- NCT06064539
- Lead Sponsor
- Sanofi
- Brief Summary
This is a Phase 1, single-center, open-label, non-randomized study to assess the effects of CYP2C8 inhibition using gemfibrozil, and CYP3A4 and CYP2C8 induction using rifampicin on the pharmacokinetics of SAR442168 in healthy male participants aged 18 to 45 years.
- Detailed Description
Study duration per participant approximately 16 days for Cohort 1 and approximately 18 days for Cohort 2.

Inclusion Criteria
- Male participant, between 18 and 45 years of age, inclusive.
- Body weight between 50.0 and 100.0 kg, inclusive, body mass index (BMI) between 18.0 and 30.0 kg/m2, inclusive.
- Having given written informed consent prior to undertaking any study-related procedure.
Exclusion Criteria

- Presence or history of drug hypersensitivity, or allergic disease diagnosed and treated by a physician. Participants with known hypersensitivity to any component of the IMP formulation or allergic disease diagnosed and treated by a physician.
- Any medication (including St John's Wort and ginseng) within 14 days before inclusion or within 5 times the elimination half-life or pharmacodynamic half-life of the medication, any vaccination within the last 28 days and any biologics (antibody or its derivatives) given within 4 months before inclusion.
- Any contraindications to gemfibrozil or rifampicin, according to the applicable labelling.
- Any subject who, in the judgment of the Investigator, is likely to be noncompliant during the study, or unable to cooperate because of a language problem or poor mental development.

Group Intervention Description Cohort 1 Tolebrutinib SAR442168 administered alone and together with gemfibrozil. 1 day washout for each administration of SAR442168. Cohort 2 Tolebrutinib SAR442168 administered alone and together with rifampicin. 1 day washout for each administration of SAR442168. Cohort 1 gemfibrozil SAR442168 administered alone and together with gemfibrozil. 1 day washout for each administration of SAR442168. Cohort 2 rifampicin SAR442168 administered alone and together with rifampicin. 1 day washout for each administration of SAR442168.
- Primary Outcome Measures
Name Time Method Pharmacokinetics: AUC of SAR442168 Cohort 1: day1 period 1 to day 7 period 2; Cohort 2: day1 period 1 to day 9 period 2 Area under the curve, reflects the concentration of drug
Pharmacokinetics: AUClast of SAR442168 Cohort 1: day1 period 1 to day 7 period 2; Cohort 2: day1 period 1 to day 9 period 2 AUC up to the last measurable concentration
- Secondary Outcome Measures
Name Time Method Pharmacokinetics: Cmax of gemfibrozil 1-O-glucuronide From Day 1 to Day 7 of Period 2 Pharmacokinetics: tmax of gemfibrozil From Day 1 to Day 7 of Period 2 Pharmacokinetics: tmax of rifampicin From Day 1 to Day 9 of Period 2 Pharmacokinetics: AUC of SAR442168 metabolite(s) Cohort 1: day1 period 1 to day 7 period 2; Cohort 2: day1 period 1 to day 9 period 2 Pharmacokinetics: Time to reach Cmax (tmax) of SAR442168 Cohort 1: day1 period 1 to day 7 period 2; Cohort 2: day1 period 1 to day 9 period 2 Pharmacokinetics: tmax of gemfibrozil 1-O-glucuronide From Day 1 to Day 7 of Period 2 Pharmacokinetics: Cmax of rifampicin From Day 1 to Day 9 of Period 2 Pharmacokinetics: tmax of SAR442168 metabolite(s) Cohort 1: day1 period 1 to day 7 period 2; Cohort 2: day1 period 1 to day 9 period 2 Pharmacokinetics: Cmax of gemfibrozil From Day 1 to Day 7 of Period 2 Numbers of participants with adverse events (AEs) From baseline to End of Study (i.e. Period 2 Day 16 days in Cohort 1, and Period 2 Day18 days in Cohort 2) Pharmacokinetics: Maximum plasma concentration observed (Cmax) of SAR442168 Cohort 1: day1 period 1 to day 7 period 2; Cohort 2: day1 period 1 to day 9 period 2 Pharmacokinetics: Cmax of SAR442168 metabolite(s) Cohort 1: day1 period 1 to day 7 period 2; Cohort 2: day1 period 1 to day 9 period 2
