Brief Summary:
Alendronate should be considered as an alternative therapy of osteogenesis imperfecta (OI) because it significantly increased areal bone mineral density (BMD) and its Z score, decreased fracture incidence, inhibited bone resorption biomarkers. Alendronate exerted beneficial roles in different age brackets, especially in young patients with OI.

Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Efficacy and Safety of Alendronate in Chinese Children or Adolescents With Osteogenesis Imperfecta: an Age Stratified Prospective Study
Study Start Date : March 2007
Actual Primary Completion Date : July 2011
Actual Study Completion Date : August 2014


Arm Intervention/treatment
Experimental: an open label, prospective, self-controlled study
Children or adolescents under the age of 18 years old with minor trauma fracture were recruited from 30 provinces of China. The diagnosis of OI was made by endocrinology department of Peking Union Medical College Hospital(PUMCH).
Drug: Alendronate
Alendronate was administrated as 70 mg/week orally (Fosamax, Merck Sharp & Dohme.LTD.).




Primary Outcome Measures :
  1. changes from baseline of areal BMD at lumbar spine and total hip [ Time Frame: baseline and 12,24,36 months ]
  2. annual clinical fracture incidence [ Time Frame: baseline and 12,24,36 months ]

Secondary Outcome Measures :
  1. changes of bone turnover biomarkers [ Time Frame: baseline and 6,12,24,36 months ]
  2. changes of height [ Time Frame: baseline and 12,24,36 months ]
