Study to Evaluate the Effect of Diltiazem Extended Release on the Pharmacokinetics of E2027 in Healthy Subjects

Completed · Phase 1

Conditions studied: Healthy Subjects

In brief

This Phase 1, open-label, single-sequence, drug-drug Interaction study is conducted to evaluate the effect of diltiazem extended release (ER) (a moderate CYP3A inhibitor and P glycoprotein \[Pgp\] inhibitor) on the pharmacokinetics (PK) of a single oral dose of E2027 in healthy participants.

Who can join

Age: 18 and older, up to 50. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• Non-smoking, male or female participants, ≥18 years old and ≤50 years old at the time of informed consent
• Body mass index of 18 to 32 kilograms per meters squared (kg/m\^2) at Screening

You may not qualify if…

• Clinically significant illness that requires medical treatment within 8 weeks or a clinically significant infection that requires medical treatment within 4 weeks prior to the first dose
• Females who are: (a) breastfeeding; or (b) pregnant at Screening or Baseline (documented by a negative beta human chorionic gonadotropin [β-hCG] (or human chorionic gonadotropin [hCG]) test with a sensitivity of at least 25 International Units per Liter (IU/L) or equivalent units of β-hCG [or hCG]). Note: A negative urine pregnancy test is required before the administration of the first dose.
• Females of childbearing potential who:
• Had unprotected sexual intercourse within 30 days before study entry and do not agree to use a highly effective method of contraception (e.g., total abstinence, an intrauterine device, a double barrier method [such as condom plus diaphragm with spermicide] or have a vasectomized partner with confirmed azoospermia) throughout the entire study period and for 28 days after study drug discontinuation. Note: Hormonal contraceptives are not allowed.
• Are currently (for at least 30 days) abstinent, and do not agree to use a double barrier method (as described above) or refrain from sexual activity during the study period or for 28 days after study drug discontinuation NOTE: All females will be considered to be of childbearing potential unless they are postmenopausal (amenorrheic for at least 12 consecutive months, in the appropriate age group, and without other known or suspected cause) or have been sterilized surgically (i.e., bilateral tubal ligation, hysterectomy, or bilateral oophorectomy, all with surgery at least 1 month prior to first dose).
• Males who have not had a successful vasectomy (confirmed azoospermia) or they and their female partners do not meet the criteria above (i.e., not of childbearing potential or practicing highly effective contraception throughout the study period or for 28 days after study drug discontinuation). No sperm donation is allowed during the study period or for 28 days after study drug discontinuation.
• Evidence of disease that may influence the outcome of the study within 4 weeks prior to the first dose (e.g., psychiatric disorders and disorders of the gastrointestinal tract, liver, kidney, respiratory system, endocrine system, hematological system, neurological system, or cardiovascular system, or participants who have a congenital abnormality in metabolism)
• Any history of abdominal surgery that may affect pharmacokinetic profiles of E2027 (e.g., hepatectomy, nephrectomy, digestive organ resection). Participants with a history cholecystectomy or appendectomy are not excluded.
• Any other clinically abnormal symptom or organ impairment found by medical history, physical examinations, vital signs, electrocardiogram (ECG) finding (including a PR greater than 210 milliseconds (msec), a QRS greater than 110 msec), or laboratory test results that requires medical treatment at Screening or Baseline as determined by the Principal Investigator or designee
• A prolonged QT/QTc interval (QTc greater than 450 msec) demonstrated on ECG at Screening or Baseline (based on average of triplicate ECGs). A history of risk factors for torsade de pointes (e.g., heart failure, hypokalemia, family history of long QT Syndrome) or the use of concomitant medications that prolonged the QT/QTc interval
• Left bundle branch block at Screening or Baseline
• Persistent systolic blood pressure (BP) greater than 160 or less than 100 millimeters of mercury (mmHg) or diastolic BP greater than 100 or less than 50 mmHg at Screening or Baseline
• Persistent pulse rate less than 50 beats/minute (min) or more than 90 beats/min at Screening or Baseline
• History of myocardial infarction, ischemic heart disease, or cardiac failure at Screening
• History of clinically significant arrhythmia or uncontrolled arrhythmia
• Known history of clinically significant drug allergy at Screening or Baseline
• Participants with any contraindications to diltiazem Extended Release
• Known history of food allergies or presently experiencing significant seasonal or perennial allergy at Screening or Baseline
• Known to be human immunodeficiency virus (HIV) positive at Screening
• Active viral hepatitis (A, B, or C) as demonstrated by positive serology at Screening
• History of drug or alcohol dependency or abuse within the 2 years before Screening, or those who have a positive urine drug or alcohol test at Screening or Baseline
• Participants who smoke or have used tobacco or nicotine-containing products within 4 weeks prior to first dose
• A Columbia Suicide Severity Rating Scale (C-SSRS) suicidal ideation score of 4 or 5 at Screening or Baseline, or for the period within 6 months before Screening or Baseline, or any lifetime suicidal behavior
• Currently enrolled in another clinical trial or used any investigational drug or device within 30 days (or 5 half-lives, whichever is longer) preceding informed consent
• Engagement in strenuous exercise within 2 weeks prior to first dose (e.g., marathon runners, weight lifters)
