March 17, 2024 updated by: Sanofi

A First-in-human, Randomized, Double-blind, Placebo-controlled Study of the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of Ascending Single Doses of SAR443809 in Healthy Adult Subjects

Primary objective

  • The tolerability and safety of SAR443809 Secondary
  • The PK parameters of SAR443809
  • The PD activity of SAR443809
  • The immunogenicity of SAR443809

Study Overview

Detailed Description

Screening: up to 56 days (Day -56 to Day -2). Treatment: 1 day (treatment on Day 1, study observation period from Day -1 to Day 3). Follow-up and end of study: 105 days after IMP administration (follow up visits from Day 5 to Day 78; End of study visit on Day 106).
