Part A: Subjects enrolled in Part A will receive treatment with oral tazemetostat tablets 400 mg BID for 24 days beginning on Day 1. Subjects will receive fluconazole 400 mg once daily for 4 days starting on Day 16. Tazemetostat 400 mg BID will continue through Day 24. Subjects will then receive tazemetostat 800 mg BID starting on Day 25.

Part B: Subjects enrolled in Part B will receive single oral doses of repaglinide 0.25 mg and omeprazole 20 mg on Day 1. Administration of tazemetostat 800 mg BID will begin on Day 2. On Day 16, subjects again will receive single oral doses of repaglinide 0.25 mg and omeprazole 20 mg approximately 1 hour after the morning dose of tazemetostat. Subjects also will receive omeprazole 20 mg once daily in the morning on Days 16 through 19.

Tazemetostat is a selective oral small molecule inhibitor of EZH2

Tazemetostat

200mg will be orally administered QD for 4 days in order to determine CYP3A4 inhibition when administered concomitantly with tazemetostat

Using omeprazole as a probe substrate, 20mg will be orally administered for a total of 5 days in order to determine the potential of tazemetostat to inhibit or induce CYP2C19. Omeprazole is also being used to determine the effect of increased gastric pH on metabolism of tazemetostat.

Using repaglinide as a probe substrate, 25mg will be orally administered for a total of 2 days in order to determine the potential of tazemetostat to inhibit or induce CYP2C8.

This is a Phase 1, open-label, two-part, safety, PK, and activity study designed to characterize the DDI potential of tazemetostat. Tazemetostat will be taken orally BID continuously in 28-day cycles in both study parts.

Open-Label, Multicenter, Two-Part, Phase 1 Study to Characterize Effects of a Moderate CYP3A Inhibitor on PK of Tazemetostat, Effects of Tazemetostat on PK of CYP2C8 and CYP2C19 Substrates, and Effect of Increased Gastric pH on PK of Tazemetostat in B-cell Lymphoma or Advanced Solid Tumor Patients

Subjects enrolled in Part B received single oral doses of repaglinide 0.25 mg and omeprazole 20 mg on Day 1. Administration of tazemetostat 800 mg twice daily began on Day 2. On Day 16, subjects again received single oral doses of repaglinide 0.25 mg and omeprazole 20 mg approximately 1 hour after the morning dose of tazemetostat. Subjects also received omeprazole 20 mg once daily in the morning on Days 16 through 19. Blood samples for analysis of plasma repaglinide, repaglinide metabolites, omeprazole, 5-OH-omeprazole, and omeprazole sulfone were collected predose and over 7 hours after administration on Day 1 and Day 16.
