About this study

Official title: The Effects of 12-months of Denosumab on Bone Density, Quality and Strength in Prevalent Kidney Transplant Recipients

This is a Phase 2 Multi-Center Clinical Trial (safety and effectiveness trial) in 60 patients (40 denosumab; 20 placebo) who have had a kidney transplant for 12-months or longer with more than 30% of kidney function. The investigators will test whether denosumab safely improves bone mineral density (BMD) by dual-energy X-ray absorptiometry (DXA) and improves bone strength by high resolution peripheral quantitative computed tomography (HR-pQCT) in the subset of patients recruited at Columbia University Irving Medical Center. These data will inform the development and execution of a larger trial to test if denosumab prevents fractures in kidney transplant recipients.

Read the detailed description

Bone fractures are 3-times more common in kidney transplant recipients than in the general population and risk of dying after a hip fracture is 60% higher compared to kidney transplant recipients without a fracture. Unfortunately, there are no anti-fracture strategies that have been proven to be effective in double blinded randomized clinical trials for kidney transplant recipients. This is because some anti-fracture medications that are commonly used to treat osteoporosis and prevent fractures in the general population (i.e., bisphosphonates), may be harmful to the skeleton when kidney function is less than 30% of normal. In addition, intravenous bisphosphonates may be toxic to the kidneys, which further limits their utility in patients with a kidney transplant.

Denosumab, a monoclonal antibody against RANKL, inhibits osteoclast function and is not harmful to the kidney. Denosumab prevents fractures in men and women with age-related and glucocorticoid-induced osteoporosis. Recently, a non-blinded randomized trial of denosumab versus usual care during the first year of kidney transplantation in 90 patients reported the bone mineral density (BMD) measured by dual energy X-ray absorptiometry (DXA) increased at the spine and hip and that bone strength measured by high resolution peripheral quantitative computed tomography (HR-pQCT) increased in patients treated with denosumab. Adverse events in denosumab-treated patients included greater risk of urinary tract infections, diarrhea, and transient levels of low serum calcium that were asymptomatic. This study demonstrated that denosumab safely increased BMD at the spine and hip in new kidney transplant recipients. However, long-term kidney recipients, who comprise the vast majority of patients living with a transplanted kidney and who are also at increased risk of fracture, were not included.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Bone Mineral Density (BMD) Measured by Dual Energy X-ray Absorptiometry (DXA)

    BMD will be measured to determine if 1-year of treatment with denosumab changes BMD as measured by DXA.

    Measured: 12 months

  2. Estimated Bone Strength Measured by High Resolution Peripheral Quantitative Computed Tomography (HR-pQCT) Imaging

    Estimated bone mechanical competence will be measured by HR-pQCT.

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Denosumab Inj 60 mg/ml in people with Osteoporosis and Renal Osteodystrophy, run by Thomas Nickolas, MD MS at 3 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 16 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: stopped early, as of the sponsor's last update on 25 Jul 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 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. 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 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 25 Jul 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?

Bone Mineral Density (BMD) Measured by Dual Energy X-ray Absorptiometry (DXA) (time frame: 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?
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 25 Jul 2024.
