Osteogenesis imperfecta (OI) is an inherited disease of the connective tissue. Symptoms are fractures, growth retardation, blue sclera, bad teeth, impaired hearing a.o. The aim of the present study is to investigate the effect of treatment of adult OI patients with bisphosphonate (zoledronic acid), parathyroid hormone (PTH) or placebo on bone mass, fracture risk and quality of life.

The investigators will therefore conduct a double blind, placebo controlled trial, taking genotype and previous antiresorptive therapy into account.

Further study details as provided by University of Aarhus:

Primary Outcome Measures:
  • Bone Mineral Density (BMD) [ Time Frame: Three years ]
    Dual-energy X-ray absorptiometry scans are performed at the lumbar spine, hip and whole body twice yearly. The value of the lumbar BMD is the primary outcome.

Secondary Outcome Measures:
  • Fracture risk [ Time Frame: Three years ]
    Participants are asked to report fractures throughout the study. Medical examination yearly with a focus on possible new fractures. Columnar x-ray before and after the study investigate new fractures.

Estimated Enrollment: 80
Study Start Date: November 2012
Estimated Study Completion Date: December 2021
Estimated Primary Completion Date: December 2021 (Final data collection date for primary outcome measure)
