Last verified: April 2012
  Purpose

The purpose of this study is to evaluate bone mineral density in adult subjects with hemophilia versus a comparator population without hemophilia (non-hemophilia age- and gender-matched database) by using the following diagnostic means: dual-energy X-ray absorptiometry (DXA) scanning, clinical scales, quality of life (QOL) scales and biomarkers. In addition to this osteoporosis study, hemophilic arthropathy of the knee with respect to loss of knee cartilage will also be explored by using magnetic resonance imaging (MRI substudy). No investigational product will be dispensed.

Primary Outcome Measures:
  • Baseline Endpoint: Z-Score by dual-energy X-ray absorptiometry (DXA) at baseline [ Time Frame: Baseline ] [ Designated as safety issue: No ]
  • Longitudinal Endpoint: Change in bone mineral density by DXA over 2 years [ Time Frame: 2 years ] [ Designated as safety issue: No ]
  • Longitudinal Endpoint: Rate of loss of knee cartilage parameters over 2 years by MRI [ Time Frame: 2 years ] [ Designated as safety issue: No ]

Enrollment: 3
Study Start Date: October 2011
Estimated Study Completion Date: April 2015
Estimated Primary Completion Date: February 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
DXA scan + MRI Other: DXA scan + MRI
This is a non-drug study. Subjects will receive a dual-energy X-ray absorptiometry (DXA) scan (in the main osteoporosis study) and will undergo magnetic resonance imaging (in the MRI substudy).

  • Willing and able to comply with the requirements of the protocol and is able to give informed consent

Additional inclusion criteria for MRI Substudy:

  • Baseline knee joint space width is >= 3mm at the medial or lateral aspect of either knee as measured by weightbearing fixed flexion PA X-ray
