About this study
Official title: A Phase I/II Trial to Evaluate the Safety & Tolerability of Berinert® (C1 Inhibitor) Therapy to Prevent Complement-Dependent, Antibody-Mediated Rejection Post-Transplant in Highly-HLA Sensitized Patients"
Organ transplantation offers the only hope for a normal life for patients with end-stage renal disease on dialysis (ESRD). For the highly-sensitized patient, patients with antibodies to human leukocyte antigens (HLA), transplantation is extremely difficult or impossible since pre-formed antibodies will cause severe rejection and loss of transplanted organs. Approximately 30% of the transplant list in the U.S. is considered sensitized (have detectable antibodies to HLA antigens). These anti-HLA (anti-Human Leukocyte Antigen antibodies) pose a significant barrier to transplantation that has recently been successfully addressed using desensitization therapies with IVIG, rituximab and/or plasmapheresis (PE). Despite the success of these therapies, post-transplant antibody mediated rejection (AMR) and chronic Antibody Mediated Rejection (CAMR) remain significant problems. Recent data suggests that addition of Berinert (C1 Inhibitor) to post-transplant treatment regimen may significantly reduce incidence of Antibody Mediation Rejection.
Twenty highly-sensitized patients who have undergone desensitization treatment and are awaiting kidney transplant will be enrolled in the study. Once transplanted these patients will be started on the standard of care post-transplant immunosuppressive protocol. In addition patients will receive Berinert 20 units/ kg daily x 3 days, then twice weekly x 3 weeks. At the end of Berinert treatment a kidney biopsy will be performed. Subjects will be followed for 6 months to assess safety and efficacy of the study protocol.
Read the detailed description
Single center, Phase I/II, randomized The trial will examine the safety and efficacy of human C1 INH given post-transplant to reduce or prevent complement-dependent, antibody-mediated rejection (AMR) in 20 subjects (adult) who are highly-HLA sensitized (HS),(Panel Reactive Antibodies >30% (PRA), have undergone desensitization with intravenous immunoglobin (IVIG) + rituximab and/or plasmapheresis and are awaiting Living donor (LD)/ Deceased Donor (DD) kidney transplant. Once transplant offers are entertained, a donor-specific crossmatch will be performed to detect anti-HLA antibodies and donor-specific anti-HLA antibodies (DSA) which are associated with acute rejection or graft loss. (These anti-HLA (anti-Human Leukocyte Antigen antibodies) antibodies may result naturally or from previous pregnancy, transfusions, or prior transplants.) If acceptable crossmatches and Donor Specific Antibody levels are seen after desensitization, the patients will proceed to Living Donor/Deceased Donor transplantation. Patients receiving transplants will have pre-transplant labs obtained for C1 INH levels, Complement 3 (C3) and Complement 4 (C4) at transplant. In addition to the standard post-transplant immunosuppressive protocol, participating patients will receive placebo or 20 Units/kg C1 INH twice weekly X 4 weeks. At the end of the treatment, a protocol biopsy will be performed to assess the allograft for evidence of Antibody Mediated Rejection, including C4d staining. Since ~25% of highly sensitized patients experience Antibody Mediated Rejection post-transplant and 85% of these Antibody Mediated Rejection episodes occur in the 1st post-transplant month, we feel the assessment of the potential impact of C1 INH therapy is best assessed in this time period. After completion of the C1 INH therapy, patients will be followed for an additional 6 month to assess allograft function and Antibody Mediated Rejection episodes as well as Donor Specific Antibodies.
The subjects will be followed to determine the proportion who develop evidence of Antibody Mediated Rejection within 6 month of completion of the study. In addition we will asses the transplanted patients to determine the number who sustain a viable and functioning kidney allograft for 6 months. All subjects will be evaluated on an intent-to-treat basis. The subject accrual rate will be limited to no more than five subjects per month in the initial three months to assure safety to all subjects. Repeat laboratories will be performed at the completion of C1 INH therapy to determine effect on levels and correlation with any potential events.

