Safety Study of AG-120 or AG-221 in Combination With Induction and Consolidation Therapy in Participants With Newly Diagnosed Acute Myeloid Leukemia (AML) With an IDH1 and/or IDH2 Mutation

A Phase 1, Multicenter, Open-Label, Safety Study of AG-120 or AG-221 in Combination With Induction Therapy and Consolidation Therapy in Patients With Newly Diagnosed Acute Myeloid Leukemia With an IDH1 and/or IDH2 Mutation

The purpose of this Phase I, multicenter, clinical trial is to evaluate the safety of AG-120 and AG-221 when given in combination with standard AML induction and consolidation therapy. The study plans to evaluate up to 2 dose levels of AG-120 in participants with an isocitrate dehydrogenase protein 1 (IDH1) mutation and up to 2 dose levels of AG-221 in participants with an isocitrate dehydrogenase protein 2 (IDH2) mutation. AG-120 or AG-221 will be administered with 2 types of AML induction therapies (cytarabine with either daunorubicin or idarubicin) and 2 types of AML consolidation therapies (mitoxantrone with etoposide [ME] or cytarabine). After consolidation therapy, participants may continue on to maintenance therapy and receive daily treatment with single-agent AG-120 or AG-221 until relapse, development of an unacceptable toxicity, or hematopoietic stem cell transplant (HSCT). The study will end when all participants have discontinued study treatment.

A legally authorized representative may consent on behalf of a participant who is otherwise unable to provide informed consent, if acceptable to, and approved by, the site's Institutional Review Board (IRB)/Independent Ethics Committee (IEC).
• Female participants with reproductive potential must agree to undergo a medically supervised pregnancy test prior to starting study drug. The first pregnancy test will be performed at screening (within 7 days prior to first study drug administration). A pregnancy test should also be performed on the day of the first study drug administration and confirmed negative prior to dosing as well as before dosing on Day 1 of all subsequent cycles
• Female participants with reproductive potential must have a negative serum pregnancy test within 7 days prior to the start of the therapy. Participants with reproductive potential are defined as sexually mature women who have not undergone a hysterectomy, bilateral oophorectomy or tubal occlusion or who have not been naturally postmenopausal for at least 24 consecutive months. Females of reproductive potential as well as fertile men and their partners who are female of reproductive potential must agree to abstain from sexual intercourse or to use one highly effective form (for participants receiving AG-221) or two highly effective forms (for participants receiving AG-120) of contraception from the time of giving informed consent, during the study, and for 2 months (for participants receiving AG-221) and for 4 months (for participants receiving AG-120) following the last dose of AG-120 or AG-221 (females and males). A highly effective form of contraception is defined as hormonal oral contraceptives, injectables, patches, intrauterine devices, double-barrier method (e.g., synthetic condoms, diaphragm or cervical cap with spermicidal foam, cream, or gel) or male partner sterilization

• 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; myocardial infarction, unstable angina and/or stroke; or left ventricular ejection fraction (LVEF) <40% by echocardiogram (ECHO), or by other methods according to institutional practice, obtained within 28 days prior to the start of study treatment
• QTc interval using Fridericia's formula (QTcF) ≥450 milliseconds (msec) or other factors that increase the risk of QT interval prolongation or arrhythmic events (e.g., heart failure, hypokalemia, family history of long QT interval syndrome). Bundle branch block and prolonged QTc are permitted with approval of the study Sponsor
• Taking medications that are known to prolong the QT interval unless they can be transferred to other medications within ≥5 half-lives prior to dosing (If equivalent medication is not available QTc will be closely monitored)
• Known infection caused by human immunodeficiency virus (HIV) or active hepatitis B or C
• Dysphagia, short-gut syndrome, gastroparesis, or other conditions that limit the ingestion or gastrointestinal absorption of orally administered drugs
• Clinical symptoms suggestive of active central nervous system (CNS) leukemia or known CNS leukemia. Evaluation of cerebrospinal fluid (CSF) during screening is required only if there is a clinical suspicion of CNS involvement by leukemia during screening.
• Immediate life-threatening, severe complications of leukemia such as uncontrolled bleeding, pneumonia with hypoxia or shock, and/or disseminated intravascular coagulation
• Any other medical or psychological condition deemed by the Investigator to be likely to interfere with a participant's ability to give informed consent or participate in the study
