What this trial means for you
This study is recruiting now at 1 US site. It's studying Exendin-9 is a 30 amino acid peptide that is an established competitive antagonist of the GLP-1 receptor. Subjects will receive exendin-9 by intravenous infusion at a rate of 600 pmol/kg/min, Dexamethasone for diabetes (dm).
What participants typically get: study medication (or placebo, if the trial uses one) and study-related medical care at no cost, plus close monitoring. Compensation for time and travel varies by study — ask the site. Note that in many trials you can't choose your treatment group, and some participants receive a placebo.
The study, in the sponsor's words
Glucagon secretion from α-cells has long been viewed as primarily a counterregulatory mechanism - e.g. an agent with a role to prevent blood sugar from decreasing to levels that compromise function. Our group, along with other researchers, have begun to identify a much more complex role for α-cells, raising questions about when and how glucagon may influence blood glucose levels. This proposal looks to detail proglucagon peptide secretion from α-cells and the impact this has on β-cell function and glucose tolerance, in preclinical studies of human islets and translational studies in human subjects. This protocol registration describes Aim 2 from this NIH grant which involves 2 study populations and separate protocols but addresses a common question. Aim 3 in the grant is focused on a separate hypothesis and will be conducted and published separately from Aim 2.
