First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This completed Phase 1 trial studied how two drugs, roflumilast (used for COPD) and sitagliptin (used for diabetes), affect blood sugar and gut hormones in 29 healthy volunteers aged 21-55. Participants received each drug alone, together, or a placebo, then drank a nutritional shake to measure hormone responses. The goal was to understand how these drugs might lower blood sugar, which could lead to new treatments for type 2 diabetes.
