Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is being done to assess the efficacy of a saliva- based biomarker to predict response to semaglutide for the treatment of obesity.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The purpose of this study is to test the effectiveness of semaglutide 2.4 mg SQ weekly in patients with obesity with a positive MyPhenome test for abnormal postprandial satiety compared to patients with obesity with a negative MyPhenome test for abnormal postprandial satiety.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

* History of bariatric surgery including lap band and bariatric endoscopy
* Significant untreated psychiatric dysfunction based upon screening with the Hospital Anxiety and Depression Inventory (HAD), Questionnaire on Eating and Weight Patterns (binge eating disorders and bulimia) and Columbia Suicide Severity Rating Scale (C-SSRS). If such a dysfunction is identified by an anxiety or depression score \>11 or difficulties with substance or eating disorders, the participant will be excluded and given a referral letter to his/her primary care doctor for further appraisal and follow-up. Any suicidal ideation of type 4 or 5, any suicide attempt during the patient's lifetime, or any suicidal behavior in the last month.
* Current use of anti-obesity medications or GLP1R agonists for Type 2 Diabetes
* Any contraindication to FDA-approved GLP1R agonists
* A person who is pregnant or wanting to become pregnant
* Once the positive or negative cohort is filled at 2:1 ratio, some patients will be screen failed if their gene cohort is full.
