What was measured

Blood samples were collected at specified timepoints. AUC0-12h was assessed using non-compartmental data analysis method. AUC0-12h was estimated by a combination of linear trapezoidal method on concentrations going up and logarithmic trapezoidal method on concentrations going down (Linear up/Log down method).

Analysis population: The PK population included all participants who had sufficient PK concentration data to calculate steady-state PK parameters in Part 2 and did not have any major protocol deviation that was deemed to greatly alter the steady-state exposure to tazemetostat or rifampin.

Groups in this outcome

Part 2: Tazemetostat

Participants received a single oral dose of 800 mg tazemetostat on Cycle 1 Day 1, BID dose of 800 mg of tazemetostat from Days 3 to 14 and a single oral dose of 800 mg tazemetostat on Day 15. From Days 17 to 23, they received an 800 mg BID dose of tazemetostat. On Day 24, subjects received a single dose of 800 mg tazemetostat. Participants continued to receive tazemetostat treatment at the recommended therapeutic dose (oral 800 mg tazemetostat BID), from Day 27 (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).
