The purpose of this study is to evaluate the effect of Entinostat on the bioavailability of
Midazolam.
The primary objective is to evaluate the effect of a single oral dose of entinostat on the
pharmacokinetics (PK) of a single oral dose of midazolam in healthy subjects.
The secondary objective is to evaluate the safety and tolerability of combined administration
of entinostat and midazolam in healthy subjects.

Eligibility |
Inclusion Criteria: 1. 1. Healthy, adult, male or female (of non childbearing potential only), 19-55 years of age, inclusive, at screening. 2. Continuous non smoker who has not used nicotine containing products for at least 3 months prior to the first dose and throughout the study. 3. Body mass index (BMI) = 18.5 and = 32 kg/m2 at screening. 4. Medically healthy with no clinically significant medical history, physical examination, laboratory profiles, vital signs or ECGs, as deemed by the PI or designee. Liver function tests (serum alanine aminotransferase [ALT], aspartate aminotransferase [AST], alkaline phosphatase [ALP]) and serum bilirubin (total and direct) must be = the upper limit of normal at screening for inclusion. Platelets, hemoglobin and hematocrit must be = than the lower limit of normal at screening for inclusion. 5. For a female of non childbearing potential: must have undergone one of the following sterilization procedures, and have official documentation, at least 6 months prior to the first dose: - hysteroscopic sterilization; - bilateral tubal ligation or bilateral salpingectomy; - hysterectomy; - bilateral oophorectomy; or be postmenopausal with amenorrhea for at least 1 year prior to the first dose and follicle-stimulating hormone (FSH) serum levels consistent with postmenopausal status as per PI or designee judgment. 6. A non vasectomized, male subject must agree to use a condom with spermicide or abstain from sexual intercourse during the study until 90 days beyond the last dose of study drug. (No restrictions are required for a vasectomized male provided his vasectomy has been performed 4 months or more prior to first dose of study drug. A male who has been vasectomized less than 4 months prior to study first dose must follow the same restrictions as a non vasectomized male). 7. If male, must agree not to donate sperm from the first dose until 90 days after the last dose of study drug. 8. Understands the study procedures in the informed consent form (ICF), and be willing and able to comply with the protocol. Exclusion Criteria: 1. Subject is mentally or legally incapacitated or has significant emotional problems at the time of the screening visit or expected during the conduct of the study. 2. History or presence of clinically significant medical or psychiatric condition or disease in the opinion of the PI or designee. 3. History of any illness that, in the opinion of the PI or designee, might confound the results of the study or poses an additional risk to the subject by their participation in the study. 4. History or presence of alcoholism or drug abuse within the past 2 years prior to the first dose. 5. History or presence of hypersensitivity or idiosyncratic reaction to entinostat or drugs with a benzamide structure (e.g., tiapride, remoxipride, clebropride), midazolam, related compounds, or inactive ingredients. 6. History or presence of any of the following as deemed clinically significant in the opinion of the PI or designee: - Cancer (subject with history of cancer that is in complete remission and not requiring treatment for at least 5 years with the exception of basal cell carcinoma or cervical intraepithelial neoplasia/cervical carcinoma in situ or melanoma in situ superficial skin lesions that have been successfully removed will not be exclusionary); - Cardiovascular disorders; - Acute or chronic GI conditions (e.g., gastroesophageal reflux disease, peptic ulcer, colitis, gastric bypass or equivalent) that would interfere with drug tolerance or absorption. - Respiratory disease. 7. Evidence of active infection or febrile illness (e.g., GI, bronchopulmonary, or urinary) within 7 days prior to the first dose of study drug 8. Clinically significant infection within 3 months prior to dosing as determined by the PI or designee. 9. Positive urine drug or alcohol results at screening or check in. 10. Positive urine cotinine at screening. 11. Positive results at screening for human immunodeficiency virus (HIV), hepatitis B surface antigen (HBsAg) or hepatitis C virus (HCV). 12. Female subjects of childbearing potential. 13. Female subjects with a positive pregnancy test or lactating. 14. Seated blood pressure is less than 90/40 mmHg or greater than 140/90 mmHg at screening. 15. Seated heart rate is lower than 40 bpm or higher than 99 bpm at screening. 16. QTcB interval is >460 msec or has ECG findings deemed abnormal with clinical significance by the PI or designee at screening 17. Estimated creatinine clearance <90 mL/min at screening. 18. Unable to refrain from or anticipates the use of: - Any drug, including prescription and non prescription medications (including herbal products, or vitamin supplements) beginning 14 days prior to the first dose of study drug and throughout the study. Acetaminophen (up to 2 g per 24 hour period) may be permitted during the study; however acetaminophen will not be administered 4 hours before and after dosing. Thyroid hormone replacement medication may be permitted if subject has been on same stable dose for last 3 months prior to first study drug administration. - Any drugs known to be significant inducers of CYP enzymes and/or P gp, including St. John's Wort, for 28 days prior to the first dose and throughout the study. Appropriate sources will be consulted by the PI or designee to confirm lack of PK/pharmacodynamics interaction with study drug. 19. Has been on a diet incompatible with the on study diet, in the opinion of the PI or designee, within the 28 days prior to the first dose and throughout the study. 20. Donation of blood or significant blood loss within 56 days prior to the first dose. 21. Plasma donation within 7 days prior to the first dose. 22. Participation in another clinical study within 28 days prior to the first dose. The 28 day window will be derived from the date of the last blood collection or dosing, whichever is later, in the previous study to Day 1 of Period 1 of the current study. |
