What this study is about
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.
View original scientific description
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).
Interventions
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.
Primary outcome measures
Number of participants with technically successful completion of the ESG procedure
Time frame: Procedural completion over 10 year period
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.
Number of participants with treatment-related adverse events as assessed by CTCAE v4.0
Time frame: 30 days post-procedure
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.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Patients with BMI 30 to 50 kg/m2
- Patients that have been unable able to lose weight, or maintain weight loss, through more conservative measures (i.e., lifestyle interventions including diet and exercise) per the FDA approval for the Apollo ESG device. Lifestyle interventions may include traditional diet and anaerobic or aerobic exercise, including resistance training.
Exclusion criteria
- Patients who are actively pregnant
- Active tobacco use (defined as tobacco within 4 weeks prior to the procedure)
- Active gastric mucosal lesions
- Active bleeding or potential bleeding gastric lesions (i.e., ulcers, erosive gastritis, varices, or vascular malformations)
- Neoplastic lesions (i.e., esophageal, gastric, or small bowel cancer)
- Hiatal hernia \>5 cm
- Severe coagulopathy and antiplatelet/anticoagulant therapy that cannot be corrected
- Psychiatric disorders not assessed or cleared by a psychologist or psychiatrist actively participating in that patient's care (i.e., affective disorders not under medical supervision or refractory to medical therapy and all eating disorders such as anorexia nervosa, binge eating disorder, specified feeding and eating disorders, avoidant restrictive food intake, and rumination)
- Patients with endoscopic interventions that are contraindicated

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
