EnteroMedics Inc. (NASDAQ: ETRM), the developer of medical devices using neuroblocking technology to treat obesity, metabolic diseases and other gastrointestinal disorders, today announced that the Company completed a pre-PMA (Premarket Approval) application meeting with the U.S. Food and Drug Administration (FDA) on May 15, 2013 regarding the Maestro® Rechargeable System's VBLOC® vagal blocking therapy as a treatment for obesity. In the meeting, the FDA indicated that, subject to acceptance of the application and validation and detailed review of the submitted data by the FDA, the Company can anticipate presenting the PMA before a future FDA Advisory Committee panel. The Company expects to submit a PMA for the Maestro Rechargeable System, based on the ReCharge Pivotal Trial, in the second quarter of 2013.

"We had a very open and productive meeting with the FDA and look forward to submitting our PMA, as anticipated, this quarter," said Mark B. Knudson, Ph.D., EnteroMedics' President and Chief Executive Officer. "We are confident that the Maestro System holds the unique potential to fill a significant gap that currently exists in the treatment options for people with obesity."

About Maestro Rechargeable (RC) System
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. The Maestro 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 has received CE Mark and has been listed on the Australian Register of Therapeutic Goods.

About the ReCharge Pivotal Trial
The ReCharge Pivotal Trial is a randomized, double-blind, sham-controlled, multicenter pivotal clinical trial in 239 randomized patients (233 implanted) at 10 sites testing the effectiveness and safety of VBLOC® vagal blocking therapy utilizing EnteroMedics' second generation Maestro® Rechargeable (RC) System. All patients in the trial received an implanted device and were randomized in a 2:1 allocation to treatment or control groups. The control group received a non-functional device during the trial period. In February, EnteroMedics announced that its ReCharge Trial demonstrated a statistically significant and clinically meaningful excess weight loss (EWL) outcome and excellent safety profile. This included an average EWL of approximately 25% for VBLOC Therapy-treated patients, with over 50% of those patients achieving at least a 20% EWL. While the results demonstrated an excellent safety profile that met the pre-specified trial measures, with both a positive benefit-to-risk equation and a medically meaningful and clinically significant effect over the control group, the results did not meet the study's predefined efficacy measures.

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 medical device company focused on the development and commercialization of its neuroscience based technology to treat obesity and metabolic diseases. EnteroMedics' proprietary technology, VBLOC® vagal blocking therapy, delivered by a pacemaker-like device called the Maestro® Rechargeable System, is designed to intermittently block the vagus nerves using high-frequency, low-energy, electrical impulses. VBLOC allows people with obesity to take a positive path towards weight loss, addressing the lifelong challenge of obesity and its comorbidities without sacrificing wellbeing or comfort. EnteroMedics' Maestro Rechargeable System has received CE Mark and is listed on the Australian Register of Therapeutic Goods.