What is being measured
The primary outcome is the main question the study is designed to answer.
Post-transplant Biopsy to Identify Rejection Episodes
Subjects will have a routine kidney biopsy 6 month after transplant to screen for episodes of acute rejection.
For purposes of this investigation, antibody-mediated rejection (AMR) is defined as follows:
- Deterioration of allograft function in a high-risk transplant recipient (i.e. sensitized patient with history of Donor Specific Antibodies) measured by serum Creatinine and estimated Glomerular Filtration Rate
- Association with the presence of Donor Specific Antibody (usually increasing in strength) measured by luminex techniques.
- Biopsy evidence of capillaritis, inflammation and C4d deposition.
Measured: 6 month
Secondary outcomes (3)
Serum Creatinine
Serum creatinine will be checked 6 months post transplant to monitor allograft function.
Measured: 6 months
Donor Specific Antibodies [DSA] Class I
Donor Specific Antibodies [DSAs] Class I will be checked 1, 3, and 6 months post transplant to monitor allograft function.
DSA will be measured using a relative intensity score (RIS) ranges from 0 points = No DSA; 2 points = <5000MFI (weak intensity); 5 points = 5000-10,000 MFI (moderate intensty); 10 points = >10,000MFI (strong intensity). Each DSA can have a score of 10 maximum. However, patients may have more than one DSA and points can add up to more than 10. this depends on how many DSAs [Class I and/or Class II] are present at the time of transplant and quarterly after transplant. Patients can have an infinite number of donor specific antibodies, this score can be higher than 10.
Measured: 6 months
Donor Specific Antibodies [DSA] Class II
Donor Specific Antibodies [DSAs] Class I will be checked 1, 3, and 6 months post transplant to monitor allograft function.
DSA will be measured using a relative intensity score (RIS) ranges from 0 points = No DSA; 2 points = <5000MFI (weak intensity); 5 points = 5000-10,000 MFI (moderate intensty); 10 points = >10,000MFI (strong intensity). Each DSA can have a score of 10 maximum. However, patients may have more than one DSA and points can add up to more than 10. this depends on how many DSAs [Class I and/or Class II] are present at the time of transplant and quarterly after transplant.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Organ transplantation offers the only hope for a normal life for patients with end-stage renal disease on dialysis (ESRD). For the highly-sensitized patient, patients with antibodies to human leukocyte antigens (HLA), transplantation is extremely difficult or impossible since pre-formed antibodies will cause severe rejection and loss of transplanted organs. Approximately 30% of the transplant list in the U.S. is considered sensitized (have detectable antibodies to HLA antigens). These anti-HLA (anti-Human Leukocyte Antigen antibodies) pose a significant barrier to transplantation that has recently been successfully addressed using desensitization therapies with IVIG, rituximab and/or plasmapheresis (PE). Despite the success of these therapies, post-transplant antibody mediated rejection (AMR) and chronic Antibody Mediated Rejection (CAMR) remain significant problems. Recent data suggests that addition of Berinert (C1 Inhibitor) to post-transplant treatment regimen may significantly reduce incidence of Antibody Mediation Rejection.
Twenty highly-sensitized patients who have undergone desensitization treatment and are awaiting kidney transplant will be enrolled in the study. Once transplanted these patients will be started on the standard of care post-transplant immunosuppressive protocol. In addition patients will receive Berinert 20 units/ kg daily x 3 days, then twice weekly x 3 weeks. At the end of Berinert treatment a kidney biopsy will be performed. Subjects will be followed for 6 months to assess safety and efficacy of the study protocol.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing C1 Esterase Inhibitor in people with Kidney Transplantation, run by Stanley Jordan, MD 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 6 inclusion and 16 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 21 Mar 2017. 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. 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 combined 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.
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 3 Aug 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?
