Study Summary

This trial will test the safety of a new drug, SAR439459, in adults with OI. The study will also look at how well the drug works and what effects it has on the body.

Who is the study for?
Adults with Osteogenesis Imperfecta (OI) types I or IV, who've had at least one bone fracture in the past decade or two since turning 18. They must weigh over 30 kg and not be pregnant, breastfeeding, or donating sperm. Participants need a documented genetic variant in COL1A1/COL1A2 and must consent to the study.Check my eligibility
What is being tested?
The trial is testing SAR439459, an antibody targeting TGFβ, given once via IV to see if it's safe and how it affects people with OI. It includes checking for side effects, how the body processes the drug (PK), its impact on bones (PD), bone density through DXA scans, and blood biomarkers over six months.See study design
What are the potential side effects?
Potential side effects are not specified but will be monitored throughout the trial. These may include typical reactions to monoclonal antibodies such as infusion-related reactions, immune system changes affecting organs' function, allergic responses or other unforeseen issues.
