Clinical Trial Summary

The purpose of this study is to evaluate endoscopic sleeve gastroplasty (ESG) for the treatment of obesity. The ESG procedure is an U.S. Food and Drug Administration (FDA) approved procedure for the treatment of obesity - patients with a body mass index (BMI) 30-50 kg/m2. This procedure is FDA approved; however, Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP)-Accredited centers (such as Houston Methodist Hospital) must receive approval from an Institutional Review Board (IRB) in order to perform primary procedures, such as ESG, that are not endorsed by the American Society for Metabolic and Bariatric Surgery (ASMBS).


Description:

Obesity has become an epidemic on a national and international scale with immense burden of disease. Approximately one out of every three United States (U.S.) adults are characterized as having obesity with the global prevalence having nearly tripled over the last four decades to include over 650 million people. Although diet and exercise are essential, these interventions alone typically result in only 1-3% total weight loss. Pharmacotherapy is effective but has side effects and carries the risk of weight recurrence once discontinued. While bariatric surgery is the most robust treatment option, only 1% of eligible patients undergo surgery, leaving a tremendous need for effective and safe therapies. Helping to bridge this gap in available treatments, the endoscopic sleeve gastroplasty (ESG) procedure provides a way to improve access to validated, efficacious, and safe anti-obesity treatments. ESG is an endoscopic weight loss procedure. The procedure uses an endoscopic suturing device, which has received FDA authorization as a minimally invasive procedure to facilitate weight loss for adults with obesity (BMI 30-50 kg/m2) who have been unable to lose weight or maintain weight loss through more conservative measures such as diet and exercise. This procedure involves endoscopic suturing to reduce the volume of the stomach endoscopically by approximately 70% to 80% its original size. Following the procedure, the new stomach appears similar to the surgical sleeve stomach, although the procedure is considered less invasive with fewer complications compared to a surgical sleeve procedure. This study aims to perform ESG for patients with obesity, defined as a BMI 30-50 kg/m2. Additionally, data collection of relevant weight-related and metabolic outcomes, including comorbidity resolution will be collected retrospectively from the study to assess efficacy and safety of the ESG procedure. Data collection for the MBSAQIP registry will be recorded on a monthly basis.

Intervention

Procedure:
Endoscopic Sleeve Gastroplasty (ESG)
The ESG procedure uses the Apollo OverStitch endoscopic suturing device, which has received FDA authorization as a minimally invasive procedure to facilitate weight loss for adults with who have been unable to lose weight or maintain weight loss through more conservative measures such as diet and exercise. This procedure involves endoscopic suturing to reduce the volume of the stomach endoscopically by approximately 70% to 80% its original size. Using the Apollo OverStitch or APOLLO ESG and ESG SX Systems, the ESG procedure is performed be folding the stomach in on itself (endoscopically) and placing full-thickness sutures through the wall of the stomach to maintain this narrow, smaller size. Following the procedure, the new stomach appears similar to the surgical sleeve stomach, although the procedure is considered less invasive with fewer complications compared to a surgical sleeve gastrectomy.
Device:
Apollo OverStitch endoscopic suturing device
Apollo ESG is the first and only device to be authorized by the FDA to perform the ESG procedure to facilitate weight loss in patients with obesity (BMI 30 to 50 kg/m2). The FDA identifies this generic type of device as an Endoscopic suturing device for altering gastric anatomy for weight loss.

Outcome

Type Measure Description Time frame Safety issue
Primary Number of participants with technically successful completion of the ESG procedure Per the ASMBS, IRB approval must be for performing the ESG procedure, and not solely for data collection of outcomes from these procedures, with data collected by the MBSAQIP registry. Therefore, the primary outcome is performing the ESG procedure (defined as ability to successful complete the procedure). Procedural success will be defined by ability to successful reduce the size of the stomach using the Apollo OverStitch or APOLLO ESG and ESG SX systems. Technical success further identified by ability to insert the endoscopic suturing device, perform endoscopic reduction of the stomach, and success removal of the device. Procedural completion over 10 year period
Primary Number of participants with treatment-related adverse events as assessed by CTCAE v4.0 Treatment-related adverse events as assessed by CTCAE v4.0 will be reviewed on a monthly basis by the bariatric medical director, bariatric clinical review, and program manager. Per the U.S. FDA, identified risks to health including device- and/or procedure-related adverse events include: death, gastrointestinal bleeding, obstruction, perforation, injury to organs adjacent to the stomach, perigastric leak, and nausea, infection, pain, pneumoperitoneum, pneumothorax, and pulmonary embolism, weight gain, and adverse tissue reaction. All patients are recorded and entered into this MBSAQIP registry with outcomes tracked in real-time via the electronic medical record, and all ESG complications discussed at the Metabolic and Bariatric Surgery Committee Meetings which are held quarterly. This includes monitoring emergency department visits, readmissions, and patient transfers to any inpatient facility during the 30-day postoperative period. 30 days post-procedure
Secondary Change in body mass index (BMI) measured by kg/m2 Data collection of relevant weight-related outcomes, including body mass index (BMI, measured in kg/m2) will be performed on day of procedure and at relevant follow-up periods (day of procedure, 4 weeks, 3 months, 6 months, and 12 month intervals). From this, change in BMI with be measured to determine change at relevant follow-up intervals. BMI (kg/m2) measured day of procedure, 4 weeks, 3 months, 6 months, and 12 month intervals
Secondary Change in hemoglobin A1C (%) Data collection of relevant comorbidity-related outcomes, including A1C (measured in percentage) will be performed pre-procedure and at relevant follow-up periods (pre-procedure, 3 months, 6 months, and 12 month intervals). This will be measured for all patients, regardless of presence or absence of diabetes mellitus (DM). From this, change in A1C will be calculated to determine and change in blood glucose (A1C). A1C measured pre-procedure, 3 months, 6 months, and 12 month intervals
