Safety and Efficacy Trial With Zoledronic Acid for the Treatment of Paget's Disease of Bone, Including an Extended Observation Period

May 9, 2012 updated by: Novartis Pharmaceuticals

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Patients Who Achieve Therapeutic Response at 6 Months.
Time Frame: 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.
6 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description

Number of Participants With a Loss of Therapeutic Response During the Extended Observation Period
Time Frame: 8 years was the maximum
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.

Relative Change in Serum Alkaline Phosphatase (SAP) in Units Per Liter (U/L) at Day 28
Time Frame: Baseline and day 28

Baseline and day 28
Relative Change in Serum C-telopeptide (CTx) in ng/mL at Day 10
Time Frame: Baseline and day 10

Change in Pain Interference Score
Time Frame: Baseline and day 182

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
