About this study
Official title: Bisphosphonates for Prevention of Post-Denosumab Bone Loss in Premenopausal Women With Idiopathic Osteoporosis
The primary goal of the study is to assess the extent to which bisphosphonate therapy will prevent decreases in bone mass that may occur after cessation of denosumab in premenopausal women with idiopathic osteoporosis (IOP) enrolled in AAAN0161 (FD05114) "Denosumab for the prevention of post-teriparatide bone loss in premenopausal women with idiopathic osteoporosis".
In addition, the investigator will observe participants for a second year off bisphosphonate therapy to assess duration of response.
The hypothesis is that bisphosphonate therapy with alendronate or zoledronic acid, initiated after recovery of bone remodeling activity, will prevent significant bone loss after discontinuing denosumab.
Read the detailed description
Osteoporosis in premenopausal women with normal menstrual function and no specific cause is termed idiopathic osteoporosis (IOP). IOP is a rare disease with an estimated prevalence of <200,000 affected premenopausal women in the United States.
Women with IOP completing at least one year and up to three years of denosumab (Protocol AAAN0161) will be offered participation in this open-label study in which they would choose whether to take oral alendronate 70 mg weekly for 12 months or a single intravenous dose of zoledronic acid 5 mg. Subjects and study personnel will be blinded to BMD outcomes until 12 months.
Discontinuation of denosumab is followed by substantial increases in bone turnover markers to well above baseline, bone resorption reaching twice baseline levels for about 6 months. Over the first 12 months off therapy, all the bone density gained on treatment is lost. Studies done at the institution has demonstrated the occurrence of multiple vertebral fractures in some patients who have stopped denosumab. Based upon these new fracture data, the Prolia label is currently recommending that consideration should be given to transition to another antiresorptive drug in patients stopping denosumab. The main goals of this extension study are to determine rates of bone loss and incidence of radiographic vertebral fractures during one year of bisphosphonate therapy (oral alendronate or intravenous zoledronic acid) initiated after completing denosumab.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The primary goal of the study is to assess the extent to which bisphosphonate therapy will prevent decreases in bone mass that may occur after cessation of denosumab in premenopausal women with idiopathic osteoporosis (IOP) enrolled in AAAN0161 (FD05114) "Denosumab for the prevention of post-teriparatide bone loss in premenopausal women with idiopathic osteoporosis".
In addition, the investigator will observe participants for a second year off bisphosphonate therapy to assess duration of response.
The hypothesis is that bisphosphonate therapy with alendronate or zoledronic acid, initiated after recovery of bone remodeling activity, will prevent significant bone loss after discontinuing denosumab.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Alendronate and Zoledronic Acid in people with IOP and Osteoporosis, run by Columbia University at 2 sites 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 1 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 8 May 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 8 May 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Difference in BMD at the Lumbar Spine (L1-4) Within Group (time frame: Baseline, 12 month). 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 NCT03396315, which also lists 23 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 8 May 2024.
