Clinical Trial Summary

Primary Obesity Surgery Endoluminal 2.0, or POSE 2.0, (USGI Medical, San Clemente, CA) creates full-thickness plications of gastric tissue endoscopically to shorten the stomach and narrow its aperture for weight loss in patients with obesity. Adults with obesity and non-alcoholic NAFLD were allocated based on preference and motivation to undergo the POSE 2.0 procedure with lifestyle modification or lifestyle modification alone to study the impact of the POSE2.0 procedures on NAFLD parameters and metabolic profile. Co-primary endpoints included improvement in controlled attenuation parameter (CAP) and resolution of hepatic steatosis at 12 months. Secondary endpoints included total body weight loss (TBWL), change in serum measures of hepatic steatosis and insulin resistance, and device safety.

Eligibility

Inclusion Criteria:

1. Provision of signed and dated informed consent form.

2. Subject agrees to be compliant with study requirements and adhere to post-operative dietary & exercise recommendations for the duration of the study.

3. Subjects age >=18 years old.

4. Hepatic steatosis from NAFLD, as defined by a controlled attenuation parameter = 280 dB/m without alternate cause of liver disease measured by a Fibroscan XL.

5. Body Mass Index = 30kg/m2

6. If female, be either post-menopausal, surgically sterile, or agree to practice birth control during year of study and have negative serum HCG at screening/baseline.

7. Absence of current severe systemic disease (including, but not limited to: coronary artery disease, chronic obstructive pulmonary disease, congestive heart failure, cancer, and chronic renal disease).

8. Agrees not to undergo any additional weight loss interventional procedures or liposuction for 12 months following study enrollment.

9. Have not taken any prescription or over-the-counter weight loss medications OR those that can suppress appetite/induce weight loss for at least 6 months and agrees not to utilize for 12 months following study enrollment (including all stimulant medication).

10. Subjects must be willing to possibly forego any future weight loss procedures (i.e. Vertical Sleeve Gastrectomy) given the unknown long-term effects.

11. Residing within a reasonable distance from the Investigator's treating office (~50 miles) and willing and able to travel to the Investigator's office to complete all routine follow-up visits.

Exclusion Criteria:

1. History of (or intra-operative evidence of) prior bariatric, gastric or esophageal surgery.

2. Esophageal stricture or other anatomy and/or condition that could preclude passage of endoluminal instruments or procedure execution.

3. Moderate gastro-esophageal reflux disease (GERD), defined as symptoms that cause subject severe discomfort, compromise performance of daily activities, and/or condition is not entirely controlled with drug therapy.

4. Large hiatal hernia (>3 cm) by history or as determined by pre-enrollment endoscopy.

5. Pancreatic insufficiency/disease.

6. History of gastroparesis or symptoms that would be suggestive of gastroparesis or generalized dysmotility (e.g. esophago-gastric motility issues and lower esophageal sphincter abnormalities).

7. Pregnancy or plans of pregnancy in the next 12 months.

8. History of a known diagnosis or pre-existing symptom of rheumatoid arthritis, scleroderma, system lupus, or other autoimmune connective tissue disorder.

9. Immunosuppressive medications or systemic steroids (i.e., oral prednisone) within 6 months of Visit 1. Intranasal/inhaled steroids are acceptable.

10. Unable or unwilling to avoid use of aspirin and/or non-steroidal anti-inflammatory drugs (NSAIDs), or other medications known to be gastric irritants beginning two weeks prior to enrollment and throughout the entire study.

11. History of inflammatory disease of the GI tract; coagulation disorders; hepatic insufficiency or cirrhosis.

12. Active gastric erosion, lesion, or gastric/duodenal ulcer.

13. History of or current platelet or coagulation dysfunction, such as hemophilia.

25. Subjects with a personal history of allergic/anaphylactic reactions including hypersensitivity to the drugs or materials that will be utilized in the study procedure.

26. Physician's assessment that the subject is not an appropriate candidate.

Intervention

Procedure:
• POSE2.0 procedure
The POSE 2.0 involves full-thickness plications by suture anchor pairs that shorten and tabularize the stomach along its greater curvature. The POSE 2.0 procedure was carried out using the Incisionless Operating Platform (USGI Medical, San Clemente, CA)

Behavioral:
• Life style and behavioral intervention
The intervention focuses on caloric restriction diet, physical activity, and behavioral modification targeted toward weight loss and administered by a health care professional months for the 12 months duration of the study.
