Apollo Endosurgery, Inc., a leader in minimally invasive endoscopic surgical products for bariatric and gastrointestinal procedures, announced the presentation of results from the ORBERA Pivotal Trial at this year’s Digestive Disease Week (DDW) conference. The study showed that ORBERA Intragastric Balloon users lost significantly more weight than the control group, leading to significant improvement in weight related quality of life and improved eating behaviors.


“At the completion of the study, it was clear that the ORBERA Intragastric Balloon produced significant weight loss and quality of life benefits, when compared to the study’s control group,” said Dr. Barham Abu Dayyeh, Gastroenterologist and Advanced Endoscopist at The Mayo Clinic. “The results of this study prove that ORBERA can be an outstanding tool to aid weight loss and support sustainable, healthy habits, even after it has been removed.”

In the US pivotal ORBERA clinical trial, a multicenter, prospective, randomized, non-blinded comparative study, obese patients with a BMI between 30 and 40 were randomized to treatment or control in a 1:1 ratio. The treatment group underwent placement of the ORBERA balloon followed by removal after 6 months. They concurrently participated in a 12-month behavioral modification program. The control group participated in the 12-month behavioral modification program alone. For patients in the treatment group, the device was removed at month 6, with regular office visits continuing through 1 year.

A total of 125 patients were randomized to the treatment group and 130 patients were randomized to the control group. More than three-fourths (78.4 percent, 98/125) of the treatment group and 71.5 percent (93/130) of the control group completed the full study at Week 52.

Detailed findings from the trial include:

  • At month six, the ORBERA group achieved a mean of 40 percent Excess Weight Loss (EWL), with 72 percent of ORBERA-treated patients achieving at least 25 percent EWL
  • Mean Total Body Weight Loss (TBWL) at six months was 10.54 percent for the treatment group compared to 4.71 percent TBWL for the control group.
  • The ORBERA group lost over twice as much weight as the control group at six months.
  • The ORBERA group also lost significantly more weight than the control group over the course of the study, and was able to maintain significant weight loss through month 12, six months after removal of the device.

Practice Pearls:

  • Note that this study was published as an abstract and presented at a conference. These data and conclusions should be considered to be preliminary until published in a peer-reviewed journal.
  • The intervention group had lower rates of diabetes.
  • Subjects should achieve a mean minimum threshold of 25% excess weight loss (EWL) at 12 months.
