Clinical Trial Summary

A single, ascending-dose design with five dose-cohorts of 8 subjects. Forty healthy adults aged 18 to 45, inclusive, will be recruited and admitted at multiple sites. Each subject will be randomized to receive either SAR440894 or matching placebo via 60-minute intravenous infusion. In each cohort of 8 subjects, the randomization ratio will be 6 active to 2 placebo, and 2 sentinel subjects (one from each active and placebo group) will be dosed first. Dosing of the next dose-cohort will be dependent on acceptable meeting predefined safety criteria in the preceding cohort. Each subject's participation will take place over approximately 150 days, not including the screening visit. There are no hypotheses for this phase I study. The primary objective will be to determine the safety of single ascending intravenous (IV) infusions of SAR440894 when administered in healthy adults.


Description:

A single, ascending-dose design with five dose-cohorts of 8 subjects. Forty healthy adults aged 18 to 45, inclusive, will be recruited and admitted at multiple sites. Each subject will be randomized to receive either SAR440894 or matching placebo via 60-minute intravenous infusion. In each cohort of 8 subjects, the randomization ratio will be 6 active to 2 placebo, and 2 sentinel subjects (one from each active and placebo group) will be dosed first. Dosing of the next dose-cohort will be dependent on acceptable meeting predefined safety criteria in the preceding cohort. Each subject's participation will take place over approximately 150 days, not including the screening visit. There are no hypotheses for this phase I study. The primary objective will be to determine the safety of single ascending intravenous (IV) infusions of SAR440894 when administered in healthy adults. The secondary objectives are: 1) to determine the pharmacokinetics (PK) of single ascending doses of 60-minute IV infusions SAR440894 in healthy adults and 2) to asses the immunogenicity of single ascending doses of 60-minute IV infusions SAR440894 in healthy adults.
