What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Ivabradine and placeboDrug
Also called Ivabradine, Placebo
Single and repeated oral administrations of 3 doses of ivabradine (2.5, 5, and 10 mg). Subjects were given a single administration of ivabradine during Period 1 (P1), following a 3-day washout, they were given repeated administrations twice daily for 4.5 days during Period 2 (P2).
| Study group | Role | What they receive |
|---|---|---|
| Ivabradine | Active comparator | Single and repeated oral administrations of 3 doses of ivabradine Receives: Drug: Ivabradine and placebo |
| Placebo | Placebo comparator | Placebo administration Receives: Drug: Ivabradine and placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
Cmax,tmax, AUC(Area under the time-concentration curve) of ivabradine and metabolite
For PK measurements, blood samplings were done: pre-dose then 20 min, 40 min, 1 h, 1.5 h, 2 h, 3 h, 4 h, 5 h, 6 h, 8 h, 10 h, 12 h, 16 h, 24 h, 36 h, 48 h, 60 h, and 72 h following the D1 single administration (P1) and the Day 8 (D8) last repeated dose (P2), respectively.Ivabradine and its main metabolite were determined using LC-MS/MS, then pharmacokinetic parameters were calculated by noncompartmental approach. Descriptive statistics were performed on the PK individual parameters calculated from the plasma concentration-time profiles.
Measured: within 60 days after blood sampling (blood sample analysis)
Secondary outcomes (1)
pharmacodynamics: The change of heart rate between baseline and over 24-hour, diurnal, nocturnal, awake, and asleep periods after administration of ivabradine
For PD measurements, 24-hour Holter recordings were performed on Day0, Day1, Day8, and Day10. a resting 12-lead ECG were also performed.
The changes of heart rate between day 1 and baseline values, between day 8 and baseline values were studied over 24-hour, diurnal, nocturnal, awake and asleep period for each ivabradine dose in comparison with placebo. Descriptive statistics by dose were performed and confidence intervals of the differences between each dose of ivabradine and placebo were constructed using a non-parametric method based on Hodges \& Lehman estimate for independent samples.
Measured: within 10 days after administration

Questions about this trial
What is this clinical trial studying?
A Phase 1 study of Healthy Individual, run by Asan Medical Center 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 7 inclusion and 9 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 5 Mar 2013. 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. 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 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?
Cmax,tmax, AUC(Area under the time-concentration curve) of ivabradine and metabolite (time frame: within 60 days after blood sampling (blood sample analysis)). 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 5 Mar 2013.
