May 3, 2021 updated by: Novartis Pharmaceuticals

An Open Label, Reclast®/Aclasta®, Re-treatment of Relapsed Patients With Paget's Disease of Bone Who Participated in the CZOL446K2304 and CZOL446K2305 Core Registration Studies

The purpose of this study was to demonstrate that participants with Paget's disease of the bone who had responded to zoledronic acid treatment as participants in the core registration studies CZOL446K2304 and CZOL446K2305 and later experienced a relapse can be successfully treated with a 5 milligram (mg) infusion of zoledronic acid.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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
Percentage of Participants With Serum Alkaline Phosphatase Within the Normal Range at Month 6 Last Observation Carried Forward (LOCF)
Time Frame: Month 6
Normalization of serum alkaline phosphatase (SAP) occurred if the SAP measurement fell within the normal ranges. The lower and upper limits of normal ranges were 31 and 110 Units/Liter (U/L) for participants with age ≤ 58 years old and 35 and 115 U/L for participants with age > 58 years old, respectively. Last observation carried forward (LOCF) was defined as the last post-baseline SAP value prior to month 6 for a participant who did not have an SAP value at month 6.
Month 6

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
Time Frame
Percentage Change From Baseline in Serum Alkaline Phosphatase (SAP) Levels
Time Frame: Baseline, Months 3 and 6
The percentage change in SAP at Months 3 and 6 relative to baseline were measured.
Baseline, Months 3 and 6
Percentage of Participants With SAP Within the Normal Range
Time Frame: Months 3 and 6
Normalization of SAP occurred if the SAP measurement fell within the normal ranges. The lower and upper limits of normal ranges were 31 and 110 Units/Liter (U/L) for participants with age ≤ 58 years old and 35 and 115 U/L for participants with age > 58 years old, respectively.
Months 3 and 6
Number of Participants With At Least One or More Treatment-Emergent Adverse Events (TEAEs)
Time Frame: 6 months
Adverse event was the appearance or worsening of any undesirable sign, symptom, or medical condition that occurred after starting the study drug even if the event was not considered to be related to study drug. TEAEs were defined as AEs that were absent prior to, but occurred after the i.v. infusion of study drug. TEAEs also included those that were present prior to the i.v. study drug infusion (i.e., as part of the extended observation period) but occurred at an increased severity after the i.v. infusion of study drug.
6 months

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.

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.
