Summary
Brief summary (as posted)
Primary Objectives: * To assess the excretion balance after oral and IV administration of \[14C\]-SAR439859 * To assess PK of total radioactivity, \[14C\] -SAR439859 and its metabolite (M7) after IV administration of \[14C\]-SAR439859 and, PK of radioactivity, SAR439859 and M7 after oral administration of SAR439859 alone or with \[14C\]-SAR439859 * To assess IV clearance and absolute bioavailability of SAR439859 using microdose of \[14C\]-SAR439859 tracer on top of a single tablet oral dose. * To assess relative bioavailability of SAR439859 given as tablet or solution Secondary objectives: * To collect samples in order to assess metabolic profile in plasma and excreta of SAR439859 after oral administration of \[14C\]-SAR439859 as solution, contribution in plasma of SAR439859 and metabolite relative to total radioactivity and identify metabolites (samples will be analyzed according to metabolic analysis plan and results will be documented in a separate report). * To assess safety and tolerance of SAR439859

Exclusion Criteria: Subject has clinical signs and symptoms consistent with COVID-19, e.g., fever, dry cough, dyspnea, loss of taste and smell, sore throat, fatigue or confirmed infection by appropriate laboratory test within the last 4 weeks prior to Screening. Subject who had severe course of COVID-19 (i.e., hospitalization, extracorporeal membrane oxygenation, mechanically ventilated). Frequent headaches and/or migraine, recurrent nausea and/or vomiting (for vomiting only: more than twice a month). Blood donation, any volume (usually approximately 500 mL), within 2 months before inclusion. Presence or history of 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). 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 5 cups or glasses per day). Subjects who are occupationally exposed to radiation as defined in the Ionizing Radiation Regulations 2017. Participation in a trial with \[13C\] or \[14C\] radiolabeled medication in the 12 months preceding the study. The above information is not intended to contain all considerations relevant to a patient's potential participation in a clinical trial.
