What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage Change in Bone Mineral Density (BMD) of Femoral Neck at Year 6 Relative to Year 3

    The primary efficacy variable was the percentage change in BMD of the femoral neck as measured by dual x-ray absorptiometry (DXA) at Year 6 relative to Year 3. It was derived as 100 *(femoral neck BMD at Year 6 - femoral neck BMD at Year 3) / (femoral neck BMD at Year 3).

    Measured: Year 3 (Extension Baseline; Month 36 prior to the first treatment of the extension study) and Year 6 (Month 72; end of extension study)

Secondary outcomes (15)
  1. Bone Resorption and Formation Biochemical Markers at Year 4.5: P1NP

    The amount of serum n-terminal propeptide of type I collagen (P1NP) as determined by the central laboratory.

    Measured: Year 4.5

  2. Bone Resorption and Formation Biochemical Markers at Year 6: P1NP

    The amount of serum P1NP as determined by the central laboratory

    Measured: Year 6

  3. Percentage Change in BMD of Lumbar Spine at Year 4.5 Relative to Year 3

    The percentage change in BMD as measured by DXA at Year 4.5 relative to Year 3. It was derived as 100 * (BMD at Year 4.5 - BMD at Year 3)/(BMD at Year 3).

    Measured: Year 3 (Extension Baseline; Month 36 prior to the first treatment of the extension study) and Year 4.5 (Month 54)

  4. Percentage Change in BMD of Lumbar Spine at Year 6 Relative to Year 3

    The percentage change in BMD as measured by DXA at Year 6 relative to Year 3. It was derived as 100 * (BMD at Year 6 - BMD at Year 3)/(BMD at Year 3).

    Measured: Year 3 (Extension Baseline; Month 36 prior to the first treatment of the extension study) and Year 6

  5. Percentage Change in BMD of Distal Radius at Year 4.5 Relative to Year 3

    The percentage change in BMD as measured by DXA at Year 4.5 relative to Year 3. It was derived as 100 * (BMD at Year 4.5 - BMD at Year 3)/(BMD at Year 3).

    Measured: Year 3 (Extension Baseline; Month 36 prior to the first treatment of the extension study) and Year 4.5 (Month 54)

  6. Percentage Change in BMD of Distal Radius at Year 6 Relative to Year 3

    The percentage change in BMD as measured by DXA at Year 6 relative to Year 3. It was derived as 100 * (BMD at Year 6 - BMD at Year 3)/(BMD at Year 3).

    Measured: Year 3 (Extension Baseline; Month 36 prior to the first treatment of the extension study) and Year 6 (Month 72)

  7. Percentage Change in BMD of Femoral Neck, Total Hip and Trochanter at Year 4.5 Relative to Year 3

    The percentage change in BMD as measured by DXA at 4.5 relative to Year 3. It was derived as 100 * (BMD at Year 4.5 - BMD at Year 3)/(BMD at Year 3).

    Measured: Year 3 (Extension Baseline; Month 36 prior to the first treatment of the extension study) and Year 4.5 (Month 54)

  8. Percentage Change in BMD of Femoral Neck, Total Hip and Trochanter at Year 6 Relative to Year 3

    The percentage change in BMD as measured by DXA at Year 6 relative to Year 3. It was derived as 100 * (BMD at Year 6 - BMD at Year 3)/(BMD at Year 3).

    Measured: Year 3 (Extension Baseline; Month 36 prior to the first treatment of the extension study) and Year 6 (Month 72)

  9. Percentage of Patients With New and New/Worsening Morphometric Vertebral Fractures

    Lateral vertebral x-rays were performed at the final core study visit and at Year 6 and read by a central expert reader at a central imaging laboratory to assess for new or new/worsening morphometric vertebral fracture. The percentage of patients with new morphometric vertebral fractures (observed for the first time) and patients with either new or worsening morphometric vertebral fractures was calculated.

    Measured: Year 3 (Extension Baseline; Month 36 prior to the first treatment of the extension study) and Year 6

  10. Number of Participants With Incidence of Clinical Fracture

    Clinical fracture excludes finger, toe, and facial bone fractures. Clinical vertebral fracture includes thoracic spine fracture and lumbar spine fracture. Non-vertebral fracture excludes clinical vertebral, finger, toe, and facial bone fractures.

    Measured: Extension Baseline (Year 3; Month 36) to Year 6

  11. Qualitative Bone Biopsy Parameters

    Unpaired transiliac crest bone biopsy was performed for histomorphometry, which was obtained after double tetracycline labeling. No data were collected for Patients who received Placebo for the first 3 years of the study (Placebo 3 Zoledronic Acid 3).

    Measured: End of Study Visit at Year 6

  12. Change in Serum Creatinine From Baseline to 9-11 Days Post Year 3 Infusion

    Serum creatinine measurements performed by a central laboratory was used to evaluate acute changes in renal function 9-11 days after study drug infusion in Z6 patients compared to Z3P3 patients and in P3Z3 patients.

    Measured: Extension Baseline (Year 3; Month 36 prior to the first treatment of the extension study) to 9-11 days after the Year 3 infusion

  13. Change in Serum Creatinine From Baseline to 9-11 Days Post Year 4 Infusion

    Serum creatinine measurements performed by a central laboratory was used to evaluate acute changes in renal function 9-11 days after Year 4 study drug infusion.

    Measured: Extension Baseline (Year 3; Month 36 prior to the first treatment of the extension study) to 9-11 days after the Year 4 infusion

  14. Change in Serum Creatinine From Baseline to 9-11 Days Post Year 5 Infusion

    Serum creatinine measurements performed by a central laboratory was used to evaluate acute changes in renal function 9-11 days after Year 5 study drug infusion.

    Measured: Extension Baseline (Year 3; Month 36 prior to the first treatment of the extension study) to 9-11 days after the Year 5 infusion

  15. The Number of Participants With Clinically Significant Laboratory Parameters

    Evaluate the laboratory key profile such as Calcium, Creatinine and Urea. The number of patients with clinically significant calcium, creatinine and urea were reported.

    Measured: Extension Baseline (Year 3; Month 36 prior to the first treatment of the extension study) to Year 6

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Zoledronic Acid in people with Osteoporosis, run by Novartis at 31 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 28 Jun 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 31 sites in United States, Germany. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 20 Apr 2011). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage Change in Bone Mineral Density (BMD) of Femoral Neck at Year 6 Relative to Year 3 (time frame: Year 3 (Extension Baseline; Month 36 prior to the first treatment of the extension study) and Year 6 (Month 72; end of extension study)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00145327, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Jun 2011.
