研究概览
简要总结
The main purpose of this study is to measure how much of pirtobrutinib (LOXO-305) gets into the bloodstream and how long it takes the body to eliminate it in participants with impaired liver function and healthy participants. The side effects and tolerability of pirtobrutinib will also be evaluated. Participation could last about 46 days.
