NCT ID NCT05630274

First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time

Summary

This completed Phase 1 study looked at whether a single dose of selpercatinib, a cancer drug, changes the heart's electrical activity (QT interval) in 32 healthy adults. Participants received selpercatinib, a placebo, or a control drug (moxifloxacin) in a crossover design. The main goal was to measure any heart rhythm effects to ensure the drug's safety for future use.
