About this study

Official title: Randomized Controlled Study on the Benefits and Safety of Bisphosphonate Treatment in Childhood Cancer Survivors

Survivors of childhood cancers face a variety of long-term problems. The investigators' recent study found that osteoporosis and osteopenia were common among these patients. The factors leading to, as well as the best treatment option for, this morbidity are unclear. Bisphosphonates are currently the standard therapy for osteoporosis in the elderly. However, the efficacy and safety of bisphosphonates for treating osteoporosis in long-term cancer survivors have not been tested. The investigators hypothesize that alendronate, an orally active bisphosphonate, is efficacious and safe in the treatment of osteoporosis in these patients.

Read the detailed description

The modern treatment for childhood malignancy includes surgery and chemoradiotherapy either individually or in combination. Despite the great achievement in improving patient survival, these treatments also greatly enhance the adverse effects on the unfortunate children. Our research group has recently conducted a pioneer study on the bone mineralization and bone mineral density (BMD) study in longterm childhood cancer survivors in local patients who have completed anti-cancer treatment for at least five years. This landmark study showed that persistent treatment-related adverse effects on skeletal development are common (up to 50%) in local long-term survivors of childhood cancers. Thus, it is important during this critical period of rapid somatic growth in adolescents and young adults that these cancer survivors achieve their peak potential for bone mineralization and strengthening. In this proposed study, we investigate with a randomized and controlled study design on the efficacy of a second-generation oral bisphosphonate, alendronate, to improve BMD over a 36-week period in long-term survivors of childhood cancers in Hong Kong. In addition to alendronate, all subjects in the active and control groups will receive alfacalcidol (vitamin D) and calcium carbonate throughout the whole study period. The study results will help paediatric oncologists to decide on the optimal remedial treatments against osteoporosis in long-term cancer survivors.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Alendronate in people with Osteoporosis, run by Chinese University of Hong Kong at 1 site in Hong Kong.

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 4 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: status not confirmed, as of the sponsor's last update on 23 May 2008. 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 Hong Kong. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Ting Fan Leung, MBChB, MD (852-2632 2981, tfleung@cuhk.edu.hk), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The percent change in bone mineral density (BMD) at lumbar spine at 36-weeks in subjects who receive active and control treatments (time frame: 36 weeks). 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 23 May 2008.
