Subjects must fulfill all of the following inclusion criteria:;1. Male or female subjects, >=18 years of age at Screening;2. Body Mass Index (BMI) of 19.0 to 32.0 kg/m2, inclusive. Weight of at least 50 kg;3. For subjects with AML, MDS only:;a. Cytologically or histologically confirmed diagnosis of AML (except M3 acute promyelocytic leukemia) or MDS according to the 2008 World Health Organization (WHO) classification with the disease being refractory, relapsed, or unresponsive to standard treatment;b. Platelets >= 75,000/mm3;c. Absolute neutrophil count (ANC) >= 1000 cells/mm3;4. For subjects with solid tumors only:;a. Cytologically or histologically confirmed advanced solid tumor that is metastatic or unresectable, and for whom standard life-prolonging measures are not available.;b. Platelets >= 100,000/mm3;c. Absolute neutrophil >= 100 cells/mm3;5. Subjects with life expectancy of at least 16 weeks;6. Subjects with Eastern Cooperative Oncology Group (ECOG) performance status of 0-2;7. Subjects with acceptable organ function, as evidenced by laboratory data:;a. Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) < 3x upper limit of normal (ULN);b. Total serum bilirubin <= 2 mg/dL (<= 35 µmol/L);c. Serum creatinine levels <= 1.25x ULN OR calculated by Cockcroft-Gault formula >=50 mL/min;d. International normalized ratio (INR) <=2.3;8. Subjects who sign an approved informed consent form for the study;9. Subjects who are willing and able to comply with the protocol and study procedures, in particular willingness to undergo hospitalization and collection of blood and excreta after treatment with radiolabeled guadecitabine;10. Female subjects may be enrolled if they are:;a. documented to be surgically sterile or postmenopausal (amenorrhea >1 year and/or FSH >=40 mU/mL);or;b. practicing true abstinence for at least 28 days prior to dosing and agreeing to continue until 3 months after last study drug administration and having a negative urine pregnancy test at Screening and Day -1. Abstinence is acceptable only if it is consistent with the preferred and usual lifestyle of the subject. Periodic abstinence (eg, calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not acceptable methods of birth control.;or;c. using 2 forms of highly effective contraception, out of which one should be a physical barrier (condom or diaphragm or cervical cap with spermicidals), and another method such as adequate hormonal method (e.g. contraceptive implants, injectables, oral contraceptives) or non-hormonal methods (e.g. intrauterine device [IUD]) from Screening or at least 28 days prior to study drug administration (whichever is earlier) until 3 months after the last study drug administration and having a negative urine pregnancy test at Screening and Day -1. Contraceptive measures which may be considered highly effective comprise combined hormonal contraception (oral, vaginal, or transdermal) or progestogen-only hormonal contraception (oral, injectable, implantable) associated with inhibition of ovulation, IUD, or intrauterine hormone-releasing system.;11. Males with partners of childbearing potential may be enrolled if they:;a. are documented to be surgically sterile (vasectomy) for at least 6 months before study drug administration;or;b. agree to practice true abstinence for at least 3 months after the last study drug administration (see also Inclusion Criterion 10b);or;c. agree to use 2 adequate forms of highl
Subjects meeting any of the following exclusion criteria will be excluded from the study:;1. Subjects who have known hypersensitivity to guadecitabine or decitabine;2. Subjects who have received radiation therapy, other locoregional therapy, or chemotherapy within 4 weeks prior to the first dose of study drug. Subjects must have recovered from any significant toxicities associated with previous therapies.;3. Subjects who have previously participated in human ADME studies and treated with radiolabeled drug.;4. Subjects who are at poor medical risk because of other systemic diseases or active uncontrolled infections;5. Subjects with a life-threatening illness, medical condition or organ system dysfunction, or other reasons which, in the Investigator*s opinion, could compromise the subject*s safety, interfere with the metabolism of guadecitabine, or compromise the integrity of the study outcomes;6. Subjects with abnormal left ventricular ejection fraction (<50%) on echocardiogram or multiple-gated acquisition scan (MUGA);7. Subjects with uncontrolled ischemic heart disease or a history of congestive cardiac failure of >=Grade 3 severity according to New York Heart Association (NYHA);8. Subjects with active hepatitis B infection should be on adequate antiviral therapy;9. Subjects with prior malignancy, except for adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer, non-metastatic prostate cancer with normal prostate specific antigen (PSA) or other cancer from which the subject has been disease free for at least three years;10. Subjects with known history or active disease of human immunodeficiency virus (HIV) or hepatitis B or hepatitis C (HCV), unless there is evidence for cured hepatitis C;11. History of alcohol abuse or drug addiction (including soft drugs like cannabis products);12. Average intake of more than 24 units of alcohol per week for male subjects and 17 units per week for female subjects (1 unit of alcohol equals 10 mL of pure alcohol, i.e. approximately 250 mL of beer, 75 mL of wine or 25 mL of spirits);13. Participation in a drug study within 60 days prior to first study drug administration in the current study;14. Donation or loss of more than 500 mL of blood within 60 days prior to the first study drug administration.;15. Women of child-bearing potential must not be pregnant or breastfeeding and must have a negative pregnancy test at screening.
