About this study

Official title: Desensitization for Preformed Anti-HLA Antibodies in Kidney Transplantation

To determine if deletional strategies will provide effective desensitization.

Read the detailed description

A prospective iterative trial of proteasome inhibitor (PI)-based therapy for reducing HLAantibody (Ab) levels was conducted in five phases differing in bortezomib dosing density and plasmapheresis timing. Phases included 1 or 2 bortezomib cycles (1.3mg/m2,6-8 doses), one rituximab dose and plasmapheresis. HLA Abs were measured by solid phase and flow cytometry (FCM) assays. Immunodominant Ab (iAb) was defined as highest HLA Ab level. Forty-four patients received 52 desensitization courses (7 patients enrolled in multiple phases): Phase 1 (n=20), Phase 2 (n=12), Phase 3 (n=10), Phase 4 (n=5), Phase 5 (n=5).

Study groupRoleWhat they receive
Phase 1, two stagesExperimentalPatients will receive 1 dose of rituximab, 4 doses of bortezomib and plasmapheresis. Rituximab will be given at a dose of 375 mg/m2 on day 32. Patients will receive 1.3 mg/m2 of bortezomib via intravenous push (IVP) over 3-5 seconds. Bortezomib will be administered on days 1, 4, 8, and 11.

Phase 5, single stageExperimentalPhase 5 evaluated even greater bortezomib dosing density by eliminating the inter-cycle dosing interval. Phase 5 evaluated eight consecutive doses of bortezomib with one dose of rituximab. Rituximab will be given at a dose of 375 mg/m2 on day -7. Patient will receive 1.3 mg/m2 of bortezomib via intravenous push (IVP) over 3-5 seconds. Bortezomib will be administered on days 1, 4, 8, 11, 14, 17, 20, and 23.

What is being measured

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

  1. Number of Living Donor Transplant Candidates That Are Transplanted

    Number of living donor transplant candidates who convert to a negative flow T- and B-cell crossmatch via desensitization and are subsequently transplanted

    Measured: 1 year post baseline

Secondary outcomes (3)
  1. Overall Safety of Bortezomib

    Incidence of grade 3 and above non-hematologic toxicities. Incidence of grade 4 hematologic toxicities. Incidence of all grades of peripheral neuropathy. Incidence of Cytomegalovirus (CMV), Polyomavirus Allograft Nephropathy (PVN), and Posttransplant Lymphoproliferative Disorder (PTLD).

    Measured: Study Day 62

  2. Number of Patients Whose Cytotoxic Panel Reactive Antibody (PRA) is Decreased by 50%

    Number of patients on the waiting list whose cytotoxic PRA is decreased by 50%.

    Measured: 46 days

  3. Acute Rejection Rate

    Acute rejection rate at 6 months of all desensitized and transplanted patients

    Measured: 6 months post transplant

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing plasmapheresis, Bortezomib and Rituximab in people with HLA Sensitization, run by University of Cincinnati 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 3 inclusion and 7 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 1 Apr 2016. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 26 Feb 2016). 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?

Number of Living Donor Transplant Candidates That Are Transplanted (time frame: 1 year post baseline). 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 1 Apr 2016.
