About this study

Official title: Randomized, Double-blind, Safety and Efficacy Trial With Intravenous Zoledronic Acid for the Treatment of Paget's Disease of Bone Using Risedronate as a Comparator, Including an Extended Observational Period

The core study looked at the effect of Zoledronic Acid given once as an intravenous (i.v.) infusion compared to 60 days of oral Risedronate in patients with Paget's disease of bone. The effect was demonstrated in the reduction of serum alkaline phosphatase (SAP). The extended observation period included participants of the core study who responded to treatment.

What is being measured

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

  1. Number of Patients Who Achieve Therapeutic Response at 6 Months.

    Therapeutic response is defined as a reduction of at least 75% from baseline (Visit 1) in total serum alkaline phosphatase excess (difference between measured level and midpoint to the normal range) or normalization of serum alkaline phosphatase at the end of six months.

    Measured: 6 months

Secondary outcomes (10)
  1. Relative Change in Serum Alkaline Phosphatase (SAP) in Units Per Liter (U/L) at Day 28

    The percent change in serum alkaline phosphatase from baseline to day 28 was measured.

    Measured: Baseline and day 28

  2. Relative Change in Serum C-telopeptide (CTx) in ng/mL at Day 10

    The percent change in serum C-telopeptide from baseline to day 10 was measured.

    Measured: Baseline and day 10

  3. Relative Change in Urine Alpha C-telopeptide (α-CTx) in ug/mmol at Day 10

    The percent change in urine alpha C-telopeptide from baseline to day 10 was measured.

    Measured: Baseline and day 10

  4. Time to First Therapeutic Response

    A therapeutic response was defined as a reduction of at least 75% from baseline (Visit 1) in serum alkaline phosphatase excess (difference between measured level and midpoint to the normal range) or normalization of serum alkaline phosphatase.

    Measured: 182 days

  5. Number of Patients Who Achieved Serum Alkaline Phosphatase Normalization at Day 28 Relative to Baseline

    Normalization of serum alkaline phosphatase occurred if the serum alkaline phosphatase measurement fell within the normal range.

    Measured: Baseline and day 28

  6. Change in Pain Severity Score

    Change in pain severity score from Brief Pain Inventory-Short Form (BPI-SF). This scale values are 0 to 10, a lower score means little to no pain while a higher score means greater pain.

    Measured: Baseline and day 182

  7. Change in Pain Interference Score

    Change in pain interference score from Brief Pain Inventory-Short Form (BPI-SF). This scale values are 0 to 10, a lower score means little to no pain while a higher score means greater pain.

    Measured: Baseline and day 182

  8. Number of Participants With a Loss of Therapeutic Response During the Extended Observation Period

    Extended observation period. A therapeutic response is defined as a reduction of at least 75% from baseline in serum alkaline phosphatase excess or normalization of serum alkaline phosphatase.

    Measured: 8 years was the maximum

  9. Number of Participants With a Partial Disease Relapse During the Extended Observation Period

    Extended observation period. A partial disease relapse was defined as an increase in serum alkaline phosphatase >= 50% from the serum alkaline phosphatase measurement at month 6 and at least 1.25 times the upper normal limit.

    Measured: 8 years was the maximum

  10. Number of Participants With a Disease Relapse During the Extended Observation Period

    Extended observation period. A disease relapse was defined as the occurrence of a serum alkaline phosphatase level that was >= 80% of baseline serum alkaline phosphatase value.

    Measured: 8 years was the maximum

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Zoledronic Acid, Risedronate and Calcium and Vitamin D in people with Paget's Disease of Bone, run by Novartis Pharmaceuticals at 34 sites in 6 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 5 inclusion and 6 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 15 May 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 34 sites in United States, United Kingdom, Australia, Canada, New Zealand and 1 more country. 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. 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 7 May 2012). 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?

Number of Patients Who Achieve Therapeutic Response at 6 Months. (time frame: 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 15 May 2012.
