Primary Outcome Measures:
  • Percent Change From Baseline in Lumbar Spine Bone Mineral Density (BMD) at Week 52 [ Time Frame: Baseline through Week 52 ] [ Designated as safety issue: No ]
    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 ] [ Designated as safety issue: No ]
    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 ] [ Designated as safety issue: No ]
    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 ] [ Designated as safety issue: No ]
    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 ] [ Designated as safety issue: No ]
    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.
