Summary
This study looked at how two common drugs (itraconazole and probenecid) change the way the body handles a new experimental medicine called PF-07220060. It involved 25 healthy adults who took the new medicine alone and then again with the other drugs. The goal was to understand potential interactions before testing the medicine in patients.
