NCT05264727 · Sponsor: Mayo Clinic

What this trial means for you

This study is active, not recruiting — it is not currently taking new participants, but its results may matter for treatments you're considering. It's studying Dextrose, Clinisol 15% for healthy, type 2 diabetes, obesity.

Who can joinAll sexes, 25 Years – 65 Years
Healthy volunteersAccepted
What you'd takeDextrose, Clinisol 15%
Study length~2.6 years overall

TypeInterventional (you receive treatment)

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

This study is being done to better understand how amino acids alter the release of glucagon and insulin compared to glucose alone in health and disease.
