Primary Outcome Measures:
  • % Change From Baseline BMD in L1-L4 Axial Lumbar Spine at Week 24 [ Time Frame: 24 weeks from baseline ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • % Change From Baseline in Bone Resorption Marker (CTx-1) at Week 24 [ Time Frame: 24 weeks from baseline ] [ Designated as safety issue: No ]
    Serum collagen type I (CTx-1) fragments generated during osteoclastic bone turnover are biomarkers for bone resorption. β-CrossLaps electrochemiluminescent sandwich immunoassay was used.

  • Systemic Absorption of PTH at Week 24 [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
    AUC: (PTH analog tablets timepoints - baseline to 5.75 hours) (Forsteo injection timepoints - baseline to 2 hours)

  • % Change From Baseline in Bone Formation Marker (P1NP) at Week 24 [ Time Frame: 24 weeks from baseline ] [ Designated as safety issue: No ]

Enrollment: 97
Study Start Date: February 2011
Study Completion Date: October 2011
Primary Completion Date: October 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: PTH analog tablet
PTH(1-31) 5 mg tablet, once daily
Drug: PTH analog
A recombinant 1-31 amino acid fragment of PTH.
Other Name: PTH(1-31)
Placebo Comparator: Placebo
Placebo matching tablet, once daily
Drug: Placebo
Active Comparator: Forsteo
Forsteo (teriparatide) 20 mcg SC Injection, once daily
Drug: Forsteo (Teriparatide)
A recombinant 1-34 amino acid fragment of PTH.
Other Name: Forteo (US)

Detailed Description:

The choice of a 24-week treatment period was based on published studies of PTH which demonstrate its potential to produce a statistically significant increase in BMD in patients with postmenopausal osteoporosis within that observation period.
