About this study

Official title: Bioequivalence of Levamlodipine Besylate Tablets in Healthy Chinese Subjects: A Single-dose and Two-period Crossover Study

The single-dose randomized, open-label, two-period crossover study was executed in the Phase I Clinical Research Center of the Affiliated Hospital of Qingdao University. According to the random table generate by SAS 9.4, the subjects were divided into two groups at the ratio of 1:1. The select qualified volunteers were hospitalized in the Phase I Clinical Research Center, and fasted for 10 hours overnight until administration. The medicine was swallowed with 240 ml water at room temperature. Blood samples were taken before administration and at 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 14, 24, 36, 48, 72, 96, 120, 144, 168 hours after administration. The samples were centrifuged at 1,800 g for 10 min at 4 °C to separate the plasma. The plasma samples were divided into two aliquots and stored at -80 °C until bioanalysis. The half-life of levamlodipine is 30 ~ 50 hours. Washout period, the interval between two administration, is 21 days. In the two periods, the operation was kept the same.

Moreover, in high fat meal group, the high-fat breakfast was arranged within half an hour before taking the medicine. Other procedures were the same as those in the fasting group.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Amlodipine 10 mg and Levamlodipine 5 mg in people with Healthy Subjects, run by The Affiliated Hospital of Qingdao University at 1 site in China.

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 2 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 Jun 2020. 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 China. 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?

Peak Plasma Concentration (Cmax) (time frame: 64 days). The study lists 3 primary outcomes in all. 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 NCT04411875, which also lists 1 linked publication.

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 Jun 2020.
