Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label

Further study details as provided by Sanofi:

Primary Outcome Measures:
  • To assess the impact of physician's reinforcement using bone marker data on the treatment adherence of women with PMO. [ Time Frame: collected at week 10 and 22 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • to establish the profile of the unrecognized osteoporotic woman (PVD-, RF-) using a risk factor questionnaire for osteoporosis [ Time Frame: During the study conduct ] [ Designated as safety issue: No ]
  • to assess the decrease of type I collagen breakdown products(urinary NTX and serum CTX) [ Time Frame: after 10 and 22 weeks of treatment ] [ Designated as safety issue: No ]
  • To assess the change in BMD of both total hip and lumbar spine; [ Time Frame: at week 52 compared to baseline ] [ Designated as safety issue: No ]
  • osteoporosis-related genotyping. [ Time Frame: During the study conduct ] [ Designated as safety issue: No ]

Study Start Date: August 1999
Primary Completion Date: February 2002 (Final data collection date for primary outcome measure)

Ages Eligible for Study:   65 Years to 80 Years
Genders Eligible for Study:   Female
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Ambulatory women,
  • Caucasian, Oriental or Multiracial
  • not previously diagnosed for osteoporosis.

Exclusion Criteria:

  • Females of black descent and for the US african american are excluded because of the very low incidence of postmenopausal osteoporosis
  • and having used oral or parenteral glucocorticoids (>= 5 mg prednisone or equivalent per day) within 3 months of starting study drug or for more than one month within six months prior to study entry.
