Study summary

The primary purpose of the study is to evaluate the positive detection accuracy (PDA) and detection latency measures of the D-Tect patch.

Read the detailed description

This is an open-label study to determine the accuracy of ingestible event marker (IEM) detection and detection latency of the D-Tect patch by completing a series of patch applications and IEM ingestions in the clinic.

The participants were enrolled in two cohorts within this study- Cohort 1: healthy participants received the placebo-embedded IEM tablets, Cohort 2: participants with serious mental illness (SMI) i.e schizophrenia, major depressive disorder, or bipolar I disorder received Abilify MyCite® tablets (aripiprazole-embedded IEM tablets).

This single-center trial was conducted in the United States. The overall time to participate in this study is up to approximately 17 days.

Eligibility criteria

Inclusion Criteria for Cohort 1:

  • In good general health or medically stable.
  • Is able and willing to participate in, and adhere to, all testing procedures, both onsite and offsite, for the entire testing.
  • The participant has access to a telephone for communicating with the trial personnel and for trial personnel to contact the participant.

Inclusion Criteria for Cohort 2:

  • In good general health or medically stable.
  • Has confirmed diagnosis of schizophrenia, major depressive disorder, or bipolar I disorder per Diagnostic and Statistical Manual of Mental Disorders - 5th Edition (DSM-5) criteria and currently prescribed and taking aripiprazole.
  • Is able and willing to participate in, and adhere to, all testing procedures, both onsite and offsite, for the entire testing.
  • Participant has access to a telephone for communicating with the trial personnel and for trial personnel to contact the participant

Exclusion Criteria for Cohort 1 and 2:

  • Any medical condition, treatment, or symptoms that, in the judgment of the trial clinician, could place the participant at more than the minimal risk from involvement in the testing.
  • Hospitalization, emergency room visit, surgery or new medical treatment within 30 days before testing begins or planned during testing.
  • Difficulty with or inability to swallow tablets.
  • Active skin infection or active dermatitis, or history of chronic inflammatory skin condition including psoriasis and chronic dermatitis (except atopic dermatitis).
  • The investigator will determine if any participant should be excluded from the trial based on history of, or current, alcohol abuse, drug abuse or use of illegal drugs (e.g., amphetamines or heroin).
  • Allergy to adhesive bandages/tapes (e.g., Band-Aids®) or latex.
  • Positive urine pregnancy test at screening visit (dipstick).
  • Participant is taking any concomitant medication that places the participant at a greater risk for skin reactions or skin sensitivity.

Study arms

  • Experimental
    D-Tect Patch

    A D-Tect patch was applied by the clinical staff prior to each IEM tablet ingestion, and directly observed ingestions (DOIs), followed by ingestion of 15 placebo-embedded IEM tablets, 1 every 15 minutes in Cohort 1 on Day 1 and a single dose of Abilify MyCite® tablet in Cohort 2 on Day 1.

    Drug: Placebo IEM tablet · Drug: Abilify MyCite® · Device: D-Tect Patch

Interventions

  • DrugPlacebo IEM tablet

    Oral placebo-embedded IEM tablet.

  • DrugAbilify MyCite®

    Oral aripiprazole-embedded IEM tablet.

    Also known as: OPC-14597 Digital

  • DeviceD-Tect Patch

    The D-Tect patch is a wearable sensor (WS) capable of detecting the ingestion of the IEM and measuring physiologic parameters. The WS automatically logs and stores the time when the IEM reaches the stomach and transmits the data to a smartphone.

What researchers measure

Primary outcomes

  1. Cohort 1: Positive Detection Accuracy (PDA) of D-Tect Patch

    The PDA is calculated as the number of total positive detections by patch divided by the number of the total DOIs. PDA was estimated by Clopper-Pearson method.

    Time frame: At Day 1

  2. Cohort 1 and 2: Patch Detection Latency Period

    The patch detection latency period is defined as the time between the ingestion of the tablet and the detection of the tablet ingestion by the patch. Kaplan Meier estimation was used to measure the patch detection latency period.

    Time frame: At Day 1

  3. Cohort 1 and 2: Ingestion Data Transfer Latency Period

    The ingestion data transfer latency period is measured as the time between the detection of the tablet ingestion by the patch and the display of ingestion data on the mobile device. Kaplan Meier estimation was used to measure the ingestion data transfer latency period.

    Time frame: At Day 1

  4. Cohort 1 and 2: Total Detection Latency Period

    The total detection latency is measured as the total time between the ingestion of the tablet and the display of ingestion data on the mobile device. Kaplan Meier estimation was used to measure the total detection the latency period.

    Time frame: At Day 1

Secondary outcomes

  1. Number of Participants With Treatment-Emergent Adverse Events (TEAEs), Device-related TEAEs, Serious TEAEs (SAEs), TEAEs Leading to Study Discontinuation

    TEAEs were defined as AEs that occurred on or after the participant wears any patch or takes any tablet from the study at test day, and the AEs that occurred before the participant wears any patch or takes any tablet and are worsening, serious, related, or resulted in death, discontinuation, or interruption of investigational product. A serious TEAE was defined as a TEAE that is fatal, life-threatening, results in persistent or significant disability/incapacity, constitutes a congenital anomaly/birth defect, or requires inpatient hospitalization or prolongation of existing hospitalization.

    Time frame: From Day 1 up to follow-up (up to Day 10)
