Formoterol in Diabetes
Prospective Randomized Pilot Trial of Formoterol in Patients With Diabetic Kidney Disease
Medical University of South Carolina
120 participants
Dec 1, 2025
INTERVENTIONAL
Conditions
Summary
The purpose of the study is to evaluate if formoterol fumarate is effective in treating patients with diabetic kidney disease. Study participants will be randomly assigned to either receive formoterol fumarate (in addition to their current standard of care treatment) or standard of care treatment only. Study participants will have a 50% chance of receiving formoterol fumarate and a 50% chance of not receiving formoterol fumarate. Both groups will continue their standard of care treatment during the study. The primary goal is to gather data on feasibility and effect sizes to properly power a future clinical trial.

Interventions
Investigators chose to use the long-acting β2-AR agonist, formoterol, because of its efficacy and safety profile in patients with COPD and because formoterol showed the most association with protection from progression of CKD in our retrospective study.
