Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The investigators will recruit obese subjects with pre-diabetes or type 2 diabetes for the proposed clinical study for 5 visits. After informed written consent is obtained, subjects will be admitted to the Clinical Research Center, and will undergo upper endoscopic injection of Botox into the duodenal wall. The investigators anticipate that injections of Botox into the duodenal wall will result in significant weight loss and improvements in glucose tolerance and duodenal nutrient sensitivity. Subjects will be studied over a period of 6 months. Subjects will be asked to complete 5 study visits: On the first visit, each subject will undergo an oral glucose tolerance test. At visit 2, subjects will undergo an esophagogastroduodenoscopy procedure for the delivery of Botox to the duodenal wall. Visits 3-5 will be made 1, 3, and 6 months later. On every study visit, body weight and body composition will be recorded and oral glucose tolerance test will be performed. Nutrient sensing test will be performed at visits 1 and 3.
