Effects of Teriparatide or Zoledronic Acid Treatment on Bone in Postmenopausal Osteoporotic Women
NCT00927186Jul 2009 to Apr 2012
Text and fields below are the sponsor's entries at ClinicalTrials.gov, shown as posted.
The purpose of this study is to investigate how teriparatide or zoledronic acid affects the bone of postmenopausal osteoporotic women after 6 months of treatment as determined by a bone biopsy sample taken from the iliac crest (upper part of the pelvis). After completing 12 months of treatment all participants are eligible to participate in an additional 12-month open label extension.

Mineralizing Surface/Bone Surface (MS/BS) in the Cancellous Compartment (CC) of Iliac Crest Bone Biopsies at 6 Months
Time frame · 6 months
MS/BS in CC is a measure of the proportion of BS on which new mineralized bone is deposited at the time of tetracycline (T) labeling and is calculated as sum of total extent of double label (DL) plus half the extent of single label (SL) divided by BS. Participants were given T for two 3-day periods, 14 days apart. T fluoresces under certain light and temporarily binds to new bone. New bone in the biopsy is seen as the amount of bone between 2 fluorescently T labeled lines under a microscope. DL indicates active bone formation, SL or no label (NL) suggests suppression of bone formation.
