A Study to Evaluate the Pharmacokinetics of Entinostat in Adult Subjects With Normal and Impaired Renal Function

Completed · Phase 1

Conditions studied: Renal Impairment, Healthy Volunteer

In brief

This purpose of this study is to evaluate the effects of a single dose of entinostat on subjects with varying levels of renal impairment. The primary objective of this study is to evaluate the pharmacokinetics of a single dose of entinostat in adult subjects with mild, moderate and severe renal impairment compared to healthy mean-matched subjects. The secondary objective of this study is to evaluate the safety and tolerability of entinostat in adult subjects with mild, moderate, and severe renal impairment and in healthy mean-matched adult subjects.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• All Subjects:
• Adult male or female (of non childbearing potential only), at least 18 years of age, at screening.
• BMI ≥ 18.5 to ≤ 40.0 kg/m2, at screening.
• Subject is a non-smoker or moderate smoker (≤ 10 cigarettes/day or the equivalent). Subject must agree to consume no more than 10 cigarettes or equivalent/day from the time of screening and throughout the period of PK sample collection.
• Females must be of non childbearing potential and must have undergone one of the following sterilization procedures, and have official documentation, at least 6 months prior to dosing:
• hysteroscopic sterilization;
• bilateral tubal ligation or bilateral salpingectomy;
• hysterectomy;
• bilateral oophorectomy; or be postmenopausal with amenorrhea for at least 1 year prior to dosing and follicle-stimulating hormone (FSH) serum levels consistent with postmenopausal status as per PI or designee judgment.
• 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 dosing of study drug. (No restrictions are required for a vasectomized male provided his vasectomy has been performed 4 months or more prior to dosing of study drug. A male who has been vasectomized less than 4 months prior to dosing must follow the same restrictions as a non vasectomized male).
• If male, must agree not to donate sperm from dosing until 90 days after dosing of study drug.
• Understands the study procedures in the informed consent form (ICF) and be willing and able to comply with the protocol.
• Mild, Moderate, and Severe Renal Impaired Subjects:
• Baseline health is judged to be stable based on medical history, laboratory profiles, vital signs, or ECGs at screening, as deemed by the PI. Subjects with any clinical laboratory results outside normal ranges may be enrolled if deemed appropriate in the opinion of the PI.
• For subjects with mild RI only: Baseline eGFR 60 89 mL/min/1.73m2, inclusive, based on the MDRD equation at screening defined as follows:
• eGFR = 175 x (Scr,std)-1.154 x (Age)-0.203 Scr, std: serum creatinine (mg/dL) measured with a standardized assay. For females, multiply result by 0.742; if African American, multiply result by 1.212.
• For subjects with moderate RI only: Baseline eGFR 30 - 59 mL/min/1.73m2, inclusive, based on the MDRD equation at screening as described above.
• For subjects with severe RI only: Baseline eGFR 29 mL/min/1.73m2 or less based on the MDRD equation at screening as described above.
• Subject has had no clinically significant change in renal status at least 1 month prior to study medication administration and is not currently or has not previously been on hemodialysis.
• Matched Healthy Control Subjects 8. Medically healthy with no clinically significant medical history, physical examination, laboratory profiles, vital signs or ECGs, as deemed by the PI or designee. Subjects with any clinical laboratory results outside normal ranges may be enrolled if deemed appropriate in the opinion of the PI.
• Has eGFR ≥ 90 mL/min/1.73m2, based on the MDRD equation at screening defined as follows: eGFR = 175 x (Scr,std)-1.154 x (Age)-0.203 Scr, std: serum creatinine (mg/dL) measured with a standardized assay. For females, multiply result by 0.742; if African American, multiply result by 1.212.
• Actual creatinine clearance, as determined by a 24-hour urine collection, may be used in place of or in conjunction with the MDRD equation, at the PI's discretion. Subjects who have an actual or estimated creatinine clearance up to 10% below 90 mL/min/1.73m2 may be enrolled in the study at the discretion of the PI.
• The age of individual healthy adult male and female subjects is aimed to be within the range of the mean age ± 10 years of the mild, moderate and severe RI subjects. In the event that these subjects do not match the mean for age in the severe RI cohort, additional healthy subjects (up to 8) will be enrolled using the same criteria.
• The BMI of individual healthy adult male and female subjects is aimed to be within the range of the mean BMI ± 20 % of the mild, moderate and severe RI subjects. In the event that these subjects do not match the mean for BMI in the severe RI cohort, additional healthy subjects (up to 8) will be enrolled using the same criteria.

You may not qualify if…

• All Subjects:
• 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.
• History or presence of clinically significant medical or psychiatric condition or disease in the opinion of the PI or designee.

• Any medication or substance (including prescription or over-the-counter, including herbal products, natural or herbal supplements) which cannot be discontinued at least 14 days prior to dosing and throughout the study. Subjects who are taking medications for stable diseases for at least \~2 weeks for subjects with severe RI or \~1 month for mild and moderate renal impaired subjects (or 5 half-lives of the compound, whichever is longer) prior to dosing will be allowed to participate in the study at the discretion of the PI and following consultation with the Sponsor Medical Monitor.

• Plasma donation within 7 days prior to dosing.
• Participation in another clinical study within 28 days prior to dosing. The 28 day window will be derived from the date of dosing.
