- Brief Summary
The primary objective of this study is to evaluate the effect of romosozumab treatment for 12-months compared with bisphosphonate(s) on the number of clinical fractures at 12-months; the number of any fractures at 12-months and change in lumbar spine bone mineral density (BMD) Z-score at 6-months.

- Participant has provided informed consent/assent prior to initiation of any study specific activities/procedures.
OR
-
Participant's legally authorized representative has provided informed consent when the participant is legally too young to provide informed consent and the participant has provided written assent based on local regulations and/or guidelines prior to any study-specific activities/procedures being initiated.
-
Ambulatory male and female children and adolescents, age 5 to <18 years, including ambulatory with assistance as defined in the pediatric osteogenesis imperfecta (OI) population.
-
Clinical diagnosis of OI, defined as clinical history consistent with type I, III, or IV OI as determined by presence of expected phenotype (examples include: facial shape, voice, blue sclera, dentinogenesis imperfecta, typical radiographic features, fracture pattern) and lack of additional features unrelated to type I, III, or IV OI (eg, blindness, mental retardation, neuropathy, and craniosynostosis).
o If familial, also must be autosomal dominant.
-
Meets at least one of the following:
- 3 or more fractures within the previous 2 years, or
- 1 or more nonvertebral fracture(s) within the previous 2 years and at least 1 prevalent vertebral fracture, or
- 2 or more prevalent vertebral fractures.
Disease Related
- History of an electrophoresis pattern inconsistent with type I, III or IV OI.
- History of known mutation in a gene other than collagen type I alpha 1/collagen type I alpha 2 (COL1A1/COL1A2) causing OI or other metabolic bone disease.
- History of congenital dislocation of the radial head, interosseous membrane calcification, or exuberant callus formation.

Group Intervention Description Standard of Care Bisphosphonate Bisphosphonate Participants will receive bisphosphonates per local standard of care treatment regimens, as determined by the investigator for 12 months. Romosozumab Romosozumab Participants will receive romosozumab once a month (QM) for 12 months.
- Primary Outcome Measures
Name Time Method Number of Clinical Fractures 12 months Clinical fractures include clinical vertebral fractures and nonvertebral fractures.
Number of Any Fractures 12 months Fractures include new and worsening vertebral compression fractures, whether clinically silent or manifest, and nonvertebral fractures.
Change from Baseline to 12 Months in Lumbar Spine BMD Z-score Baseline and 12 months

The CHQ-PF-50 measures 50 items in the following domains: physical functioning, role/social limitations - physical, general health perceptions, bodily pain/discomfort, family activities, role/social limitations - emotional/behavioral, parent impact - time, parent ...
Change from Baseline in Childhood Health Assessment Questionnaire (CHAQ) Disability Score Baseline and 12 months The CHAQ measures how a child's condition affects their ability to function in daily life. The CHAQ measures 50 items in the following domains: physical functioning, role/social limitations - physical, general health perceptions, bodily pain/discomfort, family activities, role/social limitations emotional/behavioral, self-esteem, mental health, behavior, fam...
Change from Baseline in the Wong-Baker Faces Pain Rating Scale Baseline and 12 months The Wong-Baker Faces Pain Rating Scale is a horizontal pain scale that consists of six hand-drawn faces that range from a smiling "no hurt" face with a score of 0 to a crying "hurts worst" face with a score of 10. Greater change from baseline scores indicate greater pain experienced by the participant.
Serum Concentration of Romosozumab Day 1 to Month 12 Number of Participants who Experience Treatment-emergent Adverse Events (TEAEs) at 12 Months 12 months Any clinically signification change from baseline in laboratory values and vital signs after first dose will be recorded as a TEAE.
Number of Participants who Experience TEAEs from Month 12 to Month 15 Month 12 to Month 15 Any clinically signification change from baseline in laboratory values and vital signs after first dose will be recorded as a TEAE.
Number of Participants with Anti-drug Antibodies (ADA) to Romosozumab Up to 15 months Number of Participants who Experience TEAEs at 15 Months 15 months Any clinically signification change from baseline in laboratory values and vital signs after first dose will be recorded as a TEAE.
Number of Participants with a Narrowing from Baseline to 6 Months in the Intracranial Nerve Tract in the Cranium and Vault of the Skull Baseline and 6 months Measured in a subset of participants who receive cranial nerve computerized tomography (CT) scans.
