Study summary

It has been demonstrated that the VIPUN Gastric Monitoring System (GMS) can discriminate healthy physiological and pharmacologically-inhibited gastric motility, using a codeine-model in healthy adults (S60320 / AFMPS80M0687).

Erythromycin is a gastroprokinetic agent, known to stimulate gastric contractility. A single dose of 200 mg erythromycin has been shown to induce a prolonged period of enhanced phasic contractile activity.

The primary aim of this investigation is to validate the ability of the VIPUN GMS to discriminate between normal and pharmacologically-enhanced fasting gastric motility in healthy adults.

The performance of the VIPUN GMS can be enhanced by data-driven optimization of the VIPUN Motility Algorithm, used to quantify gastric motility.

Study arms

  • Experimental
    VIPUN GMS

    Single arm study.

    Device: VIPUN GMS · Drug: Erythromycin Lactobionate

Interventions

  • DeviceVIPUN GMS

    Motility is measured for 4 hours with the VIPUN Gastric Monitoring System (GMS).

  • DrugErythromycin Lactobionate

    Test model: Erythromycin has gastroprokinetic properties. The primary aim of this investigation is to validate the ability of the VIPUN GMS to discriminate between normal and pharmacologically-enhanced fasting gastric motility in healthy adults. Erythromycin Lactobionate infusion: 200 mg i.v. infusion over a period of 20 minutes. Note: Erythromycin is not labeled as a gastroprokinetic agent in Belgium.

What researchers measure

Primary outcomes

  1. GBMI baseline

    Gastric Balloon Motility Index (GBMI) is measured with the VIPUN Gastric Monitoring System. GBMI is a value between 0 and 1.

    Time frame: t = 0 - 119 minutes

  2. GBMI120 - 139

    Motility during erythromycin administration. Gastric Balloon Motility Index (GBMI) is measured with the VIPUN Gastric Monitoring System. GBMI is a value between 0 and 1.

    Time frame: t = 120 - 139 minutes

Secondary outcomes

  1. GBMI140-240

    Motility in the period 140 - 240 minutes. Gastric Balloon Motility Index (GBMI) is measured with the VIPUN Gastric Monitoring System. GBMI is a value between 0 and 1.

    Time frame: t = 140 - 240 minutes

  2. Symptoms

    Epigastric symptoms (nausea, bloating, pain) are surveyed with Visual Analogue Scales for severity of each individual symptom (100 mm, 0 = Absent to 100 mm = worst possible sensation) at a 15 minute interval.

    Time frame: t = 0 - 240 minutes

  3. Incidence of adverse events

    Incidence of adverse events

    Time frame: t = 0 - 240 minutes

  4. Severity of adverse (device) events/effects

    Severity of adverse (device) events/effects

    Time frame: t = 0 - 240 minutes

  5. Seriousness of adverse (device) events/effects

    Seriousness of adverse (device) events/effects

    Time frame: t = 0 - 240 minutes

  6. Relatedness of adverse (device) events/effects

    Relatedness of adverse (device) events/effects

    Time frame: t = 0 - 240 minutes

  7. Incidence of device deficiencies of the investigational medical device

    Qualitative description of the event, onset, duration, origin, action taken and outcome of the event

    Time frame: t = 0 - 240 minutes

  8. Incidence of protocol deviations related to the investigational medical device

    Qualitative description of the event, onset, duration, origin, action taken and outcome of the event

    Time frame: t = 0 - 240 minutes
