Primary Outcome Measures:
  • Pharmacokinetic [ Time Frame: six months ] [ Designated as safety issue: No ]
    PK: Relative bioavailability of aripiprazole IM depot injected in the deltoid muscle compared to the gluteal muscle (Frel) based on aripiprazole Cmax, AUCt and AUC∞ PK parameters. Predose, 4hr, 8hr, and 12hr post dose. Days 2,3,5,7,9,11,13,15,17,19,21,25,28,35,42,49,56,63,70,77,84,98,112, and 126/ET.

Secondary Outcome Measures:
  • Columbia-Suicide Severity Rating Scale (C-SSRS) [ Time Frame: six months ] [ Designated as safety issue: No ]
    Incidence of Suicidality

  • Incidence of Treatment-emergent Adverse Events [ Time Frame: six months ] [ Designated as safety issue: No ]
    to determine safety and tolerability of a single dose

  • Laboratory Values of Potential Clinical Relevance [ Time Frame: six months ] [ Designated as safety issue: No ]
    Mean Change from Baseline

  • Vital Signs of Potential Clinical Relevance [ Time Frame: six months ] [ Designated as safety issue: No ]
    Mean Change from Baseline

  • ECG Measurements of Potential Clinical Relevance [ Time Frame: six months ] [ Designated as safety issue: No ]
    mean change from baseline

  • Visual Analog Scale (VAS) Score for Subject [ Time Frame: six months ] [ Designated as safety issue: No ]
    reported Rating of Pain at Most Recent Injection

Enrollment: 37

Primary Completion Date: April 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Deltoid
Deltoid injection site
Drug: Aripiprazole IM Depot
One injection of 400 mg aripiprazole IM depot
Other Name: Abilify
Experimental: Gluteal
Gluteal injection site
Drug: Aripiprazole IM Depot
One injection of 400 mg aripiprazole IM depot
Other Name: Abilify

Detailed Description:

Extended-release gluteal intramuscular (IM) injection of aripiprazole has been tested in subjects with schizophrenia for safety and tolerability. This study will compare the gluteal IM aripiprazole injection with deltoid IM aripiprazole injection for safety and tolerability.


Ages Eligible for Study:   18 Years to 64 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Diagnosis of schizophrenia
  • Stabilized on oral antipsychotic medication
  • Good physical health
  • BMI 18 to 35 kg/m2
  • Prior history of tolerating aripiprazole

Exclusion Criteria:

  • Sexually active males who will not commit to utilizing 2 of the approved birth control methods or who will not remain abstinent during the trial and for 180 days following the last dose of trial medication, or have not had an orchidectomy or sexually active females of childbearing potential who will not commit to utilizing 2 of the approved birth control methods or who will not remain abstinent during the trial and for 150 days following the last dose of trial medication. Abstinence will be permitted if it is confirmed and documented at every trial visit. If employing birth control, 2 of the following precautions must be used: vasectomy, tubal ligation, vaginal diaphragm, intrauterine device, birth control pill, birth control depot injections, implant, condom or sponge with spermicide.
  • Subjects who have met DSM-IV-TR criteria for substance abuse or dependence within the past 180 days; including alcohol and benzodiazepines, but excluding caffeine and nicotine.
  • Subjects with a positive drug screen for cocaine or other drugs of abuse (excluding stimulants and other prescribed medications and marijuana).
  • Use of any psychotropic medications other than their current antipsychotic medication.
  • Use of any CYP2D6 and CYP3A4 inhibitors, or CYP3A4 inducers within 14 days (fluoxetine 28 days) prior to dosing and for the duration of the trial.
  • Females who are pregnant or lactating.
  • Subjects who had participated in a previous IM depot trial within the last one year; or who had previously enrolled and received trial medication in an aripiprazole IM depot clinical trial.
  • Any major surgery within 30 days prior to enrollment.
  • Evidence of organ dysfunction or any clinically significant deviation from normal in physical, electrocardiographic, or clinical laboratory examinations.
  • Subjects who have a significant risk of committing suicide based on history, routine psychiatric status examination, investigator's judgment, or who have an answer of "yes" on questions 4 or 5 (current or over the last 30 days) on the Baseline/Screening version of the Columbia Suicide Severity Rating Scale (C-SSRS).
  • Subjects currently in an acute relapse of schizophrenia.
  • Subjects with a current DSM-IV-TR diagnosis other than schizophrenia, including schizoaffective disorder, major depressive disorder, bipolar disorder, delirium, dementia, amnestic or other cognitive disorders. Also, subjects with borderline, paranoid, histrionic, schizotypal, schizoid or antisocial personality disorder.
  • Subjects who were considered treatment-resistant to antipsychotic medication.
  • Subjects who have had electroconvulsive therapy within 2 months of administration of trial drug.
  • Subjects with a history of neuroleptic malignant syndrome or clinically significant tardive dyskinesia as assessed by the investigator.
  • Any other sound medical reason not to be entered into the trial, as determined by the clinical investigator.
  • Subjects who are known to be allergic, intolerant, or unresponsive to prior treatment with aripiprazole or other quinolinones.
