About this study

Official title: A Single-center, Open-label Study Evaluating the Pharmacokinetics, and Safety of Multiple Dose Oral Brexpiprazole Tablets (1 mg) in Chinese Healthy Subjects

This study is a single-center, open-label study evaluating the pharmacokinetics and safety of multiple dose oral administration of Brexpiprazole (1 mg) tablets in Chinese healthy subject.10 healthy adult subjects will be enrolled in this study. A single dose (Brexpiprazole 1 mg) group is set and the test drug will be administered for 14 consecutive days.

Read the detailed description

10 healthy adult subjects will be enrolled in this study. A single dose (Brexpiprazole 1 mg) group is set and the test drug will be administered for 14 consecutive days.

After receiving the informed consent form the subject themselves, the investigators start the screening 14 days to 1 days prior to taking the study drug (D-14 to D-1).

One day before first dosing (D-1), subjects are hospitalized. On the next day (D1), after completed the hospitalization inspection, eligible subjects will be selected to start with the first dose, and from day 1 to day 14 (D1 to D14), continue once daily dosing and complete the corresponding inspection, observation and blood sampling. They continue hospitalization and are discharged on day 17 (D17) after completing the relevant examinations. On days 19, 21, 23，25 (D19, D21，D23 and D25), blood samples are collected and safety evaluation is performed.

Telephone follow-up is performed on day 44 (D44, 30 days after the last dose of the drug).

Subjects who early terminated the test after taking the study drug should be tested at the end of the study (D25/ET) as far as possible.

Blood samples for pharmacokinetic evaluation are collected before daily dosing; D1 (before dosing, and 1, 2, 3, 4, 5, 6, 8, 12 hours after dosing), D2 (before dosing and 24 hours after first dosing), D10 (before dosing), D11 (before dosing), D12 (before dosing), D13 (before dosing), D14 (before dosing, and 1, 2, 3, 4, 5, 6, 8, 12 hours after dosing), D15 (24 hours after last dosing), D16 (48 hours after last dosing), D17 (72 hours after last dosing), D18 (96 hours after last dosing), D19 (120 hours after last dosing), D21 (168 hours after last dosing),D23 (216 hours after last dosing), D25 (264 hours after last dosing). 31 Blood samples collecting points in total.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Brexpiprazole in people with Healthy, run by Otsuka Beijing Research Institute 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 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 1 Nov 2023. 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?

Steady-state peak time (Tss_max) (time frame: Day1, Day2, Day10, Day11, Day12, Day13, Day14, Day15, Day16, Dv17, Day18, Day19, Dv21,Day23, Day25). The study lists 9 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 NCT03734302.

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 1 Nov 2023; AzTrials last refreshed its copy on 8 Nov 2026.
