Who can join

Age: 60 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Written informed consent.
• Either de novo or secondary AML by 2008 World Health Organization (WHO) classification.
• A bone marrow biopsy and aspirate sample must be obtained between Day -14 to Day -1, and this sample must be confirmed to be adequate for morphologic analysis of marrow cellularity and blast percentage before the first dose of KX2-391 is administered.
• A bone aspirate sample (with or without biopsy) must be obtained after the patient signs the informed consent document and be submitted for baseline pharmacodynamic assessment. Although this will usually be obtained as part of the baseline assessment marrow biopsy and aspirate procedure described above, if a complete marrow evaluation was performed prior to the patient signing informed consent, a dedicated bone marrow aspiration for this sample can be performed after the patient signs informed consent, so long as the pre-consent biopsy and aspirate procedure were done within 14 days of the first dose of KX2-391.
• Adults age ≥ 60 years of age
• Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2
• Life expectancy of at least 6 weeks from first day of study drug administration
• Adequate liver function (AST/ALT < 3 x upper limit of normal (ULN), Alk Phos < 2.5 x ULN, and Direct Bilirubin < 1.5 x ULN)
• Adequate renal function (serum creatinine < 1.5 x ULN)
• Documented QTc ≤ 0.48 seconds within 14 days of first dose of KX2-391

You may not qualify if…

• Subjects with acute promyelocytic leukemia (APL, AML FAB type M3), or chronic myelogenous leukemia (CML).
• Have not resolved toxicity from previous anticancer treatments or investigational agents, other than hematologic toxicities or alopecia, to ≤ Grade 1 according to the most recent CTCAE guidelines.
• Subjects with rapidly proliferative AML that is likely to require treatment within the next 30 days (e.g. hydroxyurea).
• Received an investigational agent within 5 half-lives of that agent from the anticipated Cycle 1 Day 1 of treatment with KX2-391.
• Have clinical evidence of central nervous system involvement by AML or other malignancy.
• History of major surgery to the upper gastrointestinal tract, or have a history of inflammatory bowel disease, malabsorption syndrome, or other medical condition that may interfere with oral drug absorption.
• Uncontrolled hypertension (at time of dosing).
• Other medical conditions which, in the opinion of the investigator, make it undesirable for the subject to participate in the study.
• Known history of hepatitis B, C, or human immunodeficiency (HIV) infection.
• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection. Patients receiving intravenous antibiotics for infections that are under control may be included in this study.
• Subjects who are unwilling or unable to comply with the protocol.
• Subjects who are taking moderate or strong CYP450 3A4 modulators, with the exception of fluconazole (see Appendix 2 for list of medications currently known to be moderate or strong CYP450 3A4 modulators). Subjects who can safely discontinue these medications can become eligible for this trial.
• Subjects receiving azole-based antifungal prophylaxis other than fluconazole (see Appendix 2) who are unable to switch their prophylaxis to fluconazole, or discontinue antifungal prophylaxis, for 7 days prior to first day of study drug administration.
• Active cancer, other than AML, requiring systemic chemotherapy or biological therapy within 6 months of study entry. Patients who have received only hormonal therapy in the neoadjuvant or adjuvant setting in the past 6 months may participate in this study.
• Symptomatic congestive heart failure, unstable angina, or cardiac arrhythmia.
• Other conditions that could jeopardize the subject's ability to comply with the protocol, including, but not limited to, dementia, psychosis, or other major psychiatric disorder
• Pregnant or breast feeding
