Brief summary

The purpose of this study is to assess how the body handles Abemaciclib when it is given with another drug called clarithromycin. The study doctor will measure the amount of Abemaciclib that is absorbed into the blood stream and the time that it takes to remove Abemaciclib from the body. The safety and tolerability of these drugs will be studied. Each participant will complete 2 study periods in fixed order. After screening, Period 1 will last approximately 8 days and Period 2 will last approximately 15 days. Participants who complete Period 2 may continue to receive Abemaciclib in 28-day cycles until discontinuation criteria are met.

50 mg single oral dose of Abemaciclib was administered on Period 1 Day 1 and on Period 2 Day 5. Clarithromycin 500 mg orally twice daily for 12 days. Clarithromycin dosing continued for 7 days following the single dose of Abemaciclib. After completing Period 2, eligible participants continued to receive 200 mg Abemaciclib Q12H on a 28-day cycle in a safety-extension phase until discontinuation criteria were met.
