak Expiratory Flow on 2 Consecutive Days

    Measured: Baseline to 24 Weeks

  2. Exacerbation Components: Urgent Care Visit

    Measured: Measured at Month 6

  3. Exacerbation Components: New Use of Oral Corticosteroids

    Measured: Baseline to 24 Weeks

  4. Asthma Episodes, According to Definition That Included Increased Use of Beta-agonists

    Measured: Baseline to 24 Weeks

  5. Use of Rescue Medications

    Increase in the use of rescue meds by 4 or more uses on a particular day above the average uses during the run-in period.

    Measured: Baseline to 24 Weeks

  6. Night Awakening

    Rate of awakening at night because of asthma symptoms

    Measured: Baseline to 24 Weeks

  7. Pulmonary Function: Change in Prebronchodilator FEV1

    Mean change in pre-bronchodilator FEV1 - forced expiratory volume in 1 second; a measure of pulmonary function. The treatment effect is the difference in the mean change in between the groups.

    Measured: Baseline to 24 Weeks

  8. Pulmonary Function: Change in Prebronchodilator Forced Vital Capacity

    Pulmonary function measured by mean change in Prebronchodilator forced vital capacity from baseline to 24 weeks

    Measured: Baseline to 24 Weeks

  9. Pulmonary Function: Change in Peak Flow Rate

    Mean change from baseline to 24 weeks in the peak flow rate - how forceful patient can blow out air

    Measured: Baseline to 24 Weeks

  10. Pulmonary Function: Change in PC20

    Mean Change in the dose of methacholine that results in a 20% drop in FEV1

    Measured: Baseline to 24 Weeks

  11. Change in Juniper Asthma Control Score(JACQ)

    Mean change. Scores on the JACQ range from 0 to 6, with lower scores indicating better asthma control and 0.5 as the minimal clinically important difference.

    Measured: Baseline to 24 Weeks

  12. Change in Asthma Symptom Utility Index (ASUI)

    Mean change. Scores on the ASUI range from 0 to 1, with higher scores indicating less severe asthma.

    Measured: Baseline to 24 Weeks

  13. Change in the Mini-Asthma Quality of Life Questionnaire (Mini-AQLQ)

    Mean change. Scores on the Mini-Asthma Quality of Life Questionnaire (mini-AQLQ)range from 1 to 7, with higher scores indicating better quality of life and 0.5 as the minimal clinically important difference.

    Measured: Baseline to 24 Weeks

  14. Change in Medical Outcomes Study Short-Form 36 Score Quality of Life Score: Physical Component

    Mean change. Scores on the Medical Outcomes Study Short-Form 36 range from 1 to 100, with higher scores indicating better quality of life and 5 as the minimal clinically important difference.

    Measured: Baseline to 24 Weeks

  15. Change in Medical Outcomes Study Short-Form 36 Quality of Life Score: Mental Component

    Mean change. Scores on the Medical Outcomes Study Short-Form 36 range from 1 to 100, with higher scores indicating better quality of life and 5 as the minimal clinically important difference.

    Measured: Baseline to 24 Weeks

  16. Change in Gastric Symptoms: Gastroesophageal Reflux Disease Symptom Assessment Scale Score

    Mean change. The Gastroesophageal Reflux Disease Symptom Assessment Scale score ranges from 0 to 3, with lower numbers indicating less distress.

    Measured: Baseline to 24 Weeks

  17. Change in Number of Gastric Symptoms: No. of Symptoms

    Mean change

    Measured: Baseline to 24 Weeks

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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 19 Oct 2012). 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?

Episodes of Poor Asthma Control (EPAC) From Diary Cards, According to Definition That Did Not Include Use of Beta-agonists as a Criterion (time frame: Baseline to 24 Weeks). 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 NCT00069823, which also lists 5 linked publications.

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 19 Dec 2012; AzTrials last refreshed its copy on 3 Nov 2026.
