Drug interaction study tests cancer Drug's effect on diabetes medication
NCT ID NCT05469113
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed Phase 1 study in 16 healthy adults looked at whether taking multiple doses of selpercatinib (a cancer drug) changes how the body processes repaglinide (a diabetes medication). Participants received both drugs in a fixed order, and researchers measured drug levels in the blood over 12 days. The goal was to gather safety and drug interaction information, not to treat any disease.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Selpercatinib (also known as LOXO-292) and repaglinide
- What this could lead to
- If successful, this study could help doctors understand how to safely combine selpercatinib with other drugs that are broken down similarly in the body.
- What could go wrong
- This is a small, early-stage study in healthy volunteers, not patients. It only looks at drug levels, not actual treatment effects, so results may not apply to real-world use.
