Summary

This phase 2 trial tests a drug called AGA2115 in 48 Chinese adults and adolescents with osteogenesis imperfecta (types I, III, IV), a condition that makes bones brittle. Participants receive one of three dose schedules by injection under the skin. The study checks for side effects and measures changes in bone density over 12 months.

What this could mean

Active substance

AGA2115 (a drug injected under the skin to strengthen bones)

What this could lead to

If successful, this could point toward a new treatment to improve bone density and reduce fractures in people with osteogenesis imperfecta.

What could go wrong

This is an early-phase trial with only 48 participants, so results may not apply to everyone. The drug may cause side effects or fail to improve bone strength significantly.
