Healthy, Hepatic Impairment

Brief summary

The main purpose of this study is to assess how selpercatinib gets into the blood stream and how long it takes the body to remove it when administered to participants with impaired hepatic function compared to healthy participants. Information about safety and tolerability will be collected. The study will last up to about 7 weeks, inclusive of screening period.
