About this study
Identification and evaluation of endogenous markers for the assessment of CYP3A activity using metabolomics.
Read the detailed description
Eligibility for participation of this study will be determined from demographic information, medical history, physical examination, electrocardiogram (ECG) and clinical laboratory tests within 3 weeks before study drug administration. Subjects suitable for this study will be admitted to the Clinical Trials Center, Seoul National University Hospital on the day before dosing, and they were overnight-fasted from 10 p.m. of Day -1. Urine collection is scheduled drug 24 hour before midazolam administration. Subjects will be dosed study drug via intravenous around at 9 a.m. of Day 1. Subjects performed scheduled procedures including clinical laboratory tests, electrocardiograms and pharmacokinetic samplings. Subjects will be discharged on Day 2, and visited Clinical Trials Center on Day 5-7 for ketoconazole administration. Subjects will be admitted on Day 7 for period 2. Subjects performed scheduled period 2 (ketoconazole co-administration phase), and period 3 (rifampicin co-administration phase) procedure. Study participation was terminated on post-study visit (Day 30-32).

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing midazolam in people with Healthy, run by Seoul National University Hospital at 1 site in South Korea.
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 5 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 23 Feb 2011. 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 South Korea. 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?
Metabolomic profile (time frame: -24- -12h, -12- 0h of every midazolam dosing). 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 23 Feb 2011.
