Details and patient eligibility
About
The purpose of this study is to determine how an investigational treatment (maribavir) is handled by the body when administered with two already approved drugs (digoxin and dextromethorphan). The study will also look at the safety and tolerability when maribavir is coadministered with digoxin and dextromethorphan versus digoxin and dextromethorphan alone.
