SAR439459 is a human anti-Transforming growth factor β (TGFβ) monoclonal antibody. This phase 1 clinical study investigates the safety, tolerability, and activity of a single dose of SAR439459 in adult participants with OI. Participants will receive a single IV dose of SAR439459 with safety, pharmacokinetic (PK), and pharmacodynamic (PD) assessments over 24 weeks. There will be up to 3 dose cohorts. In addition to safety, tolerability, and PK assessments, bone mineral density (BMD) will be evaluated by dual-energy Xray absorptimetry (DXA) scan and a series of blood biomarkers will be monitored to document pharmacodynamic effects of the single dose of SAR439459.
