Eligibility Criteria

5 Years - 17 Years (Child)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Ambulatory male or female children 5 to 18 years of age upon entry into screening
  • Clinical diagnosis of OI defined as a clinical history consistent with type I-IV OI as determined by presence of expected phenotype and lack of additional features unrelated to type I-IV OI

Exclusion Criteria

  • History of an electrophoresis pattern inconsistent with type I to type IV OI
  • History of known mutation in a gene other than collagen type I alpha/collagen type I alpha 2 (COL1AI/COL1A2) causing OI or other metabolic bone disease
  • History of other bone diseases that affect bone metabolism (eg, osteoporosis pseudoglioma syndrome, idiopathic juvenile osteoporosis, osteopetrosis, hypophosphatasia)
  • History of Kawasaki disease, rheumatic myocarditis, ischemic cardiomyopathy, inherited cardiomyopathies, nephrotic syndrome, familial hypercholesterolemia, stroke, or any thromboembolic disorder
  • Unhealed fracture as defined by orthopedic opinion
  • Symptoms associated with skull abnormalities such as basilar invagination, basilar impression or Chiari malformation
  • Prior treatment with anti-sclerostin antibody, fluoride or strontium, parathyroid hormone (PTH) within 12 months prior to screening, denosumab within 12 months or zoledronic acide with in 6 months prior to first dose
  • Less than 2 evaluable vertebrae by DXA evaluation in the region of interest, L1 L4, as confirmed by the central imaging laboratory.
  • Clinically significant valvular heart disease based on local echocardiogram (ECHO) results.

12. IPD Sharing Statement

Plan to Share IPD
Yes
IPD Sharing Plan Description
De-identified individual patient data for variables necessary to address the specific research question in an approved data sharing request
IPD Sharing Time Frame
Data sharing requests relating to this study will be considered beginning 18 months after the study has ended and either 1) the product and indication (or other new use) have been granted marketing authorization in both the US and Europe or 2) clinical development for the product and/or indication discontinues and the data will not be submitted to regulatory authorities. There is no end date for eligibility to submit a data sharing request for this study.
IPD Sharing Access Criteria
Qualified researchers may submit a request containing the research objectives, the Amgen product(s) and Amgen study/studies in scope, endpoints/outcomes of interest, statistical analysis plan, data requirements, publication plan, and qualifications of the researcher(s). In general, Amgen does not grant external requests for individual patient data for the purpose of re-evaluating safety and efficacy issues already addressed in the product labelling. Requests are reviewed by a committee of internal advisors, and if not approved, may be further arbitrated by a Data Sharing Independent Review Panel. Upon approval, information necessary to address the research question will be provided under the terms of a data sharing agreement. This may include anonymized individual patient data and/or available supporting documents, containing fragments of analysis code where provided in analysis specifications.
