About this study
The evaluation of efficacy is performed by laboratory monitoring of bone density and resorption markers and clinical monitoring of bone density improvement. This is a prospective, randomized, parallel group, single blind study of one year treatment with zoledronic acid every 6 months as compared to one year treatment with zoledronic acid every 3 months and to placebo every 3 months in patients with hemoglobin syndromes and risk of skeletal complications.

What is being measured
The primary outcome is the main question the study is designed to answer.
Bone density by means of bone densitometry with dual energy x-ray absorptiometry (DEXA) at three body sites (lumbar region, femoral head, wrist) prior to treatment initiation the start and at the end of treatment
N-telopeptide of type I collagen (NTx) levels, TRACP-5b, with ELISA, prior to the start of treatment initiation and every 3 or 6 months
Serum Bone alkaline phosphatase, Osteocalcin, OPG and S-RANKL with ELISA, prior to the start of treatment initiation, and every 3 or 6 months
Secondary outcomes (1)
Biochemistry (Ca, P, urea/creatinine, SGOT/SGPT, ALT, γGT), endocrine and cardiac test prior to the start of treatment initiation and at 6 and 12 month.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Zoledronic Acid in people with Thalassemia, run by Novartis Pharmaceuticals at 1 site in Greece.
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 2 inclusion and 2 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 1 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 1 site in Greece. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
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 density by means of bone densitometry with dual energy x-ray absorptiometry (DEXA) at three body sites (lumbar region, femoral head, wrist) prior to treatment initiation the start and at the end of treatment. 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?
On the ClinicalTrials.gov record for NCT00346242, which also lists 1 linked publication.
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 1 May 2012.
