Pharmacokinetics of Enasidenib (CC-90007) in Participants With Mild, Moderate and Severe Hepatic Impairment

A Phase 1 Open-Label Single-Dose Study to Assess the Pharmacokinetics of Enasidenib (CC 90007) in Subjects With Mild, Moderate and Severe Hepatic Impairment

This is a multi-center, open-label study to assess the PK of single 100 mg oral doses of enasidenib (CC-90007) in subjects with mild, moderate, and severe hepatic impairment (HI), and in matched healthy control subjects with normal hepatic function.

Degrees of hepatic impairment will be determined during screening by the subject's score according to Pugh's Modification of Child's Classification of Severity of Liver Disease.

Subjects will be enrolled in 4 Groups as follows:

• Group A: Approximately 8 subjects with mild hepatic impairment (with a Child-Pugh score of < 7) will be enrolled in Group A.
• Group B: Approximately 8 subjects with moderate hepatic impairment (with a Child-Pugh score of ≥ 7 to ≤ 9) will be enrolled in Group B.
• Group C: Approximately 8 subjects with severe hepatic impairment (with a Child-Pugh score of ≥ 10 to ≤ 15) will be enrolled in Group C.
• Group D: Approximately 8-24 healthy subjects with normal hepatic function will be enrolled in Group D. Subjects in Group D will be matched to subjects in Groups A-C with respect to sex, age (± 10 years), and weight (± 30 pounds). More than 1 subject with differing degrees of HI can be matched to a single control; however, all subjects with HI must be matched to at least 1 healthy match subject.

2. Subject is able to communicate with the Investigator, understand and comply with the requirements of the study, and agree to adhere to restrictions and examination schedules and other protocol requirements.
3. Subject is willing and able to adhere to the study visit schedule and other protocol requirements, including the restrictions.
4. 4. Male, or non-pregnant and non-nursing female between ≥ 40 and ≤ 75 years of age the time of signing the ICF..

8. Female subjects NOT of childbearing potential must:

   a. Have been surgically sterilized at least 6 months before screening, or be naturally postmenopausal.

9. Females of childbearing potential (FCBP) must have a negative pregnancy test at Screening and Baseline Visits. While receiving IP and for at least 2 months after taking the last dose of IP, FCBP who engage in activity in which conception is possible must use one of the approved contraceptive options.

10. Male subjects must:

    1. Practice true abstinence or
    2. agree to use a barrier method of birth control during sexual contact with a pregnant female or FCBP while participating in the study, during dose interruptions, and for at least 2 months after the last dose of IP, even if he has undergone a successful vasectomy.

    Inclusion Criteria for Subjects with mild, moderate, or severe hepatic impairment (Groups A-C)

    Each subject with mild, moderate, or severe hepatic impairment must also meet all the applicable criteria listed below for study entry:

11. Subject has moderate or severe hepatic impairment or cirrhosis due to chronic hepatic disease and/or prior alcohol use.

12. Subject has mild (Group A), moderate (Group B), or severe (Group C) hepatic impairment as defined by Child-Pugh Score.

    1. Group A subjects must have mild hepatic impairment and are required to have documentary confirmation of the diagnosis of cirrhosis made by biopsy, laparoscopy, or imaging study with a Child-Pugh score of < 7, at screening.

    • Subject (male or female) has a QTcF value ≤ 500 msec at screening.

15. Must be stable on a concomitant medication regimen before dosing with study drug).
16. Subjects may be treated with diuretics for ascites; however, subjects with severe ascites at time of enrollment may only be included at the discretion of the investigator with agreement of the Sponsor.

21. Subject must be in good health as determined by past medical history, PE, vital signs, ECG, and clinical laboratory safety tests. Clinical laboratory safety tests (ie, hematology, chemistry, and urinalysis) and 12-lead ECGs must be within normal limits or clinically acceptable as judged by the Investigator.
22. Subject has a normal or clinically acceptable 12-lead ECG at screening. In addition:
