    Summary
    While the non-inferiority of teriparatide to alendronate was not confirmed, BMD increased significantly from baseline with teriparatide and alendronate by 5.09% and 4.04%, respectively (both p < 0.05), at 72 weeks.

    Summary · context
    The TOWER-GO study, a 72-week, multicenter, open-label, randomized controlled trial, was conducted in patients with GIOP to compare the effects of once-weekly teriparatide and once-weekly alendronate 35 mg on BMD.
    Summary · context
    Patients (N = 180) with GIOP for whom drug treatment was indicated according to the 2004 guidelines in Japan were randomized to receive once-weekly teriparatide (n = 89) or once-weekly alendronate (n = 91).

Studies that did not test the peptide alone1

In this study, Teriparatide (PTH 1-34) was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking Teriparatide (PTH 1-34).
