Study to Compare the Level of Elafibranor in Blood After Repeat Administration in Japanese and Non-Asian Healthy Participants

This study is intended to measure the blood levels of Elafibranor and one of its metabolites in Japanese and non-Asian Healthy Participants, to be able to compare how the body absorbs, distributes, and eliminates Elafibranor after Repeat Administration, in order to support inclusion of Japanese patients in the planned clinical studies with elafibranor.


Eligibility Criteria:
Inclusion Criteria :

* Participants should meet one of the following ethnicity criteria:

  1. Japanese:

     * Must have been born in Japan.
     * Both the subject's biological parents and all four biological grandparents must be Japanese, as confirmed by interview.
     * Must not be living outside of Japan for more than 10 years.
     * Lifestyle, including diet, has not changed significantly since leaving Japan
  2. Non-Asian:

     * Must be a descent from North America, South America, Europe or the Middle East (subjects from Asian/Pacific Islander and African American descent are excluded).
     * Both the subject's biological parents and all four biological grandparents must be of non-Asian descent
* Male or female participants must be 18 to 55 years of age (inclusive) at the time of signing the informed consent. A minimum of six evaluable subjects of each sex will have to be completed within each cohort (i.e. at least six female and six male subjects)
* Has provided signed informed consent, which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol
* Willingness to remain at the clinic for the required duration and willingness to return to the clinic for the follow-up evaluation as specified in the protocol
* Healthy participants as determined by medical evaluation at the screening visit including medical history, physical examination, laboratory tests, electrocardiogram (ECG) and vital signs monitoring
* Laboratory parameters within the normal range of the laboratory (haematological, blood biochemistry, urinalysis). Individual values out of the normal range can be accepted if judged non-clinically significant by the investigator.
* Normal ECG recording on a 12-lead ECG at screening and at admission (Day -1):

  * 120≤PR≤220 ms,
  * QRS\<110 ms,
  * QTcF≤430 ms for male and ≤450 ms for female,
* No evidence of sinus node automaticity or abnormal conduction, or rhythm disorders of concern, except as considered non-clinically significant by the investigator. Out-of-range values that are not clinically significant (as determined by the investigator) may be repeated twice during screening and admission and the participant may be enrolled if at least one repeated value is within the range noted above.
* Normal blood pressure (BP) and heart rate (HR) at the screening and at admission after 5 minutes in supine position:

  * 90 mmHg ≤ systolic blood pressure (SBP)≤145 mmHg
  * 50 mmHg ≤ diastolic blood pressure (DBP)≤90 mmHg,
  * 45 bpm≤HR≤90 bpm,
* For these parameters, out-of-range values that are not clinically significant (as determined by the investigator) may be repeated twice during screening and admission and the participant may be enrolled if at least one repeated value is within the range noted above.
* Body weight not below 45 kg and body mass index (BMI) within the range 18.0 kg/m\^2 and 30.0 kg/m\^2
* Contraception/Barrier Requirements:

  1. Female participants:

     * A female participant is eligible to participate if she is not pregnant or breastfeeding at screening, is willing not to become pregnant during the study and one of the following conditions applies:
     * Is a woman of nonchildbearing potential (WONCBP), or
     * Is a woman of childbearing potential (WOCBP) and using a contraceptive method that is highly effective (with a failure rate of \<1% per year), preferably with low user dependency, during the study intervention period and for at least one month after the last dose of study intervention. The investigator should evaluate the potential for contraceptive method failure (e.g. noncompliance, recently initiated) in relationship to the first dose of study intervention.
     * A WOCBP must have a negative highly sensitive pregnancy test (serum as required by local regulations) within 24 hours before dosing with study intervention. The investigator is responsible for review of medical history, menstrual history and recent sexual activity to decrease the risk for inclusion of a woman with an early undetected pregnancy.
  2. Male participants:

     * Male participants are eligible to participate if they agree to the following during the intervention period and for at least 90 days after the last dose of study intervention:
     * Refrain from donating sperm PLUS, either:
     * Be abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long term and persistent basis) and agree to remain abstinent, or
     * Must agree to use contraception /barrier as detailed below:
     * Agree to use a male condom and should also be advised of the benefit for a female partner to use a highly effective method of contraception as a condom may break or leak and there remains a risk to pregnant women and women of childbearing potential

Exclusion Criteria :

* History or presence of cardiovascular, respiratory, hepatic, renal, gastrointestinal, endocrinological, haematological or neurological disorders capable of significantly altering the absorption, metabolism or elimination of drugs; constituting a risk when taking the study intervention; or interfering with the interpretation of data
* Lymphoma, leukaemia or any malignancy within the past 5 years except basal cell or squamous epithelial carcinomas of the skin that have been resected with no evidence of metastatic disease for 3 years prior to screening
