About this study

Official title: Investigation on the Prevention of Periprosthetic Bone Loss After Total Hip Replacement by Annual Bisphosphonate Therapy: A Prospective Randomized Clinical Trial

Periprosthetic bone loss caused by stress-shielding effect, a phenomenon of bone atrophy under mechanical unloading after THR implantation, further compromises the longevity of implant. The prospective randomized study is aimed to investigate the periprosthetic bone loss after primary total hip replacements.

Read the detailed description

This study is a prospective, randomized, open-label clinical trial. The study will be performed in patients after obtaining informed consent. Group assignment is by drawing a sealed envelops based on random table. (1) Group 1: Experimental group 30 cases, Aclasta® (Zoledronic acid 5mg/100ml) is given intravenously on the 4th postoperative day and one year after the total hip replacement, (2) Group 2: Control group, 30 cases, no bisphosphonate is given to the patients. Only the unilateral coxarthrosis will be recruited for the study. Patients will be analyzed with (1) DXA study (2) Clinical assessment (Harris hip score and SF-12) (3) X-ray (4) serum marker of bone turnover. Patients will be scheduled for specified examinations preoperatively, postoperatively 6 weeks, 3 months, 6 months, 12 months, and 24 months.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Aclasta in people with Prevention of BMD Loss After THR and Serum Markers of Bone Turnover, run by Mel Shiuann-Sheng Lee at 1 site in Taiwan.

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 17 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 20 Jul 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Taiwan. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

bone mineral density [g/cm2] of the 7 Gruen zones (time frame: 5 years). The study lists 3 primary outcomes in all. 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 20 Jul 2016.
