Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 20 to 45 years
  • Men only
  • Healthy volunteers accepted
  • Adult

Who may be able to join

  • Healthy Japanese male subjects between 20 and 45 years of age
  • Genotype of CYP2C19 has been known as the volunteer panel data
  • H. pylori negative has been known by urea breath test as the volunteer panel data.

Who cannot join

  • Significant clinical illness from the 2 weeks preceding the pre-entry visit to the randomisation, as judged by the investigator(s), eg, acute inflammatory disease which requires medical intervention

About this study

Official title: A Randomised, Single Blind, Two-way Cross-over, Single-centre Study to Assess the Pharmacodynamics (Intragastric pH) and Pharmacokinetics After Repeated Oral Administration of D961H 10 mg and Omeprazole 10 mg in Japanese Healthy Male Subjects

The purpose of this study is to assess the pharmacodynamics (intragastric pH) after repeated oral administration of D961H 10 mg and omeprazole 10 mg in Japanese healthy male subjects who are classified by the genotype of CYP2C19 by the assessment of percentage of time with intragastric pH>4 during 24 hours after dose on day 5.

What is being measured

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

  1. To assess the pharmacodynamics (intragastric pH) after repeated administration of D961H 10 mg and omeprazole 10 mg in Japanese healthy male subjects by the assessment of percentage of time with intragastric pH>4.

    Measured: A range of 24 hrs

Secondary outcomes (3)
  1. To assess the pharmacodynamics (intragastric pH) after repeated administration of D961H 10 mg and omeprazole 10 mg by the assessment of percentage of time with intragastric pH>3 during 24 hours and 24-hour median intragastric pH.

    Measured: A range of 24 hrs

  2. To assess the pharmacokinetics after repeated administration of D961H 10 mg and omeprazole 10 mg by the assessment of plasma concentrations and AUCt, AUCt, Css,max, tmax, and t1/2 for D961H and omeprazole after dose on day 5.

    Measured: A range of 24 hours

  3. To assess the safety and the tolerability after repeated administration of D961H 10 mg and omeprazole 10 mg by the assessment of adverse events, laboratory variables, pulse rate, blood pressure, body temperature and 12-lead ECG

    Measured: Until last visit, 5-7 days after last dose

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing D961H and Omeprazole in people with Pharmacodynamics Study, run by AstraZeneca at 1 site in Japan.

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 3 inclusion and 3 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 21 Sep 2010. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Japan. Whether a site is taking part right now should be confirmed with that site. See every site.

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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

To assess the pharmacodynamics (intragastric pH) after repeated administration of D961H 10 mg and omeprazole 10 mg in Japanese healthy male subjects by the assessment of percentage of time with intragastric pH>4. (time frame: A range of 24 hrs). 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 21 Sep 2010.
