A PHASE 1, OPENLABEL, SINGLECENTER STUDY TO EVALUATE DRUGDRUG INTERACTIONS WITH GEMFIBROZIL, ITRACONAZOLE, AND CARBAMAZEPINE AND THE FOOD-EFFECT ON ORAL LERIGLITAZONE IN MALE HEALTHY SUBJECTS
EU CTIS ID: 2025-521508-23-00
What this study is testing
To determine the DDI effect on the single-dose PK of oral leriglitazone as substrate when coadministered with gemfibrozil (Part A), itraconazole (Part B), or carbamazepine (Part C) as precipitants. To determine the effect of food (highfat breakfast) on the single-dose PK of oral leriglitazone (Part D).

Who can take part
You may be able to join if
- Healthy male participants (aged 18 to 50 years [inclusive]) with a BMI between 18 and 30 kg/m2 (inclusive).
- Male participants who are voluntarily able to give informed consent.
- Non-sterilized male participants with female partners of childbearing potential are eligible to participate if they agree to ONE of the following from Screening (signing the Informed Consent Form [ICF]) until at least 90 days after the last dose of study intervention. A) Are abstinent from penile-vaginal intercourse. B) Agree to use a male condom and have their partner use a contraceptive method with a failure rate of < 1% per year when having penile-vaginal intercourse with a woman of childbearing potential who is not currently pregnant (see Section 10.4). In addition, male participants must refrain from donating sperm from Screening (signing the ICF) until at least 12 weeks after the last dose of study intervention. The ICF will include information regarding potential effects on human spermatogenesis.
- Participants without any clinically significant finding upon completion of medical history, physical examination, and clinical laboratory test results, in the opinion of an Investigator.
- Ability and willingness to abstain from alcohol, caffeine, and methylxanthine containing beverages or food (eg, coffee, tea, cola, chocolate, energy drinks) from 72 hours (3 days) prior to admission to the clinical research center and during the stay in the clinical research center.
You likely can't join if
- All female participants will be excluded.
- Participants with any history or presence of suicidal ideation.
- Participants with any history or presence of malignancy.
- Participants who have a history or presence of sleep apnea.
