What is being measured

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

  1. Achievement of Sustained Difference in Inhibition of Intragastric Acidity Based on Median pH Values Between the Two Active Study Treatments at Steady-state on Day 7

    Median intragastric pH scores were collected at 5 minute intervals after treatment dose. The achievement of sustained difference was the earliest time for which a statistically significant difference was observed in the median intragastric pH scores for 3 consecutive 5-minute intervals. The earliest 3 time points for which a statistically significant difference was observed between the median intragastric pH values for the two active treatments for three consecutive 5-minute intervals are shown here.

    Measured: Treatment dose to 4-hr post-dose on Day 7

Secondary outcomes (17)
  1. Achievement of Sustained Difference in Inhibition of Intragastric Acidity Based on Median pH Values Between the Two Active Study Treatments at Steady-state on Day 1

    Median intragastric pH scores were collected at 5 minute intervals after treatment dose. The achievement of sustained difference was the earliest time for which a statistically significant difference was observed in the median intragastric pH scores for 3 consecutive 5-minute intervals. The earliest 3 time points for which a statistically significant difference was observed between the median intragastric pH values for the two active treatments for three consecutive 5-minute intervals are shown here.

    Measured: Treatment dose to 4-hr post-dose on Day 1

  2. The Difference in the Onset of Action Based on Median pH Values Between the Two Active Treatments Compared to No Treatment on Day 1 and Day 7

    Median intragastric pH scores were collected at 5 minute intervals after treatment dose. The difference in the onset of action was the earliest 5 minute interval (from start of interval to end of interval) for which each active treatment presented a statistically significantly advantage over No treatment based on median pH values. The earliest 5 minute interval showing the difference in onset of action is reported here.

    Measured: Treatment dose to 4-hr post-dose on Day 1 and Day 7

  3. Median Time to Achieve Intragastric pH > = 3.5 for a 10-Minute Period

    The time required to achieve an intragastric pH ≥3.5 that is reached for 10 consecutive minutes after drug administration on the 1st and 7th days of dosing.

    Measured: Treatment dose to 4-hr post-dose on Day 1 and Day 7

  4. Percentage Time Intragastric pH >4 During the First 4 Hours After Dosing on Day 7

    Measured: Treatment dose to 4 hours Post-dose on Day 7

  5. Median 24-hr Intragastric pH on Day 7

    The median intragastric pH values were recorded over a 24-hr period.

    Measured: Treatment dose to 24-hour post-dose on Day 7

  6. Percentage of Time Intragastric is pH >4 Over 24-hour Period on Day 7

    Measured: Treatment dose to 24-hour post-dose on Day 7

  7. Percentage of Time Intragastric pH >3.5 Over 24-hour Period on Day 7

    Measured: Treatment dose to 24-hours post-dose on Day 7

  8. Number of Participants With Intragastric pH >4 for More Than 50% of the Time on Day 7

    Number of participants maintaining intragastric pH > 4 for at least 12 hrs at

    steady-state on Day 7

    Measured: Treatment dose to 24-hour post-dose on Day 7

  9. Number of Participants With Intragastric pH >3.5 for More Than 50% of the Time on Day 7

    Number of participants maintaining intragastric pH > 3.5 for at least 12 hrs at

    steady-state on Day 7

    Measured: Treatment dose to 24-hour post-dose on Day 7

  10. Percentage of Time Intragastric pH >4 Over the Nocturnal Period on Day 7

    Measured: Treatment dose to 24-hour post-dose on Day 7

  11. Time to Achieve Sustained Intragastric pH > 3.5 at Steady-state on Day 7

    The first time to sustain median pH > 3.5 for at least 3 successive 5-minute periods within the first 2 hours after dosing with Zegerid Capsules, and Prevacid Capsules, or No treatment on the 7th day of respective treatments. If this condition was not met for any time point within the first 2 hours following dosing, a score of 120 minutes was imputed.

    Measured: Treatment dose to 2-hours post-dose on Day 7

  12. Time to Onset of Inhibition of Acid Secretion on Day 1

    The onset of inhibition of acid secretion was the first time to sustain median pH >3.5 for each of the twenty-four successive 5-minute periods. If this condition was not met for any time point within the first 4 hours following dosing, a score of 240 minutes was imputed.

    Measured: Treatment dose to onset of event on Day 1

  13. Number of Participants Maintaining Intragastric pH > 4 for at Least 12 Hours on Day 1

    Measured: Treatment dose to 24-hr post-dose on Day 1

  14. Number of Participants Maintaining Intragastric pH > 3.5 for at Least 12 Hours on Day 1

    Measured: Treatment dose to 24-hr post-dose on Day 1

  15. Percentage of Time Intragastric pH >4 Over the Nocturnal Period on Day 1

    Measured: Treatment dose to 24-hour post-dose on Day 1

  16. Percentage of Time Intragastric pH >4 During the First 4 Hours on Day 1

    Measured: Treatment dose to 4-hours post-dose on Day 1

  17. Time to Achieve Sustained Advantage Over No Treatment During the First 4 Hours After Dosing

    The earliest time during the first 4 hours after dosing that the median

    pH for the treatment is over 1 unit higher than that for the No treatment during the next three 5 minute intervals. (When this condition does not occur, the time to sustained advantage will be imputed as 4 hours.)

    Measured: Treatment dose to event on Day 1 and Day 7

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Zegerid and Prevacid® in people with Human Experimentation, run by Bayer.

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 5 inclusion and 12 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 11 Mar 2015. 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. 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 28 Jan 2011). 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?

Achievement of Sustained Difference in Inhibition of Intragastric Acidity Based on Median pH Values Between the Two Active Study Treatments at Steady-state on Day 7 (time frame: Treatment dose to 4-hr post-dose on Day 7). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 11 Mar 2015.
