About this trial

This is an interventional treatment trial for Obesity focused on measuring BMI of 30 or greater

Eligibility Criteria

18 Years - 65 Years (Adult, Older Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

  • Willing to provide consent.
  • Patients with obesity BMI> 30 kg/m^2 and hungry gut phenotype.
  • Gender: men or women. Women of childbearing potential will have a negative pregnancy test before initiation of medication and within 48 hours of receiving radioisotope for the gastric emptying study.
  • Otherwise healthy individuals or with controlled chronic medical conditions such as type 2 diabetes.

Exclusion Criteria:

  • Structural or metabolic diseases/conditions that affect the gastrointestinal system, or functional gastrointestinal disorders. For screening the bowel disease questionnaire will be used to exclude subjects with irritable bowel syndrome.
  • Subjects with stool type Bristol classification 6-7 per bowel disease questionnaire.
  • Female subjects who are pregnant or breast-feeding.
  • Use of anti-obesity medications upon screening (ie., orlistat, phentermine-topiramate, liraglutide, semaglutide, bupropion-naltrexone), metformin or GLP-1 analogs.
  • Individuals who are currently on treatment for unstable cardiac, pulmonary, gastrointestinal, hepatic, renal, hematological, neurological, endocrine, and psychiatric disease.
  • Any acute or chronic condition or other disease that, in the opinion of the Investigator, would limit the subject's ability to complete and/or participate in this clinical study.
  • Significant untreated psychiatric dysfunction based upon screening. Hospital Anxiety and - Depression Inventory (HAD) score > 11 on depression scale, a self-administered alcoholism screening test (AUDIT-C) score >4 in men or >3 in women, and difficulties with substance or eating disorders determined by the Questionnaire on Eating and Weight - Patterns (binge eating disorders and bulimia); will mean the participant will be excluded and given a referral letter to his/her primary care doctor for further appraisal and follow-up. The provider will review the patient's alcohol intake over the past few months to confirm accuracy and determine study eligibility.
