Brief summary

The main purpose of this study is to conduct blood tests to measure how much LOXO-783 is in the bloodstream and how the body handles and eliminates LOXO-783 when administered alone or in combination with cholestyramine in healthy participants. The study will also evaluate the safety and tolerability of LOXO-783 with and without cholestyramine. Participation could last up to 63 days including screening period.
