About this trial
This is an interventional treatment trial for Schizophrenia focused on measuring Schizophrenia, Schizoaffective Disorder, Aripiprazole, Olanzapine, Paliperidone, Quetiapine, Risperidone, Liquid Chromatography-Tandem Mass Spectrometry
Eligibility Criteria
Inclusion Criteria:
- Participant has a diagnosis of schizophrenia (Code 295.90) or schizoaffective disorder (Code 295.70) according to Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM 5), based on history and clinical assessment by the investigator
- Participant has current active medication management issues and has experienced a medication treatment modification within the 6 weeks prior to Screening
- Participant is currently taking one or more of the following antipsychotic medications for at least 1 week for oral antipsychotics and at least 1 injection cycle for long-acting injectable (LAI) antipsychotics. In addition, the treating clinician plans to continue the antipsychotic medication(s) for at least 4 weeks subsequent to the Screening visit. Participant may be taking more than one formulation of a particular medication (such as oral and LAI) at or above the minimum dose specified in protocol. Qualifying formulations of the antipsychotic medications are: Aripiprazole (oral formulation only), Olanzapine (oral formulation only), Paliperidone (oral and/or LAI formulations), Quetiapine (oral formulation only), and Risperidone (oral and/or LAI formulations)
- Participant has had no clinically significant suicidal behavior or ideation during the week prior to Screening, according to the investigator's judgment
- Participant is generally healthy and has no clinically significant or unstable medical problems as determined by the investigator, except for the indication for which the antipsychotic treatment is being prescribed. This determination must be recorded in the participant's source documents and initialed by the investigator
Exclusion Criteria:
- Participant has been attending the outpatient psychiatric clinic for more than 12 months since the last psychiatric hospitalization
- During Screening, participant has active alcohol or substance use disorder (except tobacco) of moderate or severe severity according to DSM 5 criteria
- Participant has a history of or currently has a clinically significant (particularly unstable) medical illness, other than the indication for which the participant is taking antipsychotic therapy, that the investigator considers should exclude the participant or that could interfere with the participant completing the study or with interpretation of the study results. Treated, stable, chronic medical problems are allowed, as long as these conditions do not interfere with the study assessments
- Participant is receiving clozapine
- Participant has donated blood or blood products or had substantial loss of blood (ie, blood loss of approximately more than 450 milliliter (mL) or blood loss that required a blood transfusion) within 1 month of Screening or has the intention to donate blood or blood products during the study

Participants will receive treatment as usual (TAU) which include one or more of the 5 antipsychotic medications (aripiprazole, olanzapine, paliperidone, quetiapine, and risperidone) for 12 weeks as determined by the treating clinician and the antipsychotic medication plasma level (AMPL) results will not be available to the clinicians until all participants in this cohort at a given site have completed their study participation.
