Study summary

This study will assess asenapine (Sycrest®) use in participants with bipolar disorder; comparison will be made to the use of risperidone (RISPERDAL®CONSTA®) and olanzapine (Zyprexa®). The occurrence of identified and potential clinically important risks will also be assessed.

Study population

Participants with Bipolar Disorder codes who are included in the United Kingdom Clinical Practice Research Datalink (CPRD) and, if required, The Health Improvement Network (THIN) database.

If pre-specified sample size and exposure criteria are met, secondary objectives will be conducted in 2 separate study populations: 1. Participants treated with asenapine and diagnosed with schizophrenia and no prior and/or concomitant diagnosis of bipolar disorder; 2. Participants treated with asenapine with no prior and/or concomitant diagnoses of bipolar disorder or schizophrenia, but diagnosed with i) Alzheimer's disease, ii) other diagnoses - mental disorders or iii) no diagnosis.

Inclusion criteria

  • A diagnosis of Bipolar Disorder

Exclusion criteria

Exclusion Criteria for the Bipolar Disease Cohort:

  • None

Inclusion Criteria for the potential Schizophrenia Cohort:

What researchers measure

Primary outcomes

  1. Number of Participants with Bipolar Disorder with Identified and Potential Clinically Important Risks

    Identified and potential clinically important risks will include: extrapyramidal symptoms, somnolence and sedation, neuroleptic malignant syndrome, rhabdomyolysis, seizure, hyperprolactinaemia, orthostatic hypotension, neutropenia, allergic reactions, dyslipidaemia and diabetes mellitus with the use of asenapine versus risperidone or olanzapine

    Time frame: Approximately 1 year

Secondary outcomes

  1. Number of Participants with Schizophrenia with Identified and Potential Clinically Important Risks

    When enrollment and participant exposure reaches a level that adequate power (80%) is achieved according to pre-defined power calculations, risk incidence with use of asenapine in participants diagnosed with schizophrenia with no prior and/or concomitant diagnosis of bipolar disorder will be analyzed. Identified and potential clinically important risks will include: extrapyramidal symptoms, somnolence and sedation, neuroleptic malignant syndrome, rhabdomyolysis, seizure, hyperprolactinaemia,orthostatic hypotension, neutropenia, allergic reactions, dyslipidaemia and diabetes mellitus with the use of asenapine versus risperidone or olanzapine

    Time frame: Approximately 1 year

  2. Number of Participants without Diagnoses of Schizophrenia or Bipolar Disorder with Identified and Potential Clinically Important Risks

    When enrollment and participant exposure reaches a level that adequate power (80%) is achieved according to pre-defined power calculations, risk incidence with use of asenapine in participants with no prior and/or concomitant diagnoses of bipolar disorder or schizophrenia, but diagnosed with i) Alzheimer's disease, ii) other diagnoses - mental disorders or iii) no diagnosis, will be analyzed. Identified and potential clinically important risks will include: extrapyramidal symptoms, somnolence and sedation, neuroleptic malignant syndrome, rhabdomyolysis, seizure, hyperprolactinaemia,orthostatic hypotension, neutropenia, allergic reactions, dyslipidaemia and diabetes mellitus with the use of asenapine

    Time frame: Approximately 1 year
