Who can take part
You may be able to join if
- 1. Be ≥18 years of age and meet at least 1 of the following criteria defining ineligibility for intensive induction chemotherapy (IC): a. ≥ 75 years old b. ECOG PS = 2 c. Severe cardiac disorder (eg, congestive heart failure requiring treatment, LVEF ≤50%, or chronic stable angina) d. Severe pulmonary disorder (eg, diffusing capacity of the lungs for carbon monoxide ≤65% or forced expiratory volume in 1 second ≤65%) e. Creatinine clearance <45 mL/minute f. Bilirubin >1.5 times upper limit of normal (× ULN) g. Any other comorbidity that the Investigator judges to be incompatible with intensive IC must be reviewed and approved by the Medical Monitor before study enrollment.
- 10. If female with reproductive potential, must have a negative serum pregnancy test prior to the start of study therapy. Female subjects 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 with female partners of reproductive potential, must use 2 effective forms of contraception (including at least 1 barrier form) from the time of giving informed consent throughout the study and for 90 days (both females and males) following the last dose of study drug(s). Effective forms of contraception are defined as hormonal oral contraceptives, injectables, patches, intrauterine devices, intrauterine hormone-releasing systems, bilateral tubal ligation, condoms with spermicide, or male partner sterilization. Coadministration of AG-120 may decrease the concentrations of hormonal contraceptives.
- 2. Have previously untreated AML, defined according to World Health Organization criteria. Subjects with extramedullary disease alone (ie, no detectable bone marrow and no detectable peripheral blood AML) are not eligible for the study.
- 3. Have an IDH1 mutation resulting in an R132C, R132G, R132H, R132L, or R132S substitution, as determined by central laboratory testing (using an investigational polymerase chain reaction [PCR] assay, Abbott RealTime IDH1) in their bone marrow aspirate (or peripheral blood sample if bone marrow aspirate is not available, with Medical Monitor approval). (Note: Local testing for eligibility and randomization is permitted with Medical Monitor approval; however, results must state an IDH1 mutation resulting in an R132C, R132G, R132H, R132L, or R132S substitution. Bone marrow aspirate [or peripheral blood sample if bone marrow aspirate is not available, with Medical Monitor approval] for central laboratory testing must have been sent with proof of shipment to the central laboratory prior to randomization.)
- 4. Have an ECOG PS score of 0 to 2.
- 5. Have adequate hepatic function, as evidenced by: a. Serum total bilirubin ≤2 × ULN, unless considered to be due to Gilbert’s disease or underlying leukemia, where it must be <3 × ULN. b. Aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP) ≤3.0 × ULN, unless considered to be due to underlying leukemia.
You likely can't join if
- 1. Are candidates for intensive IC for their AML.
- 10. Have an active, uncontrolled, systemic fungal, bacterial, or viral infection without improvement despite appropriate antibiotics, antiviral therapy, and/or other treatment.
- 11. Have a prior history of malignancy other than MDS or myeloproliferative disorder, unless the subject has been free of the disease for ≥1 year prior to the start of study treatment. However, subjects with the following history/concurrent conditions or similar indolent cancer are allowed to participate in the study: a. Basal or squamous cell carcinoma of the skin b. Carcinoma in situ of the cervix c. Carcinoma in situ of the breast d. Incidental histologic finding of prostate cancer
- 12. Have had significant active cardiac disease within 6 months prior to the start of study treatment, including New York Heart Association Class (NYHA) Class III or IV congestive heart failure, myocardial infarction, unstable angina, and/or stroke.
- 13. Have a heart-rate corrected QT interval using Fridericia’s method (QTcF) ≥470 msec or any other factor that increases the risk of QT prolongation or arrhythmic events (eg, NYHA Class III or IV congestive heart failure, hypokalemia, family history of long QT interval syndrome). Subjects with prolonged QTcF interval in the setting of bundle branch block may participate in the study.
- 14. Have a known infection caused by human immunodeficiency virus or active hepatitis B virus (HBV) or hepatitis C virus that cannot be controlled by treatment.
