Decitabine and Selinexor in Treating Patients With Relapsed or Refractory Acute Myeloid Leukemia

Inclusion Criteria:

• Patients with relapsed or refractory AML
• Newly diagnosed elderly AML patients (> 60 years) unfit for intensive chemotherapy with cytarabine and anthracyclines are also eligible to this trial given that no clinically beneficial therapy exists for these patients
• Patients with secondary AML or therapy related disease (t-AML) are eligible; patients who received decitabine or 5-azacytidine as prior treatment for myelodysplastic syndrome (MDS) or AML remain eligible; however, none of these agents is permitted within 6 months of study entry
• If the patient has co-morbid medical illness, life expectancy attributed to this must be greater than 6 months
• Eastern Cooperative Oncology Group (ECOG) performance status < 2
• Total bilirubin < 2.0 mg/dL
• Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) < 2.5 X institutional upper limit of normal
• Creatinine < 2.0 mg/d
• Glomerular filtration rate (GFR) > 50 mL/min
• New York Heart Association (NYHA) congestive heart failure (CHF) class II or better
• Female patients of child-bearing potential must agree to use dual methods of contraception and have a negative serum pregnancy test at screening, and male patients must use an effective barrier method of contraception if sexually active with a female of child]bearing potential; acceptable methods of contraception are condoms with contraceptive foam, oral, implantable or injectable contraceptives, contraceptive patch, intrauterine device, diaphragm with spermicidal gel, or a sexual partner who is surgically sterilized or post-menopausal; for both male and female patients, effective methods of contraception must be used throughout the study and for three months following the last dose
• Ability to understand and willingness to sign the written informed consent document
• Human immunodeficiency virus (HIV) infection without history of acquired immune deficiency syndrome (AIDS) and sufficiently high cluster of differentiation (CD)4 cells (> 400/mm^3) and low HIV viral loads (< 30,000 copies/ml plasma) not requiring anti-HIV therapy are eligible
• Patients must have recovered from the toxicity of prior therapy to less than grade 2

Exclusion Criteria:

• Patients who have had chemotherapy or radiotherapy within 2 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study
• Patients receiving any other investigational agents or patients that have received other investigational agents within 14 days of enrollment
• Patients with active central nervous system (CNS) malignancy; asymptomatic small lesions are not considered active; treated lesions may be considered inactive if they are stable for at least 3 months; patients with malignant cells in their cerebrospinal fluid (CSF) without CNS symptoms may be included
• Patients with history of allergic reactions attributed to compounds of similar chemical or biologic composition to decitabine that are not easily managed
• Major surgery within 2 weeks before day 1
• Uncontrolled active infection requiring parenteral antibiotics, antivirals, or antifungals within one week prior to first dose
• Known active hepatitis A, B, or C infection; or known to be positive for hepatitis C virus (HCV) ribonucleic acid (RNA) or HBsAg (hepatitis B virus [HBV] surface antigen)
• Patients with significantly diseased or obstructed gastrointestinal tract or uncontrolled vomiting or diarrhea
• History of seizures, movement disorders or cerebrovascular accident within the past 3 years prior to cycle 1 day 1
• Patients with macular degeneration, uncontrolled glaucoma, or markedly decreased visual acuity
• Uncontrolled intercurrent illness including, but not limited to, symptomatic congestive heart failure (New York Heart Association [NYHA] class III or IV), unstable angina pectoris, myocardial infarction within 6 months prior to enrollment, severe uncontrolled ventricular arrhythmias, or electrocardiographic evidence of acute ischemia or active conduction system abnormalities; prior to study entry, any electrocardiogram (ECG) abnormality at screening has to be documented by the investigator as not medically relevant
• Patients with serious medical or psychiatric illness likely to interfere with participation in this clinical study
• Pregnant women or women who are breastfeeding are excluded from this study; confirmation that the subject is not pregnant must be established by a negative serum beta-human chorionic gonadotropin (beta-hCG) pregnancy test result obtained during screening; pregnancy testing is not required for post-menopausal or surgically sterilized women
• Patients with advanced malignant solid tumors are excluded
• Patients with renal failure (GFR < 50 mL/min) are excluded
• Patients that in the opinion of the investigators are significantly below their ideal body weight
