Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this research study is to help us to better understand how leptin regulates blood sugar levels. Leptin is a recently discovered hormone, which is made in fat cells. Leptin is secreted by fat and acts as a signal to the brain to decrease appetite and influences how the body regulates blood sugar levels. A synthetic form of leptin (A-100), an investigational drug and has not yet been approved by the Food and Drug Administration (FDA), will be administered to participants in this study. The expected duration of your participation is 3 study visits, which will be spread over 3-4 weeks. This study involves having fat and muscle biopsies after receiving leptin under local anesthesia in the General Clinical Research Center (GCRC), surgical unit, and/or Endocrinology exam room at the Beth Israel Deaconess Medical Center.
