Brief summary: The purpose of this study is to assess in healthy adult male participants the effects of itraconazole on the pharmacokinetics of venglustat and to assess the safety and tolerability of venglustat with and without coadministration of itraconazole. The maximum duration for participants from screening is between 32 to 62 days.

Detailed description: Total study duration for participants is up to 62 days including screening up to 28 days, 1 day of treatment in period 1, washout of 7 days, 13 days of treatment in period 2, and follow up period 10-14 days after last dose.

Eligibility criteria: Inclusion Criteria: -Male participants, between 18 and 55 years of age, inclusive.

* Body weight between 50.0 and 100.0 kg, inclusive, body mass index between 18.0 and 30.0 kg/m2, inclusive.
* Certified as healthy by a comprehensive clinical assessment (detailed medical history and complete physical examination).
* Normal vital signs, electrocardiogram, and laboratory parameters.
* Having given written informed consent prior to undertaking any study-related procedure.
* Not under any administrative or legal supervision.
* Male participant, whose partners are of childbearing potential (including lactating women), must accept to use, during sexual intercourse, a double contraception method according to the following algorithm: (condom) plus (spermicide or intra-uterine device or hormonal contraceptive) from the inclusion up to 4 months after the last dosing.
* Male participant, whose partners are pregnant, must use, during sexual intercourse, a condom from the inclusion up to 4 months after the last dosing.
* Male participant has agreed not to donate sperm from the inclusion up to 4 months after the last dosing. Exclusion Criteria: Participants are excluded from the study if any of the following criteria apply:
* Any history or presence of clinically relevant cardiovascular, pulmonary, gastrointestinal, hepatic, renal, metabolic, hematological, neurological, osteomuscular, articular, psychiatric, systemic, ocular, or infectious disease, or signs of acute illness.
* Frequent headaches and/or migraine, recurrent nausea and/or vomiting (for vomiting only: more than twice a month).
* Blood donation, any volume, within 2 months before inclusion.
* Symptomatic postural hypotension excluding vasovagal episode associated with a blood draw.
* Presence or history of clinically significant drug hypersensitivity, or allergic disease diagnosed and treated by a physician.
* History or presence of drug or alcohol abuse (alcohol consumption more than 40 g per day on a regular basis).
* Smoking regularly more than 5 cigarettes or equivalent per week, unable to stop smoking during the study (occasional smoker can be enrolled). Excessive consumption of beverages containing xanthine bases (more than 4 cups or glasses per day).
* Any medication (including St John's Wort) within 14 days before inclusion or within 5 times the elimination half-life or pharmacodynamic half-life of the medication, with the exception of hormonal contraception or menopausal hormone replacement therapy; any vaccination within the last 28 days and any biologics (antibody or its derivatives) given within 4 months before inclusion.
* Positive result on any of the following tests: hepatitis B surface (HBs Ag) antigen, anti hepatitis C virus (anti-HCV) antibodies, anti-human immunodeficiency Virus 1 and 2 antibodies (anti-HIV1 and anti HIV2 Ab).
* Positive result on urine drug screen or urine alcohol test.
* Any contraindications to itraconazole, according to the applicable labeling.
