What was measured

Blood samples were collected at specified timepoints. Tmax was assessed using non-compartmental data analysis method.

Analysis population: The PK population included all participants who had sufficient PK concentration data to calculate steady-state PK parameters in Part 1 and did not have any major protocol deviation that was deemed to greatly alter the steady-state exposure to tazemetostat or itraconazole.

Groups in this outcome

Part 1: Tazemetostat

Participants received a single oral dose of 400 mg tazemetostat on Cycle 1 Day 1, BID dose of tazemetostat 400 mg on Days 3 to 14 and single dose of tazemetostat 400 mg on Day 15. From Days 21 to 35, they received a 400 mg BID dose of tazemetostat. On Cycle 1 Day 36, they received a single dose of 400 mg tazemetostat. Participants continued to receive tazemetostat treatment at the recommended therapeutic dose (oral 800 mg tazemetostat BID), from Day 40 (Cycle 2 Day 1) for each subsequent cycle of 28-day duration until Investigator assessed clinical progression per standard practice, unacceptable treatment related toxicity/withdrawal; survival follow-up (until death/study closure).
