  • If male, patient must:
  • Agree to use an effective means of contraception (per site-specific guidelines) that is planned to continue for the duration of the study (one year).
  • Agree not to donate sperm until 6 months after dosing.
  • Willingness to comply with the protocol procedures for the duration of the study, including scheduled follow-up visits and examinations.
  • The criteria for enrollment in the study was originally limited to kidney donors with KDPI >85%. Over the last five years however, we have only transplanted a handful of those patients If we further restrict our patient pool to those who are not liver donors, our pool of possible donors will become even smaller, making the study very difficult, if not impossible, to complete. Furthermore, our knowledge of the pathophysiology of the complement system suggests that use of C1Inhibitor will improve liver outcomes by blunting the inflammatory response which can cause liver fibrosis and reperfusion injury. Since we have seen no negative effects on the liver in our preliminary non-human primate data, there is no need to exclude possible liver donors from our treatment.
  • Therefore, in order to increase feasibility of the study, we have now expanded the trial to include donors with a KDPI above 60% (rather than > 85%), since the rate of DGF in recipients of kidneys from KDPI between 60% and 85% is similar to the group >85%. In addition, we are now including liver recipients in the study, and will consent them if the donor has a viable liver in addition to the kidney(s). If we were to only include patients with KDPI above 85%, and kidney only donors, this trial would not be feasible.

About this study

Official title: A Phase I, Single Center, Randomized, Double-Blind, Placebo-Controlled Study to Evaluate Tolerability of C1 Inhibitor (CINRYZE) as a Donor Pre-treatment Strategy in Brain Dead Donors Who Meet a Kidney Donor Risk Index (KDRI) Above 60%

Limiting brain death-induced organ injury through a systemic anti- inflammatory medical management should allow for improvement in the quality of transplanted organs, and as a result, clinical improvement in post-transplant outcomes represented by a decrease in the incidence of delayed graft function (DGF) after transplantation.

The specific aim is to evaluate the effect of C1INH (CINRYZE) as a donor pre-treatment strategy to decrease systemic inflammation and decrease the incidence of DGF in Expanded Criteria Donors (ECD), currently identified as donors with Kidney Donor Profile Index (KDPI) greater than or equal to 60%.

Read the detailed description

This is a randomized, single-center double-blinded study.

Donor Pre-treatment Strategy:

The main objective is to identify the lowest dose that will allow an at least 80% decrease in the activity of classic pathway and Mannose-Binding Lectin (MBL) pathway of complement. The main objectives parallel observations in non-human primates in which animals receiving kidneys from donors in which activity of both classic and MBL pathways of complement were reduced by at least 50% with the use of C1 inhibitors displayed very mild or no delayed graft function after transplantation.

This trial has specifically been designed to evaluate the beneficial effect of C1INH in kidneys from deceased donors which have a high rate of delayed graft function. The selection of potential donors to be part of this study will be limited to the population of donors with a KDPI over 60%.

A total of 36 brain dead donors and 72 kidney recipients will be included in the study.

Most of the donors with a Kidney Donor Profile Index (KDPI) >60%, due to the fact that they are considered "extreme" donors, are not likely to be able to donate organs other than kidneys. They would certainly not be pancreas donors, and it is unlikely they would be lung donors. There is a small possibility that donors with a KDPI >60% could be potential liver donors. In the event that a donor liver is available for transplant, we will obtain written consent from the liver recipient, as we will from the kidney recipient(s) before the donor is dosed with the CINRYZE/placebo.

For this study:

All donors will come from within our service area. All kidney and livers will be allocated to be transplanted at the UW.

Stage 1: Collection of initial safety data prior to expanding the study to a broad cohort of patients.

3 non-randomized donors: Step 1: Two kidney only donors treated with 200 units/kg C1INH and heparin at 20 units/kg/h IV maintenance until organ recovery Step 2: Two donors of both liver and kidneys, treated with 200 units/kg C1INH and heparin at 20 units/kg/h IV maintenance until organ recovery The 8 kidneys and 2 livers in Stage 1 will be allocated to be transplanted only at UW.

Stage 2: PK Study, Safety and Outcome Data

36 donors will be randomized into 3 groups:

Group 1: Control group: standard donor management + vehicle treatment (n=12) Group 2: Standard donor management + C1INH at a dose of 200 U/Kg IV single dose (n=12) Group 3: Standard donor management + C1INH at a dose of 200 units/kg IV single dose and heparin at 20 units/kg/h IV maintenance until organ recovery (n=12)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Heparin and CINRYZE in people with Kidney Failure, run by University of Wisconsin, Madison.

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 28 inclusion and 20 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: status not confirmed, as of the sponsor's last update on 22 Oct 2020. Status can change between updates, so confirm with the study contact before making plans.

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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Luis Fernandez, MD ((608) 263-9903, luisf@surgery.wisc.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Lowest dose that will allow at least an 80% decrease in the activity of classic pathway and MBL pathway of complement in brain death donors with KDPI over 60%, with the purpose of reducing the incidence of delayed graft function. (time frame: over a 12 month period). 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 22 Oct 2020.
