Participant gender:
All
Summary
We recruited 50 consenting adult subjects with DSM-IV TR diagnoses of bipolar disorder who were about to initiate or switch their current antipsychotic agent. Only 48 patients (23 in the risperidone LAI group and 25 in the oral AAP group) contributed data to the assessments. Patients were titrated and cross-tapered during a 3 month titration and stabilization phase. They were followed for an additional 12 months. Clinical outcomes such as study drop out, adverse events, worsening of symptoms, crisis interventions, need for additional medication, hospitalizations etc. were evaluated from months 3 to 15. The numbers of clinical events (pooled) will be used to evaluate if the long acting injectable form of risperidone has an advantage over the oral second generation antipsychotic agents in terms of treatment continuity and clinical stability.

Criteria
Inclusion Criteria:

- DSM-IV - TR diagnoses of bipolar disorder (I or II or NOS).

- Age 18 to 70 years

- Men or women

- Any Ethnicity

- Currently receiving or willing to receive treatment at sites associated with the
Western Psychiatric Institute and Clinic -University of Pittsburgh Medical Center
(inpatient or ambulatory) or Mon Yough Community Services, Inc. or at Mayview State
Hospital, Bridgeville, PA (inpatient)

- Able to provide competent and sign an informed consent document

- It is clinically appropriate in the eligible individual to consider antipsychotic
treatment for at least 15 months (clinician and investigator determined)

- It is clinically appropriate to switch antipsychotic treatment to one of the second
generation antipsychotic agents being evaluated in this study.

- There is no known contraindication for the use of either risperidone or for more than
two of the antipsychotic agents being considered in the study (Investigator
determined)

- At entry (at the screening visit, and just prior to randomization) Y-MRS (Young-Mania
rating scale, Young et al., 1978) total score > 15 in bipolar disorder patients
entering in a manic or mixed or hypomanic or NOS episode.

- Either life-time or current comorbid substance abuse or dependence is permitted
(unless the Investigator and referring physician opines the substance abuse is likely
to significantly interfere with either the diagnosis of the Axis I condition or to
compromise patients safety due to withdrawal issues (Investigator determined).

- Screening physical and laboratory/EKG procedures are within acceptable limits

Exclusion Criteria:

- Actively suicidal or dangerous to others (Investigator opines that it is inappropriate
to involve the potential subject in the study)

- Pregnant or lactating women

- Women in the reproductive age group who are not using any acceptable contraception
(abstinence is not acceptable) or intend to become pregnant during the trial

- Subjects who are likely to face incarceration during the study duration (and for those
already in the study, the continued participation of such subjects will be evaluated
on a case-by-case basis)

- Patients currently receiving clozapine (or within six weeks prior to randomization)
are ineligible for the study

- Subjects currently receiving a depot neuroleptic injectable agent, or within 2
injection cycles of receiving the injection prior to randomization.

- Allergy or serious side effects (for instance - neuroleptic malignant syndrome) to
either risperidone or to more than two of the other second-generation antipsychotic
agents that have been approved for use in the U.S.A. (olanzapine, quetiapine,
ziprasidone, aripiprazole-per investigator and referring clinician).

- Treatment resistance to either risperidone, or to more than two of the other
antipsychotic agents in this trial (olanzapine, quetiapine, ziprasidone,
aripiprazole).

- This is the first episode of mania, mixed or hypomania for patients.

- Current (or within one month prior to randomization) participation in an
investigational drug/device study.

- Currently participating in another study that would confound the present study
objectives (per investigator)
