4. The subject has normal renal function as evidenced by creatinine clearance >90 mL/min based on the Cockcroft-Gault glomerular filtration rate estimation: (140 - Age) × (Weight in kg) × (0.85 if female) / (72 × serum creatinine).

5. The subject is considered by the investigator to be in good general health as determined by medical history, clinical laboratory test results, vital sign measurements, 12-lead ECG results, and physical examination findings at screening and check-in.

Female subjects of childbearing potential must use 2 effective methods of birth control (eg, diaphragm with spermicide, intrauterine device, condom with foam or vaginal spermicide) or abstinence [true abstinence when this is in line with the preferred and usual lifestyle of the subject]) during the study and for 90 days after the last dose of vorasidenib or be surgically sterile (eg, hysteroscopic sterilization, bilateral tubal ligation or bilateral salpingectomy, hysterectomy, or bilateral oophorectomy), or postmenopausal (defined as amenorrhea 12 consecutive months and documented plasma follicle-stimulating hormone level >40 IU/mL).

4. The subject has any surgical or medical condition(s) possibly affecting drug absorption, distribution, metabolism, and excretion (eg, cholecystectomy, bariatric procedure). Subjects with appendectomy may be included.

5. The subject is a woman of childbearing potential who is pregnant, lactating, or planning to become pregnant within 90 days after the last dose of study drug, or the subject is on oral contraceptive pills (moderate CYP1A2 inhibitors) within 14 days or 5 half-lives (whichever is longer) prior to the first dose administration and/or during the study.

6. The subject has a positive test result for hepatitis B surface antigen or antibodies to hepatitis C virus (HCV) (if antibody test result is positive, it will be followed up with an HCV RNA test to confirm; those with undetectable HCV RNA will not be excluded).
