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.
We will connect you to the doctor responsible for this trial and help you get more information.

In situations where laboratory results are outside the permitted range, the investigator may retest the subject and the subsequent within range screening result may be used to determine the subject's eligibility.

Subjects with a history of Hepatitis B or C are eligible on the condition that subjects have adequate liver function as defined by the protocol and are hepatitis B surface antigen negative and/or have undetectable HCV RNA.
Male subjects must refrain from donating sperm starting at the planned first dose of investigational product (IP) until 30 days following the last dose of IP
Male subjects with a female partner of childbearing potential must:
Be vasectomized, or
Remain abstinent or use a condom as defined in Section 188.8.131.52.2, starting at the planned first dose of IP until 30 days following the last dose of IP. The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the subject. Periodic abstinence (e.g., calendar, ovulation, sympto-thermal, or post-ovulation methods) and withdrawal are not acceptable methods of contraception.
Female partners of male subjects who are of childbearing potential must also adhere to one of the following:
Placement of an intrauterine device or intrauterine system.
Established use of oral, injected, or implanted hormonal methods of contraception or use of a barrier method of contraception.
Progesterone only oral contraception, where inhibition of ovulation is not the primary mode of action.
Women of childbearing potential or female partners of male subjects must abide by the contraception measures defined by the protocol

Cytogenetic testing and DNA sequencing will be conducted following an abnormal result of bone marrow aspirate/biopsy.

Is immunocompromised, including subjects with known human immunodeficiency virus (HIV) infection
Has known hypersensitivity to any of the components of IP.
Is unable to take oral medications, has a history of surgery that would interfere with the administration or absorption of oral medication, has malabsorption syndrome or any other uncontrolled gastrointestinal condition (e.g., nausea, diarrhea or vomiting) that might impair the bioavailability of IP
Has an uncontrolled intercurrent illness including, but not limited to, uncontrolled infection, or psychiatric illness/social situations that would limit compliance with study requirements.
Is unwilling to adhere to contraception criteria from time of enrollment in study to at least 30 days after last dose of IP.
