ST. PAUL, Minn., Dec. 15, 2016- EnteroMedics Inc., the developer of medical devices using neuroblocking technology to treat obesity, metabolic diseases and other gastrointestinal disorders, today announced an assessment of real-world, clinical practice weight loss data in patients using the Company's vBloc® Therapy in combination with vBloc® Achieve, which confirms previously reported positive results from the ReCharge Pivotal Trial. These data show similar mean percent total weight loss (TWL) through six (9%) and nine months (10%) as compared to results from the rigorous ReCharge Pivotal Trial (9% at 6 months; 10% at 9 months). The data were collected at vBloc Institutes across the United States. vBloc Institutes are facilities that have integrated vBloc Therapy and vBloc Achieve into their practices.

As previously reported, the ReCharge Pivotal Trial is a randomized, double-blind, sham-controlled, multicenter pivotal clinical trial of vBloc Neurometabolic Therapy in 239 patients with obesity. At 24 months, 76% percent of the randomized vBloc participants (n=123) remained in the trial. The mean excess weight loss (EWL) among vBloc participants who presented for their 24-month visit was 21%, with a mean percent total weight loss (TWL) of 8%. Of the 24 Sham control patients who had not yet crossed over to vBloc at 24 months, the EWL and TWL was 4% and 1%, respectively.

vBloc Therapy works to control sensations of hunger using a pacemaker-like device that is implanted under the skin during a safe, minimally-invasive procedure that does not alter or remove any patient anatomy. This device can be adjusted to optimize patients' therapy needs. Patients feel the sensation of fullness, empowering them to eat less, control their appetite, make healthier choices and lose weight without the major lifestyle implications of traditional weight loss surgeries.
