Brief Summary

This study is a prospective, non-randomized, open-label, single-center study. The aim of this study is to assess the safety of the IGballoon in the human body. The effectiveness of the IGBalloon in relation to weight loss behaviour of the human body will also be investigated. This study will involve 20 participants who will be divided into two groups:

  1. 1.Monitoring group with 5 participants who swallow an IGBalloon. After four weeks, safety will be tested. Up to four additional IGBalloons may be ingested, if necessary, over the following eight weeks.
  2. 2.Treatment group of 15 participants receiving up to 5 IGBalloons over a period of 8 weeks as required. This group will be evaluated for efficiency of the IGBalloon.

IGBalloon treatment

EXPERIMENTAL

20 patients

Device: IGBalloon

Interventions

IGBalloonDEVICE

An initial five participants meeting eligibility requirements will ingest one IGBalloon(IGB), undergo an immediate endoscopy to assess device inflation and condition of the gastric mucosa and will be followed-up at 1, 2, 4, 6 and 8 weeks. At the 2-week follow-up, a second IGB is ingested in the event that there is no decrease in weight or increase in satiety. After 4-weeks, an additional IGB is ingested in the event that there is no decrease in weight and increase in satiety. After 6-weeks, an additional IGB may be ingested in the event that there is no decrease in weight and increase in satiety. After 8-weeks, an additional device (max. of 5) may be ingested in the event that there is no decrease in weight and increase in satiety. The initial 5 sentinel patients will undergo a controlendoscopy. No more than five IGB are ingested. If no significant changes or unanticipated SAEs have occurred in the initial five participants, a further 15 participants will begin the treatment.
