- Brief Summary
The main aim is to see if soticlestat has any effect in the heart rate.
Participants will receive 4 doses of soticlestat in tablets and will complete some assessment which include to record activity of the heart and collection of blood samples.
Then, the clinic will contact the participants 14 days after their final dose of soticlestat to check if they have any health problems.
- Detailed Description
The drug being tested in this study is called soticlestat. Soticlestat is being tested in healthy participants for the purpose of this study. This study will assess the effect of single-dose of soticlestat on the heart rate (QTc prolongation). The study will enroll approximately 60 participants.
Participants will be randomly assigned (by chance, like flipping a coin) to 1 of the 4 treatments sequences.
* Sequence 1: (Regimen A+ Regimen B + Regimen C + Regimen D)
* Sequence 2: (Regimen B+ Regimen D + Regimen A + Regimen C)
* Sequence 3: (Regimen C+ Regimen A + Regimen D + Regimen B)
* Sequence 4: (Regimen D+ Regimen C + Regimen B + Regimen A)
All participants will receive all 4 treatment regimens. Treatment order will remain undisclosed to the participants and study doctor (unless there is an urgent medical need). This is a single-center trial. Participants will be followed up for up to 14 days after the last dose of study drug for a follow-up assessment. The overall time to participate in this study is approximately 63 days including screening period and follow-up period.

- Primary Outcome Measures
Name Time Method Placebo-corrected Change From Baseline in Corrected QT Interval (QTc) Day -1 up to 24 hours post-dose The QTc interval will be measured by continuous electrocardiogram (ECG) recordings. The primary QT correction method will be Fridericia's correction. In case a substantial HR effect is observed on-treatment with soticlestat, drug-free QT/RR data will be collected over a range of Heart Rate (HR) seen off-treatment to allow the generation of individualized QT correction methods. QTc will be calculated from Day -1 of the first treatment period both during the periods of supine rest (QTcS) and from all evaluable QT/RR pairs in the 24-hour recording (QTcI). The method that removes the HR dependence of the QT interval most efficiently will be chosen as primary correction method. The analysis for QTc will be based on a linear mixed-effects model with ΔQTc as the dependent variable, period, sequence, time (that is, nominal post-dose time point), treatment, and time-by-treatment interaction as fixed effects, and baseline QTc as a covariate.
