Hyperinsulinemia study: Diazoxide Oral Suspension vs Deuterated water
Official title Effect of Insulin Lowering on Lipogenesis
ClinicalTrials.gov ID: NCT07403604
What this study is testing
What is Diazoxide Oral Suspension?
This is an investigational liquid medicine being studied to see if it helps people with obesity, insulin resistance, and fatty liver disease. It is designed to lower the amount of insulin produced by the body, which may reduce the liver's production of new fat.
Also referred to as Proglycem.
Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- This study wants to see if lowering high insulin levels with a drug called diazoxide reduces the liver's production of new fat.
- Who it's for
- The study is looking for adults with obesity, high insulin levels, and fatty liver disease.
- What's involved
- Participants will take pills for one week, then wait a few months before taking pills for another week. They will also drink special water, have blood drawn, and give saliva samples.
- Time commitment
- The study involves two one-week treatment periods separated by a 4 to 12 week break, with several visits for tests.
- Phase 1: an early, usually small safety study
- You might receive a placebo (an inactive treatment) instead of the study drug, decided by chance. You may not know which one you got.
