About this study
Official title: Effects of Romosozumab on Bone Health in Women With Spinal Cord Injury and Osteoporosis
This two-year open-label pilot clinical trial will evaluate the efficacy and safety of romosozumab to treat bone loss in females with chronic spinal cord injury (SCI) and osteoporosis (OP). Participants will receive monthly injections of romosozumab during the first 12 months of the study. During the second year, participants will take oral alendronate tablets on a weekly basis.
Read the detailed description
This is a single-site, singe-arm, open-label pilot study to evaluate safety and efficacy of a sequential drug treatment (12 months of romosozumab injections followed by 12 months with alendronate tablets) to treat bone loss in women with chronic SCI and OP.
During the first year, participants will receive monthly subcutaneous injections of romosozumab 210 mg. This drug works by increasing bone formation and is FDA-approved for treating OP in post-menopausal women at high risk of fracture or those who did not benefit from using other available OP treatments. During the second year, participants will take weekly oral alendronate 70 mg. Alendronate is FDA-approved for the treatment of osteopenia and the treatment of OP in post-menopausal women and men as well as for the prevention and treatment of glucocorticoid-induced OP. In this study, it will be used to help maintain any increases in bone mass gained from the year of treatment with romosozumab.
Twelve participants will receive the study drug treatment, take daily supplements (calcium and vitamin D), and return to the research site for study visits over the course of two years. Computerized tomography (CT) imaging, dual-energy X-ray absorptiometry (DXA) imaging, and serum bone markers will be collected at various time points.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Romosozumab and Alendronate in people with Osteoporosis and Bone Loss, run by Northwestern University 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 14 inclusion and 18 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 24 Sep 2025. 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 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 24 Sep 2025). 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?
Change in Integral vBMC at the Knee (Distal Femur) (time frame: Baseline - 12 months). 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 NCT04708886, which also lists 3 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 24 Sep 2025.
