Detailed Description

This study is to evaluate the relative pharmacokinetics of oral decitabine and tetrahydrouridine (THU) after a high-fat, high-calorie (FDA standard) meal as compared to decitabine and THU under fasting conditions in healthy adult male and female subjects. In addition, this study is to compare the pharmacokinetic parameters between male and female subjects, and also to capture safety information for the decitabine and THU combination in healthy subjects after oral dosing.

  • Decitabine plasma concentration
    • Time Frame: 24 hours
    • Maximum concentration (Cmax) of Decitabine in plasma
  • Absorption of Tetrahydrouridine
    • Time Frame: 24 hours

  • Able to communicate with the investigator, and to understand and comply with the requirements of the study.
  • A healthy male or female from any race between 18 to 50 years of age (inclusive). If female, she meets at least one of the following criteria: Surgically sterile (hysterectomy, tubal ligation or bilateral oophorectomy); Or ≥1 year postmenopausal (will have a follicle-stimulating hormone test performed at screening to confirm postmenopausal status)
  • A body mass index (BMI) between 18 and 30 kg/m2 (inclusive) and a minimum weight of 50 kg at screening.
  • Subjects must be free of any clinically significant disease that would interfere with the study evaluations, and be in good health as determined by past medical history, physical examination, and ECG at screening.
  • Vital signs (systolic and diastolic blood pressure and pulse rate) will be assessed in the supine position after the subject has rested for at least 5 minutes. At screening, the potential subject must be afebrile, with a systolic blood pressure between 90 and 140 mmHg (inclusive), diastolic blood pressure between 60 and 90 mmHg (inclusive), and pulse rate between 50 and 100 bpm (inclusive).
  • Male subjects (including those who have had a documented vasectomy) must use a double-barrier local contraception (i.e., spermicidal gel plus condom) when engaging in sexual activity with women of childbearing potential while on study medication and for 28 days after the last dose of study medication. They must also agree to refrain from sperm donations while on study drug, for the entire duration of the study, and for at least 28 days after the last dose of study drug.

Exclusion Criteria

  • History (within 3 years prior to screening) or presence of clinically significant cardiovascular, pulmonary, hepatic, renal, hematologic, gastrointestinal, endocrine, immunologic, dermatologic, neurologic, oncologic, or psychiatric disease or any other condition, including the presence of laboratory abnormalities, that, in the opinion of the Investigator, would jeopardize the safety of the subject or the validity of the study results.
  • Any serious medical condition, clinically significant laboratory abnormality, or psychiatric illness that would prevent the subject from signing the Informed Consent Form.
  • Used any prescribed systemic or topical medication within 30 days of the first dose administration.
  • Used any non-prescribed systemic (including herbal medicines, e.g. St. John's Wort) or topical medication within 7 days of the first dose administration (with the exception of vitamin/mineral supplements)
  • Subjects who have any surgical or medical conditions possibly affecting drug absorption, distribution, metabolism and excretion (ADME), including a past cholecystectomy.
  • Exposed to an investigational drug (new chemical entity) within 90 days preceding the first dose administration or currently enrolled in any investigational trials.
  • Donated blood or plasma within 8 weeks preceding the first dose administration.
  • History of multiple drug allergies.
  • Any clinically significant allergic disease (excluding nonactive hayfever).
  • History of drug abuse within 2 years prior to dosing, or a positive drug test at screening or either check-in.
  • History of alcohol abuse within 2 years prior to dosing, or a positive alcohol test at screening or either check-in.
  • Smokers or users of other tobacco products (e.g., chewing tobacco, or those using nicotine-containing products (i.e., patches, gum) within 3 months prior to screening, or a positive urine cotinine test at screening or either check-in.
  • Known to have serum hepatitis or known to be a carrier of the hepatitis B surface antigen (HBsAg) or hepatitis C antibody, or tests positive for HIV (human immunodeficiency virus) antibodies at screening.
  • Subject must not consume beverages and foods containing grapefruit, broccoli, poppy seeds, Brussels sprouts, pomegranate, star fruit, char-grilled meat, or caffeine/xanthine from 48 hours prior to the first dose of study medication until the end-of-study visit. Subjects will be instructed not to consume any of the above products; however, allowance for an isolated single incidental consumption may be evaluated and approved by the study investigator based on the potential for interaction with the study drug.
