About this study

Official title: Comparative Antiresorptive Efficacy of Alendronate or Raloxifene Following Discontinuation of Denosumab

Osteoporosis remains a significant healthcare burden for the United States. Current FDA-approved osteoporosis treatments include teriparatide, abaloparatide, bisphosphonates, denosumab, and raloxifene.

Denosumab is a fully human monoclonal antibody that specifically binds to receptor activator of nuclear factor kappa-B ligand (RANKL). Denosumab potently suppresses osteoclastic activity but bone turnover rapidly normalizes and bone turnover marker levels can rebound above baseline levels after the drug is discontinued.

This study will help us determine the optimal duration and relative efficacy of two oral antiresorptive medications that are FDA-approved for treatment of postmenopausal osteoporosis (alendronate and raloxifene) in preventing the rebound increase in bone turnover that occurs after denosumab discontinuation.

Being tested

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing denosumab, alendronate and raloxifene in people with Osteoporosis, Postmenopausal and Osteoporosis, run by Massachusetts General Hospital at 1 site in United States.

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 3 inclusion and 11 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: under way, not looking for participants, as of the sponsor's last update on 7 Jun 2023. 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 United States. 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?

This study is still under way. Results are not available in the source record yet.

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?

Serum c-telopeptide (CTX) (time frame: Month 12 to 18 months). The study lists 2 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 NCT03623633, 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 7 Jun 2023.
