NCT06914765 | NOT YET RECRUITING | Obese Adolescents

ESG in Obese Adolescents
Sponsor:

Children's Hospital of Philadelphia

Information provided by (Responsible Party):

Michael Manfredi

Brief Summary:

The primary goal of this pilot study is to learn if the use of the Apollo Endosurgery ESG System is a safe, well tolerated intervention for weight loss in adolescents with obesity. Secondary outcomes will evaluate the effectiveness of Endoscopic Sleeve Gastroplasty (ESG) in long-term reduction of weight, improvements in obesity-related co-morbidities and improvements in quality of life. Participants will: * Have their stomach volume reduced with the ESG procedure (study intervention), rather than with a bariatric surgery, under general anesthesia * Have a few additional fasting blood tests drawn on top of standard bloodwork before and after the ESG procedure * Undergo pregnancy testing (female participants only) * Be admitted overnight to the hospital for recovery and monitoring following the ESG procedure * Have a physical examination performed at study follow-up visits * Participate in surveys about any side effects from the procedure and about quality of life * Follow-up with the study team. * Participants will still be seen in the multidisciplinary Bariatrics Clinic team consisting of an obesity medicine doctor, registered dietician, physical activity specialist, and psychologist as part of normal standard of care.

BMI ≥95th percentile to 120% of the 95th percentile on the Centers for Disease Control and Prevention (CDC) growth curve with at least one obesity related comorbidity; OR BMI ≥ 120% to 140% of the 95th percentile on the CDC growth curve regardless of the presence or absence of comorbidities. Clinically significant obesity related comorbidities including type 2 diabetes mellitus, idiopathic intracranial hypertension (IIH), non-alcoholic steatohepatitis (NASH) now called metabolic dysfunction-associated steatohepatitis (MASH), Blount's disease, Slipped Capital Femoral Epiphysis (SCFE), sleep apnea defined as AHI ≥ 5, Gastroesophageal Reflux Disease (GERD), hypertension, or dyslipidemia.
  • 3. Must have a documented history of weight management and weight loss attempts with supervised diets and exercise programs for at least 6 months from a Healthy Weight provider.
  • 4. All female subjects must have a negative serum pregnancy test.
  • 5. Has a signed note from a medically supervised weight loss program that the patient demonstrates commitment to nutrition, psychological, and physical activity evaluations and follow-ups in the Healthy Weight clinics, without frequent non-compliance or no-shows.
  • 6. Demonstrates ability to understand what dietary and physical activity changes will be required for optimal postoperative outcomes based on psychology assessment.
  • 7. Evidence for mature decision making, with appropriate understanding of potential risks and benefits of the procedure as deemed by a clinical psychologist.
  • 8. No documented genetic cause for obesity or excessive weight gain such as Prader-Willi syndrome
  • 9. Evidence that family and patient have the ability and motivation to comply with recommended treatments pre- and postoperatively. Evidence may include a history of reliable attendance at office visits for weight management and compliance with other medical needs.
  • 10. Female participants must agree to avoid pregnancy for the duration of the study and acknowledge that they will be withdrawn from the study if they do become pregnant.
  • 11. Patients agree to refrain from any type of additional weight loss surgery, reconstructive surgery, or weight-altering medications that would affect body weight.

  • 2. Females who are pregnant or lactating.

  • 12. Recently (within previous 3 months) prescribed or initiated therapy with medication(s) known to cause significant weight gain or weight loss including but not limited to a glucagon-like peptide-1 (GLP-1) Receptor Agonist, or is likely to require treatment with such medication(s) during the study.
  • 13.
