Official title
The Roles of Endocannabinoids in Insulin Secretion and Action
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Background: \- The endocannabinoid system is involved in different body functions and processes. It helps regulate appetite and mood, and sends signals to the nervous system. It may also be involved in how the body produces insulin during digestion. Researchers want to test two drugs that work on the endocannabinoid system: nabilone and CP-945,598. These drugs may be able to affect insulin levels in the blood. This information may suggest possible new treatments for people with diabetes. Objectives: \- To study how the endocannabinoid system is involved in insulin production and action. Eligibility: \- Healthy men between 21 and 55 years of age. Design: * Participants will be screened with a physical exam and medical history. They will provide blood and urine samples. They will also have imaging studies to test their brain responses, especially to food-related cues. Some participants will also have a study visit to test their insulin resistance levels. * Participants will have four separate study visits 6 weeks apart. They will keep a food diary before each visit. At each visit, they will have one of the following combinations of drugs: * Double placebo * Placebo and nabilone * Placebo and low dose of CP-945,598 * Placebo and high dose of CP-945,598. * Participants will have follow-up visits 1 week after each study visit. Blood samples will be taken....
