Solid Tumor Clinical Trial
Official title:
A Phase I, Open-label Multi-dose Two-part Study to Characterize the Effects of a Strong CYP3A4 Inhibitor and a Strong CYP3A4 Inducer on the Steady-State Pharmacokinetics of Tazemetostat (EPZ-6438) in Subjects With Advanced Malignancies

Study type | Interventional |
The participants of this study will have advanced malignancies (also known as advanced cancer). The main aim of this trial will be to study the blood levels (known as pharmacokinetics) of the tazemtostat (the study drug) when administered in combination with another drug. Part 1 of the study will evaluate the interaction between the drugs tazemetostat and itraconazole. Part 2 of the study will evaluate the interaction between the drugs tazemetostat and rifampin For both Parts 1 and 2, safety and the level that effects of the study drug can be tolerated (known as tolerability) will be assessed throughout.

Uncontrolled concurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, clinically significant cardiac arrhythmias, or psychiatric illness/social situations that would limit compliance with study requirements. 6.

Regular alcohol consumption must not exceed 16 units for males and 7 units for females per week (2 units equals 40mL [a can] of beer, 175mL [a standard glass] of wine, or 50 mL [2 small shots] of spirits 12. Any form of marijuana use. 13. History of drug abuse (including alcohol) within the last 6 months prior to screening. |
