  39. Part B: Change from Baseline in Subjective Well-being under Neuroleptic Treatment-Short Form (SWNS) Score

    The subject's feeling of their own well-being will be assessed using the 20 question SWN-S. The questionnaire consists of 20 items and 5 subscales (mental functioning, social integration, emotional regulation, physical functioning, self-control) whose items follow in random order. For items marked with a '+', response choices and scoring are as follows: not at all = 1, hardly at all = 2, a little = 3, somewhat = 4, much = 5, very much = 6. For items marked with a '-', the scoring is reversed; response choices and scoring are as follows: not at all = 6, hardly at all = 5, a little = 4, somewhat = 3, much = 2, very much = 1.

    Measured: Baseline to End of Trial (Maximum 57 Days from First Dose)

  46. Part A - Single Dose: Change from Baseline in Clinical Global Impression-Bipolar Version (CGI-BP) Score

    Severity of illness will be measured using the CGI-BP score. To assess CGI-S, the investigator will answer the following question: "Considering your total clinical experience with this particular population, how mentally ill is the subject at this time?" Response choices include: 0 = not assessed; 1 = normal, not ill at all; 2 = borderline mentally ill; 3 = mildly ill; 4 = moderately ill; 5 = markedly ill; 6 = severely ill; and 7 = among the most extremely ill subjects. This analysis will include participants with bipolar only.

    Measured: Baseline to End of Trial (Maximum 126 Days from First Dose)

  47. Part A - Multiple Dose: Change from Baseline in Clinical Global Impression-Bipolar Version (CGI-BP) Score

    Severity of illness will be measured using the CGI-BP score. To assess CGI-S, the investigator will answer the following question: "Considering your total clinical experience with this particular population, how mentally ill is the subject at this time?" Response choices include: 0 = not assessed; 1 = normal, not ill at all; 2 = borderline mentally ill; 3 = mildly ill; 4 = moderately ill; 5 = markedly ill; 6 = severely ill; and 7 = among the most extremely ill subjects. This analysis will include participants with bipolar only.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Aripiprazole in people with Schizophrenia and Bipolar I Disorder, run by Otsuka Pharmaceutical Development & Commercialization, Inc. at 4 sites in United States.

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 4 inclusion and 14 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 2 Sep 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in United States. 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?

Part A - Single Dose Group: Maximum Observed Plasma Concentration (Cmax) for Aripiprazole and Dehydro-Aripiprazole (time frame: Day 1 to Day 126). The study lists 31 primary outcomes in all. 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 2 Sep 2020; AzTrials last refreshed its copy on 7 Nov 2026.
