Background and Objectives

Obesity and its related comorbidities are associated with serious health risks. This trial evaluated the safety and effectiveness of the ORBERA® Intragastric Balloon System (IGB) as an adjunct to lifestyle intervention in a post-marketing clinical setting.

Methods and Materials

In this multicenter study, 258 adults with a body mass index of 30–40 kg/m2 were treated with the IGB as an adjunct to weight reduction and followed for up to 12 months. The primary objective was to demonstrate in a post-marketing clinical setting that the incidence of device and procedure-related serious adverse events (SAEs) after 26 weeks of IGB treatment is no greater than 15%.


The incidence of device and procedure-related SAEs was 8.9% with a 1-sided upper limit confidence interval of 12.4%, compared with the 9.6% overall SAE rate seen in the US pivotal study; therefore, the primary safety endpoint was met. The key secondary effectiveness endpoint was also met with a mean maximum %TBWL of 12.5 being achieved at the time of IGB removal (26 weeks).


The post-marketing safety and effectiveness profile of the IGB are consistent with what was observed in the US pivotal study. No new risks were identified.
