Purpose

The purpose of this study is to assess the effects of zoledronic acid administered at the same time with teriparatide compared to zoledronic acid alone and teriparatide alone on bone mineral density (BMD) gain in the lumbar spine and total hip

Primary Outcome Measures:

Percent Change From Baseline in Lumbar Spine Bone Mineral Density (BMD) at Week 52 [ Time Frame: Baseline through Week 52 ]
BMD measurements of the lumbar spine (L1-L4) by Dual X-ray absorptiometry (DXA) were performed on all patients at screening, and Weeks 13, 26, and 52 (or early termination). Every attempt was made to obtain the BMD measurements at the scheduled visit. If this was not possible, a BMD measurement ± 7 days from the scheduled visit was obtained. For the Final DXA at Week 52, the window was 10 - 15 days prior to the final study visit. BMD scans were acquired locally and all results sent to a central reader for evaluation.

Secondary Outcome Measures:

Percent Change From Baseline in Lumbar Spine Bone Mineral Density (BMD) at Week 13 and Week 26 [ Time Frame: Baseline through Week 13 and Week 26 ]
BMD measurements of the lumbar spine (L1-L4) by Dual X-ray absorptiometry (DXA) were performed on all patients at screening, and Weeks 13, 26, and 52 (or early termination). Every attempt was made to obtain the BMD measurements at the scheduled visit. If this was not possible, a BMD measurement ± 7 days from the scheduled visit was obtained. For the Final DXA at Week 52, the window was 10 - 15 days prior to the final study visit. BMD scans were acquired locally and all results sent to a central reader for evaluation.
Percent Change From Baseline in Total Hip Bone Mineral Density (BMD) at Week 13, Week 26 and Week 52 [ Time Frame: Baseline through Week 13, Week 26 and Week 52 ]
BMD measurements of the total hip by Dual X-ray absorptiometry (DXA) were performed on all patients at screening, and Weeks 13, 26, and 52 (or early termination). Every attempt was made to obtain the BMD measurements at the scheduled visit. If this was not possible, a BMD measurement ± 7 days from the scheduled visit was obtained. For the final DXA at Week 52, the window was 10 - 15 days prior to the final study visit. BMD scans were acquired locally and all results sent to a central reader for evaluation.
Bone Resorption and Formation Biochemical Markers : N-terminal Propeptide of Type I Collagen (P1NP) [ Time Frame: At Baseline, Week 4, Week 8, Week 26, Week 39 and Week 52 ]
Specialized tests for markers of bone formation such as n-terminal propeptide of type I collagen (P1NP) were performed at Baseline, and Weeks 4, 8, 26, 39, and 52. The amount of serum P1NP was determined by the central laboratory.
Bone Resorption and Formation Biochemical Markers : Beta C-terminal Telopeptides of Type I Collagen (β-CTx) [ Time Frame: At Baseline, Week 4, Week 8, Week 26, Week 39 and Week 52 ]
Specialized tests for markers of bone formation such as β-CTx were performed at Baseline, and Weeks 4, 8, 26, 39, and 52. The amount of serum β-CTx was determined by the central laboratory.

Arms	Assigned Interventions
Active Comparator: Zoledronic acid plus teriparatide Zoledronic acid 5.0 mg/100 mL was administered via a peripheral intravenous site at Visit 2 (once at randomization) as a slow 15-minute infusion. Teriparatide is supplied as sterile, colorless clear, isotonic solution in a glass cartridge which is pre-assembled into a disposable pen device for subcutaneous injection. The pen device delivers 20 μg of teriparatide concurrently as daily subcutaneous injections for 52 weeks.	Drug: Zoledronic acid Zoledronic acid 5.0 mg in a ready-to-infuse plastic bottle with a total fill volume of 103 mL to allow an infusion of 100 mL total volume corresponding to 5 mg of zoledronic acid. Other Name: Reclast, Aclasta Drug: Teriparatide Teriparatide is supplied as sterile, colorless clear, isotonic solution in a glass cartridge which is pre-assembled into a disposable pen device for subcutaneous injection. Each pre-filled delivery device is filled with 3.3 mL to deliver 3 mL. Each mL contains 250 μg teriparatide (corrected for acetate, chloride, and water content), 0.41 mg glacial acetate acid, 0.10 mg sodium acetate (anhydrous), 45.4 mg mannitol, 3.0 mg Metacresol, and water for injection. In addition, hydrochloric acid solution 10% and/or sodium hydroxide solution 10% may have been added to adjust the product to pH 4. Each cartridge pre-assembled into a pen device delivers 20 μg of teriparatide per dose each day for up to 28 days. Other Name: Forteo/Forsteo™
Experimental: Zoledronic acid Zoledronic acid 5.0 mg/100 mL was administered via a peripheral intravenous site at Visit 2 (once at randomization) as a slow 15-minute infusion.	Drug: Zoledronic acid Zoledronic acid 5.0 mg in a ready-to-infuse plastic bottle with a total fill volume of 103 mL to allow an infusion of 100 mL total volume corresponding to 5 mg of zoledronic acid.

Active Comparator: Placebo zoledronic acid plus teriparatide Placebo zoledronic acid 100 mL intravenous (i.v.) (once at randomization) plus teriparatide 20 μg (daily subcutaneous injections administered concurrently through 52 weeks).

The pen device delivers 20 μg of teriparatide concurrently as daily subcutaneous injections for 52 weeks.	Drug: Placebo Zoledronic acid matched placebo as a 103 mL solution of sterile water (physiologic 0.9% normal saline) to allow an infusion of 100 mL total volume in a ready-to-infuse plastic bottle Drug: Teriparatide Teriparatide is supplied as sterile, colorless clear, isotonic solution in a glass cartridge which is pre-assembled into a disposable pen device for subcutaneous injection.
