Brief summary
The enzyme responsible for the conversion of elafibranor into its active metabolite, GFT1007, has not been formally identified, but it is believed to have similar characteristics to an α,β-ketoalkene reductase previously identified in rat liver cytosol. In vitro studies in human liver cytosol fractions have shown that indomethacin inhibits the enzyme responsible of the transformation of elafibranor into GFT1007. As a result, indomethacin was included in the list of prohibited co-medications in all clinical trials with elafibranor, and a formal Drug-Drug Interaction (DDI) clinical study is being conducted to elucidate the effect of indomethacin on elafibranor pharmacokinetics.

Provide written informed consent prior to the conduct of any study related procedures; 2. Healthy Caucasian male participant, aged between 18 and 50 years (inclusive); 3. Non-smoker participant or smoker of not more than 5 cigarettes a day within one year prior to Inclusion visit; 4. Body Mass Index (BMI) between 19 and 28 kg/m² and Body Weight (BW) not lower than 55 kg at both Screening visit and Inclusion visit; 5.

Out-of-range values that are not clinically significant, as determined by the Investigator, may be repeated twice and the participant may be enrolled if at least 1 repeated value is within the specified ranges; 7.

Out-of-range values that are not clinically significant (as determined by the Investigator) may be repeated twice during Screening and Inclusion visits, and the participant may be enrolled if at least 1 repeated value is within the specified normal ranges; 8. Laboratory parameters within the normal range of the laboratory (haematological, blood chemistry tests, urinalysis) at Screening and Inclusion visits. Individual values out of the normal range can be accepted if judged clinically non relevant by the Investigator; 9. Participant with normal dietary habits; 10. Covered by Health Insurance System and in compliance with the recommendations of National Law in force relating to biomedical research.

Receipt of blood products within 2 months prior to Inclusion visit; 8. General anesthetics within the 3 months prior to first administration; 9. History or presence of any allergy or unusual reactions to drugs or anesthetics or known hypersensibility to the investigational products (elafibranor and/or CHRONO-INDOCID®) or their excipients; 10. Any medication that may interfere with study medications absorption, distribution, metabolism or excretion or could lead to induction or inhibition of microsomial enzymes within 3 months prior to first administration; 11. Any drug intake (except paracetamol 3g/d) during the last month prior to inclusion; 12. A positive alcohol test result or urine screen for drugs of abuse result at Screening or Inclusion visits; 13. Any history or suspicion of consumption of any drug of abuse (amphetamines, barbiturates, benzodiazepines, cannabis, cocaine, methamphetamines, methadone, methylenedioxymethamphetamine (MDMA), opiates, tricyclic antidepressant) or alcohol (alcohol consumption \> 40 grams/day), from Screening to end of the study; 14. Consumption of nutritional supplements, herb-containing drug preparations (including Chinese medicines) or other foods or beverages (e.g., grapefruit and xanthine-containing foods or beverages) that may affect drug-metabolizing enzymes or transporters within 48 hours before Inclusion visit and until end of study visit; 15. Positive for hepatitis B or hepatitis C, or positive results for HIV 1 or 2 tests; 16. Participant unable to abstain from intensive muscular effort; 17. Participant who, in the judgment of the Investigator, is likely to be non-compliant or uncooperative during the study, or unable to cooperate because of a language problem, poor mental development; 18. Participant in the exclusion period of a previous study; 19. Participant who, considering the indemnities of the present study, would have received more than 4500 Euros for his participation in biomedical research within the 12 last months, including the indemnities for the present study; 20. Participant who cannot be contacted in case of emergency; 21. Participant with no legal capacity or limited legal capacity or unable to give an informed consent.
