|Condition or disease||Intervention/treatment||Phase|
|Bipolar I||Drug: Aripiprazole||Phase 3|
This will be an open-label, uncontrolled study which will enroll subjects completing Study 31-08-250 and new subjects. The treatment history of subjects prior to enrollment in the open-label study will vary according to the design of the pivotal double-blind study (i.e 31-08-250).
This open-label study will be comprised of phases similar to the pivotal double-blind study (i.e. Study 250): a screening phase (if applicable), a conversion phase (Phase A, if applicable), an oral stabilization phase (Phase B, if applicable), and an IM depot open-label maintenance phase (Phase C). Phase C will be a minimum of 28 weeks up to a 52-week treatment period with a 4 week follow up period.
During Phase C (the open-label maintenance phase) rescue medication will be allowed for subjects who do not meet stability criteria. This analysis focuses on Phase C due to ClinicalTrials.gov system limitations.

Aripiprazole, Intramuscular (IM) Depot
400mg or 300mg, intramuscular injections every 4 weeks.
- Number of Participants With Adverse Events [ Time Frame: Up to Week 52 ]An adverse event (AE) is defined as any untoward medical occurrence in a patient or participant enrolled in the clinical trial and which does not necessarily have to have a causal relationship with the investigational medicinal product (IMP). AEs were assessed as a criteria for safety and tolerability.
- Injection Site Pain Measured by the Visual Analog Scale (VAS) [ Time Frame: Up to Week 52 ]Injection-site pain was evaluated by mean visual analog scale (VAS) scores as reported by the participant after each injection at visits where an injection occurred. Ratings ranged from 0 (no pain) to 100 (unbearably painful).
- Number of Participants With Clinically Significant Abnormal Laboratory Test Results [ Time Frame: Up to Week 52 ]Standard safety variables to be analyzed included clinical laboratory tests. Incidence of treatment emergent adverse events (TEAEs) of potential clinical relevance included abnormal values in serum chemistry, hematology, urinalysis, and other laboratory test that were identified based on pre-defined criteria. Abnormal laboratory values in participants were reported as serious adverse event/adverse events (SAE/AEs) and are reported in the SAE/other AE section of this report.
- Number of Participants With Clinically Significant Abnormal Vital Signs [ Time Frame: Up to Week 52 ]TEAEs of potential clinical relevance included abnormal values in body weight, systolic and diastolic blood pressure, heart rate, and body temperature that were identified based on pre-defined criteria. Abnormal laboratory values in participants were reported as SAE/AEs and are reported in the SAE/other AE section of this report.
- Number of Participants With Clinically Significant Abnormal Electrocardiogram (ECGs) [ Time Frame: Up to Week 52 ]Twelve-lead ECGs were recorded at specified visits. For each time point, three 12-lead ECG recordings were obtained approximately 5 minutes apart. Additional 12-lead ECGs were permitted to be obtained at the investigator's discretion and were to always be obtained in the event of an early termination. The ECGs were evaluated at the investigational site to determine the participant's eligibility and to monitor safety during the trial.
- Extrapyramidal Symptoms Will be Assessed by Mean Change From Baseline on Abnormal Involuntary Movement Scale(AIMS), Simpson-Angus Scale (SAS), Drug-Induced Extrapyramidal Symptoms Scale (DIEPSS Only Used in Japan) and Barnes Akathisia Rating Scale (BARS) [ Time Frame: Baseline, Week 28, and Week 52 ]AIMS: 10 items described dyskinesia signs; 0-absence/no awareness; 4-severe condition/severe distress. Total score for Items 1-10 ranges from 0 to 40; a higher score reflects severe condition. SAS:Consisted of 10 parkinsonism signs;1-no symptoms;5-severe.Total score for Items 1-10 ranges from 1 to 50;a higher score reflects severe condition.DIEPSS:A 9-item rating scale (8 assessed individual symptoms [4 categories of parkinsonism, akathisia, dystonia & dyskinesia]+1 assessed general severity) was used;0-no symptoms/normal, 4-severe.Total score (8 individual symptom items) was in range of 0 to 32 (a higher score reflects severe condition).BARS:Consisted of 4 items related to akathisia:objective observation, subjective feelings of restlessness, distress, global clinical evaluation.Only BARS global clinical assessment score has been presented and rated using scale:0-absence of symptoms;5-severe akathisia.Total BARS global score ranges from 0 to 5,a higher score reflects severe condition.
- Number of Participants Experiencing Suicidal Events and Their Classification According to the Completion of Columbia Suicide Severity Rating Scale (C-SSRS) [ Time Frame: Up to Week 52 ]Suicidality was monitored throughout the trial using the C-SSRS at every visit. The C-SSRS scale consisted of a screening/baseline evaluation that assessed the participant's lifetime experience and experience over the last 90 days with suicide events and suicidal ideation and a post-baseline/ "Since Last Visit" evaluation that focused on suicidality since the last trial visit.
- Number of Participants With Injection Site Evaluations (Pain, Redness, Swelling, Induration) Measured by Investigator Rating [ Time Frame: Up to Week 52 ]Injection-site reactions were assessed by the investigator (or qualified designee) and the participant. Investigators rated localized pain, redness, swelling, and induration at the most recent injection site using a 4-point categorical scale (absent, mild, moderate, severe) . The participant indicated the degree of pain at the most recent injection site using a VAS. Ratings ranged from 0 (no pain) to 100 (unbearably painful). Ratings included were: 0 = absent, 1 = mild, 2 = moderate, 3 = severe. These assessments occurred at trial visits where injections occurred (scheduled and unscheduled), beginning with the first dose of open-label aripiprazole IM depot administered at the final visit of the Oral Stabilization Phase and continued through the last injection prior to the end of the IM Depot Maintenance Phase/Early termination (ET) visit (ie, evaluations were not done at end of the IM Depot Maintenance Phase/ET visit).
- Percentage of Participants Who Remained Stable at End of Treatment in Phase C [ Time Frame: Up to Week 52 ]The secondary objective was to evaluate the efficacy, as measured by the percentage of stable participants at baseline who remained stable at the end of treatment in the IM depot maintenance phase, of aripiprazole IM depot administered every 4 weeks for up to 52 weeks to subjects with bipolar I disorder.
