Comment: Therefore, P-gp is expected to play a minor role in regulating tazemetostat absorption and the P-gp-mediated DDI risk at intestinal absorption is low for tazemetostat as a victim drug

Sample Use Guides

Malignant Mesothelioma, Synovial Sarcoma: patients receive 800 mg of oral tazemetostat two times daily. Diffuse Large B Cell Lymphoma: patients receive 200, 400, 600 or 800 mg of the drug twice a day in combination with rituximab (IV, 375 mg/m2, day 1),pPrednisolone (PO, 40 mg/m2 in the morning, day 1 to day 5), doxorubicine (IV, 50 mg/m2, day 1), cyclophosphamide (IV, 750 mg/m2, day 1), vincristine (IV, 1.4 mg/m2, day 1): 8 cycles, every 21 days.
Route of Administration: Oral
Treatment of WSU-DLCL2 with 1uM tazemetostat for 4 days resulted in a concentration-dependent reduction in global H3K27Me3 levels with an IC50 value of 9 nmol/L. Treatment of WSU-DLCL2 cells with 200 nM tazemetostat; KARPAS-422 with 100 nM; SU-DHL-6 with 200 nM; and Pfeiffer with 0.5 nM inhibited cell proliferation with IC50 values of 0.0086, 0.0018, 0.0047 and 0.00049 uM, respectively.
