The investigators have currently finished conducting an international multi-center trial that compares the efficacy and safety of pamidronate and zoledronate in the treatment of moderate to severe forms of Osteogenesis Imperfecta (OI). This trial has included only children above one year of age. The aim of the current study is to extend the observations of that currently finished study to infants below 1 year of age. Moreover, it is possible to administer zoledronate in a single short infusion instead of the three-day cycles with Pamidronate, therefore decreasing patient and family burdens with shorter stays in the hospital.
Drug: Zoledronic Acid
||Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Supportive Care
||An International, Multicenter, Open-label, Efficacy and Safety Trial of Intravenous Zoledronic Acid in Infants Less Than One Year of Age, With Severe Osteogenesis Imperfecta
Primary Outcome Measures:
- The primary objective of this trial is to assess the change in lumbar spine bone mineral density Z-score at month 24 relative to baseline in zoledronic acid treated infants compared to historical controls. [ Time Frame: 3 times during 10 visits within 2 years ] [ Designated as safety issue: Yes ]
Secondary Outcome Measures:
- To assess the effect of zoledronic acid on the number of clinical fractures &/or vertebral compressions that occur over a two year period compared to untreated historical controls in infants. [ Time Frame: 3 times during 10 visits within 2 years ] [ Designated as safety issue: Yes ]

Experimental: Treatment Arm (only)
Zoledronic acid infusion
Drug: Zoledronic Acid
Each patient is to receive an initial dose of zoledronic acid of 0.0125 mg per kg body weight, then subsequent doses of zoledronic acid at a dose of 0.025 mg per kg body weight once every 12 to 13 weeks for 104 weeks (total of 8 doses).
