Exclusion criteria
Exclusion criteria: • Any prior use of strontium. • Calculated creatinine clearance < 30 mL/min. • Urine dipstick greater than/similar to 2+ protein at Visit 2 without evidence of contamination or bacteriuria. • Prior treatment with oral or i.v. bisphosphonates longer than 3 months consecutively.

| Main Objective: The primary objective is to demonstrate that combination therapy with once yearly i.v. zoledronic acid and daily subcutaneous injections of teriparatide is non-inferior to teriparatide treatment alone with respect to percentage increase in lumbar spine BMD at 52 weeks. If the non-inferiority is established, the superiority of the combination therapy is to be evaluated. ;Secondary Objective: The secondary objectives are: • To evaluate the effect of combination therapy with zoledronic acid and teriparatide compared to teriparatide alone on percent change in total hip BMD at 52 weeks. • To evaluate the effect of combination therapy with zoledronic acid and teriparatide compared to teriparatide alone on percent change of lumbar spine and total hip BMD at 13 and 26 weeks. • To evaluate the effect of combination therapy with zoledronic acid and teriparatide compared to zoledronic acid alone on percent change in lumbar spine and total hip BMD at 13, 26 and 52 weeks. • To evaluate the effect of combination therapy with zoledronic acid and teriparatide compared to teriparatide alone and zoledronic acid alone on serum biochemical markers (P1NP and ß-CTx) at 4, 8, 26, 39 and 52 weeks. ;Primary end point(s): To demonstrate that combination therapy with once yearly i.v. zoledronic acid (5 mg) and daily subcutaneous injections of teriparatide (20 micro gram) is non-inferior to teriparatide treatment alone with respect to percentage increase in lumbar spine BMD at 52 weeks. If the non-inferiority is established, the superiority of the combination therapy (ZOL+PTH) over teriparatide treatment alone is to be evaluated. | — |
