A Trial to Explore Acceptance and Performance of Using a Digital Medicine System With Healthcare Professionals and Adults With Schizophrenia, Schizoaffective Disorder, or First Episode Psychosis on an Oral Atypical Antipsychotic

July 2, 2020 updated by: Otsuka Pharmaceutical Development & Commercialization, Inc.

A Multicentre, 8-week, Single-arm, Open-label, Pragmatic Trial to Explore Acceptance and Performance of Using a Digital Medicine System With Healthcare Professionals and Adult Subjects With Schizophrenia, Schizoaffective Disorder, or First Episode Psychosis on an Oral Atypical Antipsychotic (Aripiprazole, Olanzapine, Quetiapine, or Risperidone)

Digital medicine systems (DMS) have been designed to assist individuals with the management of their daily health, wellness, and medication use. The DMS is being developed as a healthcare management tool to precisely measure medication adherence and to potentially enhance adherence.

Detailed Description

The advancements in the treatment of mental health patients with DMS will enable healthcare professionals to assess suboptimal adherence and make more informed treatment decisions. In addition to these improvements, it will also provide a platform for engagement between participants, healthcare professionals, and caregivers/support persons.

Participants who entered the trial were treated with one of the oral atypical antipsychotics defined in the trial (aripiprazole, olanzapine, quetiapine, or risperidone [though no participant took risperidone in this trial]). The treatment medication decision was determined by the healthcare professionals.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
EXPERIMENTAL: Aripiprazole
Participants received 1 oral tablet of CoEncapsulated (CoE) aripiprazole, wearing the DMS patch, and using the associated smartphone app for a total of 8 weeks.
Device: Digital Medicine System
DMS components: a CoE product consisting of an approved antipsychotic medicinal product co-encapsulated with Conformité Européenne (CE)-marked miniature ingestible event marker in tablet; a CE-marked compatible medical device (a Proteus Patch [Disposable Wearable Sensor Version 5]); proprietary medical software (a local and remote computing application).
Drug: Aripiprazole
Dosage determined by the healthcare professionals.
EXPERIMENTAL: Olanzapine
Participants received 1 oral tablet of CoE olanzapine, wearing the DMS patch, and using the associated smartphone app for a total of 8 weeks.
Device: Digital Medicine System
DMS components: a CoE product consisting of an approved antipsychotic medicinal product co-encapsulated with Conformité Européenne (CE)-marked miniature ingestible event marker in tablet; a CE-marked compatible medical device (a Proteus Patch [Disposable Wearable Sensor Version 5]); proprietary medical software (a local and remote computing application).
Drug: Olanzapine
Dosage determined by the healthcare professionals.
EXPERIMENTAL: Quetiapine
Participants received 1 oral tablet of CoE quetiapine, wearing the DMS patch, and using the associated smartphone app for a total of 8 weeks.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage Of Days With Good Patch Coverage
Time Frame: Up to 8 weeks
The DMS includes a drug-device combination of a CoE product, a wearable sensor patch, and application software (smartphone) to record activity and rest and mark events through the act of ingestion. The CoE product consists of an approved antipsychotic medication enclosed with an Ingestible Sensor Pill (miniature ingestible event marker in tablet [MIT]). The sensor patch detects and records each MIT ingestion, as well as other physiologic and behavioral data. Good patch coverage for a specific day was defined as having either at least 80% patch data available (80% of the day the patch was worn and data was collected as noted via the accelerometer channel) or the MIT was detected within the 24-hour period, for each day while the participant was in the trial. The percentage of days was calculated as the number of days with good patch coverage divided by the total number of trial days for each participant. Descriptive statistics were performed for this outcome measure.
Up to 8 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Participant Adherence
Time Frame: Up to 8 weeks
The DMS includes a drug-device combination of a CoE product, a wearable sensor patch, and application software (smartphone) to record activity and rest and mark events through the act of ingestion. The CoE product consists of an approved antipsychotic medication enclosed with an Ingestible Sensor Pill (MIT). The sensor patch detects and records each MIT ingestion, as well as other physiologic and behavioral data. Participant adherence was measured as the detected MITs over the expected MITs ingested during the trial days with good patch coverage. The more the participant successfully engaged in a number of processes across the 8-week trial, the greater the measured adherence. Descriptive statistics were performed for this outcome measure.
Up to 8 weeks
