6. Subject has the following disease status:

1. Refractory to, or relapsed after first, second, or third line regimen of intensive therapy for AML (eg, the "7 + 3" protocol) with at least 5% leukemic blasts in bone marrow (the minimum number of treatment cycles of the intensive therapy is per the investigator's discretion); or
2. Refractory to, or relapsed after first, second or third line low-intensity AML therapy (eg, low dose cytarabine (LDAC), azacitidine or decitabine) with at least 5% leukemic blasts in bone marrow after at least 2 treatment cycles; or
7. Subject has Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1 or 2.
8. Subject has IDH2 gene mutations revealed by local testing in samples of bone marrow aspirate and/or peripheral blood, and confirmed positive in bone marrow aspirate and/or peripheral blood. Local testing may be performed during screening or within two months prior to screening with appropriate documentation and concurrence of Sponsor's Medical Monitor.
9. Subject has adequate organ function defined as:

* Aspartate aminotransferase (AST)/serum glutamic oxaloacetic transaminase (SGOT) and alanine aminotransferase (ALT)/serum glutamic pyruvic transaminase (SGPT) = 3 x upper limit of normal (ULN), unless considered to be due to leukemic organ involvement, following review by the Sponsor's Medical monitor; and
* Serum total bilirubin = 1.5 x ULN, unless considered due to Gilbert's syndrome (eg, a gene mutation in UGT1A1) or leukemic organ involvement, following review by the Investigator and the Sponsor's Medical Monitor; and
* Estimated glomerular filtration rate (GFR) > 30 mL/min based on the Modification of Diet in Renal Disease (MDRD) formula: GFR (mL/min/1.73 m2) = 175 × (serum creatinine)-1.154 × (Age)-0.203 × (0.742 if female) × (1.212 if African American)
10. Females of childbearing potential (FCBP)2 may participate, providing they meet the following conditions:

* Agree to practice true abstinence from sexual intercourse or to use highly effective contraceptive methods (eg, combined [containing estrogen and progestogen] or progestogen-only associated with inhibition of ovulation, oral, injectable, intravaginal, patch, or implantable hormonal contraceptive; bilateral tubal occlusion; intra-uterine device; intrauterine hormone-releasing system; or male partner sterilization [note that vasectomized partner is a highly effective birth control method provided that partner is the sole sexual partner of the FCBP trial participant and that the vasectomized partner has received medical assessment of the surgical success]) at screening and throughout the study, and for 4 months following the last study treatment; and
* Have a negative serum ß-subunit of human chorionic gonadotropin (ß-hCG) pregnancy test (sensitivity of at least 25 mIU/mL) at screening; and
* Have a negative serum ß-hCG pregnancy test (sensitivity of at least 25 mIU/mL) within 72 hours prior to the start of study treatment in the Treatment Phase (note that the screening serum pregnancy test can be used as the test prior to the start of study treatment in the Treatment Phase if it is performed within the 72-hour timeframe).
11. Male subjects must agree to practice true abstinence from sexual intercourse or to the use of highly effective contraceptive methods with non-pregnant female partners of childbearing potential at screening and throughout the course of the study, and should avoid conception with their partners during the course of the study and for 4 months following the last study treatment.

Key exclusion criteria
Presence of any of the following will exclude a subject from enrollment:

1. Subject is suspected or proven to have acute promyelocytic leukemia based on morphology, immunophenotype, molecular assay, or karyotype.
2. Subject has AML secondary to chronic myeloid leukemia (CML).
3. Subject has received a targeted agent against an IDH2 mutation.

a. Prior treatment with an IDH2-targeted agent is acceptable if such treatment was interrupted for bone marrow or stem cell transplantation AND the patient was responsive to IDH2 treatment without progressive disease prior to transplantation.
4. Subject has received systemic anticancer therapy or radiotherapy < 14 days prior to the start of study treatment. Note that hydroxyurea is allowed prior to the start of study treatment for the control of leukocytosis (however, hydroxyurea should not be given within 72 hours prior to and after administration of azacitidine).
5. Subject has received non-cytotoxic or investigational agents < 14 days or 5 half-lives, whichever is longer, prior to the start of study treatment.
6. Subject has undergone hematopoietic stem cell transplantation (HSCT) within 60 days prior to the start of study treatment, or on immunosuppressive therapy post HSCT at the time of screening, or with clinically significant graft-versus-host disease (GVHD).

a. The use of a stable dose of oral steroid post-HSCT and/or topical steroids for ongoing skin GVHD is permitted.
7. Subject has persistent, clinically significant non-hematologic toxicities from prior therapies.
8. Subject has or is suspected of having central nervous system (CNS) leukemia.

a. Evaluation of cerebrospinal fluid is only required if CNS involvement by leukemia is suspected during screening.
9. Subject has active uncontrolled systemic fungal, bacterial, or viral infection (defined as ongoing signs/symptoms related to the infection without improvement despite appropriate antibiotics, antiviral therapy, and/or other treatment).
10. Subject has immediately life-threatening, severe complications of leukemia such as uncontrolled bleeding, pneumonia with hypoxia or shock, and/or disseminated intravascular coagulation.

Subject has significant active cardiac disease within 6 months prior to the start of study treatment, including New York Heart Association (NYHA) class III or IV congestive heart failure; acute coronary syndrome (ACS); and/or stroke; or left ventricular ejection fraction (LVEF) < 40% by echocardiogram (ECHO) or multi-gated acquisition (MUGA) scan obtained within 6 months starting study treatment.

1. The LVEF should be representative of the subject's daily status (ie, not collected during temporary disturbances such as sepsis, acute cardiac drug toxicity, acute pulmonary embolism, etc).
2. An imaging-based assessment of left ventricular function may be collected at Investigator's discretion as part of screening if needed to resolve uncertainty regarding prior tests or current clinical status.
12. Subject is known seropositive or is infected with human immunodeficiency virus (HIV) or has active infection with hepatitis B virus (HBV) or hepatitis C virus (HCV).
13. Subject is known to have dysphagia, short-gut syndrome, gastroparesis, or other conditions that limit the ingestion or gastrointestinal absorption of drugs administered orally.

15. Subject is a pregnant or lactating female.
16. Subject is known or suspected to have hypersensitivity to any of the components of PK probe compounds or study treatment.

Note: A subject may be enrolled into an alternate arm of the study to which the subject does not have hypersensitivity if that alternate arm has not been filled, and if the alternate arm is available in the respective country. Subject is planning, or has reasonable probability, to violate the restrictions. Note in particular the medication restrictions.
17. Subject has QTc interval (ie, Fridericia's correction [QTcF]) = 480 ms or other factors that increase the risk of QT prolongation or arrhythmic events (eg, heart failure, hypokalemia, family history of long QT interval syndrome) at screening.

18. In conjunction with the restrictions, subject is taking the following CYP-sensitive substrate medications that have a narrow therapeutic range are excluded from the study unless the subject can be transferred to other medications at least 5 halflives prior to the start of study treatment: paclitaxel and docetaxel (CYP2C8), phenytoin (CYP2C9), S-mephenytoin (CYP2C19), thioridazine (CYP2D6), theophylline, and tizanidine (CYP1A2).
19. Subject has any significant medical condition, laboratory abnormality, or psychiatric illness that places the subject at unacceptable risk or would prevent the subject from participating in the study.
20. Subject has any condition that confounds the ability to interpret data from the study.
