PillSense System for Detecting UGI Bleed

This is a prospective, non-randomized, open-label clinical investigation to evaluate feasibility, effectiveness and safety of the PillSense System, the transit of the PillSense Capsule through the GI tract, patient tolerability of the PillSense Capsule, and blood detection.

About this study

Patient eligibility as set out in the inclusion/exclusion criteria for the clinical investigation will be reviewed prior to study enrollment. Prior to administering the PillSense Capsule, the PillSense Receiver will be paired with the PillSense Capsule. The PillSense Receiver collects and displays real-time information gathered by the PillSense Capsule. The PillSense Receiver interprets the data and displays a result message "Blood detected" or "No Blood detected". The overall investigation from the PillSense Capsule activation and ingestion until the result message is displayed takes less than 10 minutes. Esophagogastroduodenoscopy (EGD) should be completed immediately or up to 4 hours after PillSense Capsule administration in each patient that receives a "Blood detected" or "No blood detected" result to confirm the result achieved with the PillSense System. The endoscopy will be conducted according to the site's standard of care. Prior to discharge each patient will undergo an X-Ray examination to evaluate for PillSense Capsule presence. Following discharge, if there is no verifiable evidence that the PillSense Capsule passed through the gastrointestinal tract (GIT) (such as a photograph of stool with capsule in it or photograph of the capsule alone), the patient may undergo an X-Ray examination at Day 7 ± 5 days and, if necessary, at Day 14± 7 days to ascertain the passage status of the PillSense Capsule. If the PillSense Capsule did not pass through the GIT, it should be removed by an endoscopic method.

Treatment and study plan

PillSense

Diagnostic Test

The PillSense System is intended to detect the presence of blood in the stomach for the evaluation of upper gastrointestinal bleeding.

Primary outcomes

  1. Sensitivity

    Time frame: Day 1

    To assess the sensitivity of the PillSense System in detecting the presence of blood in the stomach. The investigational device returns a result of either "Blood detected" or "No blood detected". Sensitivity = True Positives / (True Positives + False Negative). True positives were observations of bleed detected via PillSense capsule confirmed via esophagogastroduodenoscopy (EGD)]. False negatives were observation of bleed not detected via capsule but EGD confirmed bleed.

  2. Specificity

    Time frame: Day 1

    To evaluate the specificity of the PillSense System in detecting the presence of blood in the stomach. The investigational device returns a result of either "Blood detected" or "No blood detected". Specificity=True Negatives / (True Negatives + False Positive). True negatives were observations of no bleed detected via PillSense capsule confirmed via esophagogastroduodenoscopy (EGD)]. False positives were observation of bleed detected via capsule but EGD confirmed no bleed.

Secondary outcomes

  1. NPV

    Time frame: Day 1

    Negative predictive value (NPV) for the PillSense System in detecting the presence of blood in the stomach. The investigational device returns a result of either "Blood detected" or "No blood detected".

  2. Transit

    Time frame: Day 1 through Day 14

    To evaluate the transit of the PillSense Capsule through the GI tract. Passage of the capsule will be monitored until capsule has passed from the body. If subject or study team is unable to determine capsule passage visually, a confirmation x-ray or other imaging will be used to determine if the capsule is still present in the body.

  3. PPV

    Time frame: Day 1

    Positive predictive value (PPV) for the PillSense System in detecting the presence of blood in the stomach. The investigational device returns a result of either "Blood detected" or "No blood detected".
