SAR439459 for Osteogenesis Imperfecta

Phase 1
Waitlist Available
Research Sponsored by Sanofi
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial
Must have
Participants who are clinically categorized as Type I or IV osteogenesis imperfecta with a previously documented pathogenic genetic variant in COL1A1 or COL1A2.
Body weight ≥30.0 kg.
Timeline
Screening 3 weeks
Treatment Varies
Follow Up up to 5 years

Summary

This trial tests SAR439459, a medicine that blocks certain proteins, in adults with Osteogenesis Imperfecta. The goal is to see if it can safely improve bone strength and density over several months.

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.
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.
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.
