Participant Flow

68 subjects were enrolled from 05/12/2004 to 06/19/2014 at Columbia University Medical Center.

The first 6 participants in the study were randomly assigned to PTH1-84 100mcg daily, 100mcg every other day, and 100mcg every three days as a pilot project to determine the correct dosing regimen.

SECONDARY outcome

Timeframe: baseline versus two years

Population: Only 16 subjects had paired bone biopsies obtained at baseline and after 24 months of PTH(1-84) treatment.

Trabecular width was obtained from histomorphometric assessment of percutaneous iliac crest bone biopsy. Trabecular width is the thickness of individual pieces of the spongy bone section. The structure and microscopic organization of a small piece of biopsied pelvic bone was analyzed.
