What was measured

PK: (AUC0-tlast) was reported.

Analysis population: All participants in Part A who received at least one dose of abemaciclib and had evaluable PK data. Per planned analysis, PK analysis was performed as per the dose of study drug received.

Groups in this outcome

Part A: 70 mg/m² Abemaciclib

All part A participants who received 70 mg/m² abemaciclib were included under this arm.

Part A: 55 mg/m² Abemaciclib

All part A participants who received 55 mg/m² abemaciclib were included under this arm.
