About this study

Official title: A 12-Month Extension to: A Randomized, Double-Blind, Double-Dummy, Parallel-Group, Multicenter Study to Evaluate and Compare the Effects of Once Weekly Alendronate and Risedronate on Bone Mineral Density in Postmenopausal Women With Osteoporosis

This study is to evaluate and compare the effects of Alendronate and Risedronate to treat women with postmenopausal osteoporosis. The primary hypothesis for this study is that in postmenopausal women with osteoporosis, treatment with oral alendronate 70 mg once weekly will produce a mean percent increase from baseline in hip trochanter bone mineral density (BMD) at 12 and 24 months which is greater than that observed with oral risedronate 35 mg once weekly.

Being tested
Alendronate, Risedronate 35 mg, Elemental Calcium, Vitamin D, Risendronate placebo
Medical subject headings
Osteoporosis, Postmenopausal

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Alendronate, Risedronate 35 mg and Elemental Calcium in people with Postmenopausal Osteoporosis, run by Organon and Co.

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 1 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: finished, as of the sponsor's last update on 14 Aug 2024. Status can change between updates, so confirm with the study contact before making plans.

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 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?

Mean percent change from baseline in hip trochanter bone mineral density (BMD) at 12 months (time frame: Baseline and 12 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 NCT00092014, which also lists 4 linked publications.

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 14 Aug 2024.
