EnteroMedics Announces Maestro® RC System Updated Weight Loss Data to Be Presented at the American Society for Metabolic and Bariatric Surgery Annual Meeting
Company Also Announces Long-Term, Updated Data From VBLOC-DM2 and EMPOWER Studies
St. Paul, MN - June 14, 2011
EnteroMedics Inc. (NASDAQ: ETRM), the developer of medical devices using neuroblocking technology to treat obesity and other gastrointestinal disorders, today announced that updated weight loss data from clinical studies of the Company's VBLOC® vagal blocking therapy delivered via the Maestro® Rechargeable (RC) System will be presented at the 28th Annual Meeting of the American Society of Metabolic and Bariatric Surgeons (ASMBS), being held June 13-17 in Orlando, FL. The presentation, titled "Vagal Blocking for the Treatment of Obesity Delivered Using the Fully Implantable Maestro Rechargeable System: 12 Month Results," will be delivered by Dr. Lillian Kow, BMBS, PhD, FRACS, on June 17, 2011 at 8:30 AM ET.
Dr. Kow stated: "The Maestro System is the only surgical intervention to demonstrate a prolonged effect on weight loss and obesity related co-morbidities without compromises in safety, lifestyle or anatomy. The data presented at ASMBS support our increasingly well-established understanding of how VBLOC Therapy affects the underlying physiology of obesity and undermines the feelings of hunger or lack of fullness that sustain it. I look forward to longer-term follow up in the DM2 study and to results of the ongoing, larger outcome ReCharge study."
The Company also announced long-term, updated obesity, diabetes and hypertension clinical results, including weight loss, HbA1c and blood pressure data, from its VBLOC-DM2 ENABLE and EMPOWER Studies of the Maestro® System. For all studies of the Maestro® Systems, there remain no reported therapy-related serious adverse events.
Mark B. Knudson, PhD, EnteroMedics' President and Chief Executive Officer, said: "We continue to see clinically meaningful and durable weight loss results, an excellent overall safety profile, significant effects on the co-morbidities of hypertension and diabetes and high levels of patient acceptance with the Maestro System. These outcomes, which come from a broad patient population, support our confidence in the ongoing pivotal ReCharge Trial, which remains on track for completion of enrollment by year-end. We also continue to make progress in our commercial development efforts for the Maestro System in Australia and select European markets."
Updated Maestro® Rechargeable System Data Presented at ASMBS
Updated data presented at ASMBS included combined excess weight loss (EWL) data from two studies of EnteroMedics' second-generation Maestro® RC System: the Company's initial feasibility study in patients with morbid obesity and the VBLOC- DM2 ENABLE study in patients with morbid obesity and Type-2 diabetes mellitus.

Updated EMPOWER Study Results
The EMPOWER study is a randomized, double-blind, controlled pivotal study designed to evaluate the safety and efficacy of the Company's first-generation Maestro® RF System in the treatment of obesity. Unlike the second-generation Maestro® RC System, which is powered by an internal battery recharged via an external mobile charger and transmit coil worn by the patient for a short time each week, the Maestro® RF System is powered by an external controller and transmit coil which must be worn daily by the patient for the hours prescribed to receive therapy.
The Company today announced updated 30 month data on EWL:
| Visit | EWL | N |
|---|
| 6 Months | -17.9% | 271 |
| 12 Months | -16.3% | 265 |
| 18 Months | -17.2% | 188 |
| 24 Months | -19.2% | 164 |
| 30 Months | -19.8% | 107 |
| Interim analysis. N at 18, 24 and 30 months are patients who have reached those time points and were seen for the scheduled visit. |
About the ReCharge Pivotal Trial
The ReCharge Clinical Trial is a randomized, double-blind, parallel-group, multicenter pivotal clinical trial in 234 patients at up to 12 sites testing the effectiveness and safety of VBLOC® vagal blocking therapy in EnteroMedics' second generation Maestro® Rechargeable (RC) System. All patients in the study will receive an implanted device and will be randomized in a 2:1 allocation to treatment or control groups. The control group will receive a functional, but non-active device without lead placement on the vagus nerve that will deliver no charge to the vagus nerve during the study period. All patients are expected to participate in a weight management counseling program.
About Maestro® RC System
The Maestro® Rechargeable (RC) System is powered by an internal, rechargeable battery. The battery is recharged via an external mobile charger and transmit coil that the patient uses for a short time each week. The Maestro® RC System delivers VBLOC® vagal blocking therapy via two small electrodes that are laparoscopically implanted and placed in contact with the trunks of the vagus nerve just above the junction between the esophagus and the stomach.
About VBLOC Therapy
EnteroMedics developed VBLOC® vagal blocking therapy to offer bariatric surgeons and their patients a less invasive alternative to existing surgical weight loss procedures that may present significant risks and alter digestive system anatomy, lifestyle and food choices. VBLOC® Therapy is delivered via the Maestro® System through laparoscopically implanted leads to intermittently block the vagus nerves using high-frequency, low-energy electrical impulses. VBLOC® Therapy is designed to target the multiple digestive functions under control of the vagus nerves and to affect the perception of hunger and fullness.
About EnteroMedics Inc.
EnteroMedics is a development stage medical device company focused on the design and development of devices that use neuroblocking technology to treat obesity and other gastrointestinal disorders. EnteroMedics' proprietary neuroblocking technology, VBLOC® vagal blocking therapy, is designed to intermittently block the vagus nerves using high-frequency, low- energy, electrical impulses. These electrical impulses are delivered by a neuroregulator, EnteroMedics' Maestro® RC System, which is powered by an integrated rechargeable battery. For more information, visit
