  • Body mass index (BMI) between 18 and 35 kg/m^2 at screening
  • Male and female subjects who are surgically sterile, female subjects who have been postmenopausal for at least 12 consecutive months prior to screening or male/female subjects who agree to remain abstinent or practice 2 of the approved birth control methods from screening for at least 150 days after dose of Investigational Medical Product (IMP) for female subjects or 180 days after dose of IMP for male subjects.
  • Documented history of previously tolerating Aripiprazole per investigator's judgment.
Exclusion Criteria

  • Subjects may not receive varenicline beyond the screening visit.
  • Subjects who had participated in any clinical trial involving a psychotropic medication within 1 month prior to administration of IMP
  • Major surgery within 30 days prior to administration of IMP or surgery during the trial
  • Subjects at significant risk of committing suicide based on history, psychiatric exams
  • Subjects currently in an acute relapse of schizophrenia
  • Subjects with a current DSM-5 diagnosis other than schizophrenia
  • Subjects with a history of neuroleptic malignant syndrome, seizure disorder, or clinically significant tardive dyskinesia
  • Subjects who have had electroconvulsive therapy within 2 months prior to administration of IMP
  • Females who are breast-feeding and/or who have a positive pregnancy test result prior to receiving IMP

Primary Outcome Measures
NameTimeMethod
Electrocardiograms (ECGs) [Safety and tolerability]Screening Days -30 to Day 182 post dose/Early Termination

Heart rate, RR, PR, WRS and WT intervals will be monitored to assess the safety and tolerability of the drug.

Vital Signs [safety and tolerability]Screening Days -30 to Day 182 post dose/Early Termination

Systolic/diastolic blood pressure, heart rate and body temperature will be monitored to assess the safety and tolerability of the drug.

Suicidality via Columbia-Suicide Severity Rating Scale (C-SSRS) [safety and tolerability]Screening Days -30 to Day 182 post dose/Early Termination

C-SSRS score will be monitored throughout the trial to assess the safety and tolerability of drug

Clinical Laboratory Tests [safety and tolerability]Screening Days -30 to Day 182 post dose/Early Termination

Hematology, clinical chemistry \& urinalysis tests will be performed to assess the safety and tolerability of drug.

Incidence of Adverse Events (AEs) [safety and tolerability]Screening Days -30 to Day 182 post dose/Early Termination

AEs will be monitored to assess safety and tolerability of drug

Extrapyramidal Symptoms (EPS) Rating ScalesScreening Days -30 to Day 182 post dose/Early Termination

EPS score will be monitored to assess safety and tolerability of drug

Investigator's Assessment of Injection SiteScreening Days -30 to Day 182 post dose/Early Termination

The injection site will be monitored to assess the safety and tolerability of drug

Visual Analog Scale (VAS) Scores for Pain PerceptionDay 1 to Day 28 post dose

VAS score will be monitored to assess safety and tolerability of drug

Secondary Outcome Measures
NameTimeMethod
Pharmacokinetics - Terminal-phase elimination half-life (t1/2,z)Day 1 to Day 182/Early Termination

t1/2,z will be assessed for plasma Aripiprazole and its major metabolite dehydro-aripiprazole to determine drug persistence in the body

Pharmacokinetics - Maximum plasma concentration (Cmax)Day 1 to Day 182/Early Termination

The maximum plasma concentration of drug at injection site will be assessed for plasma Aripiprazole and its major metabolite dehydro-aripiprazole

Pharmacokinetics - time of maximum plasma concentration (tmax)Day 1 to Day 182/Early Termination

The amount of time that the maximum plasma concentration of drug at injection site will be assessed for plasma Aripiprazole and its major metabolite dehydro-aripiprazole

Pharmacokinetics - area under concentration-time curve (AUC) calculated from time zero to time t (AUCt)Day 1 to Day 182/Early Termination

AUCt will be assessed for plasma Aripiprazole and its major metabolite dehydro-aripiprazole to determine average concentration of drug over time

Pharmacokinetics - AUC calculated from time to infinityDay 1 to Day 182/Early Termination

AUCinfinity will be assessed for plasma Aripiprazole and its major metabolite dehydro-aripiprazole to determine total drug exposure over time
