Long-term follow-up of individuals with Osteogenesis Imperfecta

Rare Diseases Clinical Research Network Brittle Bone Disease Consortium Longitudinal Study of Osteogenesis Imperfecta

Observational Baylor College of Medicine · NCT02432625

This study is tracking 1,000 people with Osteogenesis Imperfecta over five years to see how the condition affects their bones, spine, and dental health, which will help improve future treatments.

What this trial studies

This observational study aims to collect extensive natural history data on individuals diagnosed with Osteogenesis Imperfecta (OI), a rare brittle bone disorder. It will follow a cohort of 1000 participants over five years, assessing various clinical features, including the frequency of vertebral compression fractures, scoliosis, and dental health impacts on quality of life. Participants will undergo regular evaluations, including physical exams, dental assessments, and imaging tests. The study seeks to establish a foundation for future clinical studies by understanding the natural progression of OI.

Who should consider this trial

Good fit: Ideal candidates include individuals diagnosed with Osteogenesis Imperfecta through molecular analysis or those with suggestive clinical history and radiographs.

Not a fit: Patients with skeletal dysplasias other than Osteogenesis Imperfecta or those unable to attend follow-up visits may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of Osteogenesis Imperfecta and lead to improved management strategies for patients.

How similar studies have performed: While this study focuses on the natural history of OI, similar longitudinal studies in rare diseases have shown promise in understanding disease progression and improving patient outcomes.

Eligibility criteria

Show full inclusion / exclusion criteria
Natural History Study:

Inclusion Criteria:

* Individuals with OI diagnosed by molecular (DNA) analysis OR
* Individuals whose clinical history and radiographs are highly suggestive of OI, but whose diagnosis has not been verified by biochemical or molecular studies

Exclusion criteria:

* Individuals who are unable to return for their scheduled follow up visits.
* Individuals with skeletal dysplasias other than OI
* Individuals with OI and a second genetic or syndromic diagnosis

Vertebral Compression Fractures component Inclusion criteria

• Patients with nonsense or frameshift mutations in COL1A1 or COL1A2 of any age and clinical features of OI type I.

Exclusion criteria

* Use of a bone-acting treatment agent such as bisphosphonates, calcitonin, calcitriol, fluoride, etc., within one year of enrollment.
* Conditions other than Osteogenesis Imperfecta-HaploInsufficiency (OI-HI) affecting muscle and/or bone development (i.e. cerebral palsy, rickets)
* Nonsense or frame shift mutations in the final coding exons of COL1A1 or COL1A2, as this may not lead to haploinsufficiency.

Scoliosis in OI component:

Inclusion Criteria

* All study participants between the ages of 3 to 17 years OR
* Study participants 18 years and older with scoliosis

Dental and Craniofacial Abnormalities in OI component:

Inclusion Criteria • All subjects aged 3 years and older enrolled in the Longitudinal Study Exclusion Criteria Subjects who refuse the dental examination

Pregnancy in OI component:

Inclusion criteria

• Females of reproductive age with mutations in any known gene causing OI, who are contemplating pregnancy within 5 years of enrollment in the Natural History Study OR Females who are pregnant with available pre-pregnancy BMD (within 5 years prior to the first pregnancy visit).

Exclusion criteria

* Males
* Females who are peri-menopausal or menopausal
* Females who had gestations associated with higher order multiples.
