Study summary

The ID-Cap System is classified as an ingestion event marker (IEM), a Class II medical device. The system is intended to record time-stamped ingestions with the ingestible sensor, ID-Tag which transmits a signal to a wearable device, the ID-Cap Reader. In this study, 36 subjects will ingest capsules containing ingestible sensors while wearing the Reader and being observed in a clinic setting.

Terms in these criteria, in plain language(6)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Study arms

  • Experimental
    ID-Capsules- Active

    Randomly-assigned ingestions of ID-Capsules containing ingestible sensors (ID-Capsule- Active) while wearing the ID-Cap Reader (Wearable Sensor) under direct observation • Subjects will ingest ID-Capsules containing the ingestible sensor which emits a signal from within the subject's stomach. This signal is detected by the wearable Reader, and the ingestion event is recorded.

    Device: ID-Capsule- Active · Device: Wearable Sensor

  • Placebo comparator
    ID-Capsules- Inactive

    Randomly-assigned ingestions of ID-Capsules containing no ingestible sensors while wearing the ID-Cap Reader under direct observation • Subjects will also ingest empty placebo capsules that do not contain ingestible sensors. In the absence of an ingested sensor, no signal is received by the Reader after the capsule is ingested, and the ingestion event is not recorded.

    Device: Wearable Sensor · Device: Placebo

Interventions

  • DeviceID-Capsule- Active

    A standard gelatin or HPMC capsule with an embedded ingestible wireless sensor.

  • DeviceWearable Sensor

    Subjects will wear an ID-Reader

  • DevicePlacebo

    A standard gelatin or HPMC capsule without an embedded ingestible wireless sensor.

What researchers measure

Primary outcomes

  1. Positive Detection Accuracy (PDA)

    The number of active ingestible sensors detected divided by the number of active ingestible sensors administered under direct observation.

    Time frame: Up to 10 days

  2. Negative Detection Accuracy (NDA)

    The number of inactive empty capsules not detected divided by the number of inactive empty capsules administered under direct observation. Determination of NDA will also include the number of monitoring periods with no ingestion events detected by the Reader divided by the number of specific monitoring periods performed for the purpose of detecting false positives.

    Time frame: Up to 10 days

Secondary outcomes

  1. Number of Study Participants with Adverse Events as a Measure of Safety and Tolerability

    Incidence of mild, moderate, and severe adverse events overall and related to the device; discontinuations due to adverse events

    Time frame: Up to 10 days during ingestion events through the follow-up assessment scheduled within 3 to 5 days of the last ingestion

Other outcomes

  1. Gender/BMI Effects

    Effect of gender/BMI on the positive detection accuracy (covariate analysis) and other device performance measures

    Time frame: Up to 10 Days

  2. Detection time

    Time from ingestion of ID-Capsule to first detection by the ID-Cap Reader

    Time frame: Up to 60 minutes post ingestion

  3. Signal Duration

    Time from first to last detection of the signal from the ingested sensor by the ID-Cap Reader

    Time frame: Up to 90 minutes post ingestion

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Mar 2018 to primary completion in May 2018, 1 month.

Of 442 interventional studies with no phase under Medication Adherence, half reached primary completion within 21 months of starting (the median), counting those still running; a quarter within 11 and three quarters within 41. This study's 1 month is below that.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 11, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
