Is this trial a fit for you?

Likely a good fit

Ideal candidates are pediatric participants who were randomized to the romosozumab arm in Trial 20200105 and completed that trial through the Month 15 visit, with appropriate consent or assent.

Probably not a fit

Patients who never received romosozumab in the prior trial, who are currently enrolled in another investigational study, or who finished another investigational trial less than two years ago are unlikely to qualify or benefit from this follow-up.

What this trial studies

This Phase 3 interventional follow-up tracks participants with osteogenesis imperfecta who were randomized to the romosozumab arm and completed Trial 20200105 through the Month 15 visit. The primary focus is on post‑treatment safety monitoring after prior exposure to romosozumab, with protocol‑specified visits to collect adverse events and safety laboratory data. The protocol includes provision or monitoring of standard bone‑health supplements such as vitamin D and calcium. Enrollment is limited to those who completed the prior trial and meet local consent/assent requirements, and participants currently in other investigational trials or who recently finished other investigational trials are excluded.

Why it matters

Potential benefit: If the follow-up confirms an acceptable safety profile, it could support continued or expanded use of romosozumab in children with osteogenesis imperfecta and inform long‑term care decisions.

How similar studies have gone: Romosozumab has shown bone‑building benefits and a characterized safety profile in adults with osteoporosis, but pediatric use for osteogenesis imperfecta is novel and published pediatric data are limited.
