A Study to Evaluate the Effects of E2609 on QTc Interval in Healthy Subjects
Study Details
Study Description
Brief Summary
This thorough QT (TQT) study will take place in healthy subjects administered single doses of study drug. It will be a randomized, double-blind, placebo and active-controlled, 4-treatment crossover study. Subjects will be randomized in an equal ratio to one of 12 possible treatment sequences. Each treatment sequence will comprise all 4 treatments.

Phase 1 |
Detailed Description
The study will consist of 2 phases: Prerandomization and Randomization. The Prerandomization Phase will have 2 periods: Screening (up to 27 days) and Baseline Period 1 (1 day). Eligibility will be determined during the Screening Period. The Randomization Phase will consist of 8 periods: Treatment Period 1, Baseline Period 2, Treatment Period 2, Baseline Period 3, Treatment Period 3, Baseline Period 4, Treatment Period 4, and a Follow-Up Period. Each Baseline Period will last 1 day, followed by the corresponding treatment period. On the first day of each treatment period, subjects will receive a single dose of the assigned study drug. During each treatment period, subjects will be required to stay in the clinical unit from the baseline period to 24 hours postdose. Subjects will then be released from the clinic and will undergo a washout interval of at least 13 days, during which time they will return for additional PK sampling.

Outcome Measures
Primary Outcome Measures
- Change from baseline in QTcF obtained from ECGs extracted from the Holter recordings [Up to 24 hours postdose during each treatment period]
Holter recordings are taken from a portable device for continuously monitoring various electrical activity of the cardiovascular system for at least 24 hours. Baseline is defined as the mean of predose QTcF values obtained from ECGs extracted from Holter recordings before dosing during each treatment period.
Secondary Outcome Measures
- Change from baseline in ECG recordings: PR interval [Predose and then up to 24 hours postdose in each treatment period]
Electrocardiograms will be extracted from the continuous digital recording at 3 predose time points. Other time points may be evaluated as well.
- Change from baseline in ECG recordings: QRS interval [Predose and then up to 24 hours postdose in each treatment period]
Electrocardiograms will be extracted from the continuous digital recording at 3 predose time points. Other time points may be evaluated as well.
- Change from baseline in ECG recordings: HR [Predose and then up 24 hours postdose in each treatment period]
Electrocardiograms will be extracted from the continuous digital recording at 3 predose time points. Other time points may be evaluated as well.
- Change from baseline in ECG recordings: RR interval [Predose and then at up to 24 hours postdose in each treatment period]
Electrocardiograms will be extracted from the continuous digital recording at 3 predose time points. Other time points may be evaluated as well.
- Change from baseline in ECG recordings: T wave morphology [Predose and then at up to 24 hours postdose in each treatment period]
Electrocardiograms will be extracted from the continuous digital recording at 3 predose time points. Other time points may be evaluated as well.

Eligibility Criteria
Criteria
Inclusion Criteria
Subjects must meet all of the following criteria to be included in this study:
-
Healthy, non-smoking, male or female subjects ages greater than or equal to 18 years to less than or equal to 55 years old at the time of informed consent
-
Body mass index (BMI) of greater than or equal to 18 to less than or equal to 30 kg/m2 at Screening
-
Females must not be lactating or pregnant at Screening or Baseline (as documented by a negative betahuman chorionic gonadotropin [B-hCG]). A separate baseline assessment is required if a negative screening pregnancy test was obtained more than 72 hours before the first dose of study drug.
-
Females of childbearing potential must not have had unprotected sexual intercourse within 30 days before study entry and must agree to use a highly effective method of contraception (eg, total abstinence, an intrauterine device, a double-barrier method [such as condom plus diaphragm with spermicide], or have a vasectomized partner with confirmed azoospermia, but not oral contraceptive or contraceptive implant) throughout the entire study period and for 30 days after study drug discontinuation. If currently abstinent, the subject must agree to use a double barrier method as described above if she becomes sexually active during the study period or for 30 days after study drug discontinuation. Hormonal contraceptives (oral or implant) are not permitted forms of contraception in this study. 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 (ie, bilateral tubal ligation, total hysterectomy or bilateral oophorectomy, all with surgery at least one month before dosing).
