About this study

The purpose of this study is to see if treating patients who have high levels of donor specific alloantibodies post-transplant with bortezomib might prevent the development of transplant glomerulopathy and preserve allograft function.

Being tested
Bortezomib

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • BortezomibDrug

    Also called Velcade

    Patients randomized to bortezomib treatment will receive 2, 4-dose cycles of drug followed by a 2 month "hiatus". At the end of this time, subjects will be re-evaluated for the appropriateness of receiving a 3rd and 4th cycle of bortezomib. Bortezomib will be given subcutaneously (under the skin). If unable to give subcutaneously, bortezomib will be given as a single IV (injection into vein) over a time of 3 to 5 seconds. Patients will receive up to 4, four-dose cycles of 1.3 mg/m(2) (based on body surface area).

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Bortezomib in people with Disorder of Transplanted Kidney, run by Mark Stegall 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 28 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 28 Oct 2015. 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 9 Sep 2015). 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?

The Incidence of a Combined Endpoint of Death-censored Graft Loss or Greater Than 50% Reduction in Estimated Glomerular Filtration (eGFR) in Study Subjects. (time frame: 60 months after enrollment in the study). 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 28 Oct 2015.
